• CMC reset — Chassis management resumes after CMC reboots or chassis fails over to the standby CMC.
• CMC failover command issued — Chassis management resumes after the chassis fails over to the standby CMC.
• CMC rmware update — Chassis management resumes after CMC reboots or chassis fails over to the standby CMC. It is
recommended that you update the standby CMC rst so that there is only one failover event.
• CMC error detection and correction — Chassis management resumes after CMC resets or chassis fails over to the standby CMC.
NOTE: You can congure the enclosure either with a single CMC or with redundant CMCs. In redundant CMC congurations, if
the primary CMC loses communication with the enclosure or the management network, the standby CMC takes over the chassis
management.
Active CMC Election Process
There is no dierence between the two CMC slots; that is, slot does not indictate precedence. Instead, CMC that is installed or started
rst, assumes the role of an active CMC. If AC power is applied with two CMCs installed, CMC installed in CMC chassis slot 1 normally
assumes the active role. The active CMC is indicated by a blue LED.
If two CMCs are inserted into a chassis that is already turned on, automatic active- or standby negotiation can take upto two minutes.
Normal chassis operation resumes when the negotiation is complete.
Obtaining Health Status of Redundant CMC
You can view the health status of the standby CMC in the web interface. For more information about accessing CMC health status in the
web interface, see Viewing Chassis Information and Monitoring Chassis and Component Health.
