messages issued during POST and all system status messages from the Netfinity Advanced System Management Processor. To view the contents of the error logs, start the Configuration/Setup Utility program; then, select Event/Error Logs from the main menu. Small computer system interface messages The table in "SCSI error codes" on page 141 lists actions to take if you receive a SCSI error message. Note: If your server does not have a hard disk drive, ignore any message that indicates that the BIOS is not installed. You will get these messages only when running the SCSISelect Utility. Identifying problems using status LEDs If the System Error light in the operator information panel on the front of the server is on, one or more LEDs inside the server or on the power supplies will be on. Use the light path diagnostics to identify the type of error that occurred. Light path diagnostics You can use the light path diagnostics built into your server to quickly identify the type of system error that occurred. Your server is designed so that any LEDs that are illuminated remain illuminated when the server shuts down as long as the AC power source is good and the power supplies can supply +5V dc current to the server. This feature helps you isolate the problem if an error causes the server to shut down. See "Light path diagnostics table" on page 15. Power supply LEDs The AC and DC Power LEDs on the power supply provide status information about the power supply. See "Power supply LED errors" on page 134. Diagnostics panel The following illustration shows the LEDs on the diagnostics panel on the system board.

You
can
use
the
light
path
diagnostics
built
into
your
server
to
quickly
identify
the
type
of

is
designed
so
that
any
LEDs
that
are
illuminated
remain
illuminated
when
the

shuts
down
as
long
as
the

power
source
is
good
and
the
