Front Panel Alarm LEDs and Relays
E
Critical (amber or red)
The Critical alarm LED can be either amber (default) or red (set with an
FRUSDR update). When continuously lit, indicates a Critical System Fault
occurred. A critical system fault is an error or event that has a fatal
system impact. In this case, the system cannot continue to operate. An
example is the loss of a large section of memory, or other corruption. The
front panel critical alarm relay is engaged.
F
Major (amber or red)
The Major alarm LED can be either amber (default) or red (set with an
FRUSDR update). When continuously lit, indicates a Major System Fault
occurred. A major system fault is an error or event that has discernible
impact to the system operation. In this case, the system can continue to
operate, but in a degraded fashion (reduce performance or with the loss
of non-fatal features). An example is the loss of a mirrored disk. The front
panel major alarm relay is engaged.
G
Minor (amber)
When continuously lit, indicates a Minor System Fault occurred. A minor
system fault typically has little impact to the system operation. An
example is a correctable ECC error. The front panel minor alarm relay is
engaged.
H
Power (amber)
When continuously lit, indicates a Power System Fault occurred. The front
panel power alarm relay is engaged.
Front Panel Status LEDs
I
System ID LED (white)
Indicates system identity
This LED can be toggled remotely or by front panel ID switch
J
NIC activity LED (green)
Indicates NIC activity when lit
K
Main power LED (green)
When continuously lit, indicates the presence of power supply DC output
power in the server. The LED turns off when the main output power from
the power supply is turned off or if the power source is disrupted.
L
HDD activity / fault LED
(green / amber)
Indicates HDD activity when green or an HDD fault when amber. This is an
aggregated indication for all hard drives in the system (up to six). Each
hard disk contains its own activity and fault indicators.
