Product Number VIP-FE-TX/4E(=)
This configuration note is a standalone publication that provides instructions for installing, configuring, and maintaining the Fast Ethernet/Ethernet Versatile Interface Processor (VIP-FE-TX/4E) in your Cisco 7000 series and Cisco 7500 series routers.
The VIP-FE-TX/4E 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.
Included are steps for VIP-FE-TX/4E hardware installation, and basic VIP configuration steps and examples for configuring the individual interfaces on a new VIP.
This publication has two main sections:
You need only refer to the information that is specific to your FE-TX and 4E port adapter or that applies to specific VIP functionality. A table of contents is included on page 2 so you can more easily find what you need.
This configuration note includes the following sections:
The Cisco Internetwork Operating System (Cisco IOS) software running the router contains extensive features and functionality. The effective use of many of many of these features is easier if you have more information at hand.
For additional information on configuring the Cisco 7000 series or Cisco 7500 series routers, the following documentation resources are available to you:
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.
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/4E. 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 or Cisco 7500 series router.
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.
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 "SELV Circuit Warning Translations" at the end of this publication.
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.
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.
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.
Figure 4, Figure 5, and Figure 6 show the rear of the Cisco 7500 series routers: the five-slot Cisco 7505, the seven-slot Cisco 7507, and the thirteen-slot Cisco 7513, respectively.
In the Cisco 7505, one slot (4) is reserved for the Route Switch Processor (RSP1), which contains the system processor and performs packet switching functions. Slots 0 through 3 are for interface processors.
Figure 5 shows the rear of the seven-slot Cisco 7507 router. In the Cisco 7507, up to two slots (2 and 3) are reserved for the Route Switch Processor (RSP2), which contains the system processor and performs packet switching functions. Slots 0 and 1 and 4 through 6 are for interface processors.
Figure 6 shows the rear of the Cisco 7513 with two AC-input power supplies installed. Two slots (6 and 7) are reserved for the second generation Route Switch Processor (RSP2), which contains the system processor and performs packet switching functions. Slots 0 through 5 and 8 through 12 are for interface processors.
The port adapters attach to the VIP motherboard. (See Figure 7.) Each port adapter contains the physical connections for the VIP interface types to connect to your network.
Following are the VIP port adapters by interface type:
Following are the supported electrical interfaces:
 | 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. |
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 23.
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.
Following are safety guidelines that you should follow when working with any equipment that connects to electrical power or telephone wiring.
Follow these basic guidelines when working with any electrical equipment:
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. |
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 16.
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 8) 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.
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 13.
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."
| 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. |
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 8.)
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 8c).
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 9.) 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 18.
Figure 9 shows proper handling of an interface processor during installation.
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 8.)
| 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 8c) 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 9.) 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."
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 8 shows the functional details of inserting an interface processor and using the ejector levers. Figure 9 shows proper handling of an interface processor during installation.
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 9.) Avoid touching the card or any connector pins.
| Caution To prevent ESD damage, handle interface processors by the handles and carrier edges only. |
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 8.)
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 8b.)
Step 5 Using your thumbs, simultaneously push both ejector levers inward until the VIP is pushed entirely into its slot. (See Figure 8c.)
Step 6 To ensure that EMI shielding is properly maintained for the chassis, immediately tighten both of the captive installation screws.
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#
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.
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
The following example display shows the events logged by the system as a new VIP 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 21.)
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 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.
The following procedure describes how to use the show commands to verify that the new interfaces are configured correctly:
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 the 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

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.
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.
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

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

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
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.
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.
| 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 10.) |
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 16.
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 11).
Step 4 Locate the DRAM SIMMs in U1 and U2. (See Figure 11.)
Step 5 Remove a SIMM by pulling outward on the connectors to unlatch it, as shown in the enlargement in Figure 12. Be careful not to break the holders on the SIMM connector.
Step 6 Using the SIMM orientation shown in Figure 12, 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 12.)
| 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 18.
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.
The following sections discuss the port adapters used with the VIP:
The following sections discuss the FE-TX port adapter, which is shown in Figure 13.
The VIP configured with two FE-TX port adapters provides up to two 100-Mbps, 100BASE-T, Fast Ethernet interfaces. 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.
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.
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).
IEEE 802.3u specifies the following different physical layers for 100BASE-T:
The FE-TX port adapter is available in the following VIP configurations: FE-TX/blank, FE-TX/4E, or FE-TX/FE-TX. (For a description of the 4E port adapter, refer to the section "4E Port Adapter" on page 44.) Figure 14 shows VIP-FE-TX/4E. The FE-TX and 4E port adapters have a handle attached, but this handle is not shown to allow a full view of detail on each 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. |

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 15.) 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.
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 16 shows the RJ-45 connectors. Table 3 lists the pinouts and signals for the FE-TX RJ-45 connectors.
 | 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 57.) |

Depending on your RJ-45 interface cabling requirements, use the pinouts in Figure 17 and Figure 18.
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 19 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 19), 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 19 shows the MII female connector.
Table 4 lists the MII connector pinout and signals. MII cables are available commercially.

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 20.)
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 20.)
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.
Step 2 Attach the ferrite bead to the RJ-45 cable (at either end), as shown in Figure 21.
| Caution The ferrite bead prevents electromagnetic interference (EMI) from affecting the FE-TX-equipped system and is a required component for proper system operation. |
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."
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:
In the router, physical port addresses specify the actual physical location of each interface port on the router interface processor end. (See Figure 22.) 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 22). The second number identifies the physical port adapter number on the VIP, and is either 0 or 1. The interface ports on each FE-TX port adapter are always numbered as interface 0.
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 22 shows some of the slot port adapter and interface ports of a sample Cisco 7505 system. For example, on a FE-TX/FE-TX VIP in slot 3, the address of the first Fast Ethernet port adapter is 3/0/0 (chassis slot 3, port adapter slot 0, and interface port 0), and the address of the second Fast Ethernet port adapter is 3/1/0 (chassis slot 3, port adapter slot 1, and interface port 0).
The individual port adapter numbers are always 0 and 1. The individual interface port numbers always begin with 0. For example, the FE-TX port adapters in the first and second port adapter slots in chassis slot 3 would have the following addresses: 3/0/0 and 3/1/0. 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.

(display text omitted)
Fast Ethernet interface port adapters are numbered from 0 and 1 because VIPs support up to two 100BASE-T ports. 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.
Refer to Table 5, Table 6, Table 7, Table 8, and Table 9 for the FE-TX port numbers associated with the interface processor slots in your chassis. If you install a VIP with two FE-TX port adapters, you can configure both ports; if you install a VIP with one FE-TX port adapter, you need configure only that port.

Following are descriptions and examples of the commands for configuring the VIP FE-TX interface 3/0/0 (slot 3, port adapter 0, Fast Ethernet interface port 0). If a second Fast Ethernet interface is present, configure it the same way except that the port adapter number is port adapter 1 (3/1/0).
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.

The following sections discuss the 4E port adapter, which is shown in Figure 23.
The VIP 4E port adapter provides up to four IEEE 802.3 Ethernet 10BASE-T interfaces on the VIP. Each Ethernet 10BASE-T interface allows a maximum bandwidth of 10-Mbps, for a maximum aggregate bandwidth of 40 Mbps. All four ports run at line speed.
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 802.3. Ethernet Version 2 and IEEE 802.3 were based on, and developed shortly after, Ethernet Version 1. The slight differences between Ethernet and IEEE 802.3 are implemented in hardware, and both are supported automatically by the 4E without any hardware configuration changes. Together, Ethernet and IEEE 802.3 are the most widely used LAN protocols. They are 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 of it is already in use. If it is, the station waits until the network is not in use, then transmits. A collision occurs when two stations listen for network traffic, hear none, and transmit 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 802.3 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 802.3 specifies several different physical layers, and Ethernet defines only one. Each IEEE 802.3 physical layer protocol has a name that summarizes its characteristics in the format speed/signaling method/segment length where speed is the LAN speed in Mbps, signaling method is the signaling method used (either Baseband or Broadband), and segment length is the maximum length between stations in hundreds of meters.
The 4E port adapter is currently only available on the VIP-FE-TX/4E, which has a single Fast Ethernet (FE-TX) port adapter in port adapter slot 0, and a single Ethernet 10BASE-T (4E) port adapter in port adapter slot 1. (For a description of the FE-TX port adapter, refer to the section "FE-TX Port Adapter" on page 29.) Figure 24 shows the VIP-FE-TX/4E.
| 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. |

| 1Cisco Systems does not supply Category 5 UTP RJ-45 cables; these cables are available commercially. 2AWG = American Wire Gauge. This gauge is specified by the EIA/TIA-568 standard. |
The Ethernet specifications call the 4E device a transceiver, and it is connected to the station with a transceiver cable. The 4E port adapter is not an end station. The IEEE 802.3 specifications refer to the same type of device as a media attachment unit (MAU) and to the cable as an attachment unit interface (AUI). Only transceiver cables can connect to the 4E ports directly.
The 4E port adapter contains the enabled LED, standard on all port adapters, and a one status LED for each port. After system initialization, the enabled LED goes on to indicate that the 4E port adapter has been enabled for operation. (The LEDs are shown in Figure 25.) 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.
When an RJ-45 port is active, its link LED is on when the 4E port adapter is receiving a carrier signal from the network.
The interface connectors on the 4E port adapter are four individual RJ-45 receptacles. You can use all four simultaneously. Each connection supports IEEE 802.3 and Ethernet 10BASE-T interfaces compliant with appropriate standards. The RJ-45 connections require external transceivers.
Figure 26 shows the RJ-45 connectors. Table 12 lists the pinouts and signals for the RJ-45 connectors.
| 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 57.) |

Depending on your 4E, RJ-45 interface cabling requirements, use the pinouts in Figure 27 and Figure 28.
On a single 4E port adapter, you can use up to four RJ-45 connections.
Connect RJ-45 cables to the 4E port adapter as follows:
Step 1 Attach the Category 5 UTP cable directly to the RJ-45 port on the 4E port adapter. (See Figure 29.)
The 4E port adapter is an end station device and not a repeater. You must connect the 4E port adapter to a repeater or hub.
Step 2 Attach the ferrite bead to the RJ-45 cable (at either end), as shown in Figure 30.
| Caution The ferrite bead prevents electromagnetic interference (EMI) from affecting the 4E-equipped system and is a required component for proper system operation. |
Step 3 Attach the network end of your RJ-45 cable to your 10BASE-T hub or repeater, DTE, or other external 10BASE-T equipment.
This completes the 4E installation. Proceed to the section "Checking the VIP Installation" on page 19, then to the section "Configuring the 4E Interfaces," which follows.
After you verify that the new 4E port adapter 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:
For a summary of the configuration options available and instructions for configuring the 4E interfaces on the VIP, refer to the Router Products Configuration Guide.
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. The 4E interfaces on a VIP can both be configured at 10 Mbps, half duplex (HDX) or full duplex (FDX), for a maximum aggregate bandwidth of 40 Mbps.
The following section describes how to identify chassis slot, port adapter, and Ethernet 10BASE-T interface port numbers.
In the router, physical port addresses specify the actual physical location of each interface port on the router interface processor end. (See Figure 22.) 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 31). The second number identifies the physical port adapter number on the VIP, and is either 0 or 1. The interface ports on each 4E port adapter are always numbered in sequence as interface 0 through 3.
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 22 shows some of the slot port adapter and interface ports of a sample Cisco 7505 system. For example, on a FE-TX/4E VIP in slot 3, the address of the first Fast Ethernet port adapter is 3/0/0 (chassis slot 3, port adapter slot 0, and interface port 0—see the section "Selecting Chassis Slot, Port Adapter, and Fast Ethernet Interface Port Numbers" on page 38 for the Fast Ethernet numbering scheme), and the addresses for the Ethernet 10BASE-T interface ports on the second port adapter (which is a 4E) are 3/1/0 through 3/1/3 (chassis slot 3, port adapter slot 1, and interface ports 0 through 3).
The first port adapter slot number is always 0. The second port adapter slot number is always 1. The individual interface port numbers always begin with 0. The number of additional ports depends on the number of ports on a port adapter. For example, the four 10BaseT interface ports on a 4E port adapter in the second port adapter slot in chassis slot 3, would have the following addresses: 3/1/0, 3/1/1, 3/1/2, and 3/1/3. (See Figure 31.)
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].

Ethernet 10BASE-T interface port adapters are always numbered as port adapter 1 because VIPs currently support only one 4E port adapter with the FE-TX/4E configuration, and the 4E port adapter is always in the second port adapter slot location (port adapter slot 1). With this VIP configuration, a FE-TX port adapter is always in port adapter slot 0.
Refer to Table 13, Table 14, Table 15, Table 16, and Table 17 for the 4E port numbers associated with the interface processor slots in your chassis.

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).
