VIP-FE-TX Installation and Configuration

Product Numbers: VIP-FE-TX(=)

This configuration note is a standalone publication that provides instructions for installing, configuring, and maintaining the Fast Ethernet Versatile Interface Processor (VIP-FE-TX) in your Cisco 7000 series and Cisco 7500 series routers.

The VIP-FE-TX operates with the CxBus in the Cisco 7000 series and CyBus in the Cisco 7500 series, and requires that the host Cisco 7000 series and Cisco 7500 series router is running Cisco Internetwork Operating System (Cisco IOS) Release 11.1(1) or later, or a Cisco-approved beta version of Cisco IOS Release 11.1 or later.


Note The entire VIP-FE-TX card, with port adapters installed, is a field-replaceable unit (FRU). Individual port adapters are not available as spare parts.

Included are steps for VIP-FE-TX hardware installation, and basic VIP-FE-TX configuration steps and examples for configuring the individual interfaces on a new VIP-FE-TX.

This publication has two main sections:

You need only refer to the information that is specific to your FE-TX port adapter or to that which applies to specific VIP motherboard functionality. A table of contents is included on page 2 so you can more easily find what you need.

Versatile Interface Processor Functions

The following sections describe the Versatile Interface Processor (VIP) and discuss VIP-specific features and functions, such as installing and removing the VIP, installing and removing port adapters, and using and configuring common VIP interface functions.

What is the VIP?

The VIP is a new interface processor for use with the Cisco 7000 series and Cisco 7500 series routers, and it installs in the interface processor slots in your Cisco 7000 series or 7500 series router. The VIP uses a single motherboard with up to two port adapters. The VIP port adapters provide the individual LAN, WAN, or LAN/WAN interface ports. The VIP can be removed from a chassis while power is on and the system is operating.

Caution The VIP supports online insertion and removal (OIR), which allows you to remove and replace a VIP without first shutting down the system. Online insertion and removal maximizes router availability by letting you add or remove VIPs during system operation; however, the system may indicate a hardware failure if you fail to follow proper procedures. To help avoid problems with the installation, review the functional description in the section "Online Insertion and RemovalAn Overview" on page 14, and follow the VIP installation steps carefully.

Note 
The VIP port adapters themselves do not support OIR, nor are they FRUs.

The VIP uses a Reduced Instructions Set Computing (RISC), Mips 4600 processor for high performance, and has an internal operating frequency of 100 megahertz (MHz) and a 50-MHz system bus interface. The VIP has 8 megabytes (MB) of dynamic random access memory (DRAM) as the default DRAM configuration.

Figure 1 shows a VIP-FE-TX. The VIP firmware (microcode), which contains card-specific software instructions, resides in a Flash memory device in socket location U17. For pinouts, refer to the section "FE-TX Port Adapter Receptacles, Cables, and Pinouts" on page 33. Single in-line memory modules contain the DRAM. You can install VIPs in any available interface processor slots in your Cisco 7000 series or Cisco 7500 series router.

Note In the Cisco 7000, Cisco 7507 and Cisco 7513 chassis, the VIP is installed vertically. In the Cisco 7010 and Cisco 7505 chassis, the VIP is installed horizontally. Port adapters have a handle attached, but this handle is not shown to allow a full view of the detail on the port adapter's faceplate.

VIP Software Prerequisites

The VIP requires that the host Cisco 7000 series and Cisco 7500 series router is running Cisco Internetwork Operating System (Cisco IOS) Release 11.1(1) or later, or a Cisco-approved beta version of Cisco IOS Release 11.1 or later.


Note The latest Cisco IOS release is available via anonymous File Transfer Protocol (FTP) from ftp/beta111_dir@ftp.cisco.com. Detailed information about the latest Cisco IOS release can be found in the ASCII file vip1-readme, which is also available via FTP from ftp.cisco.com in the directory /ftp/beta111_dir. This ASCII file includes information and instructions on how to get the current Cisco IOS software images and VIP microcode. To access information located in Cisco Information Online (CIO), refer to the section "
Cisco Information Online" at the end of this publication.

VIP Hardware Prerequisites

The VIP operates with the CxBus in the Cisco 7000 series and CyBus in the Cisco 7500 series, and operates with the optional RSP7000 and RSP7000CI RSP-based processor modules in the Cisco 7000 series routers: Cisco 7000 and Cisco 7010. The VIP will also operate with the Route Processor RP) and Switch Processor (SP) in the Cisco 7000 series routers. The VIP operates with all RSP-based processor modules currently shipping in the Cisco 7000 series and Cisco 7500 series routers: Cisco 7505, Cisco 7507, and Cisco 7513.

What is the Cisco 7000 Family?

For the Cisco 7000 family of routers, which includes the Cisco 7000 series and Cisco 7500 series routers, network interfaces reside on modular interface processors, including the VIP, which provide a direct connection between external networks and the high-speed CxBus in the Cisco 7000 series and the high-speed CyBus in the Cisco 7500 series.

In all systems, the remaining slots support any combination of network interface types: Ethernet attachment unit interface (AUI), Ethernet 10BASE-T, Fast Ethernet 100BASE-TX, Asynchronous Transfer Mode (ATM), Token Ring, multichannel applications, Fiber Distributed Data Interface (FDDI), channel attachment, serial, or High-Speed Serial Interface (HSSI), and all VIP-based interfaces.

Cisco 7000 Series

Figure 2 and Figure 3 show the rear of the Cisco 7000 series routers: the seven-slot Cisco 7000 and the five-slot Cisco 7010, respectively. In the Cisco 7000 series, two slots are reserved for the SP (or SSP) and RP, or for the 7000 Series Route Switch Processor (RSP7000) and the 7000 Series Chassis Interface (RSP7000CI). The remaining slots are for interface processors: slots 0 through 4 in the Cisco 7000, and slots 0 through 2 in the Cisco 7010.

VIP Port Adapter Hardware Configuration Overview

The port adapter attaches to the VIP motherboard. (See Figure 7.) The port adapter contains the physical connections for the VIP interface types to connect to your network.


Figure 7: VIP with One FE-TX Port Adapter (Product Number VIP-FE-TX[=])



Note The VIP-FE-TX must have a blank port adapter installed in the second port adapter slot location, as shown in
Figure 7.

Following are the VIP port adapters by interface type:

Following are the supported electrical interfaces:


Note VIP-FE-TX is a fixed configuration. The FE-TX port adapter is not available as a spare part. The entire VIP-FE-TX assembly is a FRU. The FE-TX port adapter has a handle attached, but this handle is not shown to allow a full view of the detail on the port adapter's faceplate.
Caution To prevent system problems, do not remove port adapters from the VIP motherboard or attempt to install other port adapters on the VIP motherboard.

When only one port adapter is installed on a VIP, as with the VIP-FE-TX, a blank port adapter must fill the empty slot to allow the VIP and router chassis to conform to electromagnetic interference (EMI) emissions requirements, and so that air flows through the chassis properly. The blank port adapter is shown in Figure 8.


Figure 8: Blank Port Adapter, Partial Front View


VIP Microcode Overview

The VIP microcode (firmware) is an image that provides card-specific software instructions. A Flash memory device in socket U17 of the VIP contains the default microcode boot image. The router supports downloadable microcode, which enables you to upgrade microcode versions by downloading new microcode images, storing them in system Flash memory, and instructing the system to load its image from Flash instead of the default VIP image. (The RP in the Cisco 7000 and 7010 loads software from ROM or Flash memory; the RSP loads software from Flash only.) You can store multiple images for an interface type and, with a configuration command, instruct the system to load any one of them or the default ROM image. All interfaces of the same type (VIP, and so on) will load the same microcode image, either from the default ROM image or from a single image stored in system Flash. Although multiple microcode versions for a specific interface type can be stored concurrently in Flash, only one image can load at startup. The show controllers cbus command displays the currently loaded and running microcode version for the SP or SSP (in the Cisco 7000 series routers), each interface processor, and VIP. The show startup-config EXEC command shows the current system instructions for loading microcode at startup.

Software and interface processor microcode images are carefully optimized and bundled to work together. Overriding the bundle can result in system incompatibilities. We recommend that you use the microcode included in the software bundle. For a complete description of microcode and downloading procedures, refer to the section "Upgrading VIP Microcode" on page 24.

VIP Installation Prerequisites

This section provides a list of parts and tools you will need to perform the installation, and it also includes safety and ESD-prevention guidelines to help you avoid injury and damage to the equipment. This section also provides a detailed description of the OIR function to help you perform online installation successfully and avoid error message and system restarts. If you are installing a new VIP, be sure to review the equipment descriptions and distance limitations in the section "FE-TX Port Adapter Receptacles, Cables, and Pinouts" on page 33 when preparing your site and planning network connections.

List of Parts and Tools

You need the following tools and parts to install a VIP. If you need additional equipment, contact a service representative for ordering information.

Safety Guidelines

Following are safety guidelines that you should follow when working with any equipment that connects to electrical power or telephone wiring.

Electrical Equipment Guidelines

Follow these basic guidelines when working with any electrical equipment:

Telephone Wiring Guidelines

Use the following guidelines when working with any equipment that is connected to telephone wiring or to other network cabling:

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. A processor module comprises a printed circuit board that is fixed in a metal carrier. Electromagnetic interference (EMI) shielding, connectors, and a handle are integral components of the carrier. Although the metal carrier helps to protect the board from ESD, use a preventive antistatic strap whenever handling a processor module.

Following are guidelines for preventing ESD damage:

Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohms.

Online Insertion and Removal—An Overview

The OIR feature allows you to remove and replace a VIP board while the system is operating; you do not need to notify the software or shut down the system power.


Note The VIP port adapters themselves do not support OIR, nor are they FRUs.

This section describes mechanical functions of system components, emphasizes the importance of following correct procedures to avoid unnecessary board failures, and is for background only; specific VIP procedures follow in the section "VIP Installation" on page 17.

Each interface processor contains a receptacle with which it connects to the system backplane. Each backplane connector comprises a set of tiered pins, in three lengths. The pins send specific signals to the system as they make contact with the card. The system assesses the signals it receives and the order in which it receives them to determine what event is occurring and what task it needs to perform, such as reinitializing new interfaces or shutting down removed ones.

For example, when inserting an interface processor, the longest pins make contact with the backplane first, and the shortest pins make contact last. The system recognizes the signals and the sequence in which it receives them. The system expects to receive signals from the individual pins in this logical sequence, and the ejector levers help to ensure that the pins mate in this sequence.

When you remove or insert an interface processor, the backplane pins send signals to notify the system, which then performs as follows:

    1. Rapidly scans the backplane for configuration changes and does not reset any interfaces.

    2. Initializes all newly inserted interface processors, noting any removed interfaces and placing them in the administratively shut down state.

    3. Brings all previously configured interfaces on the interface processor back to the state they were in when they were removed. Any newly inserted interfaces are put in the administratively shut down state, as if they were present (but unconfigured) at boot time. If a similar interface processor type has been reinserted into a slot, then its ports are configured and brought on line up to the port count of the original interface processor.

The system brings on line only interfaces that match the current configuration and were previously configured as up; all others require that you configure them with the configure command. OIR functionality enables you to add, remove, or replace interface processors with the system online, which provides a method that is seamless to end users on the network, maintains all routing information, and ensures session preservation.

The function of the ejector levers (see Figure 9) is to align and seat the card connectors in the backplane. Failure to use the ejector levers and insert the interface processor properly can disrupt the order in which the pins make contact with the card or interface processor. Follow the VIP installation and removal instructions carefully, and review the following examples of incorrect insertion practices and their results:

It is also important to use the ejector levers when removing an interface processor to ensure that the backplane connector pins disconnect from the card or interface processor in the logical sequence expected by the system. Any interface processor that is only partially connected to the backplane can hang the bus. Detailed steps for correctly performing OIR are included with the following procedures for installing and removing the VIP.


Figure 9: Ejector Levers and Captive Installation Screws on the VIP (Horizontal Orientation Shown)



Note The VIP is oriented horizontally in the Cisco 7010 and Cisco 7505 and vertically in the Cisco 7000, Cisco 7507, and Cisco 7513.

VIP Installation

The following sections describe the procedures for removing or installing a VIP in the Cisco 7000 series and Cisco 7500 series routers. The functionality is the same for each router model; therefore, the term the chassis will be used except where specific model issues arise. The OIR function allows you to install and remove a VIP without first shutting down the system; however, you must follow the instructions carefully. Failure to insert the VIP properly can cause system error messages indicating a board failure. For a complete description of OIR, refer to the section "Online Insertion and RemovalAn Overview" on page 14.

Each unused interface processor slot contains an interface processor filler (which is an interface processor carrier without an interface board) to keep dust out of the chassis and to maintain proper air flow through the interface processor compartment. If you are installing a new VIP that is not a replacement, you must first remove the interface processor filler from an unused slot; proceed to the next section "Removing an Interface Processor Filler." If you are replacing a VIP or upgrading the microcode Flash EPROM on a VIP, proceed to the section "Removing a VIP."


Note If you suspect that a port adapter has failed, you must replace the entire VIP processor module. Port adapters are not available as FRUs.
Caution If you use the VIP with a single port adapter, the port adapter must be in slot 0 for the VIP to function properly. A single port adapter in slot 1 will not be recognized by the system.

Removing an Interface Processor Filler

Select an unused interface processor slot for the new VIP and remove the interface processor filler as follows:


Step 1   Choose an available slot for the VIP and make a note of it.


Step 1   Use a screwdriver to loosen the captive installation screws on the interface processor filler. (See Figure 9.)

Step 2   Place your thumbs on both ejector levers and simultaneously pull them both outward to release the VIP from the backplane connector (in the opposite direction from that shown in Figure 9c).

Step 3   Grasp the handle with one hand and pull the filler straight out of the slot, keeping your other hand under the carrier to guide it. (See Figure 10.) Keep the carrier parallel to the backplane.

Step 4   Store the interface processor filler for future use.

To help prevent dust and contaminants from entering the chassis, do not leave the interface processor slot open. Immediately proceed to the section "Installing a VIP" on page 19.

Removing a VIP

Remember, the VIP supports OIR; therefore, you need not shut down the interface or the system power when removing a VIP. If you are replacing a failed VIP, remove the existing board first, then replace the new VIP in the same slot.

Figure 10 shows proper handling of an interface processor during installation.


Figure 10:
Handling Processor Modules for Installation and Removal (Horizontal Orientation Shown)


To remove a VIP, follow these steps:


Step 1   If you are replacing a failed VIP, disconnect all cables from the VIP ports; however, if you are only moving a VIP to another slot, this step is not necessary.

Step 2   Use a screwdriver to loosen the captive installation screws at both ends of the VIP. (See Figure 9.)

Caution Always use the ejector levers to remove or install the VIP. Failure to do so can cause erroneous system error messages indicating a board failure.

Step 3   Place your thumbs on the ejector levers and simultaneously pull both of the ejectors outward (in the opposite direction from that show in Figure 9c) to release the VIP from the backplane connector.

Step 4   Use the VIP handle to carefully pull the VIP straight out of the slot, keeping your other hand under the carrier to guide it. (See Figure 10.) Keep the VIP parallel to the backplane.

Step 5   Place the removed VIP on an antistatic mat or foam pad, or place it in an antistatic bag if you plan to return it to the factory.

Step 6   If the interface processor slot is to remain empty, install a filler (MAS7K-BLANK) to keep dust out of the chassis and to maintain proper air flow inside the chassis. Do not leave the interface processor slot open. Immediately proceed to the section "Installing a VIP."

Installing a VIP

The VIP slides into the open interface processor slot and connects directly to the backplane. The interface processors are keyed to guide pins on the backplane, so the VIP can be installed only in an interface processor slot. Figure 9 shows the functional details of inserting an interface processor and using the ejector levers. Figure 10 shows proper handling of an interface processor during installation.

Caution Remove or insert only one interface processor at a time. Allow at least 15 seconds for the system to complete its discovery and initialization before removing or inserting another interface processor. Disrupting the sequence before the system has completed verification can cause the system to interpret hardware failures.

Follow these steps to install a VIP:


Step 1   Ensure that a console terminal is connected to the console port (on the RP or RSP) and that your console is turned ON.

Step 2   Hold the VIP handle with one hand and place your other hand under the carrier to support the VIP and guide it into the slot. (See Figure 10.) Avoid touching the card or any connector pins.

Caution To prevent ESD damage, handle interface processors by the handles and carrier edges only.

Note The processor modules are oriented horizontally in the Cisco 7010 and Cisco 7505, and vertically in the Cisco 7000, the Cisco 7507, and the Cisco 7513.

Step 3   Place the back of the VIP in the slot and align the notch on the carrier with the groove in the slot. (See Figure 9.)

Step 4   While keeping the VIP parallel to the backplane, carefully slide it into the slot until the back of the faceplate makes contact with the ejector levers, then stop. (See Figure 9b.)

Caution Always use the ejector levers when installing or removing processor modules. A module that is partially seated in the backplane will cause the system to hang and subsequently crash, and shoving or slamming the interface processor into the slot can damage the backplane pins and board.

Step 5   Using your thumbs, simultaneously push both ejector levers inward until the VIP is pushed entirely into its slot. (See Figure 9c.)

Step 6   To ensure that EMI shielding is properly maintained for the chassis, immediately tighten both of the captive installation screws.

Checking the Installation and Verifying VIP Status

You can use the configure command to configure a VIP interface. To use the configure command, enter the privileged level of the EXEC command interpreter with the enable command. The system will prompt you for a password if one has been set.

The system prompt for the privileged level ends with a pound sign (#) instead of an angle bracket (>). At the console terminal, enter the privileged level as follows:


Step 1   At the user-level EXEC prompt, enter the enable command. The EXEC prompts you for a privileged-level password, as follows:

Router> enable Password:

Step 2   Enter the password (the password is case sensitive). For security purposes, the password is not displayed on your console.

Step 3   When you enter the correct password and press Return, the system displays the privileged-mode system prompt (#) as follows:

Router#

Checking the VIP Installation

After you install the VIP and connect cables (using connection procedures in the respective port adapter subsections), verify the installation by observing the LED states and the console display. When the system has reinitialized all interfaces, the enabled LED on the VIP and on all interface processors should go on. On the VIP-FE-TX, one or the other of the MII and RJ-45 LEDs should be on, depending on your connection, and the link LED should be on if the VIP is receiving a carrier signal from the network.

The console screen will also display a message as the system discovers each interface during its reinitialization.

When you remove and replace interface processors, the system provides status messages on the console screen. The messages are for information only.


Note Fast Ethernet interfaces are used in the following examples.

The following sample display shows the events logged by the system as a Fast Ethernet-equipped VIP was removed from slot 2; the system then reinitialized the remaining interface processors and marked as down the Fast Ethernet interfaces on the VIP that was removed from slot 2. When the VIP is reinserted, the system automatically brings up the interfaces that were up when the VIP was removed.

Router# %OIR-6-REMCARD: Card removed from slot 2, interfaces disabled %LINK-5-CHANGED: Interface FastEthernet2/0/0, changed state to administratively down Router# %OIR-6-INSCARD: Card inserted in slot 2, interfaces administratively shut down %LINK-5-CHANGED: Interface FastEthernet2/0/0, changed state to up
Note When a new VIP is inserted or when a VIP is moved to a new slot, the system recognizes the new interfaces, but leaves them in a shutdown state until you configure them and change their state to up with the configure command.

The following example display shows the events logged by the system as a new VIP-FE-TX is inserted in slot 3.

Router# %OIR-6-INSCARD: Card inserted in slot 3, interfaces administratively shut down %LINK-5-CHANGED: Interface FastEthernet3/0/0, changed state to administratively down

Verify that the VIP is installed correctly as follows:


Step 1   While the system reinitializes each interface, observe the console display messages and verify that the system discovers the VIP as follows:

Step 2   When the reinitialization is complete, verify that the enabled LED on each port adapter goes on and remains on. If it does, proceed to step 5. If it does not, proceed to the next step.

Step 3   If the enabled LED on a port adapter fails to go on, suspect that the VIP board connector is not fully seated in the backplane. Loosen the captive installation screws, then firmly push both ejector levers into place until they are approximately in the same orientation as the VIP faceplate. Tighten the captive installation screws. After the system reinitializes the interfaces, the enabled LED on the port adapter should go on. If it does, proceed to step 5. If it does not, proceed to step 4.

Step 4   If the enabled LED still fails to go on, remove the VIP and try installing it in another available interface processor slot.

Step 5   If the VIP is new and not a replacement, you have to configure the new interfaces. Proceed to the appropriate configuration section for your port adapter. (This does not have to be done immediately, but new interfaces will not be available until you configure them.)

Step 6   If the VIP is a replacement, use the show interfaces type slot/port adapter/port or show controllers cbus command to verify the status of the interfaces. (Refer to the section "Verifying VIP Status Using show Commands" on page 22.)

If you replaced a VIP with a new VIP with a greater number of ports (for example, if you replaced a one-port VIP with a two-port VIP), the system will recognize the first interface, but will not recognize the additional interface. The new interface will remain in the shutdown state until you configure it.

Step 7   When the interfaces are up, check the activity of each interface by observing the status LEDs, which are described in the appropriate LED section of this document for your port adapter type.

Step 8   In general, if an interface's LED fails to go on and a cable is connected to the port, check the cable connection and make certain it is properly seated in the connector.

If an error message is displayed on the console terminal, refer to the System Error Messages publication for error message definitions. If you experience other problems that you are unable to solve, contact a service representative for assistance.

This completes the VIP installation. If you installed a new VIP or if you installed a replacement VIP with an additional port, you must now configure the new interface as described in the following section.

Verifying VIP Status Using show Commands

The following procedure describes how to use the show commands to verify that the new interfaces are configured correctly:


Step 1   Use the show version or show hardware commands to display the system hardware configuration. Ensure that the list includes the type of interfaces you just installed (Fast Ethernet, Ethernet, Token Ring, serial, and so forth).

Step 2   Display all of the current interface processors and their interfaces with the show controllers cbus command. Verify that the new VIP appears in the correct slot.

Step 3   Specify one of the new VIP interfaces with the show interfaces type slot/port adapter/port command and verify that the first line of the display specifies the interface with the correct slot number. Also verify that the interface and line protocol are in the correct state: up or down.

Step 4   Display the protocols configured for the entire system and specific interfaces with the command show protocols. If necessary, return to Configuration mode to add or remove protocol routing on the system or specific interfaces.

Step 5   Display the entire system configuration file with the show configuration command. Verify that the configuration is accurate for the system and each interface.

If the interface is down and you configured it as up, or if the displays indicate that the hardware is not functioning properly, ensure that the network interface is properly connected and terminated. If you still have problems bringing the interface up, contact a service representative for assistance.

The show controllers cbus command displays the internal status of each interface processor, including the slot location, the card hardware version, and the currently-running microcode version. It also lists each interface (port) on each interface processor including the logical interface number, interface type, physical (slot/port adapter/port) address, and hardware (station address) of each interface. The following example shows a VIP, with Fast Ethernet interfaces, installed in interface processor slot 3:

Router# show controller cbus (display text omitted) slot3: VIP, hw 2.1, sw 200.09, ccb 5800FF70, cmdq 480000A0, vps 8192 software loaded from system FLASH ROM version 255.255, VPLD version 20.0 FastEthernet3/0/0, addr 0000.0ca5.2380 (bia 0000.0ca5.2380) gfreeq 48000140, lfreeq 48000238 (1536 bytes), throttled 0 rxlo 4, rxhi 123, rxcurr 16, maxrxcurr 16 txq 48000240, txacc 480000EA (value 77), txlimit 77      (display text omitted)

The show startup-config command displays the contents of the system configuration file stored in NVRAM. This file should reflect all new configuration changes you made and wrote to memory with the show running-config command. (A Fast Ethernet interface is used in this example.)

Router# show startup-config Using 1652 out of 130048 bytes version 11.1(1) ! hostname Router ! enable-password hello ! microcode VIP flash VIP11-0 microcode reload !

The show protocols command displays the global (system-wide) and interface-specific status of any configured Level 3 protocol.

Router# show protocols Global values: Internet Protocol routing is enabled FastEthernet3/0/0 is up, line protocol is up

Upgrading VIP Microcode

The Cisco 7000 series and the Cisco 7500 series support downloadable microcode, which enables you to upgrade microcode versions without having to physically replace the microcode Flash memory device on the board. You can download new microcode versions and store multiple versions in Flash memory, and you can boot from them just as you can with the system software images. System software upgrades may also contain upgraded microcode images, which will load automatically when the new software image is loaded (unless the configuration states otherwise).


Note Software and interface processor microcode images are carefully optimized and bundled to work together. Overriding the bundle can result in system incompatibilities. We recommend that you use the microcode included in the software bundle.

You can download microcode to Flash memory by copying the TFTP image of a microcode version to Flash memory. When the microcode image is stored in Flash memory you can use the microcode reload command to manually load the new microcode file, and the configure command to instruct the system to load the new image automatically at each system boot.

In order to compare the size of the microcode image and the amount of Flash memory available, you must know the size of the new microcode image. The image size is specified in the README file that is included on the floppy disk with the new image.


Note Note the size of the new image before proceeding to ensure that you have sufficient available Flash memory for the new image.
Caution Before you copy a file to system Flash memory, be sure there is ample space available in Flash memory. Compare the size of the file you want to copy to the amount of available Flash memory shown. If the space available is less than the space required by the file you want to copy, the copy process will continue, but the entire file will not be copied into Flash memory.

Follow these steps to download (copy) a microcode version from a TFTP server to Flash memory.


Step 1   To display the total amount of Flash memory present, its location, any files that currently exist in Flash memory and their size, and the amount of Flash memory remaining, use the show flash command. Following is an example of the output that is displayed:

Router# show flash -#- ED --type-- --crc--- -seek-- nlen -length- -----date/time------ name 1 .. FFFFFFFF B4A18E0B 3F6494 30 4023316 Jun 26 1994 19:44:29 image/file/1 2 .. FFFFFFFF 8075AA5D 4118B4 23 111518 Jun 29 1994 11:05:57 image/file/2 12044568 bytes available (8533736 bytes used)

Step 2   Compare the amount of available Flash memory (last line in the preceding example) to the size of the new microcode image on the floppy disk. If you attempt to copy in a new image, and the size of the new image exceeds the available space in Flash, only part of the new image will be copied, and the following error message will be displayed:

buffer overflow - xxxx/xxxx

where xxxx/xxxx is the number of bytes read in/number of bytes available.

Step 3   After you verify that there is sufficient space available in Flash memory for the new image, use the command copy tftp:filename [ flash | slot0 | slot1 ]:filename to copy an image to Flash memory. (tftp:filename is the file's source, and [ flash | slot0 | slot1 ]:filename is the destination in onboard Flash memory or on either of the Flash memory cards.)

An example of the copy tftp:filename command follows:

Router# copy tftp:vip11-1 slot0:vip11-1 20575008 bytes available on device slot0, proceed? [confirm] Address or name of remote host [1.1.1.1]? Loading new.image from 1.1.1.1 (via Ethernet1/0): !!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!![OK - 7799951/15599616 bytes] CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC Router#

Step 4   Use the show flash command to verify that the microcode has been copied to Flash. The output should display the filename of the image you copied to Flash (vip11-1 in the following example):

Router# show flash -#- ED --type-- --crc--- -seek-- nlen -length- -----date/time------ name 1 .. FFFFFFFF B4A18E0B 3F6494 30 4023316 Jun 26 1994 19:44:29 image/file/1 2 .. FFFFFFFF 8075AA5D 4118B4 23 111518 Jun 29 1994 11:05:57 image/file/2 3 .. FFFFFFFF EEA1FEEB 8436E8 22 4398516  Oct 10 1995 19:35:25 vip11-1 7646052 bytes available (16179788 bytes used)

Step 5   To ensure that the new microcode is used when you reboot the system, add the appropriate commands to the configuration file. To modify the configuration file, enter the configure terminal command, as follows:

Router# config t Enter configuration commands, one per line. End with CNTL/Z. Router(config)#

Step 6   Specify that you are changing the microcode for the VIP (microcode vip), and that it will load from Flash memory (flash). Then add the filename of the new microcode image to be loaded from Flash:

Router(config)# microcode vip flash slot0:vip11-1

Step 7   To save the configuration file, press Ctrl-Z.

Step 8   Copy the new configuration to nonvolatile random-access memory (NVRAM):

Router# copy running-config startup-config

The microcode reload command is automatically added to your running configuration. The new VIP microcode image will load automatically the next time the system boots or reinitializes.

Step 9   To load the new microcode immediately, you can issue the microcode reload configuration command (you must be in Configuration mode to enter this command):

Router# config t Enter configuration commands, one per line. End with CNTL/Z. Router(config)# microcode reload

Immediately after you enter the microcode reload command and press Return, the system reloads all microcode. Configuration mode remains enabled; after the reload is complete, press Ctrl-Z to exit from Configuration mode and return to the system prompt.

Step 10   To verify that the VIP is using the correct microcode, issue the show startup-config or show controllers cbus command, which indicates the currently loaded and running microcode version for each interface processor and the SP or SSP in the Cisco 7000 series routers.

Router# show controllers cbus

This completes the procedure for downloading microcode to Flash memory.

Upgrading and Replacing DRAM SIMMs

VIPs are shipped with 8 MB of DRAM as the default memory configuration. Depending on memory requirements, you might need to upgrade the amount of DRAM by replacing the DRAM SIMMs on the VIP. You also might need to replace a single SIMM in the case of a diagnosed DRAM SIMM failure.


Note DRAM SIMMs should be upgraded or replaced in the field by a Cisco-certified maintenance provider. Both DRAM SIMMs are replaced for all upgrades.
Caution SIMMs are sensitive components that are susceptible to ESD damage. Handle SIMMs by the edges only; avoid touching the memory modules, pins, or traces (the metal fingers along the connector edge of the SIMM). (See Figure 11.)

Figure 11: Handling a DRAM SIMM—Example Only


Following is the procedure for replacing or upgrading DRAM SIMMs.


Step 1   Attach an ESD-preventive wrist strap between you and an unpainted chassis or VIP surface.

Step 2   Disconnect all cables from the VIP and remove it from the chassis using the procedure in the section "Removing a VIP" on page 17.

Step 3   Place the VIP on a flat surface (preferably an antistatic mat or foam), and turn it so the face plate is away from you and the connector edge is toward you. (approximately opposite of the orientation shown in Figure 12).

Step 4   Locate the DRAM SIMMs in U1 and U2. (See Figure 12.)


Figure 12: Orientation of DRAM SIMMs (U1 and U2) on VIP Motherboard


Step 5   Remove a SIMM by pulling outward on the connectors to unlatch it, as shown in the enlargement in Figure 13. Be careful not to break the holders on the SIMM connector.


Figure 13: Removing and Replacing DRAM SIMMs


Step 6   Using the SIMM orientation shown in Figure 13, position the new SIMM so that the polarization notch is located at the right end of the SIMM socket.

Step 7   Insert the new SIMM by sliding the end with the metal fingers into the SIMM connector socket at approximately a 45-degree angle to the system card. Gently rock the SIMM back into place until the latch on either side snaps into place. (See Figure 13.)

Caution Do not use excessive force, or the connector could break. To prevent damage, do not push on the center of the SIMMs. Handle each SIMM with care.

Step 8   As required, repeat Steps 5 through 7 for the second SIMM.

Step 9   Reinstall the VIP in the chassis using the procedure in the section "Installing a VIP" on
page 19.

If error messages relating to memory are displayed once power to the chassis is turned back on, or the VIP card is installed in a chassis that is already on, repeat Steps 1 through 8, taking care to firmly reseat each SIMM in its socket.

This completes the procedure for upgrading or replacing DRAM SIMMs on your VIP.

FE-TX Port Adapter Functions

The following sections discuss the FE-TX port adapter, which is shown in Figure 14.


Figure 14: FE-TX Port Adapter, Faceplate View


Fast Ethernet Overview

The VIP configured with one FE-TX port adapter provides a 100-Mbps, 100BASE-T, Fast Ethernet interface. Each 100BASE-T port on the FE-TX port adapter has an RJ-45 connector to attach to Category 5 unshielded twisted-pair (UTP) for 100BASE-TX, and a MII connector that permits connection through external transceivers to multimode fiber for 100BASE-FX, or to Category 3, 4, and 5 UTP or shielded twisted-pair (STP) for 100BASE-T4 physical media.

Both full-duplex and half-duplex operation are supported.The term Ethernet is commonly used for all carrier sense multiple access/collision detection (CSMA/CD), local-area networks (LANs) that generally conform to Ethernet specifications, including IEEE 802.3u.


Note 100BASE-TX is intended for Environment A and 100BASE-FX is intended for Environment B.

IEEE 802.3u is well suited to applications where a local communication medium must carry sporadic, occasionally heavy traffic at high peak data rates. Stations on a CSMA/CD LAN can access the network at any time. Before sending data, the station listens to the network to see if it is already in use. If it is, the station waits until the network is not in use, then transmits; this is half-duplex operation. A collision occurs when two stations listen for network traffic, hear none, and transmit very close to simultaneously. When this happens, both transmissions are damaged, and the stations must retransmit. The stations detect the collision and use backoff algorithms to determine when they should retransmit.

Both Ethernet and IEEE 802.3u are broadcast networks, which means that all stations see all transmissions. Each station must examine received frames to determine whether it is the intended destination and, if it is, pass the frame to a higher protocol layer for processing.

IEEE 802.3u specifies the following different physical layers for 100BASE-T:

Each physical layer protocol has a name that summarizes it characteristics in the format speed/signaling method/segment length where speed is the LAN speed in megabits per second (Mbps), signaling method is the signaling method used (either baseband or broadband), and segment length is typically the maximum length between stations in hundreds of meters. Therefore, 100BASE-T specifies a 100-Mbps, baseband LAN with maximum network segments of 100 meters (or 400 meters for 100BASE-FX).

FE-TX Port Adapter Description and Fast Ethernet Specifications

The FE-TX port adapter is available in the following VIP configurations: FE-TX/blank, FE-TX/4E, or FE-TX/FE-TX. Figure 15 shows the VIP-FE-TX. The FE-TX port adapter has a handle attached, but this handle is not shown to allow a full view of the detail on the port adapter's faceplate.


Figure 15: VIP with One FE-TX Port Adapter Installed (Horizontal Orientation Shown)


Caution To prevent system problems, do not remove port adapters from the VIP motherboard, or attempt to install other port adapters on the VIP motherboard.

Table 1 lists the cabling specifications for 100-Mbps Fast Ethernet transmission over UTP and STP cables. Table 2 summarizes IEEE 802.3u 100BASE-T physical characteristics.

FE-TX Port Adapter LEDs

The FE-TX port adapter contains the enabled LED, standard on all port adapters, and a bank of three status LEDs for the ports. After system initialization, the enabled LED goes on to indicate that the FE-TX port adapter has been enabled for operation. (The LEDs are shown in Figure 16.) The following conditions must be met before the enabled LED goes on:

If any of these conditions is not met, or if the initialization fails for other reasons, the enabled LED does not go on.

The bank of three status LEDs indicates the following:

Either the MII LED or the RJ-45 LED should be on at any one time; never both.


Figure 16:
LEDs on the FE-TX Port Adapter (Horizontal Orientation Shown)



Note The VIP is oriented horizontally in the Cisco 7010 and Cisco 7505, and vertically in the Cisco 7000, the Cisco 7507, and the Cisco 7513.

FE-TX Port Adapter Receptacles, Cables, and Pinouts

The two interface receptacles on the FE-TX port adapter are a single MII, 40-pin, D-shell type, and a single RJ-45. You can use either one or the other. Only one receptacle can be used at one time. Each connection supports IEEE 802.3u interfaces compliant with the 100BASE-X and 100BASE-T standards. The RJ-45 connection does not require an external transceiver. The MII connection requires an external physical sublayer (PHY) and an external transceiver.

Figure 17 shows the RJ-45 connectors. Table 3 lists the pinouts and signals for the FE-TX RJ-45 connectors.


Figure 17: FE-TX RJ-45 Connections, Plug and Receptacle


Warning The ports labeled "Ethernet," "10BaseT," "Token Ring," "Console," and "AUX" are safety extra-low voltage (SELV) circuits. SELV circuits should only be connected to other SELV circuits. Because the BRI circuits are treated like telephone-network voltage, avoid connecting the SELV circuit to the telephone network voltage (TNV) circuits. (For translated versions of this warning, refer to the section "SELV Circuit Warning Translations" on page page 42.)

Note Referring to the RJ-45 pinout in
Table 3, proper common-mode line terminations should be used for the unused Category 5, UTP cable pairs 4/5 and 7/8. Common-mode termination reduces the contributions to electromagnetic interference (EMI) and susceptibility to common-mode sources. Wire pairs 4/5 and 7/8 are actively terminated in the RJ-45, 100BASE-TX port circuitry in the FE-TX port adapter.

Depending on your RJ-45 interface cabling requirements, use the pinouts in Figure 18 and Figure 19.


Figure 18: Straight-Through Cable Pinout, FE-TX RJ-45 Connection to a Hub or Repeater



Figure 19:
Crossover Cable Pinout, FE-TX RJ-45 Connections Between Hubs and Repeaters


Depending on the type of media you use between the MII connection on the port adapter and your switch or hub, the network side of your 100BASE-T transceiver should be appropriately equipped with ST-type connectors (for optical fiber), BNC connectors, and so forth. Figure 20 shows the pin orientation of the female MII connector on the port adapter. The port adapters are field-replacable units (FRUs).

The MII receptacle uses 2-56 screw-type locks, called jackscrews (shown in Figure 20), to secure the cable or transceiver to the MII port. MII cables and transceivers have knurled thumbscrews (screws you can tighten with your fingers) that you fasten to the jackscrews on the FE-TX port adapter's MII connector. Use the jackscrews to provide strain relief for your MII cable. (The RJ-45 modular plug has strain relief functionality incorporated into the design of its standard plastic connector.) Figure 20 shows the MII female connector.

Attaching FE-TX Port Adapter Interface Cables

On a single 100BASE-T port adapter, you can use either the RJ-45 connection or the MII connection. If you have two FE-TX, 100BASE-T port adapters on your VIP, you can use the RJ-45 connection on one and the MII connection on the other.


Note RJ-45 and MII cables are not available from Cisco Systems; they are available from outside commercial cable vendors.

Connect RJ-45 and MII cables as follows:


Step 1   If you have RJ-45 connections, attach the Category 5 UTP cable directly to the RJ-45 port on the FE-TX port adapter. (See Figure 21.)

If you have MII connections, attach an MII cable directly to the MII port on the FE-TX port adapter or attach a 100BASE-T transceiver, with the media appropriate to your application, to the MII port on the FE-TX port adapter. (See Figure 21.)

The FE-TX port adapter is an end station device and not a repeater. You must connect the FE-TX port adapter to a repeater or hub.


Note On the VIP-FE-TX, the FE-TX port adapter can have either an MII attachment or an RJ-45 attachment, but not both simultaneously. The MII and RJ-45 receptacles represent two physical connection options, for one Fast Ethernet interface. The FE-TX port adapter has a handle attached, but this handle is not shown to allow a full view of the detail on the port adapter's faceplate.

Figure 21: Connecting FE-TX MII or RJ-45 Cables (Horizontal Orientation—Shown without Handles)


Step 2   Attach the ferrite bead to the RJ-45 cable (at either end), as shown in Figure 22.

Caution The ferrite bead prevents electromagnetic interference (EMI) from affecting the FE-TX-equipped system and is a required component for proper system operation.

Figure 22: Attaching the Ferrite Bead around the RJ-45 Cable


Caution To prevent problems on your FE-TX port adapter and network, do not simultaneously connect RJ-45 and MII cables to one 100BASE-T port adapter. On a single 100BASE-T port adapter, only one network connection can be used at one time. Only connect cables that comply with EIA/TIA-568 standards. (Refer to Table 1 and Table 2 on page 32 for cable recommendations and specifications.)

Step 3   Attach the network end of your RJ-45 or MII cable to your 100BASE-T transceiver, switch, hub, repeater, DTE, or other external 100BASE-T equipment.

This completes the FE-TX installation. Proceed to the section "Checking the VIP Installation."

Configuring the FE-TX Interface

If you installed a new FE-TX interface or if you want to change the configuration of an existing interface, you must enter Configuration mode, using the configuration command. If you replaced an interface that was previously configured, the system will recognize the new interface and bring it up in its existing configuration.

After you verify that the new FE-TX is installed correctly (the enabled LED goes on), use the privileged-level configure command to configure the new interfaces. Be prepared with the information you will need, such as the following:


Note For a summary of the configuration options available and instructions for configuring the FE-TX interfaces on the VIP, refer to the publications listed in the section "
If You Need More Information" on page 2.

Note The configure command requires privileged-level access to the EXEC command interpreter, which usually requires a password. Contact your system administrator, if necessary, to obtain EXEC-level access.

Selecting Chassis Slot, Port Adapter, and Fast Ethernet Interface Port Numbers

The following section describes how to identify chassis slot, port adapter, and Fast Ethernet interface port numbers.


Note Although the processor slots in the seven-slot Cisco 7000 and 13-slot Cisco 7513 are vertically oriented and those in the five-slot Cisco 7010 and Cisco 7505 are horizontally oriented, all models use the same method for slot and port numbering. (Refer to
Figure 2, Figure 3, Figure 4, Figure 5, or Figure 6 for interface processor slot orientation in your chassis.)

In the router, physical port addresses specify the actual physical location of each interface port on the router interface processor end. (See Figure 23.) This address is composed of a three-part number in the format chassis slot number/port adapter number/interface port number.

The first number identifies the chassis slot in which the VIP is installed (as shown in the example system in Figure 23). The second number identifies the physical port adapter number on the VIP, and is port adapter slot 0. The interface ports on the FE-TX port adapter is always numbered as interface 0.


Note If you remove the VIP from slot 3 and install it in slot 2, the address of this port becomes 2/0/0.

Figure 23: Fast Ethernet Interface Port Number Example (Cisco 7505 Shown)


Interface ports on the VIP maintain the same address regardless of whether other interface processors are installed or removed. However, when you move a VIP to a different slot, the first number in the address changes to reflect the new slot number.

Figure 23 shows some of the slot port adapter and interface ports of a sample Cisco 7505 system. For example, on a VIP-FE-TX in slot 3, the address of the Fast Ethernet port adapter is 3/0/0 (chassis slot 3, port adapter slot 0, and interface port 0). The individual port adapter number is always 0. The individual interface port numbers always begin with 0. For example, the FE-TX port adapter in the first port adapter slot in chassis slot 3 would 3/0/0. The number of additional ports depends on the number of ports on a port adapter.

You can identify interface ports by physically checking the slot/port adapter/interface port location on the back of the router or by using software commands to display information about a specific interface or all interfaces in the router.

To display information about a specific interface, use the show interfaces command with the interface type and port address in the format show interfaces [type slot/port adapter/port].

Following is an example of how the show interfaces command displays status information (including the physical slot and port address) for the interface you specify. In this example, most of the status information for each interface is omitted, and a Fast Ethernet interface in slot 3 is used.

Router# sh int fa 3/0/0 FastEthernet3/0/0 is administratively down, line protocol is down Hardware is cyBus FastEthernet Interface, address is 0000.0ca5.2380 (bia 0000) MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec, rely 255/255, load 1/255 Encapsulation ARPA, loopback not set, keepalive set (10 sec), hdx, 100BaseTX (display text omitted)

The Fast Ethernet interface port adapter is numbered as port adapter 0. The MII and RJ-45 ports on a port adapter each have the same port number because only one of them can be used at one time. The single Fast Ethernet port on the FE-TX port adapter is interface 0.

With the show interfaces type slot/port adapter/port command, use arguments such as the interface type (fastethernet, and so forth) and the port number (slot/port) to display information about a specific interface only. The following example of the show interfaces fastethernet command shows information specific to the Fast Ethernet interface on the first FE-TX port adapter in slot 3:

Router# show interfaces fastethernet 3/0/0 FastEthernet3/0/0 is administratively down, line protocol is down Hardware is cyBus FastEthernet Interface, address is 0000.0ca5.2380 (bia 0000) MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec, rely 255/255, load 1/255 Encapsulation ARPA, loopback not set, keepalive set (10 sec), hdx, 100BaseTX ARP type: ARPA, ARP Timeout 4:00:00 Last input 3:08:43, output 3:08:42, output hang never Last clearing of "show interface" counters 2:58:36 Output queue 0/40, 0 drops; input queue 0/75, 0 drops 5 minute input rate 0 bits/sec, 0 packets/sec 5 minute output rate 0 bits/sec, 0 packets/sec 0 packets input, 0 bytes, 0 no buffer Received 0 broadcasts, 0 runts, 0 giants 0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort 0 watchdog, 0 multicast 0 input packets with dribble condition detected 0 packets output, 0 bytes, 0 underruns 0 output errors, 0 collisions, 0 interface resets, 0 restarts 0 babbles, 0 late collision, 0 deferred 0 lost carrier, 0 no carrier 0 output buffer failures, 0 output buffers swapped out

Configuring the FE-TX Port Adapters—Descriptions and Examples

Following are descriptions and examples of the commands for configuring the FE-TX interface 3/0/0 (slot 3, port adapter 0, Fast Ethernet interface port 0). Descriptions are limited to fields that are relevant for establishing and verifying the configuration. After configuring the new FE-TX interface, use show commands to display the status of the new interface or all interfaces, or to verify changes you have made.

Depending on the requirements for your system configuration and the protocols you plan to route on the interface, you might also need to enter other configuration subcommands. For complete descriptions of configuration subcommands and the configuration options available for Fast Ethernet interfaces, refer to the publications listed in the section "If You Need More Information" on page 2.

FE-TX half-duplex operation is the default. To change to full-duplex operation, use the following series of commands:

Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)# Router(config)# interface fastethernet 3/0/0 Router(config-if)# full-duplex Router(config-if)# ^z

Using the show interfaces fastethernet command, you can see that the 3/0/0 Fast Ethernet interface is now configured for full-duplex operation, as follows:

Router# sh int fa 3/0/0 FastEthernet 3/0/0 is administratively up, line protocol is up   (display text omitted) Encapsulation ARPA, loopback not set, keepalive not set, fdx, 100BaseTX

To return the interface to half-duplex operation, use the no full-duplex configuration command, as follows:

Router# config t Enter configuration commands, one per line. End with CNTL/Z. Router(config)# int fa 3/0/0 Router(config-if)# no full-duplex Router(config-if)# ^Z Router#

Using the show interfaces fastethernet command, you can see that the 3/0/0 Fast Ethernet interface is now configured for half-duplex operation, as follows:

Router# sh int fa 3/0/0 FastEthernet3/0/0 is administratively up, line protocol is up   (display text omitted) Encapsulation ARPA, loopback not set, keepalive not set, hdx, 100BaseTX (display text omitted)

The RJ-45 connection is the default. To change to an MII connection and then verify it, use the following series of commands, including the media-type configuration command:

Router# config t Enter configuration commands, one per line. End with CNTL/Z. Router(config)# int fa 3/0/0 Router(config-if)# media-type mii Router(config-if)# ^Z Router# sh int fa 3/0/0 FastEthernet3/0/0 is administratively up, line protocol is up   (display text omitted) Encapsulation ARPA, loopback not set, keepalive not set, hdx, MII   (display text omitted)

Use the media-type 100BaseTX configuration command to return the interface to its default state for RJ-45 connections.

The show version (or show hardware) command displays the configuration of the system hardware (the number of each interface processor type installed), the software version, the names and sources of configuration files, and the boot images. Following is an example of the show version command used with a Cisco 7500 series system:

SELV Circuit Warning Translations

Warning 
The ports labeled "Ethernet," "10BaseT," "Token Ring," "Console," and "AUX" are safety extra-low voltage (SELV) circuits. SELV circuits should only be connected to other SELV circuits. Because the BRI circuits are treated like telephone-network voltage, avoid connecting the SELV circuit to the telephone network voltage (TNV) circuits.

Waarschuwing   De poorten die "Ethernet", "10BaseT", "Token Ring", "Console" en "AUX" zijn gelabeld, zijn veiligheidscircuits met extra lage spanning (genaamd SELV = Safety Extra-Low Voltage). SELV-circuits mogen alleen met andere SELV-circuits verbonden worden. Omdat de BRI-circuits op dezelfde manier als telefoonnetwerkspanning behandeld worden, mag u het SELV-circuit niet verbinden met de telefoonnetwerkspanning (TNV) circuits.

Varoitus   Portit, joissa on nimet "Ethernet", "10BaseT", "Token Ring", "Console" ja "AUX", ovat erityisen pienen jännityksen omaavia turvallisuuspiirejä (SELV-piirejä). Tällaiset SELV-piirit tulee yhdistää ainoastaan muihin SELV-piireihin. Koska perusluokan liitäntöjen (Basic Rate Interface- eli BRI-liitännät) jännite vastaa puhelinverkoston jännitettä, vältä SELV-piirin yhdistämistä puhelinverkoston jännitepiireihin (TNV-piireihin).

Attention   Les ports étiquetés « Ethernet », « 10BaseT », « Token Ring », « Console » et « AUX » sont des circuits de sécurité basse tension (Safety Extra-Low Voltage ou SELV). Les circuits SELV ne doivent être interconnectés qu'avec d'autres circuits SELV. Comme les circuits BRI sont considérés comme des sources de tension de réseau téléphonique, éviter de connecter un circuit SELV à un circuit de tension de réseau téléphonique (telephone network voltage ou TNV).

Warnung   Die mit "Ethernet", "10BaseT", "Token Ring", "Console" und "AUX" beschrifteten Buchsen sind Sicherheitskreise mit Sicherheitskleinspannung (Safety Extra-Low Voltage, SELV). SELV-Kreise sollten ausschließlich an andere SELV-Kreise angeschlossen werden. Da die BRI-Kreise wie Telefonnetzspannungen behandelt werden, ist der SELV-Kreis nicht an Telefonnetzspannungskreise (TNV) anzuschließen.

Avvertenza   Le porte contrassegnate da "Ethernet", "10BaseT", "TokenRing", "Console" e "AUX" sono circuiti di sicurezza con tensione molto bassa (SELV). I circuiti SELV devono essere collegati solo ad altri circuiti SELV. Dato che i circuiti BRI vengono trattati come tensioni di rete telefonica, evitare di collegare il circuito SELV ai circuiti in cui è presente le tensione di rete telefonica (TNV).

Advarsel   Utgangene merket "Ethernet", "10BaseT", "Token Ring", "Console" og "AUX" er lavspentkretser (SELV) for ekstra sikkerhet. SELV-kretser skal kun kobles til andre SELV-kretser. Fordi BRI-kretsene håndteres som telenettspenning, unngå å koble SELV-kretsen til kretser for telenettspenning (TNV).

Aviso   As portas "Ethernet", "10BaseT", "Token Ring", "Console", and "AUX" são circuitos de segurança de baixa tensão (SELV). Estes circuitos deverão ser apenas ligados a outros circuitos SELV. Devido ao facto de os circuitos BRI (Interface de Ritmo Básico) serem tratados como sendo de tensão equivalente à da rede telefónica, evite ligar o circuito SELV aos circuitos TNV (tensão de rede telefónica).

¡Advertencia!   Los puertos "Ethernet", "10BaseT", "Token Ring", "Console" y "AUX" son circuitos de muy baja señal que garantizan ausencia de peligro (Safety Extra-Low Voltage = SELV). Estos circuitos SELV deben ser conectados exclusivamente con otros también de tipo SELV. Puesto que los circuitos tipo BRI se comportan como aquéllos con voltajes de red telefónica, debe evitarse conectar circuitos SELV con circuitos de voltaje de red telefónica (TNV).

Varning!   De portar som är märkta "Ethernet", "10BaseT", "Token Ring", "Console" och "AUX" är SELV-kretsar, d.v.s. skyddskretsar med extra låg spänning (SELV: Safety Extra-Low Voltage = skyddsklenspänning). SELV-kretsar får endast anslutas till andra SELV-kretsar. Eftersom BRI-kretsar behandlas liksom telefonnätsspänning bör SELV-kretsen inte anslutas till telefonnätsspänningskretsar (TNV-kretsar).
