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 LEDs remain
illuminated when the server shuts down, as long as the power supplies are operating
properly. This feature helps you to isolate the problem if an error causes the server to
shut down.

Cause Action
On
A system error
was detected.
Check to see
which of the
LEDs on the
diagnostics panel
inside the server
are on.
None The system error log is 75% or more
full or a PFA alert was logged. Check the system error log and correct
any problems. Disconnecting the
server from all power sources for at
least 20 seconds will turn off the
system error LED.
On SMI A systems management event
occurred. Restart the server.
If the problem persists, have the
system serviced.
On NMI A nonmaskable interrupt occurred.
The PCIA or PCIB LED will probably
also be on. 1. If the PCIA or PCIB LED is on,
follow the instructions for those
LEDs.
2. If the PCIA or PCIB LED is not
on, restart the server.
If the problem persists, have the
system serviced.
On SP The service processor has failed. Have the system serviced.
On PCIA An error occurred on PCI bus A. An
adapter in PCI slot 1 or 2, or the
processor board caused the error. 1. Check the error log for additional
information.
2. If you cannot correct the problem
from the information in the error
log, try to determine the failing
adapter by removing one adapter
at a time from PCI bus A (PCI
slots 1 and 2) and restarting the
server after each adapter is
removed.
If the problem persists, have the
system serviced.
