Installing a BEB
Installing a BEB
To install a BEB, use the following procedure:
1. Make sure power is removed from each tape drive CRU that uses the BEB you are
installing.
2. Holding the BEB enclosure with two hands, align the captive wing nut and the
50-pin connector on the side of the BEB with the screw hole and the unterminated
SCSI port on the rear of the drive CRU. Plug the enclosure into the connector.
3. Push and tighten the wing nut to secure the BEB enclosure to the rear of the drive
CRU.
4. Remove the filler plug, if necessary, from the fiber-optic cable socket on top of the
BEB enclosure, and plug the fiber-optic cable connector into the socket.
5. Reapply power to the tape drive CRU by setting the AC power switch to the ON (|)
position.
6. Do the following for NonStop Himalaya K-series servers:
a. Use PUP to bring up the path to the tape drives. For example:
1> PUP
# UP $TAPE1
# UP $TAPE2
# EXIT
b. Run TMDS diagnostics to check the integrity of the modular tape subsystem.
You can use the TEST command to verify the operation of the BEB. For a
summary description, see The TMDS TAPE Subsystem (NonStop Himalaya
K-Series Servers) on page 5-1.
7. Do one of the following for NonStop Himalaya S-series servers:
a. Bring up the tape drive in either of these ways:
•
Use SCF to bring up the path to the tape drive. For example:
1> SCF
-> START $TAPE1
-> START $TAPE2
-> EXIT
•
Select the tape drive in the TSM Service Application and use the Up action
to bring up the tape drive itself.
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.
