Figure 271 Example of a software version mismatch between the active and standby modules
Downloading a software version serially if the management module is corrupted
If the software version on a management module becomes corrupted, you may need to do a serial
download to restore the affected module. The non-corrupted management module becomes the
active module. You can then use the serial port on the corrupted management module to download
a new software version. When the corrupted module is rebooted, the software version in the
corrupted module is immediately overwritten by the software version in the active management
module. Both management modules should now operate on the same software version.

Disable management module redundancy with two modules present
To troubleshoot a suspect management module, you may want to operate the switch with redundant
management disabled by entering this command:
(HP_Switch_name#) no redundancy management-module
After executing this command, the second management module will not boot into standby mode—it
is offline and no longer receives configuration file changes from the active module. The active
management module updates its config file with the information that redundancy is disabled.
NOTE: Even if redundancy has been disabled, the specified management module becomes the
active management module at the next system boot if you use the redundancy
active-management command. You are warned that you may not be using current configurations.
See “Setting the active management module for next boot” (page 468).
The second management module is enabled as the active management module in the event of a
hardware failure of the first management module.
