C–12 Converting a Single-Host Conﬁguration to a Dual-Host Conﬁguration

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

the bus connections to the SF200 I/O panel. To do so:

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

located on the rear of the SF72 storage enclosure or magazine tape

subsystem.

2. Install the other end to the appropriate port on the SF200 I/O panel.

Refer to Figure C–5.

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

all the newly installed 70-inch DSSI cables on the SF200 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 chnaged 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 Onwer’s Manual.

Refer to Appendix A for cabling diagrams of both the single-host and

dual-host conﬁgurations.
