6.2 Cabling the Subsystem in Sx300 Storage Array Position

6.2.1 Single-Host Conﬁguration

Use the following procedures for cabling a magazine tape subsystem in an

existing Sx300 storage array conﬁgured for single-host.

6.2.1.1 Cabling TF1

WARNING

Before performing the following steps, refer to the system documenta-

tion for the correct steps to perform an orderly shutdown of the system

which the Sx300 storage array is connected to.

The following steps are for cabling a magazine tape subsystem in an existing

Sx300 storage array conﬁgured for single-host:

1. Take the disk ISEs SF1 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. Lastly, 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 (part number BC21Q–3F) connected to

the rightmost DSSI connector at the rear of the SF1.

3. Connect the 70-inch DSSI cable removed from SF1 (Figure 6–7) and

connect it to the top DSSI connector on the rear of the magazine tape

subsystem. Route this DSSI cable on the right side of the cabinet.

4. Connect a 42-inch DSSI cable (part number BC21Q–3F) to the rightmost

DSSI connector at the rear of the SF2 and to the bottom DSSI connector

at the rear of the magazine tape subsystem TF1. Route this DSSI cable on

the right side of the cabinet.

CAUTION

Do not power up the magazine tape subsystem or the SF72 storage

enclosure at this time.
