Information LED panel
The information LED panel on the front of the server
contains the following status lights.
- System Power Light: When this green light is on,
system power is present in the server. When this
light flashes, the server is in standby mode (the
system power supply is turned off and ac current is
present). When this light is off, either a power
supply, ac power, or a light has failed.
-Attention- If this
light is off, it does not mean there is no
electrical current present in the server. The
light might be burned out. To remove all
electrical current from the server, you must
unplug the server power cords from the
electrical outlets.
- System POST Complete Light: This green light is
on when the power-on self-test (POST) completes without any errors.
- SCSI Hard Disk Drive Activity Light: This green
light is on when there is activity on a hard disk drive.
- Processor Activity Lights: These green lights
indicate activity on each of the installed microprocessors.
- System Error Light: This amber light is on when a
system error occurs. A light on the diagnostics LED
panel will also be on to further isolate the error.
(For more information, see 'Status LEDs'.)
- Ethernet Transmit/Receive Activity Light: When
this green light is on, there is transmit or receive
activity to or from the server.
- Ethernet Link Status Light: When this green light
is on, there is an active connection on the Ethernet port.
- Ethernet Speed 100 Mbps: When this green light
is on, the Ethernet speed is 100 Mbps. When this
