Note:
When operating in the expanded temperature range, ambient temperature warnings may be reported on the
LCD panel and in the System Event Log.
Expanded operating temperature restrictions
l
Do not perform cold start below 5°C due to hard drive constraints.
l
Apache Pass DIMM, NVDIMM, PCIe SSD, and NVMe are not supported.
l
LRDIMM >32 GB is not supported in x4 sockets configuration.
l
Rear installed drives and GPU configuration are not supported.
l
Redundant power supplies are required.
l
Non Dell EMC qualified peripheral cards and /or peripheral cards greater than 25 W are not supported.
l
Intel FPGA is not supported.
l
205 W SKUs, 200W/18C, 165W/12C, and 150W_8C processor are not supported on all x4 socket processor
configurations.
l
165 W SKUs, 130W/8C, 115W/6C, and 105W_4C are not supported on the x4 socket processor configurations
except front x8 inch SAS/SATA drives configurations.
Ambient temperature limitations
The ambient temperature limit must be adhered to ensure proper cooling and to avoid excess processor throttling,
which may impact system performance.
The following table lists configurations that require an ambient temperature of less than 35°C.
Note:
For all processor updates, see the Firmware documentation.
