Installing the SF7x Storage Enclosure in a DECarray Cabinet
6.6 Cabling the SF7x in a DECarray Cabinet
6.6.1.5 Cabling Position 3 or 8 (Split-Bus)
CAUTION
Before performing the following steps, perform an orderly shutdown of
the system that the DECarray is connected to.
The following steps describe cabling for positions 3 and 8. Note that positions
3 and 8 operate in split-bus mode for a single-system configuration.
1. Power down the SF7x storage enclosures in position 1 and 2 if you are
installing in position 3. Power down the SF7x storage enclosures in
position 4 and 7 if you are installing in position 8.
To power down an enclosure, first press the Ready button for each ISE,
then press each drive dc power switch (one at a time), and finally at the
rear of the enclosure press the ac power switch to 0.
2. Install a 42-inch DSSI cable (PN BC21Q–3F) to the rightmost DSSI
connector on the rear of the SF7x storage enclosure in position 3 or 8
(Figure 6–19).
3. Route this DSSI cable under the cable retainers on the right side of the
cabinet for position 3.
For position 8, route this cable above the SF7x storage enclosures in
positions 7 and 8.
4. For position 3, connect this 42-inch DSSI cable to the leftmost DSSI
connector at the rear of the SF7x in position 1.
For position 8, connect this 42-inch DSSI cable to the leftmost DSSI
connector at the rear of the SF7x in position 7.
5. Install a 42-inch DSSI cable (PN BC21Q–3F) to the leftmost DSSI
connector on the rear of the SF7x in position 3 or 8.
6. Route this DSSI cable under the cable retainers on the right side of the
cabinet for position 3 and on the left side of the cabinet for position 8.
7. For position 3, connect this 42-inch DSSI cable to the leftmost DSSI
connector at the rear of the SF7x in position 2. For position 8, connect this
42-inch DSSI cable to the leftmost DSSI connector at the rear of the SF7x
in position 4.
CAUTION
Do not apply power to the storage enclosure at this time.
