Information LED panel: The lights on this panel give status information for
the server. See "Information LED panel".
The following illustration shows the status lights on the Information LED panel.
1
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.
2
POST-complete light: This green light is on when the power-on self-test
(POST) completes without any errors.
3
Hard disk drive activity light: This green light flickers when there is activity
on a hard disk drive.
4
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 44. A light on the diagnostic
panel may also be on; see "Diagnostic panel LEDs" on page 28.
5
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 28.)
