Cabling and Configuration

Connecting to a Host System

This section describes the procedure for connecting the RAIDStation7 Ultra160 
SCSI Storage Array to a single or dual host.

NOTE: This section describes the connectors on the RAIDStation7 Ultra160 
SCSI Storage Array, it does not describe the connectors on the host. For 
information relating to the host, refer to the host systems User Guide.

Single Shelf, Single Host

In this configuration a single RAIDStation7 Ultra160 SCSI Storage Array shelf is 
connected to a single host system. The SCSI cable is connected to the top I/O 
connector (when Storage Array is vertically oriented) on the rear of the Storage 
Array. The other end of this cable is connected to the host system (see Figure 3-
4). The First/Second shelf ID switch should be set to “First”. The Single/Dual 
host ID switch should be set to “1”. The Dual VEM Enable/Disable ID switch 
should be set to “0 or 1”. No terminator is required because the bottom I/O con-
nector (closest to power supplies) of each shelf has in-built termination. If there is 
a cable attached to this I/O connector, termination is turned off automatically. If 
there is no cable attached to this I/O connector, termination is turned on automat-
ically.
