module you are removing before you remove it. (See the documentation that
comes with the blade server for instructions for shutting down the blade
server operating system and turning off the blade server.)
b. If you are removing a management module, you might prefer to stop all
management module local and remote sessions before proceeding, to avoid
unexpected termination of sessions.
3. Disconnect any cables from the module. For a power module, disconnect the
power cord from the module.
4. Pull the release lever all the way toward the bottom of the module until it stops,
as shown in the illustration. The module moves out of the bay approximately 0.6
cm (0.25 inch).
5. Slide the module out of the bay and set it aside. Within 1 minute, place either
another module of the same type or a filler module in the bay.
6. If you placed another module in the bay, reconnect any cables or power cords
you disconnected in step 3; then, make sure the LEDs on the module indicate
that it is operating properly. Verify that:
v The dc power LED and the ac power LED on each power module are lit.
v The OK LED on the management module is lit.
v The OK LED on each I/O module is lit.
7. Replace the acoustic module option, if you removed it in step 2.
Installing and removing the acoustic module option
For server environments where noise reduction is essential, you might choose to
install the BladeCenter Acoustic Attenuation Module option (acoustic module), on
your BladeCenter unit. The acoustic module reduces the sound level of the
BladeCenter unit to below 6.9 bel using a T-shaped baffle. The acoustic module is
installed on the back of the BladeCenter unit, directly covering the blower modules
and partially covering the other modules. The system LED panel is replicated on the
acoustic module for visibility. Installing an acoustic module increases the length of a
BladeCenter unit and requires use of an enterprise rack.
