Follow these guidelines when working on equipment powered by electricity:
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It occurs when electronic printed circuit cards are improperly handled and can result in complete or intermittent failures. Always follow ESD prevention procedures when removing and replacing cards. Ensure that the chassis is electrically connected to earth ground. Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. Connect the clip to an unpainted surface of the chassis frame to safely channel unwanted ESD voltages to ground. To properly guard against ESD damage and shocks, the wrist strap and cord must operate effectively. If no wrist strap is available, ground yourself by touching the metal part of the chassis.
The MICA carrier card requires the following images:
To install the MICA modules and carrier cards, you will need the following tools and equipment which are not included:
The LEDs on the front panel of the MICA carrier card (see Figure 1) indicate the current operating condition of the 6-port MICA modules installed on the card. You can observe the LEDs, note any fault condition that the product is encountering, and then contact your system administrator or a customer service representative, if necessary. See the section "Cisco Connection Online," for details. Refer to Table 1<Xref_Color> for a description of the LEDs.
LED | State | Description |
---|---|---|
The carrier card has passed initial power-up diagnostics tests and is operating normally. |
||
1The individual 6-port MICA modules do not include LEDs. |
Successful installation of the new MICA modem carrier card requires these steps:
1. Upgrade the Cisco IOS image
2. Upgrade the Boot Flash image
3. Install the MICA carrier card
4. Upgrade modem code (optional)
See the following sections for details.
If you own a SMARTnet contract, you can obtain the Cisco IOS image at Cisco's Software Center home page at the following URL (this is subject to change without notice):
Before you physically install your new 6-port MICA carrier card, you must upgrade the boot Flash image in the access server boot Flash memory.
For DC-powered units only, note the following warning:
To install a new MICA module carrier card (see Figure 2), do the following:
Step 2 Slide the carrier card into the slot until it touches the backplane connector.
Step 3 Align the captive screws with their holes, and then seat the carrier card completely.
Step 4 Tighten the two captive screws to secure the carrier card to the chassis.
Step 5 If the access server is configured with fewer than three cards, ensure proper airflow inside the chassis by installing a blank slot cover is installed over each open slot. Note that you can order blank slot covers from Cisco. The part number is AS52M-BLANK=.
For DC-powered units only, note the following warning:
To remove the MICA carrier card, perform the following steps:
Step 2 Power OFF the access server.
Step 3 On the back of the access server, locate the MICA carrier card (see Figure 1).
Step 4 Loosen the two captive screws that secure the carrier card to the chassis until each screw is free of the chassis (see Figure 2).
Step 5 Hold the captive screws and gently pull the carrier card free of the chassis. If the card is hard to remove, insert a flat-head screwdriver vertically into the left and right sides of the board and gently pry the board loose (see Figure 3). Then, hold the captive screws and gently pull out the carrier card.
Step 6 Set the removed carrier card aside on an ESD-preventive mat.
To remove the 6-port MICA modules, perform the following steps:
Step 2 On the carrier card, locate the 6-port MICA module you will replace (see Figure 4).
Step 3 Orient the module so that the MICA module socket faces away from you.
Step 4 Gently pry the edges of the 6-port MICA module away from the standoffs, as shown in Figure 5.
Step 5 Push the two socket latches away from the MICA module, as shown in Figure 6.
Step 6 Remove the MICA module from its socket, as shown in Figure 7.
To install a 6-port MICA module:
Step 2 Seat the 6-port MICA module in the socket and press its edges onto the standoffs, as shown in Figure 8.
Modem code is a generic term applied to a modem code file, which is also called portware for MICA modems and firmware for Microcom modems.
With new systems, Cisco loads a Cisco IOS software-compatible version of modem code and copies the version to the installed modem modules. A map of the version(s) of modem code copied to the modem RAM for each modem module is stored in nonvolatile random-access memory (NVRAM) so that it is retained over power cycles.
Note You do not have to take any action to use the pre-installed version of modem code with new systems.
You can acquire new modem code in several ways:
This section describes how to upgrade modem code on your access server modems by:
1. Understanding the modem code scenarios possible for your access server.
2. Choosing an upgrade strategy.
3. Finding out the modem code version installed on your access server.
You can obtain modem code in one of two ways:
There are several commands you use to upgrade modem code. For examples on using the commands, see "Upgrading Modem Code from the Cisco CCO TFTP Server," "Upgrading Modem Code from Diskettes," and "Using the Modem Code Bundled with Cisco IOS Software," later in this document, for details.
Because of multiple versions of modem code and the way Cisco IOS software processes these versions, Cisco suggests that you choose one of the following two strategies:
To help with the decision, Figure 9 shows a hypothetical release process. Using the modem code bundled with Cisco IOS software is the easier strategy and enables you to take advantage of new modem code whenever you upgrade your Cisco IOS software. Note that you can also control the modem code by reverting to previous versions using the copy command as discussed later.
Table 2 provides scenarios that can occur when you upgrade Cisco IOS software or modem code.
No. | Scenario | Update Process |
---|---|---|
You update Cisco IOS software, and decide to use the version of modem code selected by Cisco IOS software. |
||
You update Cisco IOS software, and decide not to use the modem code selected by Cisco IOS software. |
|
|
The modems are running a version of modem code from boot Flash memory that is different than the version bundled with Cisco IOS software. You decide to revert to the bundled version. |
|
|
Cisco releases new modem code, which is a later version than the version currently running on the modems. You decide to use the new Cisco modem code.3 |
|
1To find out the version of modem in your system, use the show modem mapping command. This command displays the versions bundled with Cisco IOS software (copied into Flash memory) and running on the modems.
2 In part, Cisco IOS software bases this decision on the last copy command issued. For more details about mapping, see Table 4. 3 Cisco might ship this modem code on a diskette packed with the 6-port MICA module. |
Figure 10 shows a release timeline and Table 3 explains the resulting versions of Cisco IOS software and modem code.
1This example assumes the last copy command was copy bootflash modem, and Modem Code Version 1 was specified. |
Table 4 provides a list of modem code terminology and a description of how the terms are used in the modem code update process.
1This command is supported in Cisco IOS Releases 11.2(11)P and 11.3(2)T. |
Use the show modem mapping command to list all modem code files in the boot Flash memory, system Flash memory, and the modem code files bundled with Cisco IOS software. This will help you decide if you need to update your modem code files.
Upgrading modem code from the Cisco CCO TFTP server is a two-step process:
You can download software from the CCO TFTP server using an Internet browser or FTP application. Both procedures are described below.
Note To download modem code from CCO to a PC and then upgrade the modem code to an access server connected to your PC via an Ethernet hub, you need to set up a TFTP application on your PC, establish a HyperTerminal session, and make sure your PC and access server are correctly connected and talking before downloading the modem code from CCO. All these procedures are described in "Upgrading Modem Code from Diskettes," later in this document.
Step 2 Bring up the Cisco Software Center home page at the following URL (this is subject to change without notice):
http://www.cisco.com/kobayashi/sw-center/
Step 3 Click Access Products (under Cisco Software Products) to open the Access Products window.
Step 4 Click Cisco AS5200 Series Software.
Step 5 Click the modem code you want and download it to your workstation or PC.
Step 6 Click the modem code file you want to download, and then follow the remaining download instructions. If you are downloading the modem code file to a PC, make sure you download it to the c:\tftpboot directory; otherwise, the download process will not work.
Step 7 When the modem code is downloaded to your workstation, transfer the file to a TFTP server in your LAN using a terminal emulation software application.
Note The directory path leading to the modem code files on cco.cisco.com is subject to change without notice. If you cannot access the files using an FTP application, try the Cisco Software Center URL http://www.cisco.com/kobayashi/sw-center/.
Step 2 Enter your CCO registered username and password (for example, harry and letmein):
Step 3 Specify the directory path that holds the modem modem code you want to download. For example, the directory path for the Cisco AS5200 modem code is /cisco/access/5200:
Step 4 View the contents of the directory with the ls command:
Step 5 Specify a binary image transfer:
Step 6 Copy the modem code files from the Cisco AS5200 to your local environment with the get command.
Step 7 Quit your terminal session:
Step 8 Verify you successfully transferred the files to your local directory:
Step 9 Transfer these files to a local TFTP or RCP server that your access server can access.
The procedure for copying the modem code file from your local TFTP server to the modems involves two steps. First, you need to transfer the code to the access server's boot Flash memory. Then, you need to transfer the code to the modems.
These two steps are performed only once. After you copy the modem code file into boot Flash memory for the first time, you should not have to perform these steps again. Because the modem code runs from modem RAM, the Cisco IOS software automatically copies the modem code to each modem each time the access server power cycles.
Perform the following steps to download modem code to MICA modems:
Step 2 Enter the access server enable mode (the prompt is displayed as 5200#):
Step 3 Check the files in the access server boot Flash memory:
Step 4 Download the modem code file from TFTP server into the access server boot Flash memory using the copy tftp bootflash command. After you enter the command, you are prompted for the download destination and the remote host name as requested by the system software.
Step 5 Verify the file has been copied into the access server boot Flash memory:
Step 6 Copy the modem code file from the access server boot Flash memory to the modems by entering the copy bootflash modem command:
Note The modem code is downloaded to the module, not the individual slot/ports as indicated by the screen display.
This section describes how to copy modem code from diskettes to your hard disk in a PC environment, and then upload the modem code to the modems. The steps are similar if you are using a Macintosh or UNIX workstation.
Note If you loaded Cisco IOS software from a feature pack CD-ROM using Router Software Loader (RSL), note that the CD contains a TFTP server program for PCs using Microsoft Windows 95. Run the TFTP server program from the directory where you installed the RSL program. Remember to set the root directory to the directory where the Cisco AS5200 modem code is located. The RSL and the TFTP applications are also available on CCO in the software library in the Access Products section.
This section describes how to copy the modem code file to your hard disk in a PC environment. The steps are similar if you are using a Macintosh or a UNIX workstation.
Step 2 Use Microsoft Windows 95 Explorer to create a folder named tftpboot at your hard disk root c:.
Step 3 Use the Microsoft Windows 95 Explorer to copy the modem code file into the c:/tftpboot folder.
If you are using a PC running Microsoft Windows 95, installing the modem code from a hard drive onto a Cisco AS5200 involves installing a TFTP application on your PC, connecting your PC and the access server, establishing a HyperTerminal session on your PC, pinging the PC and access server to make sure they are talking to each other, copying the modem code from the PC to the access server, and then mapping the modem code to the modems. See the following sections for details.
Note You can use any TFTP or RCP application available from independent software vendors. A number of TFTP programs are also available as shareware from public sources on the World Wide Web. If you are using Microsoft Windows 95, you can also download a TFTP application (as zipped files) from the Cisco Software Center at the URL http://www.cisco.com/kobayashi/sw-center/.
Step 2 Launch the TFTP application by double-clicking the application icon or its filename.
Step 3 Set your TFTP server root directory:
In this step, you connect your PC and access server.
Note You can also connect your PC Ethernet port directly to the Cisco AS5200 Ethernet port using the 10BaseT crossover cable provided.
Step 2 Connect your PC COM port to the Cisco AS5200 console port, as shown in Figure 11.
Step 3 Make sure your PC and access server are powered on.
Use the steps in this section to establish a HyperTerminal session from your local PC to the Cisco AS5200. You will use the HyperTerminal session to talk to the access server.
Step 2 Double-click Hypertrm.exe to display the Connection Description dialog box.
Step 3 Enter a name for your connection (for example, Console) and click OK. HyperTerminal displays the Phone number dialog box.
Step 4 Choose the COM port connecting the PC and the access server in the Connect using list box. You have options to connect directly to one of four COM ports.
Step 5 Click OK. HyperTerminal displays the COM Properties dialog box.
Step 6 Choose these options in the COM Properties dialog box:
Step 7 Click OK. The HyperTerminal dialog box appears.
Step 8 Press Enter to display the 5200# prompt.
Note If the access server prompt does not appear, you might have selected the wrong COM port, the cable connections could be incorrect or bad, or the access server might not be powered on.
Ping the access server and the PC to make sure they are talking to each other and there are no configuration problems on your access server.
(a). Choose Start/Run to display the Run dialog box.
(b). Enter winipcfg and click OK to display the IP Configuration dialog box.
(c). Choose the PC Ethernet adapter connector used for the connection to the access server if you have more than one Ethernet adapter connector installed on your PC.
Note Enter the show running config command at the 5200# prompt to verify the access server has an IP address assigned. If the access server does not have an IP address, assign an IP address before continuing.
Step 2 In the HyperTerminal dialog box (see the previous section "Establish a HyperTerminal Session" for details), enter the access server enable mode (the prompt is displayed as 5200#):
Step 3 Enter the ping command with your PC IP address:
The access server displays five exclamation points (!) if everything is working and it displays five dots (.) if there is a problem. In the latter case, check the cabling between the router and the PC and check the access server configuration.
The procedure for copying the modem code file from your PC set up as a local TFTP server to the access server boot Flash memory is a two-step process.
These two steps are performed only once. After you copy the modem code file into boot Flash memory for the first time, you should not have to perform these steps again. Because the modem code runs from modem RAM, the Cisco IOS software automatically copies the code to each modem each time the access server power cycles.
Step 2 Download the modem code file from the TFTP server into the access server boot Flash memory using the copy tftp bootflash command. After you enter the command, you are prompted for the download destination and the remote host name as requested by the system software.
Step 3 Verify the modem code file has been copied into the access server boot Flash memory:
Step 4 Copy the modem code file from the access server boot Flash memory to the modems by entering the copy bootflash modem command:
Note The modem code is downloaded to the module, not the individual slot/ports as indicated by the screen display.
Use this procedure to update modem code on the modems in your access server if you decide to use the version of modem code bundled with Cisco IOS software instead of the version already mapped to your modems.
To set the modem code mapping to the modem code version bundled with Cisco IOS software, enter the following commands.
Step 2 Enter the copy system:/ucode/filename modem command (or, for Cisco IOS releases earlier than 11.2A or 12.0, the copy ios-bundled modem command):
The copy system:/ucode/filename modem (or copy ios-bundled modem) command does not affect any existing modem code in boot Flash memory in case you later want to revert to it. If you decide to delete the code from boot Flash memory, remember that all files in boot Flash memory will be deleted, therefore save and restore any important files (for example, the Cisco IOS software image).
Note If the new Cisco IOS image contains the same modem code as the old one, no new code will be downloaded to the modems.
This section explains how to display options for a command. To display options for a command, enter a ? at the configuration prompt or after entering part of a command followed by a space. The configuration parser displays options available with the command. For example, if you were in global configuration mode, typed the command arap, and wanted to see all the keywords and arguments for that command, you would type arap ?.
Table 5 shows examples of this function.
If you need further assistance, refer to the sections "Cisco Connection Online" and "CD-ROM/WWW Feedback," later in this document, for more information.
Take the following steps to configure the 6-port MICA modules:
Step 2 Configure the modems.
Step 3 Configure modem pooling.
Step 4 Configure the controllers.
Step 5 Configure the serial interfaces.
Step 6 Configure R2 signaling.
Use the following table to configure the asynchronous group interface. You can assign the asynchronous interfaces to a group so that you can configure them as a group, instead of individually. Use the commands in Table 6 to configure the asynchronous group interfaces.
To verify your group interface configuration, use the following command.
Check for errors and the local and remote addresses.
Configure the modems to allow users to dial in to your network by using the commands in Table 7.
Step | Command | Purpose |
---|---|---|
1 |
You have entered enable mode when the prompt changes to 5200#. |
|
2 | Enter global configuration mode. You have entered global configuration mode when the prompt changes to 5200(config)#. |
|
3 |
Specify the country to set the modem parameters (including country code and encoding) for MICA modems. The default is usa if the access server is configured with T1 interfaces and e1-default if the access server has E1 interfaces. |
|
4 | Enter the number of modem lines to configure. If you have 48 modems, enter line 1 48. If 60, enter line 1 60. |
|
5 | ||
6 | Enable remote IP users running a PPP application to dial in, bypass the EXEC facility, and connect directly to the network. |
|
7 | ||
8 |
Return to enable mode. |
Table 8 lists the current MICA modem codes.
Country | Code | Country | Code |
---|---|---|---|
To reset to default settings for country codes, enter the following commands in global configuration mode:
Use modem pooling to define, select, and use separate pools of modems within a single access server to enable different dial-in services for different customers. The primary application is to allocate specific modems based on called party numbers and a predetermined number of modem ports based on Dialed Number Information Service (DNIS).
If you do not configure any modem pools, all the modems are placed into a single pool. There is no restriction on the number of modem pools that you can configure. A pool can contain a minimum of one modem and a maximum equal to all the modems in the system.
This section briefly shows how to set up a minimum configuration. For detailed information on using this feature, refer to the command reference documents shipped with your access server.
Note To support modem pooling over channelized T1 lines, you need to configure the lines as described in the following table. If you are using R2 signaling over channelized E1, you do not need any special configuration options since DNIS information is always collected.
To verify your modem pooling configuration:
Use Table 10 to configure the controllers.
Use Table 11 to configure the serial interfaces.
R2 signaling is an international signaling standard that is common to channelized E1 networks. You can configure a channelized E1 interface to support different types of R2 signaling, which is used in older analog telephone networks. Note that this feature is available for MICA modems. UseTable 12 to configure R2 signaling.
Step | Command | Purpose |
---|---|---|
1 |
You have entered enable mode when the prompt changes to 5200#. |
|
2 | Enter global configuration mode. You have entered global configuration mode when the prompt changes to 5200(config)#. |
|
3 | Enter controller configuration mode to configure your E1 controller port. The E1 controller ports are labeled 0 and 1 on the E1/PRI cards. |
|
4 |
Configure framing to E1 with CRC1. |
|
5 |
Configure line code to AMI2 encoding. |
|
6 |
Configure the clock source to the internal clock. |
|
7 | Configure the timeslots that belong to each E1 circuit for R2 signaling. Sets R2 signaling to R2 ITU Q411, the tone signal to R2 Compelled Register Signaling, and the ANI addr info provisioned option. R2 line signaling options include: r2-analog, r2-digital, and r2-pulse. Tone signaling options include dtmf (default), r2-compelled, r2-non-compelled, and r2-semi-compelled. You can also set ani (ANI addr info provisioned) for any of the above options. |
|
8 | ||
9 | Use defaults for the specified country. Note: To view the parameters for the country (if the country defaults are the same as ITU defaults), enter write term. The default setting for all countries is ITU. See "Country Codes for R2 Signaling" later in this section for a list of supported countries. |
|
10 | Set the cas custom command answer-signal to group-b to 6.
Cas custom commands include: caller-digits, category, country, unused-abcd, invert-abcd, metering, ka, kd, dnis-digits, answer-signal, and nc-congestion. Reset answer-signal group-b 6 to the default value.
Note: The parameters you do not set are automatically set to the ITU default by the Cisco AS5200. |
|
11 |
1CRC = Cyclic Redundancy Check.
2AMI = Alternate Mark Inversion. 3HDB2 = Line code type used on E1 circuits. |
Table 13 lists the country codes supported for R2 signaling.
To verify your R2 signaling configuration:
If you are having trouble, enable the modem management Call Switching Module (CSM) debug mode using the following command.
This is the output of debug modem csm for an incoming call:
