5.2 Cabling the SF7x in Storage Array Position
2. Swing open the panel.
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 two 70-inch DSSI cables (part number BC21R–5L). Secure this cable
to the I/O panel with two Phillips screws .
4. Plug the other end of the 70-inch DSSI cable from port 2 into the rightmost
DSSI connector at the rear of the SF7x.
5. Route this DSSI cable on the right side of the cabinet.
6. Plug the other end of the 70-inch DSSI cable from port 8 into the leftmost
DSSI connector at the rear of the SF7x. See Figure 5–15.
7. Route this DSSI cable on the left side of the cabinet.
8. Plug two 108-inch DSSI cables (part number BC21Q–09) into ports 2 and 8
(see Figure 5–15). 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.
9. Plug the other end of the 108-inch DSSI cables into the appropriate ports
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.
b. From port 2 on the Sx300 I/O panel, connect the 108-inch DSSI cable to
the right DSSI connector (RED) of the first system I/O panel.
