5. Find the next KFMSA module installed in the XMI backplane of the
system. It will be 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.
If these connectors are not labeled, label them now with the small colored
labels in the SF Family Label Booklet.
