1. Read the safety information beginning on page 87 and “Installation guidelines”
on page 31 through “Handling static-sensitive devices” on page 32.
2. Remove the acoustic module option, if installed, from the rear of the
BladeCenter unit. See “Installing and removing the acoustic module option” on
page 40 for instructions.
Important:
a. If you are removing a functional power module, make sure before you
remove the module that both the ac power LED and the dc power LED on
the remaining power module are lit and that the power module error LED
(2320-watt power modules only) on the remaining power module is not lit;
otherwise, shut down the operating systems, and turn off all blade servers
that are supported by the power 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 and
that the power module error LED (2320-watt power modules only) on each
power module is not 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.
