Dell PowerEdge M1000e Chassis Management Controller Firmware Version 5.1 User’s Guide

There are three types of invalid configurations:

• Invalid MC or LOM configuration, where a newly installed fabric type of the server is different from the existing IOM fabric, that is, LOM or MC of a single server is not supported by its corresponding IOM. In this case, all the other servers in the chassis are running, but the server with the mismatched MC card cannot be turned on. The power button on the server flashes amber to alert a fabric mismatch.
• Invalid IOM-MC configuration, where a newly installed fabric type of the IOM and the fabric types of the resident MC do not match or are incompatible. The mismatched IOM is held in the power-off state. CMC adds an entry to CMC and hardware logs noting the invalid configuration and specifying the IOM name. CMC causes the error LED on the offending IOM to blink. If CMC is configured to send alerts, it sends email and SNMP alerts for this event.
• Invalid IOM-IOM configuration, where a newly installed IOM has a different or incompatible fabric type from an IOM already installed in its group. CMC holds the newly installed IOM in turned-off state, causes the error LED of the IOM to blink, and logs entries in CMC and hardware logs about the mismatch.
