Installing the Second Tape Drive

To install the second tape drive:

1. Remove the four 6-32 sems pan-head Phillips screws that hold the

blank panel in place in the drive caddy assembly; there are two on the

top of the assembly (Figure 4) and two on the bottom of the assembly.

2. Slide the blank panel out of the drive caddy assembly.

3. Disconnect the RS-422 cable that is located toward the front on the top

of the drive. Lift the cable clear of the cable clamps and set it aside.

4. Install the door lever on the flattened shaft at the bottom of the drive.

5. Slide the drive into the drive caddy assembly. Position the drive so

the threaded holes in the top and bottom of the drive are aligned with the

screw holes.

6. Install the four 6-32 sems pan-head Phillips screws that were removed in

Step 1.

7. Connect the unused connector on the power Y-cable to the drive just

installed.

8. Connect the unused connector on the SCSI cable to the drive just

installed.

9. Install the RS-422 cable supplied with the kit, sliding it under the

clamps so that the connector is adjacent to the connector on top of the

new drive.

10. Install the RS-422 cable removed in step 3 over the top of the new RS-

422 cable so that the connector is adjacent to the connector on top of the

original drive.

11. Connect the RS-422 cables to the connectors on the top of the drives,

through the holes in the top of the drive caddy assembly.

12. Replace the drive caddy assembly as described in “Removing and

Replacing the Drive Caddy Assembly.”
