About Standby CMC

The standby CMC is identical to and is maintained as a mirror of the active CMC. The active and standby CMCs must both be installed with the same firmware revision. If the firmware revisions differ, the system reports as “redundancy degraded”.

The standby CMC assumes the same settings and properties of the active CMC. You must maintain the same firmware version on both the CMCs, but you do not have to duplicate configuration settings on the standby CMC.

  • NOTE: For information about installing a CMC, see the VRTX Owner’s Manual. For instructions about installing CMC firmware on your standby CMC, see Updating Firmware .
