Installing the Magazine Tape ISE in a DECarray Cabinet
8.2 Cabling the Magazine Tape ISE
8.2.2 DSSI VAXcluster Configuration
Use the following procedures for cabling a magazine tape ISE in a DECarray
configured for DSSI VAXcluster system.
8.2.2.1 Cabling Position 5
CAUTION
Before performing the following steps, refer to the system documenta-
tion for the correct steps to perform an orderly shutdown of the system
that the DECarray is connected to.
1. Take the disk ISEs in position 1 off-line before you proceed. To do so, first
take each ISE off-line by pressing the Ready buttons. Then press all the
drive dc power switches to the out position. Last, turn off the ac power at
the rear of the storage enclosure.
CAUTION
Use care not to disturb or damage power cords and DSSI cables that
are already connected to the DSSI I/O panel.
2. Pull the inner assembly of the magazine tape ISE out to the head cleaning
position (first mechanical stop).
3. Disconnect the 70-inch DSSI cable (PN BC21R–5L) connected to the
rightmost DSSI connector at the rear of the SF7x enclosure in position 1.
4. Connect the 70-inch DSSI cable removed from the SF7x storage enclosure
to the top DSSI connector on the rear of the magazine tape ISE.
5. Route this DSSI cable under the cable retainers on the right side of the
cabinet.
6. Connect a 42-inch DSSI cable (PN BC21Q–3F) to the rightmost DSSI
connector at the rear of the SF7x in position 1 to the bottom DSSI
connector at the rear of the magazine tape ISE in position 5 (Figure 8–13).
7. Route this DSSI cable under the cable retainers on the right side of the
cabinet.
