2. Swing open 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). Plug the other end
of this cable into the rightmost DSSI connector at the rear of SF4.
4. Install a 70-inch DSSI cable (part number BC21R–5L) in place of the panel
blank you just removed in the previous step. Plug the other end of this
cable into the leftmost DSSI connector at the rear of the SF4.
5. For the cable to port 4, route the DSSI cable on the right side. For the
cable to port 8, route the DSSI cable under the cable retainer on the left
side.
6. Plug two 108-inch DSSI cables (part number BC21Q–09) into ports 4 and 8.
Tighten the retainer screws on the 108-inch DSSI cables 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 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 YELLOW
and GREEN.
b. From port 4 on the Sx300 I/O panel, connect the 108-inch DSSI cable to
the right DSSI connector (GREEN) of the first system I/O panel.
c. From port 10 on the Sx300 I/O panel, connect the 108-inch DSSI cable
to the right DSSI connector (GREEN) of the second system I/O panel.
