Installing and removing modules
The procedures for installing or removing a module on the BladeCenter unit are
nearly identical for all modules except the blower modules. To install or remove a
blower module, see the BladeCenter
Hardware Maintenance Manual and
Troubleshooting Guide on the BladeCenter Documentation CD. To install or remove
all other modules, follow the instructions in this section.
Every module is keyed so that it can be inserted only in an appropriate bay. You
can insert a switch module only in a switch-module bay, for example. In addition,
most modules must be installed in a specific sequence or under specific
circumstances.
The BladeCenter modules
Your BladeCenter unit contains the following hot-swap modules: power modules,
switch modules, management module, and blower modules. See “Rear view” on
page 33 for the location of each module. These modules supply common functions
to the blade servers that are installed in the blade bays in the front of the
BladeCenter unit.
The chassis and the management module supply I/O (diskette drive, CD-ROM
drive, USB port, keyboard, video, and mouse) that is available to all the blade
servers, selected by any one blade server at a time. The chassis can contain up to
14 blade servers.
Attention: To help ensure proper cooling, performance, and system reliability,
make sure that each of the module bays on the rear of the BladeCenter unit has a
module or filler module installed. When replacing a module, do not operate the
BladeCenter unit for more than one minute without either a module or a filler
module installed in each module bay.
Management module
Your BladeCenter unit comes with one hot-swap management module in the
management bay.
The management module functions as a service processor and a
keyboard/video/mouse (KVM) multiplexor for the multiple blade servers. The
management module also configures 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 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 Blade server requests for keyboard, mouse, and video
v Blade server requests for diskette drive, CD-ROM drive, and USB port
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.
