Recovering a Switch

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 using maintenance mode. Maintenance mode temporarily returns the switch IP address to 10.0.0.1 and provides opportunities to do the following:

„Unpack a firmware image file

„Restore the network configuration parameters to the default values

„Remove all user accounts and restore the Admin account name password to the default.

„Copy the log file

„Restore factory defaults for all but user accounts and zoning

„Restore all switch configuration parameters to the factory default values

„Reset the switch

„Display firmware versions stored on the switch

„Select the firmware image to activate

To recover a switch, do the following:

1.Place the switch in maintenance mode. Press and hold the Maintenance button with a pointed tool for 2–4 seconds. When the Input Power LED alone is illuminated, release the button.

2.Allow one minute for the switch to complete its tests. When the switch is in maintenance mode, the Input LED will be illuminated and the Heartbeat LED will illuminate continuously. All other chassis LEDs will be extinguished.

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 [username@anteater:Itasca]% telnet 10.0.0.1 Trying 10.0.0.1...

Connected to 10.0.0.1. Escape character is '^]'.
