Chapter 3. Cabling the storage subsystem

After the storage subsystem is installed in its permanent location, you must cable it
to hosts, drives, and other external devices, depending on your hardware
configuration.
This chapter addresses the following cabling and configuration topics:

Enclosure ID settings

The enclosure ID, comprised of two seven-segment numbers, is located on the
back of each controller next to the indicator lights. It provides a unique identifier for
each enclosure in the DS4000 storage subsystem configuration.
The controller automatically sets the enclosure ID number. You can change the
setting through the storage management software if necessary. Both controller
enclosure ID numbers are identical under normal operating conditions.
The allowable ranges for enclosure ID settings are 0-99. Do not set the enclosure
ID to 00 or any number less than 80. The DS4200 Express enclosure ID is normally
set to a value of 85 at the factory.
Figure 22 shows the enclosure ID on the DS4200 Express.
