CAUTION: HP LSM drives are not customer installable or replaceable. Any servicing,
adjustment, maintenance or repair must be performed only by authorized HP service-
trained personnel.
Note to Customer Engineer: This installation may add new technology to the library
that older user’s guides do not address. Please remind the customer that the latest user

■Materials Included
■700 LVD SCSI COMPONENT INSTALLATION
If your library contains the second drive tower, you must first remove the MPM card before
installing the low voltage differential SCSI adapter card. If this does not apply to your
library, skip the following section and begin with MPW card installation, Section B.
A. MPM Removal
1. Be sure that the operator has the library and all drives offline.
2. Open the right front door.
3. Remove power from the library and drives by pushing the main circuit breaker down (off).
4. Using a 3/16 hex driver, remove the customer SCSI Y cable from the MPC card and lower
bulkhead. Discard the cable and the screwlocks that hold the connector to the lower
bulkhead (see Figure 1).

front and the two on the side and remove the cover (retain screws). Refer to Figure 2.

Figure 3. Grating under Electronic Module
WARNING:
THE CURRENT GRATING UNDER THE ELECTRONICS MODULE
ALLOWS SMALL ITEMS (NUMBER 4 SCREWS) TO FALL THROUGH
THE FAN ASSEMBLIES. LIKEWISE, THE GRATING ON TOP OF THE
POWER SUPPLIES (IDENTICAL) WOULD ALLOW SMALL ITEMS
DROPPED FROM ABOVE TO FALL THROUGH AND INTO THE DC
POWER SYSTEM. AT THIS TIME WE ADVISE PLACING A PIECE OF A
CARDBOARD OR AN ESD BAG UNDER THE MPC CONTROLLER
(BOTTOM OF THE ELECTRONICS MODULE) WHILE REMOVING THE
MPM AND WHILE ATTACHING THE CPCI CARD CAGE. BE SURE TO
REMOVE AFTER INSTALLATIONS ARE COMPLETE (SEE FIGURE 3).

6. Disconnect the P/J242 and P/J243 connectors from the MPM card. Disconnect cable from
bulkhead (as shown in Figure 4).
Figure 4. MPM Card Components
7. Using a 3/8-in. hex driver, remove the upper and lower MPM card nuts (see Figure 5).
8. Using a Torx T-10 driver, remove the center MPM card screw (see Figure 5).
9. Pull back slightly and turn the card to the left to remove the mounting plate from the two
studs.
10. Remove the MPM card and bracket. Set aside to be reinstalled in Section C.

B. MPW Card Installation
If you used Section A to remove the MPM card, skip to Step B5. Otherwise, begin with
Step 1.
1. Open the right front door.
2. Remove power from the library and drives by pushing the main circuit breaker down (off).
3. Remove the customer SCSI Y cable from the MPC card and lower bulkhead. Discard the
cable and the screwlocks that hold the connector to the lower bulkhead (see Figure 1).
4. Using a Torx T-15 driver, remove the four Electronics Module (EM) cover screws on the
front and the two on the side and remove the cover (retain screws). Refer to Figure 6.

WARNING:
THE CURRENT GRATING UNDER THE ELECTRONICS MODULE
ALLOWS SMALL ITEMS (NUMBER 4 SCREWS) TO FALL THROUGH
THE FAN ASSEMBLIES. LIKEWISE, THE GRATING ON TOP OF THE
POWER SUPPLIES (IDENTICAL) WOULD ALLOW SMALL ITEMS
DROPPED FROM ABOVE TO FALL THROUGH AND INTO THE DC
POWER SYSTEM. AT THIS TIME WE ADVISE PLACING A PIECE OF A
CARDBOARD OR AN ESD BAG UNDER THE MPC CONTROLLER
(BOTTOM OF THE ELECTRONICS MODULE) WHILE REMOVING THE
MPM AND WHILE ATTACHING THE CPCI CARD CAGE. BE SURE TO
REMOVE AFTER INSTALLATIONS ARE COMPLETE (SEE FIGURE 7).

CAUTION: Possible ESD damage. FOLLOW ESD PRECAUTIONS.
5. The card and its card cage are collectively termed “Compact Peripheral Component Inter-
connect”(CPCI). Open the CPCI package and remove the card from the anti-static bag.
6. Remove the MPW card from the CPCI. Loosen the captive screw using a Phillips screw-
driver (see Figure 8).

7. Disengage the latch.
8. Gently pull on the MPW card to release it from the MPV connector.
9. Slide the MPW card out of the card cage.
10. Place the MPW card on a static-free surface (you may use the anti-static bag).
CAUTION: Possible equipment damage: PUSH THE MPV CARD STRAIGHT
IN, BEING CAREFUL NOT TO DAMAGE THE CONNECTOR TO THE MPC
CARD.
11. Locate the MPV connector provided on the MPC card at J211. Gently mate the MPV card
with the MPC card connector (see Figure 9).
Figure 9. MPC Card Components
12. Install the three mounting screws (4-40 x 3/8) through the three cutouts in the card cage.
These screws go into the MPC card standoffs (see Figure 10).

CAUTION: Possible ESD damage. FOLLOW ESD PRECAUTIONS.
13. Obtain the MPW card. The MPW card is inserted into the CPCI card cage as described in
the next step.
14. Hold the card so that the card connector aligns with the MPV card connector (circuit side
out, components facing the MPC card).
15. Slide the MPW card onto the guide rail and gently push it until it mates with the MPV card
connector (see Figure 11).
Figure 11. MPW Card Install
16. Make sure the card latch engages (see Figure 8 for Steps 16 and 17).
17. Using a Phillips screwdriver, tighten the captive screw.
Note: If you removed an MPM card, skip to Step 20 otherwise, complete Steps 18
and 19 before proceeding.
18. Remove the ESD bag or cardboard from the grating.
19. Install the new EM cover, using six No. 6-32 x 3/8 screws on the front and two on the side.
NOTE:
ONLY THE LOWER SLOT IS
SUPPORTED AT THIS TIME.
BE SURE TO INSERT THE MPW
CARD INTO THAT SLOT.

Note: The library must be at the end of the SCSI bus as shown in Figure 12.
Devices can be host bus adapter, tape drives, other libraries, etc. Figure 12
depicts the actual physical location on the bus and not the SCSI ID.
Figure 12.
20. Connect the feed-through terminator to the connector on the MPW card.
21. Connect the male connector, on the single SCSI cable, to the connector on the feed-
through terminator (see Figure 13).
Figure 13. SCSI Cable Routing
22. Using a 3/16 hex driver, connect the two provided screwlocks through the left side of the
bulkhead into the SCSI cable connector (see Figure 14).
Note: Do not use original screwlocks removed in Step 3. Use the new
screwlocks provided in the kit.
23. Obtain the LVD SCSI icon and place it next to the connector on the bulkhead (see Figure
14).
24. Secure the cable in the strain reliefs.
