3. Replace the Fibre Channel port cable. Is the problem corrected?

• Yes  -  Complete.

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

•

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.
