Redundancy (Switch 8212zl)

Hotswapping Management Modules

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 on the active management

module, any file synchronization in progress completes before the shutdown

begins, and then a graceful shutdown of that management module occurs.

Warning If redundancy is enabled, all the files on the hotswapped module are

overwritten with files from the active management module. The data that was

on the hotswapped module is lost.

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.

Figure 15-9. The MM Shutdown Button

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.
