Information message panel: System monitor information appears on this
display. The Advanced System Management PCI adapter monitors system
functions and generates the messages.
When the server is in standby mode (the system power supply is turned off
and ac current is present), the information message panel can display system
monitor information.
System error light: This amber light is on when a system error occurs.
Information about the condition displays on the information message panel.
SCSI hard disk drive in-use light: This green light is on when there is
activity on a hard disk drive.
Attention: If the System Power Light is off, it does not mean there is no
electrical current present in the server. To remove all electrical current from
the server, you must unplug the server power cords.
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 (ac
current is present). When this light is off, it indicates either power supply
failure or an ac power failure, or the power cords have been disconnected.
