5–54 Installing the SF72 Storage Enclosure in an SF200 Storage Array
5.2.2.2 Cabling Position 1
WARNING
Before performing the following steps, refer to the system
documentation for the correct steps to perform an orderly
shutdown of the systems that the storage array is connected
to.
The following steps are for cabling position 1 with a magazine tape
subsystem in position 5:
CAUTION
Use care not to disturb or damage power cords and DSSI
cables that are already connected to the DSSI I/O panel.
1. Tighten the shipping screw in the rear, upper right corner, of the
magazine tape subsystem in position 5.
2. Disconnect the 70-inch DSSI cable (part number BC21R–5L) from the
bottom DSSI connector of the magazine tape subsystem in position 5.
3. Reconnect this 70-inch DSSI cable to the leftmost DSSI connector on
the rear of the SF72 in position 1 (Figure 5–24).
4. Install a 42-inch DSSI cable (part number BC21Q–3F) in the bottom
DSSI connector of the magazine tape subsystem in position 5.
5. Loosen the shipping screw in the rear, upper right corner, of the
magazine tape subsystem in position 5.
6. Pull the inner assembly of the magazine tape subsystem in position
5 out to its head-cleaning position. Cabling the magazine tape
subsystem with the inner assembly pulled out to the head-cleaning
position ensures that the correct cable slack will be provided when the
inner assembly is pushed back into the extrusion tube.
7. Connect the 42-inch DSSI cable from the bottom DSSI connector of
the magazine tape subsystem in position 5 to the rightmost DSSI
connector of the SF72 in position 1 (Figure 5–24).
8. Route this DSSI cable under the cable retainers on the right side of
the cabinet.
9. Push the magazine tape subsystem in position 5 back into the
extrusion tube.
CAUTION
Do not apply power to the SF72 enclosure at this time.
