8.2 Cabling the Magazine Tape ISE
8.2.2.2 Cabling Position 6
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. If an TF8x7 storage enclosure is installed in position 2, take the disk ISEs
in position 2 off-line before you proceed. To do so, first take each ISE off-
line, then press all the drive dc power switches to the out position, and
then 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 2.
3. Pull the inner assembly of the magazine tape ISE out to the head cleaning
position (first mechanical stop).
4. Connect this 70-inch DSSI cable to the top DSSI connector on the rear of
the magazine tape ISE.
5. Route this DSSI cable under the cable retainers on the left side of the
cabinet.
6. Connect a 42-inch DSSI cable (PN BC21Q–3F) to the rightmost DSSI
connector at the rear of the TF8x7 in position 2 to the bottom DSSI
connector at the rear of the magazine tape ISE in position 6 (Figure 8–14).
7. Route this DSSI cable under the cable retainers on the left side of the
cabinet.
