Management module
The BladeCenter T unit comes with one hot-swap Advanced Management Module
in management bay 1. An additional management module can be added in
management-module bay 2. Only one of these management modules can be active
at one time, functioning as the primary management module; a second
management module, if present, provides redundancy. The secondary management
module remains inactive until it is switched to act as primary.
When two management modules are installed in the BladeCenter T unit, both
management modules must have the same level of firmware, at a level that
supports redundant management-module function. This helps ensure a smooth
changeover of control from the active management module to the redundant
management module. The latest level of management-module firmware is available
at the IBM Support Web site at www.ibm.com/pc/support/.
The management module functions as a service processor and a KVM multiplexor
for all of the blade servers installed in the BladeCenter T unit. It controls the
KVM-module external connections for use by a local console. The management
module also controls three LAN-module external connections: two RJ-45 connectors
for 10/100-Mbps Ethernet remote management connection and an alarms connector
that can be used for monitoring BladeCenter T unit status.
The service processor in the management module communicates with the service
processor in each blade server to support features such as blade server power-on
requests, error and event reporting, KVM requests, and requests to use the
BladeCenter T shared-media tray (CD-ROM drive and USB port)
The BladeCenter T components are configured using the management module. The
management module communicates with all components in the BladeCenter T unit,
detecting their presence or absence, reporting their status, and sending alerts for
error conditions when they are required (see Figure 10 on page 26).
