5.2 Cabling the SF7x in Storage Array Position

The following steps are for cabling SF2 without a magazine tape subsystem

(TF2):

1. At the rear of the Sx300 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. Install a 70-inch DSSI cable (part number BC21R-5L).Secure this cable to

the I/O panel with two Phillips screws. See Figure 5–11.

4. Plug the other end of this cable into the rightmost DSSI connector at the

rear of the SF7x storage enclosure (SF2).

5. Route this DSSI cable under on the left side of the cabinet.

6. Plug a 108-inch DSSI cable (part number BC21Q–09) into the DSSI cable

you just installed in port 2. Tighten the retainer screws with your ﬁngers.

Note

The following step assumes that no SF7x storage enclosures are

installed internally in the system cabinet. If there are SF7x storage

enclosures installed in the system cabinet, then one of the KFMSA

modules installed in the system XMI backplane must be connected to

those SF7x storage enclosures. Do NOT use this KFMSA module or its

DSSI connections to connect the system to the Sx300 storage array.

7. Plug the other end of the 108-inch DSSI cable into the appropriate port on

the system I/O panel at the rear of the system cabinet. To determine which

of the two DSSI connectors on the system I/O panel to connect to:

a. Locate the DSSI connectors on the system I/O panel labeled BLUE and

RED.
