ALM-0x08000017 Failed to Read PCIe Card Voltage (PCIe Card, Minor Alarm)

ALM-0x08000017 Failed to Read PCIe Card Voltage (PCIe Card, Minor Alarm)

Description

Alarm message (iBMC versions earlier than V308):

Failed to obtain voltage of the arg4 detection point on the arg1 arg3 PCIe card arg2. 

Alarm message (iBMC V308 or later):

Failed to obtain voltage of the arg4 detection point on the arg1 arg3 PCIe card arg2. [arg5] [arg6]

This alarm is generated when the system failed to obtain the voltage of the PCIe card.

Alarm object: PCIe card

Attribute

Alarm ID Alarm Severity Auto Clear

0x08000017

Minor

Yes

Parameters

Name Meaning
arg1

Location of the PCIe card. For example, front or rear.

arg2

Slot number of the PCIe card, for example, 1 or 2.

arg3

Type of the PCIe card, for example, M60 GPU.

arg4

Voltage detection point.

Example values:

  • 3V3, 0V95
  • VCC 5V0
  • NBS 1V8, NBS 0V9, AVS 0V9
  • DIMMA 0V6, DIMMB 0V6
  • FPGA 1V8, FPGA 1V2, FPGA 1V
  • DDR 1V2, DDR 2V5
arg5

Supplementary information about the alarm, for example, Error Code.

NOTE:

This parameter is available only for iBMC V308 and later versions.

arg6

Error code of the alarm, for example, (7176).

NOTE:

This parameter is available only for iBMC V308 and later versions.

Impact on the System

The voltage cannot be monitored. No alarm will be reported when the voltage is not in the normal range. The hardware self-protection function fails.

Possible Causes

The I2C channel is abnormal or the PCIe card is faulty.

Procedure

  1. Restart the iBMC. Then, check whether the alarm is cleared.

    • If yes, no further action is required.

    • If no, go to 2.

  2. Remove and reinstall the power cable or board. Then, check whether the alarm is cleared.

    • If yes, no further action is required.

    • If no, go to 2.

  3. Replace the PCIe card. Then, check whether the alarm is cleared.

    • If yes, no further action is required.

    • If no, go to 4.

  4. Contact Huawei technical support.
