The system error LED is turned on when an error is detected. Push the button beside the LED display on the System board to illuminate the LEDs. 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. The following chart is valid only when the system error LED is on.

Notes:

  • 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.
  • Check the System Error Log for additional information before replacing a FRU.
  • The DIMM error LEDs, processor error LEDs, and VRM error LEDs turn off when the system is powered down.
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. PFA alert; check Netfinity log (Netfinity Manager or Netfinity Director) for failure; clear PFA alert; remove AC power for at least 20 seconds, reconnect, then power up system.
  3. Run Information Panel diagnostics
CPU LED on (The LED next to the failing CPU should be on.)
  1. Processor 1 or 2
  2. System board
VRM LED on
  1. System board
DASD LED on (The LED located next to the drive bay that the failing drive isinstalled in will be turned on.)
  1. Failing drive
  2. Be sure the fans are operating correctly and the air flow is good
  3. SCSI Backplane
FAN LED on
  1. Check individual fan LEDs
  2. Replace respective fan
  3. System board
MEM LED on (The LED next to the failing DIMM   is on.)
  1. DIMM.
  2. Failing DIMM in slot J1-J4
  3. System board
PCI LED on
  1. Remove PCI adapters from slots 1-2
  2. System board
PS LED on
  1. Power supply
  2. System board
TEMP LED on (look at test cases)
  1. Ambient temperature must be within normal operating specifications
  2. Ensure fans are operating correctly
  3. Examine System Error Log
    System over recommended temperature
    Power switch assembly
    DASD over recommended temperature 
    a). Overheating hard drive
    b). DASD Backplane
    c). System board

    System over recommended temperature for CPU X (where X is CPU number,) (CPU LED also on)
    a). CPU X
    b). System board

    System board over recommended temperature
    a). System board
