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

■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).

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.

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).

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.
