Caution During the download of the upgrade file, the switch might not respond to commands for as long as 1 minute. This is normal and correct. If you interrupt the download by turning the switch off and on, the firmware could be corrupted. If this happens, restart the firmware following the procedure described in the "Using the Diagnostic Console" section in the "Troubleshooting" chapter of the Catalyst 1900 or Catalyst 2820 installation documents.

How you upgrade the firmware depends on your installation:

• From a TFTP server---First enter the name of the TFTP server and the name of the file containing the upgrade. The upgrade can be initiated through the management console or with any SNMP-compatible management station. The switch retrieves the upgrade file from the server through TFTP.

• From a TFTP client---The upgrade can be done via a TFTP client.

• With the XMODEM protocol---The upgrade can be done via the XMODEM protocol after you attach a management station to the console port on the switch.

[A] Accept upgrade transfer from other hosts---Enable [E] or disable [D] the switch from accepting an upgrade from another host on the network. To prevent unauthorized upgrades, use the Disabled setting. The default setting is Enabled.

[D] Download test subsystem (XMODEM)---For Cisco personnel only.

[X] Exit to Main Menu---Display the Management Console Main Menu.

To download the switch firmware via XMODEM, follow these steps:

Step 1 Enter the baud rate (2400, 9600, 19200, 38400, or 57600) of the console port on the switch and the management station. You can set the baud rate for the console port from the RS-232 Port Configuration Menu.

Step 2 From the Firmware Configuration Menu, select the [U] option to use the XMODEM protocol to download the upgrade file.

Step 3 At the prompt, select Y to start the download.

To download the module firmware from a TFTP server, follow these steps:

Step 1 From the Firmware Configuration Menu, select the [S] option, and enter the
IP address or name of the TFTP server where the FDDI or ATM upgrade file is located.

Step 2 Select the [F] option from the menu, and enter the name of the upgrade file.

Step 3 Select the [3] option (for slot A) or the [4] option (for slot B) to initiate the TFTP download.

The switch contacts the server to download the upgrade file to the switch.

Step 4 Verify the upgrade is in progress by checking the System Information section of the Firmware Upgrade Menu.

If the upgrade is in progress, the field reads in-progress.

When the download is complete, the FDDI or ATM module resets and begins using the new firmware.

Step 2 Ensure that the TFTP client is in binary transfer mode.

Step 3 Use the appropriate command (such as, put upgrade_filename) to download the upgrade file from the client workstation to the switch.

If there are two FDDI or two ATM modules installed, the following rules apply:

• If the firmware in one of the modules is invalid, it is automatically upgraded.

• If the upgrade firmware has a higher version number than the firmware in
  slot A, then the firmware in slot A is upgraded.

• If the firmware in slot A has the same or a higher version number than the upgrade firmware, then the firmware in slot B is upgraded.

Step 4 Verify the upgrade is in progress by checking the System Information section of the Firmware Upgrade Menu.

If the upgrade is in progress, the field reads in-progress.When the download is complete, the FDDI or ATM module resets and begins using the new firmware.

Step 1 Enter the baud rate (2400, 9600, 19200, 38400, or 57600) of the console port on the switch and the management station. You can set the baud rate for the console port from the RS-232 Port Configuration Menu.

Step 2 From the Firmware Configuration Menu, select the [U] option to use the XMODEM protocol to download the upgrade file.

Step 3 Select the [1] option (for slot A) or the [2] option (for slot B).

Step 4 At the prompt, select Y to start the download.

Step 5 Verify the upgrade is in progress by checking the System Information section of the Firmware Upgrade Menu.

If the upgrade is in progress, the field reads in-progress.

When the download is complete, the FDDI or ATM module resets and begins using the new firmware.

[S] Server: IP address of TFTP server---Enter the IP address of the TFTP server where the upgrade file is located.

[F] Filename for firmware upgrades---Enter the name of the firmware upgrade file to be downloaded, and press Return.

[A] Accept upgrade transfer from other hosts---You have the option of accepting upgrades from TFTP clients on the network. Use this option to enable or disable this function, and press Return.

[1] FDDI or ATM (A) XMODEM upgrade---Start an XMODEM upgrade of the FDDI or ATM firmware in expansion slot A.

[2] FDDI or ATM (B) XMODEM upgrade---Start an XMODEM upgrade of the FDDI firmware in expansion slot B.
