Recovering a Switch Module

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

Update the system boot loader

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 2–7 seconds.

2.Allow one minute for the switch to complete its tests. When the switch is in maintenance mode, all switch module LEDs are 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.

Switch login: prom

Password:xxxx

5.The maintenance menu displays several recovery options. To select a switch recovery option, press the corresponding number (displayed in option: field) on the keyboard and press the Enter key.

0)Exit

1)Image Unpack

2)Reset Network Config

3)Reset User Accounts to Default

4)Copy Log Files

5)Remove Switch Config

6)Remake Filesystem

7)Reset Switch

8)Update Boot Loader
