Front Panel System Status LED Indicators
Non-Critical Condition
•Temperature, voltage, or fan non‐critical threshold crossing.
•Chassis intrusion.
•Satellite controller sends a non‐critical state, via the Set Fault Indication command, to the BMC.
•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.
