Installing the SF7x Storage Enclosure in a DECarray Cabinet
6.6 Cabling the SF7x in a DECarray Cabinet
6.6.1.4 Cabling Position 4 or 7 (through bus)
CAUTION
Before performing the following steps, refer to the system documenta-
tion for the correct procedure to perform an orderly shutdown of the
system that the DECarray is connected to.
The following steps are for cabling positions 4 and 7:
1. At the rear of the DECarray cabinet, 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 3 (for
position 4) or port 4 (for position 7).
4. Install a 70-inch DSSI cable (PN BC21R–5L) in place of the panel blanks
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 into the rightmost DSSI
connector at the rear of the SF7x storage enclosure, in either position 4 or
7.
6. Route this DSSI cable under the cable retainers on the appropriate side of
the cabinet, left side for position 4, and right side for position 7.
7. Plug a 108-inch DSSI cable (PN BC21Q–09) into the port you just installed
in the previous steps (Figure 6–18). Tighten the retainer screws on the
108-inch DSSI cable with your fingers.
