Installation guide

Installing the SF72 Storage Enclosure in an SF200 Storage Array 5–35
5.2.1 Single-Host Configuration
Use the following procedures for cabling an SF72 storage enclosure in an
existing SF200 storage array configured for single-host.
The following procedures assume that all devices installed previous to a
new installation of an SF72 storage enclosure are cabled in the single-host
configuration.
5.2.1.1 Identifying DSSI Connectors on the System I/O Panel
The following procedure explains how to locate and identify the DSSI
connections on the VAX 6000 system I/O panel.
WARNING
Before performing the following steps, refer to the system
documentation for the correct steps to perform an orderly
shutdown of the systems that the SF200 storage array is
connected to.
NOTE
This procedure assumes that no SF72 storage enclosures are
installed internally in the system cabinet. If SF72 storage
enclosures are in the system cabinet, then one of the KFMSA
modules in the system XMI backplane must be connected to those
SF72 storage enclosures. DO NOT USE this KFMSA module or
its DSSI connections to connect the system to the SF200 storage
array. DO NOT COUNT this KFMSA module in the following steps.
1. Open the system I/O panel on the system by removing the six 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.
