Management Module - IBM 8677 - BladeCenter Rack-mountable - Power Supply Planning And Installation Manual

Management module

The BladeCenter unit comes with one hot-swap management module in the
management bay.
The management module functions as a system-management processor (service
processor) and keyboard/video/mouse (KVM) multiplexor for the blade servers. The
management module is used to configure the BladeCenter unit and modules,
configuring such information as the switch IP addresses. The management module
provides the following external connections: keyboard, mouse, and video for use by
a local console, and one RJ-45 connector for a 10/100 Mbps Ethernet remote
management connection.
The network connection for the management module should be to a network that is
dedicated to network management tasks. This provides a greater level of security
and a different network path to the BladeCenter unit if you experience an outage on
the network path to the Ethernet switch modules.
The service processor in the management module communicates with the service
processor in each blade server for such functions as:
v Blade server power-on requests
v Blade server error and event reporting
v Requests for keyboard, mouse, and video (KVM) switching
v Requests for diskette drive, CD-ROM drive, and USB port switching
The management module also communicates with the switch modules, power
modules, blower modules, and blade servers to detect presence or absence and
any error conditions, sending alerts when required.
