Front Panel Alarm LEDs and Relays
C
Critical (amber)
When continuously lit, indicates the presence of a Critical System
Fault. A critical system fault is an error or event that is detected by the
system with a fatal impact to the system. In this case, the system
cannot continue to operate. An example could be the loss of a large
section of memory, or other corruption, that renders the system not
operational. The front panel critical alarm relay will be engaged.
D
Major (amber)
When continuously lit, indicates the presence of a Major System Fault.
A major system fault is an error or event that is detected by the system
that has discernable impact to system operation. In this case, the
system can continue to operate but in a “degraded” fashion (reduced
performance or loss of non-fatal feature reduction). An example could
be the loss of one of two mirrored disks. The front panel major alarm
relay will be engaged.
E
Minor (amber)
When continuously lit, indicates the presence of a Minor System Fault.
A minor system fault is an error or event that is detected by the system
but has little impact to actual system operation. An example would be
a correctable ECC error. The front panel minor alarm relay will be
engaged.
F
Power (amber)
When continuously lit, indicates the presence of a Power System
Fault. The front panel power alarm relay will be engaged.
Front Panel Status LEDs
G
Disk 1 Activity/Fault LED
(green/amber)
Indicates disk 1 SCSI hard drive activity when green, or a disk 1 SCSI
hard drive fault when amber
H
Disk 2 Activity/Fault LED
(green/amber)
Indicates disk 2 SCSI hard drive activity when green, or a disk 2 SCSI
hard drive fault when amber
I
Main power LED (green)
When continuously lit, indicates the presence of DC power in the
server. The LED goes out when the power is turned off or the power
source is disrupted.
