Status/Fault
Green/
Amber
This LED can assume different states (green, amber, steady, blinking) to indicate
critical, non-critical, or degraded server operation.
Steady green: Indicates the system is operating normally
Blinking green: Indicates the system is operating in a degraded condition.
Blinking amber: Indicates the system is in a non-critical condition.
Steady amber: Indicates the system is in a critical or non-recoverable condition.
Off: Indicates POST/system stop.
See “Front-Panel System Status LED” on page 2-18 for more details regarding
this LED.
Hard Disk Drive
Activity
Green The Drive Activity LED on the front panel is used to indicate drive activity from
the onboard SCSI controller. The server Main Board also provides a header,
giving access to this LED for add-in IDE or SCSI controllers.
Blinking green (random): Hard disk activity
Steady amber: Hard disk fault
Off: No disk activity nor fault condition (or power is off).
System ID Blue The blue System Identification LED is used to help identify a system for
servicing when it is installed within a high density rack or cabinet that is
populated with several other similar systems. The System ID LED is illuminated
when the system ID button, located on the front panel, is pressed. If activated
by the front panel pushbutton, the LED remains on until the pushbutton is
depressed again. The LED also illuminates when the server receives a remote
System Identify command from a remote management console. In this case, the
LED turns off after a timeout period. The timeout period is configurable, with a
default of 15 seconds. An additional blue System ID LED on the Main Board is
visible through the rear panel. It mirrors the operation of the front panel LED.
