Advanced management module
The advanced management module is a hot-swap module that you use to
configure and manage all installed BladeCenter components. The BladeCenter S
chassis comes with one advanced management module in the advanced
management module bay.
The advanced management module provides systems-management functions and
keyboard/video/mouse (KVM) multiplexing for all blade servers in the
BladeCenter S chassis that support KVM. It controls the following connections:
v A serial port for a local connection to another computer, such as a notebook
computer
v The external video and USB connections for keyboard and mouse
v A 10/100 Mbps Ethernet connection
The advanced management module communicates with the service processor (also
called the baseboard management controller, or BMC) 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 S chassis shared media tray.
