Chapter 4: System Modules
Module Redundancy
A blade system must have one CMM and may have two for redundancy is offered only
on a specific enclosure model, which has the hardware capability to incorporate two
CMM's on one backplane. 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.
Determining Master/Slave Modules Status
When a blade system has two CMM modules, they are assigned a master/slave status.
This is done automatically with the default primary CMM specified for per each
enclosure, while there will be no redundant in certain enclosures.
If the master CMM is powered down or removed (or is being reset by its user), the
second (slave) CMM module will then immediately be assigned as the master. The
redundant CMM mode is only offered on specific chassis models. The slave uses the
previous master IP config in case of a fail over.
NOTE: The Slave CMM keeps the same log/status as the Master CMM and uses the
previous master IP config.
CMM Module Installation
Use this procedure to install the MBM-CMM-FIO or MBM-CMM-001 CMM module to the
8U SuperBlade chassis. Make sure the cover to the module has been installed before
proceeding. Follow the anti-static precautions described in
Chapter 2 .
Installing the Module:
1. Remove the dummy cover from the bay you want to place the module in.
2. Place the module's release handle in the open position.
3. Slide the module into the module bay until it stops.
4. Push the release handle to the closed position.
