Disable management module redundancy with only one module present

If you disable redundancy when there is only one management module in the switch, and then you insert a second management module, the second module never goes into standby mode. You must re-enable redundant management using this command:

switch# redundancy management-module

The currently active module remains active on boot (assuming no selftest failure) unless you make the newly inserted management module active using this command:

switch# redundancy active-management standby

The standby management module becomes the active management module.
