Installation guide

C.2 Conversion Procedure

Install the 70-inch DSSI cables (BC21R–5L) where necessary to complete the

bus connections to the Sx300 I/O panel:

1. Connect one end of the 70-inch DSSI cable to the DSSI connector on the

rear of the Sx72 storage enclosure or magazine tape subsystem.

2. Install the other end to the appropriate port on the Sx300 I/O panel. See

Figure C–7.

Connect the appropriate number of 108-inch DSSI cables (BC21Q–09) to all the

newly installed 70-inch DSSI cables on the Sx300 I/O panel.

Next, connect the other end of the 108-inch DSSI cables to the appropriate

DSSI connector on the system I/O panel.

Note

If you have not changed the KFMSA module DSSI ID numbers in

the other host system to 6, do so at this time. Do NOT attempt to

connect the 108-inch DSSI cables to this host system until the DSSI ID

numbers have been changed. Refer to the KFMSA Module Installation

and User Manual (EK–KFMSA–IM).

Refer to Table A–5 for cabling diagrams of the single-host and dual-host

conﬁgurations.

C.2.4 Labeling the Cables

This section describes the steps to label correctly the cables for the VAX 6000

series system, the Sx300 storage array, and its Sx72 storage enclosures and

tape magazine subsystems.

At this point, all steps in the previous sections must be complete.
