Cisco Cisco Fiber IGESM Switch Module for IBM Release Notes

These guidelines and restrictions apply to protected mode:

Protected mode must be enabled on the chassis management module before you enter this command 
on the blade switch. For information about enabling protected mode on the chassis management 
module, see the management module documentation at this URL:

http://www-03.ibm.com/servers/eserver/support/bladecenter/index.html

After protected mode is operational on the switch, the management module cannot configure or 
administer the blade switch. 

The blade switch must be rebooted for protected mode to become operational.

Protected mode remains active even when the switch is moved to another chassis.

Recovery from lost passwords requires direct access through the external serial port on the switch.

Beginning in privileged EXEC mode, follow these steps to enable protected mode and prevent the 
management module from controlling the switch:
