2. Shut down the operating systems and turn off any blade servers in the
BladeCenter HT unit. See the documentation that comes with the blade server
for detailed instructions.

from the BladeCenter HT unit” on page 11).
4. Disconnect the cables from the modules in the rear of the BladeCenter HT
unit.
5. Remove any of the following modules that are installed in the rear of the
BladeCenter HT unit:
v Fan modules (see “Removing a fan module” on page 83).
