This section describes the step-by-step procedure for cabling the magazine
tape ISE that you just installed to the existing DSSI bus configuration of the
DECarray.
Refer to Section 8.2.1 for instructions on cabling the magazine tape ISE in a
DECarray configured for single-system. Refer to Section 8.2.2 for instructions
on cabling the magazine tape ISE in a DECarray configured for a DSSI
VAXcluster system.
8.2.1 Single-System Configuration
Use the following procedures for cabling a magazine tape ISE in a DECarray
configured for single-system.
8.2.1.1 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. Disconnect the 70-inch DSSI cable (PN BC21Q–3F) connected to the
rightmost DSSI connector at the rear of the TF8x7 enclosure in position 1.
