5.2 Cabling the SF7x in Storage Array Position

Note

Perform the next step if this is the only SF7x storage enclosure to

be installed on this particular DSSI bus. If not, then proceed to the

cabling instructions for the next SF7x storage enclosure that has been

installed.

8. Install a DSSI terminator in the leftmost DSSI connector at the rear of the

SF7x storage enclosure in SF4 and SF5.

9. Replace the Sx300 I/O panel to its original position and secure it by

tightening the two right captive screws.

5.2.1.5 Cabling SF3 or SF6

WARNING

Before performing the following steps, perform an orderly shutdown of

the system that the Sx300 storage array is connected to.

The following steps describe cabling for SF3 and SF6. Note that SF3 and SF6

operate in split-bus mode for a single-host conﬁguration.

1. Power down the SF7x storage enclosures SF1 and SF2 if you are installing

SF3. Power down the SF7x storage enclosures SF4 and SF5 if you are

installing SF6. 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 (part number BC21Q–3F) to the rightmost

DSSI connector on the rear of the SF7x storage enclosure SF3 and SF5.

3. Route this DSSI cable on the right side of the cabinet for SF3. For SF6,

route this cable above the SF7x storage enclosures in SF4 and SF5.

4. For SF3, connect this 42-inch DSSI cable to the leftmost DSSI connector at

the rear of the SF7x SF1. For SF6, connect this 42-inch DSSI cable to the

leftmost DSSI connector at the rear of the SF75.

5. Install a 42-inch DSSI cable (part number BC21Q–3F) to the leftmost DSSI

connector on the rear of the SF6 and SF3.

6. Route this DSSI cable on the left side of the cabinet SF3 and on the right

side of the cabinet for SF6
