6.6 Cabling the SF7x in a DECarray Cabinet
5. Find the next KFMSA module installed in the XMI backplane of the
system. It is the next KFMSA module after the KFMSA module in the
lowest numbered slot of the XMI backplane.
6. Follow the cabling from the backplane to the system I/O panel.
7. While viewing the front of the I/O panel, note that the DSSI connector
on the left is KFMSA DSSI bus 2 and the DSSI connector on the right is
KFMSA DSSI bus 1. These connectors should be labeled YELLOW for bus
1 and GREEN for bus 2.
If these connectors are not labeled, label them now with the small colored
labels in the SF Family Label Booklet.
For the single-system configuration, use the BLUE, RED, YELLOW, and
GREEN labels only.

magazine tape ISE in position 5, or for cabling a storage enclosure in position
2 with a magazine tape ISE in position 6.
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 ISE.
2. Remove the DSSI terminator from the bottom DSSI connector on the rear
of the magazine tape ISE.
