Connectors, Jumpers and LEDs

2-6 eXtremeRAID 3000 Installation Guide

Connectors, Jumpers and LEDs

There are two Fibre Loop connectors and one internal Ultra2 SCSI channel

connector supported on the controller as shown in Figure 2-1.

SCSI jumpers should normally be set to their default settings and no

adjustments are needed. Default jumper locations are shown in Figure 2-2.

Jumper descriptions are described in Table 2-1.

The controller has eight LEDs that are active indicators while the controller

is running. The LEDs indicate SCSI activity, single ended mode, Fibre

activity, LVD mode, host activity, cache dirty status, diagnostic status, and

Fibre channel 1 activity. The eXtremeRAID 3000 controller LED locations

and meanings are shown in Figure 2-3.

When you have checked the SCSI channel termination requirements, and

completed the connections of internal SCSI devices and other possible

devices such as a CD-ROM drive or a tape drive, cover your system and

proceed to the Fibre channel connections.

There are two external Fibre loops (channels) supported on the controller as

shown in Figure 2-10. Fibre connections will be discussed after the SCSI

information.
