Recovering a Switch Using Maintenance Mode

59229-05 A 4-15

Recovering a Switch Using Maintenance Mode

A switch can become inoperable or unmanageable for the following reasons:

Firmware becomes corrupt

IP address is lost

Switch configuration becomes corrupt

Forgotten password

In these specific cases, you can recover the switch by placing the primary CPU

blade in maintenance mode. Maintenance mode temporarily returns the switch IP

address to 10.0.0.1 and provides opportunities to perform the following tasks:

Exiting the Maintenance Menu

Unpacking a Firmware Image File

Resetting the Network Configuration.

Resetting User Accounts

Copying Log Files

Removing the Switch Configuration

Remaking the File System\

Resetting a Blade

To recover a switch, do the following:

1. Place the switch in maintenance mode. Refer to “Placing the Switch in

Maintenance Mode” on page 1-11 for detailed instructions.

2. Allow one minute for the switch to complete its tests. When the switch is in

maintenance mode, the Heartbeat LED will illuminate continuously.

3. Establish a Telnet session with the switch using the maintenance mode IP

address 10.0.0.1.

4. Enter the maintenance mode account name and password (prom, prom),

and press the Enter key.
