Removing a module
The following illustration shows how to remove a typical BladeCenter unit module,
such as a power module, management module, or I/O module, from the rear of the
BladeCenter unit.
To remove a power module, management module, or I/O module, complete the
following steps:
Note: These instructions assume the BladeCenter unit is connected to power.
1. Read the safety information that begins on page v and “Installation guidelines”
on page 20 through “Handling static-sensitive devices” on page 20.
2. Remove the acoustic attenuation module, if one is installed, from the rear of the
BladeCenter unit. See “Removing an optional acoustic attenuation module” on
page 26 for instructions.
Important:
a. If you are removing a functioning power module, make sure that both the ac
power LED and the dc power LED on the remaining power module are lit
and the power-error LED is not lit; otherwise, shut down the operating
systems and turn off all blade servers that are supported by the power
module that you are removing before you remove it. See “Power modules”
on page 7 for more information about power-module application. 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, stop all management-module
sessions before you proceed, to avoid unexpected termination of sessions.
You can save the management-module configuration file before you remove
the management module. See your management-module User’s Guide for
instructions for saving the configuration file.
