The BladeCenter modules
The BladeCenter unit contains the following hot-swap modules:
v Management modules
v I/O modules
v Blade servers
v Power modules
v Blower modules
See “Front view” on page 14 and “Rear view” on page 16 for the location of each
module.
The BladeCenter unit and the active management module make optional I/O
devices (CD/DVD drive, USB port, keyboard, video, and mouse) available to all the
blade servers, selected by any one blade server at a time.
Management modules
The BladeCenter unit comes with at least one hot-swap management module in
management-module bay 1. An optional second management module in
management-module bay 2 provides management redundancy. The management
modules are hot-swap BladeCenter modules that you use to configure and manage
all installed BladeCenter components.
The type of management modules that are installed in your BladeCenter unit
depends on the BladeCenter unit model and devices that are installed. When two
modules are installed they must be the same type.
v A BladeCenter unit that has a media tray with a diskette drive can use either
management modules or advanced management modules, depending on which
devices are installed in the BladeCenter unit.
v A BladeCenter unit that has a media tray without a diskette drive must use
advanced management modules.
v If 2320-watt power modules are installed in the BladeCenter unit, you must use
advanced management modules.
v See the documentation that comes with your BladeCenter device to determine if
specific management modules are required to support the device.
See the User's Guide or the Command-Line Interface Reference Guide for your
management module type for more information.
