Management and Configuration Guide K/KA/KB.15.15

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.
NOTE: If you remove the active management module without pressing the MM Shutdown button,
any files that may have been in the process of synchronizing will not finish synchronizing to the
standby module and all file transfer is aborted.
Resetting the management module
The MM Reset button, shown in Figure 254 (page 471), found on each management module reboots
its management module. If the management module is active and management module redundancy
is enabled, switchover occurs. The standby management module is notified immediately. It then
takes over and becomes the active management module. If the MM Reset button is pressed on the
standby management module, that module reboots but no other switch operations are affected.
The active management module remains in control.
If management module redundancy is disabled, the active management module reboots and
remains in control, as long as it passes selftest.
CAUTION: HP does not recommend using the MM Reset button to trigger a switchover. Files
being copied over at the time of the reset will be aborted.
