• Set Fault Indication command from system BIOS. The BIOS may use the Set Fault Indication
command to indicate additional, non‐critical status such as system memory or CPU
configuration changes.

Degraded Condition

• One or more processors are disabled by Fault Resilient Boot (FRB) or BIOS.
• BIOS has disabled or mapped out some of the system memory.

Activity LED

The Drive Activity LED on the front panel is used to indicate drive activity for either the SCSI
drives (SCSI configured system) or the ATA drives (ATA configured system). The server boards
SE7500WV2 and SE7501WV2 also provide a header giving access to this LED for add‐in IDE or
SCSI controllers.

Drive Activity/Fault LEDs

Next to each hard drive connector is an Activity/Fault LED. The LEDs are activated by the micro‐
controller and indicate either drive activity or a drive failure. The LEDs can be seen from the front
of the chassis by means of a light pipe mounted inside each hard drive carrier. During
initialization the micro‐controller flashes the LEDs for one second as part of POST.

Power Connector

The SCSI backplane provides power to the three drive bays, supporting up to three hard disk
drives or two hard disk drives, and the optional floppy/CD module. A 6‐pin power cable is routed
from the power distribution board and plugs into a 2 x 3 shrouded plastic PC power connector
(Molex: 39‐29‐9066) on the SCSI backplane. The following table shows the power connector
pinout.
