Installation guide

5.2 Cabling the SF7x in Storage Array Position
1. Open the system I/O panel on the system by removing the screws that
secure the I/O panel to the system chassis. Let the panel swing down to its
rest position.
2. Find the first KFMSA module installed in the XMI backplane of the
system. It will be the KFMSA module in the lowest numbered slot of the
XMI backplane.
3. Follow the cabling from the backplane to the system I/O panel.
4. 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 BLUE for bus 1
and RED for bus 2.
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. 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 (part number 36–32882–01).
For the single-host configuration, use the BLUE, RED, YELLOW, and GREEN
labels only.
