2.1 Controller Module

The EP-2806-SA3 includes a U320 SCSI-to-SATA II Controller Module.

2.1.1 Controller Module Panel

The Controller Module has 6 major parts: Host Channel, UPS Port, RS-232 Port,

Ethernet Port, Alarm Mute Button, and a Hard Contact Relay. These parts are

described as follows:

1. Host Channel

The subsystem is equipped with 2 host channels (Host channel A and Host

channel B), with two 68-pin SCSI connectors at the rear of the subsystem, for

SCSI in and out.

2. Uninterrupted Power Supply (UPS) Port

The subsystem may come with an optional UPS port allowing you to connect a

UPS device. Connect the cable from the UPS device to the UPS port located at

the rear of the subsystem. This will automatically allow the subsystem to use

the functions and features of the UPS.
