Light Path Diagnostics - Netfinity 5600 - Type 8664


Light Path Diagnostics:

Diagnostics Panel LED


You can use the light path diagnostics built into the server to quickly identify the type of system error that occurred.
The 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.

System Error
LED
(information
LED panel)
Lit
diagnostics
panel LED
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.
See 'POST Error Log' for information
about clearing the error log.
Disconnecting the server from all power
sources for at least 20 seconds will
turn off the System Error LED.
  CPU One of the microprocessors has
failed or a microprocessor is
installed in the wrong
connector.
1. Check the Microprocessor Error LEDs
on the processor board.
2. Turn off the server, reseat the
microprocessor indicated by the lit
Microprocessor Error LED, and
restart the server.
3. If the problem persists, replace
the microprocessor.
  VRM One of the voltage regulator modules
on the processor board has failed.
1. Check the VRM Error LEDs on the
processor board.
2. Turn off the server, reseat the
VRM indicated by the lit VRM
Error LED, and restart the
server.
3. If the problem persists, replace
the VRM.
  MEMORY A memory error occured. 1. Check the DIMM Error LEDs on
the memory board.
2. Replace the DIMM indicated
by the lit DIMM Error LED.
  PCI BUS A An error occured on PCI bus A.
An adapter in PCI slot 1 or 2 on
the system board caused the error.
1. Check the error log for additional
information. If the error log
indicates a problem with the
integrated Ethernet controller,
replace the system board.
2. If you cannot isolate the failing
adapter 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 slot 1 and 2) and restarting
the server after each adapter is
removed.
  PCI BUS B An error occured on PCI bus B.
An adapter in PCI slot 3, 4, or
5 or the system 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 B
(PCI slot 3-5 ) and restarting
the server after each adapter is
removed.
  HDD A hot-swap hard disk drive
has failed on bus 1.
1. Check the error log for additional
information. If the error log
indicates a problem and the fans are
working correctly, go to
'General Checkout'.
2. If the amber Hard Disk Status LED on
one of the hot-swap hard disk drives
is on, refer to the
'ServeRAID Information' section of
this Server Library for more information.
  NMI A nonmaskable interrupt occurred. 1. If the PCI BUS A or PCI BUS B LED is
on, follow the instructions for those LEDs.
2. If the PCI BUS A or PCI BUS B LED is
not on, restart the server.
  SMI A system management event occured. Restart the server
  SERVICE
PROCESSOR
BUS
An error has occurred on the
service processor bus.
Disconnect all power from the server for
30 seconds. Reconnect the power to the
server, then, restart the server.
  POWER
SUPPLY 1
Power supply 1 has failed Replace power supply 1.
  POWER
SUPPLY 2
Power supply 2 has failed Replace power supply 2.
  POWER
SUPPLY 3
Power supply 3 has failed Replace power supply 3.
  POWER SUPPLY
NON
REDUNDANT
Power supply redundancy has
been lost.
1. If one of the power supply LEDs is on,
replace the indicated power supply.
2. Install an additional power supply to
regain redundancy.
  FAN 1 Fan 1 has failed or is operating
too slowly.
Notes:
1. An LED on the failing fan assembly
will also be on.
2. A failing fan can also cause the
TEMPERATURE and HDD LEDs to be on.
Replace fan 1.
  FAN 2 Fan 2 has failed or is operating
too slowly.
Notes:
1. An LED on the failing fan assembly
will also be on.
2. A failing fan can also cause the
TEMPERATURE and HDD LEDs to be on.
Replace fan 2.
  FAN 3 Fan 3 has failed or is operating
too slowly.
Notes:
1. An LED on the failing fan assembly
will also be on.
2. A failing fan can also cause the
TEMPERATURE and HDD LEDs to be on.
Replace fan 3.
  TEMPERATURE The system temperature has exceeded
a threshold level.
1. Check to see if a fan has failed.
If it has, replace the fan.
2. Make sure the room temperature is
not too hot.
(See 'Specifications'.)
Off None The light path diagnostics have not
detected a system error.
None
