Configuring Protected Mode
Although you cannot enable protected mode on a stack member, if protected mode is enabled on the
stack master, this feature is enabled on all stack members. Before using protected mode on a switch
stack, consider the feature interactions.
Caution To prevent physical damage to the switch, if protected mode is enabled and the AMM detects an
overtemperature or overcurrent condition, the AMM can still reboot or power off the switch.
Configuration Guidelines and Restrictions
Follow these guidelines and restrictions when enabling and disabling protected mode:
• Before you enter the platform chassis-management protected-mode global configuration
command on the switch, you must enable protected mode on the AMM . For information about
enabling protected mode on the AMM, see the AMM documentation at this URL:
http://www-304.ibm.com/jct01004c/systems/support/supportsite.wss/brandmain?brandind=50000
