Removing the blade server from the BladeCenter unit
The following illustration shows how to remove a blade server from a BladeCenter
unit. The appearance of your BladeCenter unit might be different, see the
documentation for your BladeCenter unit for additional information.
Release handles

Attention:
v
To maintain proper system cooling, do not operate the BladeCenter unit without a
blade server, expansion unit, or blade filler installed in each blade bay.
v When you remove the blade server, note the bay number. Reinstalling a blade
server into a different bay from the one it was removed from could have
unintended consequences. Some configuration information and update options
are established according to bay number; if you reinstall the blade server into a
different bay, you might need 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; then, press the
power-control button (behind the blade server control panel door) to turn off the
blade server (see “Turning off the blade server” on page 11 for more
information).
Attention: Wait at least 30 seconds, until the hard disk drives stop spinning,
before you proceed to the next step.
2. (BladeCenter T unit only) Remove the bezel assembly on the BladeCenter T
unit. For detailed instructions for removing the bezel assembly, see the
Installation and User’s Guide that comes with the BladeCenter T unit.
3. Open the two release handles as shown in the illustration. The blade server
moves out of the 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 in the bay within 1 minute.
