Chassis Management Module
The CMM’s primary function is to provide the bullx blade chassis-level management
functionality for the bullx blade system. This includes detection, power On/Off,
management status monitoring for the bullx B500 compute blades and other hardware
modules within the bullx blade chassis, PSU management status monitoring, and system fan
controls. The CMM is also used to manage and display the LCD messages.
The CMM is a hot-swappable module which includes of a 24-port 1GbE Ethernet switch
and an OPMA daughter card, which is used as a service processor.
The Ethernet logical connections are:
•
One Ethernet port to the OPMA service processor (internal)
•
Eighteen Ethernet ports to bullx B500 compute blades through backplane connector
(internal)
•
Three Ethernet ports to RJ45 connectors on the rear side for external access
