Removing a BEB
Removing a BEB
If you determine that a BEB has failed, order a new BEB and use the following
procedure to remove the defective BEB.
1. Shut down the application software that uses the tape drive. If the BEB serves two
drives, you must bring down both drives.
2. Do the following for NonStop Himalaya K-series servers: Use PUP to bring down
the path to the tape drives. For example:
1> PUP
# DOWN $TAPE1
# DOWN $TAPE2
# EXIT
3. Do one of the following for NonStop Himalaya S-series servers:
•
Use SCF to bring down the path to the tape drive. For example:
1> SCF
-> STOP $TAPE1
-> STOP $TAPE2
-> EXIT
•
Select the tape drive in the TSM Service Application and use the Down action
to bring down the tape drive itself.
4. Open 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 that uses the BEB 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. Remove the fiber-optic cable connector from the socket on top of the BEB
enclosure by squeezing the latches and pulling straight up. (See Figure 3-15 on
page 3-28.)
7. Loosen the captive wing nut that holds the BEB enclosure to the rear of the drive
CRU. One half-turn is enough to loosen this nut.
8. Grasping the BEB enclosure firmly with two hands, pull the BEB enclosure straight
off the rear of the drive CRU.
Caution. The BEB contains static-sensitive components. Be sure to touch a grounded object
before touching the BEB. Compaq recommends that you use an electrostatic discharge (ESD)
protection kit to protect electronic and static-sensitive components such as the BEB from
electrostatic discharge. For ESD guidelines, see the Himalaya S-Series Hardware Support
Guide.
