Installing an Expander Cabinet
3-33
1.
Attach one end of the DSSI cable (BC21Q-06 or BC21Q-09) to the XMI
PIU bulkhead connector in the rear of the system cabinet (see Figure
3-16). If necessary, install a terminator plug to properly terminate this
end of the DSSI cable.
2.
Route the DSSI cable through the upper cable trough on the right rear
of the system cabinet to the front of the expander cabinet. Now route
the DSSI cable to the topmost disk brick.
3.
Attach the end of the DSSI cable to the left hand connector of the disk
brick in the top of the disk PIU. If only one disk brick is present, at-
tach a terminator plug to the other connector (see Figure 3-17).
4.
If two or more disk bricks are present, use short jumper cables
(BC21Q-01) to daisy-chain the disk bricks (see Figure 3-17) on a single
channel. Install the jumpers and terminator as shown in Figure 3-17.
