Information LED panel
The following illustration shows the status lights on the Information LED panel.
System power light:
When this green light is on, 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, the power subsystem, the ac
power, or a light has failed.
Attention: If the system power 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 or from
the uninterruptible power device.
POST-complete light:
This green light is on when the power-on self-test (POST) completes without
any errors.
Hard disk drive activity light:
This green light flickers when there is activity on a hard disk drive.
Information light:
When this amber light is on, the server power supplies are nonredundant or
some other noncritical event has occurred. The event is recorded in the Event
log. See “Choices available from the Configuration/Setup main menu” on
page 46. A light on the diagnostic panel may also be on; see “Diagnostic
panel LEDs” on page 29.
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 “Diagnostic panel LEDs” on page 29.)
Ethernet transmit/receive activity light:
When this green light is on, there is activity between the server from the
network.
Ethernet-link status light:
When this green light is on, there is an active connection on the Ethernet port.
