Installation

Before you begin the installation procedure, remove the bus continuity card
from the option storage slot into which you intend to install the disc. Figure 6
shows the location of the bus continuity cards.

To install an RRD43-MX disc drive in your system, perform the following steps:

1. Slide the RRD43-MX mounting bracket assembly into the option storage
slot and push until the connector on the SCSI paddle card on the bracket
engages securely into the backplane. Secure the drive in place by
tightening the two captive screws (Figure 2). Do not over-tighten the
screws. It is normal for there to be a slight gap between the bracket and
chassis.

2. Attach the SCSI ID cable to the OCP connector on the bezel assembly
(Figure 2).

3. Insert the tabs on the bottom of the bezel into the slots on the storage slot
(Figure 2).

4. Push in the top of the bezel, and tighten the Phillips screw (Figure 2).

5. Install a SCSI ID plug to the front of the bezel, making sure that the SCSI
ID number is not used by another device.

To add an RRD43-MY disc drive to your system, perform the following steps:

1. Remove the mounting assembly by reversing steps 1 through 5 above.

2. Connect the SCSI ID cable to the back of the drive (Figure 1), making sure
that the jumper is installed over the pins marked PARITY.

3. Slide the drive into the mounting assembly.

4. Attach the SCSI and power cables to the drive. Figure 1 shows the location
of the connectors.

5. Secure the drive into the mounting assembly with the four mounting
screws provided. Two screws attach to the top of the assembly, and two
screws attach to the bottom of the assembly (Figure 3 shows the top of the
assembly). Make sure that the top front screw goes through the grounding
strip shown in the figure.

Failure to connect the grounding strip could result in data errors.

6. Remove the blank panel from the bezel (Figure 4).

7. Remove the blank flat plug(s) from the bezel (Figure 5).

8. Return the OCP connector board to the bezel.

9. Install SCSI ID plugs on the front of the bezel. Each drive must have an
unique SCSI ID number. If one of the drives was installed prior to this
add-on procedure, make sure that you use the same SCSI ID number that
was used previously. The bezel is marked to show the corresponding SCSI
ID plug to each slot.

10. Slide the mounting bracket assembly into the option storage slot and
push until the SCSI paddle card on the bracket engages securely into the
backplane. Secure the drive in place by tightening the two captive screws
(Figure 2). Do not over-tighten the screws. It is normal for there to be a
slight gap between the bracket and chassis.

11. Attach each SCSI ID cable into the appropriate connector on the OCP
connector board on the bezel (Figure 2). Make sure that the cable from the
RRD43-MX drive is returned to the connector in which it was originally
installed.

12. Insert the tabs on the bottom of the bezel into the slots on the storage slot
(Figure 2).

13. Push in the top of the bezel, and tighten the Phillips screw (Figure 2).

When either the J6 or J7 backplane connector is not used, insert a bus
