When the standby module is not available

If you have disabled management module redundancy with the no redundancy management-module command, or the standby module failed selftest, the Dwn LED does not turn green to indicate it is OK to hotswap out the active management module.

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.
