4–Diagnostics/Troubleshooting Recovering a Switch Using Maintenance Mode

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 1-11for 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.

Sanbox login: prom

Password:xxxx

Trying 10.0.0.1...

Connected to 10.0.0.1.
