ALM-0x28000003 Incorrect Connection of CPLD Signal Cables (Cable, Major Alarm)
Description
Alarm message:
Incorrect connection (signal cable arg1) between the mainboard and the arg2.
This alarm is generated when the connection between the mainboard and the drive backplane or PCIe riser cardis incorrect.
Alarm object: cable
Parameters
| Name | Meaning |
|---|---|
arg1 |
Serial number of the signal cable. |
arg2 |
Component to which the signal cable connects. For example, drive backplane or PCIe riser card. |
Impact on the System
The iBMC cannot obtain information from the drive backplane or PCIe riser card. As a result, information about the hard disks and PCIe cards in the server, drive backplane CPLD version, and PCIe riser card version cannot be displayed normally.
Possible Causes
- The connection between the mainboard and the drive backplane is abnormal.
- The connection between the mainboard and the PCIe riser card is abnormal.
Procedure
- Check whether the drive backplane or PCIe riser card cables are connected correctly.
For details about the cable connection sequence, see the user guide of the server you use.
- Connect the drive backplane or PCIe riser card cables in correct sequence. Then, check whether the alarm is cleared.
If yes, no further action is required.
If no, go to 4.
- Remove and reconnect the drive backplane or PCIe riser card cables. Then, check whether the alarm is cleared.
If yes, no further action is required.
If no, go to 4.
- Replace the drive backplane or PCIe riser card cables. Then, check whether the alarm is cleared.
If yes, no further action is required.
If no, go to 5.
- Replace the mainboard. Then, check whether the alarm is cleared.
If yes, no further action is required.
If no, go to 6.
- Contact technical support engineer.
