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.
