BladeCenter GPU expansion unit light path diagnostics LEDs

Use this information to diagnose and resolve possible errors displayed by the light path diagnostic LEDs in the BladeCenter GPU expansion unit.

The following table describes the LEDs on the expansion unit system board and suggested actions to correct the detected problems. Follow the suggested actions in the order in which they are listed in the Action column until the problem is solved.

  • Follow the suggested actions in the order in which they are listed in the Action column until the problem is solved.
  • See Parts listing to determine which components are CRUs and which components are FRUs.
  • If an action step is preceded by "(Trained service technician only)," that step must be performed only by a trained service technician.
Lit light path diagnostics LEDDescriptionAction
LPThe light path LEDs have power.

If the LP LED is green, check for error LEDs that are lit in the expansion unit.

If the LP LED is off, install the expansion unit on the blade server and install the combined assembly into the BladeCenter for 5 to 10 minutes to recharge the LEDs.

NoneAn error has occurred and cannot be isolated.
  1. Make sure that the LP LED is lit to ensure that there is enough power in the expansion unit to light the rest of the LEDs.
  2. Check the event logs on the blade server and Advanced Management Module for information about an error that is not represented by a light path diagnostics LED.
GPUA GPU adapter error has occurred.
  1. Make sure that the GPU adapter installed in the PCIe connector is supported.
  2. Check the auxiliary power cable.
  3. Replace the GPU adapter installed in the PCIe connector.
  4. (Trained service technician only) Replace the expansion unit.
CFFhA CFFh adapter error has occurred.
  1. Make sure that the adapter installed in the CFFh connector is supported.
  2. Reseat the adapter installed in the CFFh connector.
  3. Replace the adapter installed in the CFFh connector.
  4. (Trained service technician only) Replace the expansion unit.
BPE4An error has occurred in the expansion unit.
  1. Check for other specific error LEDs that are lit in the expansion unit.
  2. (Trained service technician only) If no other error LEDs are lit, replace the expansion unit.
Ck NxtAn error has occurred in an expansion unit installed below this expansion unit in the stack.(Trained service technician only) Remove this expansion unit and check for error LEDs that are lit in the expansion unit beneath it.
