IBM BladeCenter HS23, Installation And User Manual, Page: 34 / 98

Attention:
v
To maintain proper system cooling, do not operate the BladeCenter unit without
a blade server, expansion unit, or filler module installed in each blade server
bay.
v
When you remove the blade server, note the blade-server bay number.
Reinstalling a blade server into a different blade server bay from the one it was
removed from can have unintended consequences. Some configuration
information and update options are established according to blade-server bay
number; if you reinstall the blade server into a different bay, you might have to
reconfigure the blade server.
To remove the blade server, complete the following steps:
1. If the blade server is operating, shut down the operating system (see the
documentation for your operating system for more information).
2.
If the server is still on, press the power-control button for four seconds to turn
off the blade server (see “Turning off the blade server” on page 14 for more
information).
Attention: Wait at least 30 seconds, until the storage devices stops spinning,
before you proceed to the next step.
3. Open the two release handles as shown in the illustration. The blade server
moves out of the blade server bay approximately 0.6 cm (0.25 inch).
4. Pull the blade server out of the bay.
5. Place either a blade filler or another blade server in the blade server bay within
1 minute.
