Operator inform ation p anel The following illustration shows the lights on the operator information panel on the
front of the server. (See “Server controls and indicators” on page 5 for the location of
the operator information panel.)

SCSI hard disk drive activity light: This green light is on when there is activity on a
hard disk drive.
Ethernet transmit/receive activity light: When this green light is on, there is
transmit or receive activity to or from the server. This light stays on even if the server
power is turned off.
Ethernet link status light: This green LED lights when there is an active connection
on the Ethernet port during typical operation, when the system is powered off the
LED remains green.
Information light: This amber light is on when the information log contains
information about certain conditions in your server that might affect performance.
System error light: This amber light is lit when a system error occurs. An LED on the
diagnostic LED panel will also be on to further isolate the error.
See “Diagnostics panel” on page 104 for more information on the diagnostics panel.

enabled in the Configuration/Setup utility program, the server will start
automatically when power is restored.

Configuration/Setup utility program, the wake-up feature will turn on the server at
