Chapter 4: System Modules
Module Redundancy
A blade system must have one CMM and may have two for redundancy. Since the CMM
uses its own processor, all monitoring and control functions are carried out regardless of
the operation or power status of the blade units. CMM modules can only be installed in
the upper and/or lower right module bays.
The redundancy feature is automatic when two CMM modules have been installed into a
blade system.
Master/Slave Modules
When a blade system has two CMM modules, they are assigned a master/slave status.
This is done automatically according to the following criteria:
Determining Master/Slave status:
1. The CMM installed in the upper bay will be the master, however...
2. If the master CMM is powered down or removed, the second (slave) CMM module
will then immediately be assigned as the master.
