Cabling and Configuration

Dual Shelf, Single Host

In this configuration two RAIDStation7 Ultra160 SCSI Storage Array shelves are

daisy chained together and connected to a single host system. The SCSI cable is

connected to the top I/O connector (when Storage Array is vertically oriented) of

Shelf 1, the other end of this cable is connected to the host system. The bottom I/

O connector of Shelf 1 is connected to the top I/O connector of Shelf 2 (see Fig-

ure 3-5). The First/Second Shelf ID switch on Shelf 1 should be set to “First” and

on Shelf 2 should be set to “Second”. The Single/Dual Host ID switch on both

shelves should be set to Single. The Dual VEM Enable/Disable ID switch should

be set to “2” on both shelves. No terminator is required because the bottom I/O

connector (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 automati-

cally. If there is no cable attached to this I/O connector, termination is turned on

automatically. In the example below, termination is turned off on the bottom I/O

connector of shelf 1 and is turned on on the bottom I/O connector of shelf 2.
