Practice 450-1011-201
(7) Push one end of the SASI cable onto the 50-pin connector at the rear of the 80
Megabyte Mass Storage SRU. The connector is keyed so that it connects only
one way.
(8) Tighten the two screws on the connector with a flat-blade screwdriver.
(9) Route the cable down the rear of the cabinet, out beneath the door and into the
cabinet housing the 350 Mbyte Mass Storage SRU. Dress the cable as
necessary.
(10) Push the free end of the cable onto the right-most (as viewed from the rear)
50-pin connector on the rear panel of the 350 Mbyte Mass Storage SRU. The
connector is keyed so that it connects only one way.
SASI Cabling for the 350 Megabyte Mass Storage SRU
This procedure is optional and is used only if the system includes the optional 350
Mbyte Mass Storage SRU in addition to the 80 Megabyte Storage SRU. If you are
upgrading an existing system, you must reorganize the SRUs as shown in Fig. 8-4.
- CAUTION -
Do not power up the system until the Primary Processor and Mass Storage
SRU have been interconnected. If disconnecting this cable, power down the
system first.
(1) If the rear door of the cabinet is closed, open it to access the rear panels of the
SRUs. The Primary Processor should be located directly above the 350 Mbyte
Mass Storage SRU. (You can check their locations from the front of the cabinet,
if you wish, as each SRU is labeled on its front panel. Also, the product code is
located on a label on the rear panel of each SRU.)
(2) Locate the 609 mm (2 ft) SASI cable, which is typically shipped in the same
packing carton as the 80 Megabyte Mass Storage SRU.
(3) Push one end of the SASI cable onto the 50-pin connector at the upper left of
the Primary Processor's rear panel, as viewed from the rear. The connector is
keyed so that it connects only one way.
(4) Tighten the two screws on the connector with a flat-blade screwdriver.
(5) Push the other end of the cable onto the left-most (as viewed from the rear)
50-pin connector on the rear panel of the Mass Storage SRU. The connector is
keyed so that it connects only one way.
