z
Power Fail: Indicates a power supply module has failed. This should
be accompanied by an audible alarm. A backup power supply module will
take the load and keep the system running but the failed module will need to
be replaced. Refer to Chapter 6 for details on replacing the power supply.
This LED should be off when the system is operating normally.
3-4 SCSI Drive LEDs
Each SCSI drive carrier has two LEDs.
z
Green: When illuminated, the green LED on the front of the SCSI drive
carrier indicates drive activity. A connection to the SCSI SCA backplane
enables this LED to blink on and off when that particular drive is being
accessed.
z
Red: A SAF-TE compliant backplane is needed to activate the red
LEDs, which indicate a drive failure. Please refer to Chapter 6 for instruc-
tions on replacing failed SCSI drives.
3-5 LAN (Ethernet) Port LEDs
The LAN Ethernet port(s) (located beside the VGA port) each have a yellow and
a green LED. The yellow (left) LED indicates activity while the other (right) LED
may be green, orange or off to indicate the speed of the connection. See the
tables below for the functions associated with these LEDs.
