WARNING
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 position 2 through 8 without a magazine
tape ISE.
1. At the rear of the DECarray, 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. Determine which ports you are using for the installation. Refer to
Table 6–4 to determine which proper ports for each storage enclosure
position.

for the enclosure you are installing.
5. Install two 70-inch DSSI cables (PN BC21R–5L) in place of the blanks you
just removed in the previous step. Secure the DSSI cable to the I/O panel
