Hotswapping Out the Active Management Module
You can hotswap out the active management module and have switch
operations taken over by the standby management module by following the
correct shutdown procedure on the active module using the MM Shutdown
button. When the MM Shutdown button is pressed, any file synchronization
in progress completes before the shutdown begins, and then a graceful
shutdown of that management module occurs.
1. On the management module to be hotswapped out, press the MM Shut-
down button. It is located between the Module Operation and Component
Status LEDs. See Figure 15-9.

2. The Dwn LED to the right of the MM Shutdown button will begin flashing
green. File synchronization will complete before shutdown occurs.
3. The standby module takes control and the switchover occurs. It is now
the active management module.
4. The Dwn LED on the management module being hotswapped out turns
green and all other LEDs go out when it is OK to remove the module.
5. The module being hotswapped out goes into offline mode. In the “offline”
mode, the module cannot take over when the active module fails over.
