Removing a Tape Drive CRU
4. Remove the rear bezel door of the tape drive module. See Opening and
Removing the Rear Bezel Door on page 3-23.
5. Remove power from each tape drive CRU by setting the AC power switch at the
rear of each drive CRU to the OFF (0) position. (See Figure 3-24 on page 3-39.)
6. Unplug the AC power cord from the rear of the drive CRU to be removed. Leave
the AC power cord in place for use with the replacement CRU.
7. Perform one of the actions in the following table:
Leave the cables in place for attachment to the replacement drive CRU.
8. If the drive CRU to be removed has a BEB, remove the BEB using the procedure
in Replacing a BEB on page 6-2.
9. (NonStop Himalaya K-series servers only) If a daisy-chain cable links the drive
CRU to be removed to a second drive CRU in the module, disconnect the cable
from the drive CRU that you are removing.
Prepare to pull the drive CRU out of the module. With a person on each side of the
drive CRU ready to support the drive CRU, press down on the locking clip and pull on
the pull-out handle at the bottom of the drive CRU. Support the underside of the drive
CRU as it emerges from the module. Do not try to support the CRU by the pull-out
handle (see Figure 6-1).
