Diagnostic panel error LEDs for Netfinity 6000R.

Resolving The Problem

This document is intended for trained servicers who are familiar with IBM Personal Computer products. Use this document along with advanced diagnostic tests to troubleshoot problems effectively. Before servicing an IBM product, be sure to review the safety information. Click here to review safety information.

The system error LED is turned on when an error is detected. If the system error LED is on, remove the cover and check the diagnostic panel LEDs. The following is a complete list of diagnostic panel LEDs followed by the FRU/Action for correcting the problem.

NOTES:

  1. If a diagnostic panel LED is on and the information LED panel system error LED is off, there is probably an LED problem. Run LED diagnostics.
  2. To locate the LEDs on the system board see "System board component locations" in the HMM.
  3. Check the System Error Log for additional information before replacing a FRU.
  4. It may be necessary to view the System Error Log from a remote connection, such as MOST.
  5. The memory card DIMM error LEDs and processor error LEDs turn off when the system is powered down.
  6. The System Error LED will also be on.

Diagnostic Panel LED FRU/Action
All LEDs off
(Check System Error Log for error condition, then clear System Error Log when the problem is found.)
  1. System Error Log is 75% full; clear the log.
  2. Bad, missing or mis-installed processor terminator; remove and reinsert terminator.
  3. PFA alert; check Netfinity log for failure; clear PFA alert; remove AC power for at least 20 seconds, reconnect, then power up system.
  4. Run Information Panel diagnostics.
CPU LED on (The LED next to the failing CPU should be on.)
  1. Insure terminator (or processor if multiprocessor system) is installed in slot D. See "Installing a microprocessor kit" in the HMM.
  2. Processor 1, 2, 3, or 4
  3. System Board.
DASD LED on (Check amber drive LED for a failing hard drive if RAID system.)
  1. Be sure the fans are operating correctly and the air flow is good.
  2. Failing drive.
  3. SCSI Backplane.
FAN LED on
  1. Check individual fan LEDs.
  2. Replace respective fan.
  3. Fan Cable.
  4. System Board.
  5. Power Backplane Board.
MEM LED on (The LED next to the failing DIMM is on.)
  1. Failing DIMM(s) in slot J1-J16.
  2. Memory Card.
  3. System Board.
NMI LED on
NOTE: NMI LED can only be turned off by removing ac power from system, then restoring AC power.
  1. Reboot the system.
  2. Check the System Error Log.
PCI A LED on
  1. Check System Error Log for additional information.
  2. PCI card in slot 1. See "System board component locations" in the HMM.
  3. Remove all PCI adapters from slots 1-6.
  4. Replace failing PCI adapter.
  5. System Board.
PCI B LED on
  1. Check System Error Log for additional information.
  2. PCI card in slots 2-4. See "System board component locations" in the HMM.
  3. Remove all PCI adapters from slots 1-6.
  4. Replace failing PCI adapter.
  5. System Board.
PCI C LED on
  1. Check System Error Log for additional information.
  2. PCI card in slots 5-6. See "System board component locations" in the HMM.
  3. Remove all PCI adapters from slots 1-6.
  4. Replace failing PCI adapter.
  5. System Board.
PS1 LED on
  1. Check the DC Good LED on power supply 1. If off, replace power supply 1.
  2. Power Backplane.
PS2 LED on
  1. Check the DC Good LED on power supply 2. If off, replace power supply 2.
  2. Power Backplane
PS3 LED on
  1. Check the DC Good LED on power supply 3. If off, replace power supply 3.
  2. Power Backplane.
SP Bus on
  1. SP Bus card.
  2. System Board.
Event Log Not implemented at this time.
Non Red
  1. Check PS1, PS2, and PS3 LEDs and take the actions for those indicators.
  2. See "Diagnostic panel error LEDs" in the HMM.
TEMP LED on
  1. Ambient temperature must be within normal operating specifications. See "Features and specifications" in the HMM.
  2. Ensure fans are operating correctly.
  3. Examine System Error Log.
    1. DASD over recommended temperature (DASD LED also on)
      1. Overheating hard drive
      2. DASD Backplane
      3. System Board

    2. System over recommended temperature for CPU X
      (where X is CPU 1, 2, 3, or 4) (CPU LED also on)
      (1) CPU X
