Upgrading Modem Code from Diskettes for Access Servers

Upgrading Modem Code from Diskettes for Access Servers

Modem code is a generic term applied to a modem code file, which is also called modem code 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.

Occasionally, Cisco Systems ships you modem code on diskette that fixes existing bugs, provides a special feature, or changes performance.

This document includes the following sections:

Required Tools

You need the following tools:

Note The PC, Macintosh, or UNIX workstation used for the upgrade and the access server you are upgrading must have the same subnet mask.

Displaying Modem Code Versions

Cisco AS5200 Access Servers

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.

This is an example for Microcom modems.

Upgrading Modem Code From Diskettes

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 access server modems. The steps are similar if you are using a UNIX workstation.

Upgrading modem code from diskettes is a two-step process:

    1 . Copying Modem Code to Your Hard Disk

    2 . Copying Modem Code from Your PC to the Modems

Copying Modem Code to Your Hard Disk

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 1 Insert the modem code diskette into the PC diskette drive.

Step 2 Use Microsoft Windows 95 Explorer to create a folder tftpboot at your hard disk root c:.

Step 3 Use the Microsoft Windows 95 Explorer to copy the modem code file into your c:/tftpboot folder.

Copying Modem Code from Your PC to the Modems

If you are using a PC running Microsoft Windows 95, installing the modem code from a hard drive onto a Cisco AS5200 involves:

    1 . Installing a TFTP application on your PC

    2 . Connecting your PC and the access server

    3 . Establishing a HyperTerminal session on your PC

    4 . Pinging the PC and access server to make sure they are talking to each other

    5 . Copying the image from the PC to the access server.

See the following sections for details.

Note The steps are similar if you are using a Macintosh or a UNIX workstation.

Installing a TFTP Application on the PC

Note You can also use an 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.

Step 1 Insert the TFTP diskette (provided by Cisco) in the PC diskette drive.

Step 2 Use the Microsoft Windows 95 Explorer to create a directory labeled tftp on your hard disk.

Step 3 Copy the TFTP files from the diskette to the directory created in Step 2. The TFTP files include tFTPSERV.EXE, TFTPSERV.DLL, MFC42.DLL, and MSVCRT.DLL.

Step 4 Double-click tftpsrv.exe in the Microsoft Windows 95 Explorer to launch the TFTP application.

Step 5 Set your tftp server root directory in the TFTP application:


Caution If you do not select the c:\tftpboot directory as your TFTP server directory, you will not be able to perform the copy procedure. This also applies if you are using rcp on your system.

Connecting your PC and the Access Server

Step 1 Use straight-through cables to connect the PC and access via a 10BaseT hub, as shown in Figure 1. Also note that both Ethernet ports must have the same baseband.


Figure 1: Connecting a PC and an Access Server

Step 2 Connect your PC's COM port to the access server console port. See Figure 1 for details.

Step 3 Make sure your PC and access server are powered on.

Establishing a HyperTerminal Session

Use the steps in this section to establish a HyperTerminal session from your local PC to the access server. You will use the HyperTerminal session to talk to the access server.

Step 1 In Microsoft Windows 95 on your PC, choose Start/Programs/Accessories/HyperTerminal.

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 then 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 as5x00> prompt.

Step 9 Enter the enable mode by entering the enable command and the password:

Pinging the PC and Access Server

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.

Step 1 Choose the correct Ethernet adapter connecting to the access server and note the PC's IP address:

Step 2 In the HyperTerminal dialog box (see "Establishing a HyperTerminal Session" for details), make sure you are at the as5x00# prompt.

Step 3 Enter the ping command with your PC's 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.


Step 4 To upload modem code to Cisco AS5200 access servers, continue with the section "Uploading Modem Code to Cisco AS5200" and to upload modem code to Cisco AS5300 access servers, continue with the section "Uploading Modem Code to Cisco AS5300."

Uploading Modem Code to Cisco AS5200

The procedure for copying the modem code file from your PC set up as a local TFTP server to the access server system Flash memory is a two-step process.

These two steps are performed only once. After you copy the modem code file into system 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.

Perform the following steps to download modem code to MICA modems:

Step 1 Check the image in the access server boot Flash memory:

Step 2 Download the modem code file from the tftp server into the access server Flash memory using the copy tftp flash command in EXEC mode. 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 file has been copied into the access server boot Flash memory:

Step 4 Copy the modem code file from the access server Flash memory to the modems by entering the copy bootflash modem privileged EXEC command:

Step 3 Verify the file has been copied into the access server Flash memory:

Step 4 Copy the code file from the access server Flash memory to the modems by entering the copy flash modem Privileged EXEC command.
