Undetermined Problems (Netfinity 7000-M10 - Type 8680)

Undetermined Problems

You are here because the diagnostic tests did not identify the failure, the Devices List is incorrect, or the system is inoperative.


  1.  If you suspect a software mismatch is causing failures (solid or intermittent), be sure to see 'Resolving Configuration Conflicts'.
  2.  A corrupt CMOS can cause undetermined problems.

Check the LEDs on all the power supplies, see 'Power Supply LED Errors'.
If the LEDs indicate the power supplies are working correctly, do the following:

  1.  If a component has been added, reseat the added component and components around it, and retest.
  2.  If the system has been moved recently, reseat all the components and retest.
  3.  Check the LEDs on the processor board, see 'Processor Board Component Locations'.

    1.  Check the 2.5V LED, if not on, replace processor board.
    2.  Check the VRM error LEDs. There are two VRMs per processor.
       For the VRM LED to be off, a good processor and two good VRMs (A and B) must be installed.
       If a LED is on:

       1) Replace VRM A and VRM B.
       2) Replace the processor.

    3.  Check Termination LED. If not on:

       1) Ensure a processor card is in slot 1 and a processor or terminator is in slot 4.
       2) Reseat Processor/terminator in slot 4.
       3) Replace Processor/terminator in slot 4.

    4.  Check Power Good LED (Verify jumper J5 is on pins 1 & 2, default positions).
       If not on:

       1) Replace Processor Board.
       2) Replace I/O Board.

    5.  Check ERR0 and ERR1 LEDs.

       1) If ERR0 on and ERR1 off, F16 bus error:
       a) Replace I/O Board.
       b) Replace Processor Board.

       2) If ERR0 off and ERR1 on, memory bus error, strip to single bank, and retest.
       If still on:

       a) Replace single bank of DIMMs.
       b) Replace Memory Board.
       c) Replace Processor Board.

       3) If ERR0 on and ERR1 on, processor bus error, strip to single processor in slot 1 and
       processor/terminator to slot 4.
       If still on:

       a) Replace terminator.
       b) Replace processor.
       c) Replace processor board.

  4.  Check the I/O board LEDs, see 'I/O Board Component Locations'.

    1.  Check I/O Board Power Supply Power Good LED.
       If not on, replace power control card.
    2.  Check Reset LEDs. If on:

       1) Replace I/O Function Card.
       2) Replace I/O Backplane

    3.  Check PCI slot power LEDs. If adapter is present but power LED is not on:

       1) Ensure hot plug switch is closed.
       2) Replace adapter.
       3) Replace PCI sensor card.
       4) Replace I/I board.

    4.  Check PCI bus SERR/PERR LEDs. If on, (error on PC A, B, or C bus), replace or remove  adapters in the appropriate PCI slots.
    5.  Check Secondary PCI SERR/PERR LEDs. If on, (error on secondary bus):

       1) Replace I/O Function card.
       2) Replace system management card.

    6.  Check NMI LED. If on:

       1) Replace I/O Board.
       2) Replace processor.
       3) Replace processor board.

  5.  Check Memory Card error LEDs. If any error LED is on:

    1.  Replace the DIMM for that LED.
    2.  Replace the memory card for that LED.

  6.  Power-off the computer.
  7.  Be sure the system is cabled correctly.
  8.  Remove or disconnect the following (one at a time) until you find the failure  (power-on the computer and reconfigure each time).

    Note: Minimum operating requirements are:

  9.  Put a jumper on I/O board jumper J7, then, power-on the computer.  If the problem remains, suspect the following FRUs in the order listed:

Note: If the problem goes away when you remove an adapter from the system, and replacing that adapter does not correct the problem, suspect the I/O board then the processor board(s)
