power module bay.
About this task
Attention:
v To maintain proper system cooling, do not operate the BladeCenter S system
without a power module or power module filler in each power module bay.
Install a power module or filler within one minute of the removal of a power
module.
v If you are removing a functioning power module, make sure that power LEDs
on the remaining power modules are lit and the power management policy you
have chosen supports the removal of the power module. If not, shut down the
operating systems and turn off all of the blade servers, before you proceed. (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.)
