ICMB Connect ors

The ICMB device provides external access to the ICMB devices that are within the chassis. This

makes it possible to externally access chassis management functions, alert logs, post-mortem data,

etc. The device also provides a mechanism for chassis power control. The server provides two

SEMCONN 6-pin connectors to allow daisy-chained cabling.
