5–56 Installing the SF72 Storage Enclosure in an SF200 Storage Array

5.2.2.3 Cabling Position 2

WARNING

Before performing the following steps, refer to the system

documentation for the correct steps to perform an orderly

shutdown of the system that the storage array is connected to.

The SF72 storage enclosure installed in position 2 of the storage array has

two possible cabling conﬁgurations. The difference depends on whether a

magazine tape subsystem is installed in position 6 of the SF200 storage

array.

The following steps are for cabling position 2 without a magazine tape

subsystem in position 6:

1. At the rear of the storage array, locate the DSSI I/O panel at the

bottom. Use a 3/16-inch ﬂatblade screwdriver to loosen the two

captive screws at the right of the panel.

2. Swing open and remove the panel from the cabinet frame.

CAUTION

Use care not to disturb or damage power cords and DSSI

cables that are already connected to the DSSI I/O panel.

3. Remove the two Phillips screws that hold the panel blank in port 2

and port 10.

4. Install two 70-inch DSSI cables (part number BC21R–5L) in place of

the panel blanks you just removed in the previous step. Secure this

cable to the I/O panel with the two Phillips screws removed from the

blank panel.

5. Plug the other end of the 70-inch DSSI cable from port 2 into the

rightmost DSSI connector at the rear of the SF72.

6. Route this DSSI cable under the cable retainers on the right side of

the cabinet.

7. Plug the other end of the 70-inch DSSI cable from port 10 into the

leftmost DSSI connector at the rear of the SF72 (Figure 5–25).

8. Route this DSSI cable under the cable retainers on the left side of the

cabinet.

9. Plug two 108-inch DSSI cables (part number BC21Q–09) into ports 2

and 10 (Figure 5–25). Tighten the retainer screws with your ﬁngers.
