Jumper Settings

RAID systems, which use the Mylex RAID controller, do not use any jumpers on these headers.
The spin-up delay and SCSI ID settings are controlled by the RAID controller and SCSI
backplane, respectively.

Removable Disk Drive LEDs

Light-emitting diodes (LEDs) D1 through D8 are visual activity indicators for the removable disk
drives installed in the disk drive bay. The LEDs are grouped in pairs above each slot in the disk
drive bay, and are visible behind the disk drive bay door.
The right LED above each removable disk drive flashes to show disk activity.
The left LED functions only when an optional SCSI Accessible Fault-Tolerant Enclosure
(SAF-TE) card is installed, and when the backplane is connected to a SAF-TE compliant SCSI
controller or RAID controller.
