PowerProtect One DM5510 CTL47 Single-bit ECC error

Alert Indicating DIMM Issue

The system reports the following alert:

• PPDMA DM5510 Alert CTL47 - Single-bit ECC error on the specified DIMM

DIMM Hardware Failure Triggering ECC Alerts

The DIMM has experienced a hardware malfunction that generates a single‑bit ECC error. The PPDMA DM5510 Alert CTL47 alert code identifies this condition and indicates that the memory module cannot reliably store or retrieve data.

• DIMM internal circuitry has degraded or failed, causing error detection mechanisms to mark a single‑bit ECC fault.
• The system firmware reports this error:

  PPDMA DM5510 Alert CTL47

  This pinpoints the affected DIMM.
• Because the DIMM is part of the controller battery pack, its failure directly impacts the controller’s ability to maintain data integrity.
• Data loss or corruption may occur if the faulty DIMM continues to operate.

Continued operation of a malfunctioning DIMM can lead to irreversible data loss or corruption.

Replace the DIMM immediately.

• The DIMM is a part of the controller battery pack.
• Refer to your hardware documentation for information about replacing the DIMM.
