Symptoms

Koldstrømscyklus Dell 17G PowerEdge Intel-server med iDRAC10 1.20.70.50 (eller nyere) firmware genererer SYS565-hændelser, når den parres med ældre FPGA-firmware (Field-Programmable Gate Array). Både iDRAC10 Lifecycle Log (LCLOG) og System Event Log (SEL) registrerer en hændelse med hukommelsesmodulets temperatur, der er overskredet advarselsgrænsen.

 

Berørte servere:

  • PowerEdge R470
  • PowerEdge R570
  • PowerEdge R670
  • PowerEdge R770

 

Eksempel på livscykluslog:

2025-10-20 11:17:34   SYS566     The memory module temperature has returned to its normal value.

2025-10-20 11:16:54   SYS565     The memory module temperature has exceeded the warning threshold value.

2025-10-20 11:16:49   RAC1195    User requested state / configuration change to PowerControl using Redfish.

2025-10-20 11:16:48   SYS1005    The server power action is initiated because the management controller initiated a power-down operation.

2025-10-20 11:16:48   RAC0702    Requested system powercycle.

 

Eksempel på systemhændelseslog:

The memory module temperature has returned to its normal value.             Mon Oct 20 2025 11:17:34

The memory module temperature has exceeded the warning threshold value.     Mon Oct 20 2025 11:16:54

Cause

November 2025 iDRAC10 v1.20.70.50 og tilhørende platform FPGA-firmware introducerede en ny MEMHOT-funktion til 17G Intel PowerEdge-servere. Blanding af iDRAC10-firmware, der tilføjede understøttelse af denne funktion med FPGA-firmware, der ikke understøtter MEMHOT, fører til denne hændelsesobservation.

Resolution

FPGA-firmware introducerer understøttelse af MEMHOT-funktionen sammen med iDRAC10-firmware 1.20.70.50. Opdatering af 17G Intel PowerEdge-servere til denne firmware eller nyere afhjælper denne observation. Når der opstår en SYS5565 fejl for denne uoverensstemmende firmwareparring, retter fejlen selv og registrerer en SYS566-hændelse i LCLOG og SEL.

 

FPGA-versioner, der introducerede MEMHOT Support:

  • FPGA-version for R470/R570: 107.132.000
  • FPGA-version for R670/R770: 108.124.104
