Installation

Connectors, Jumpers and LEDs

There are two external Ultra 160 SCSI channels (connectors) supported on the controller as shown in Figure 2-1.

SCSI jumpers should normally be set to their default settings, no adjustments are needed. Default jumper locations are shown in Figure 2-2and are described in Table 2-1.

The AcceleRAID 352 controller has one LED on the front side as shown in Figure 2-3and described in Table 2-2.

There are four LEDs on the back of the controller that are mode indicators while the controller is running, shown in Figure 2-4and described in Table 2-3.

The LEDs indicate single ended, LVD, and FAIL modes.

In addition there is a six-pin header. Figure 2-4identifies the location of each pin. Table 2-4identifies the function of each pin: 3.3V power, Channel 0 and Channel 1 SCSI activity, cache dirty status and, a ground pin.

When you have checked the termination requirements, completed the connections of your desired SCSI devices and other possible devices such as a CD-ROM drive or a tape drive, close your system with the cover.
