7.3CMM Redundancy

When a chassis is powered up, the CMM determines which of the two CMMs is initially active. Once the CMM firmware is loaded, it runs an algorithm to determine which CMM is healthier—see the Intel NetStructure® MPCMM0001 Chassis Management Module and Intel NetStructure® MPCMM0002 CMM Software Technical Product Specification for more information.

During chassis initialization, the active CMM is the first one that meets the following criteria:

• NGOI is not asserted low, which would indicate the other CMM is already active.
