Note
Operating speed and total memory capacity depends on the processor model and UEFI settings.
When four DCPMMs are installed, ensure that the processor TDP is lower than or equal to 125 watts.
A software RAID controller is integrated on the system board. The software RAID controller supports JBOD mode and RAID levels 0, 1, 5, and 10.
RAID 730-8i 1G Cache SAS/SATA adapter is not available for North America.
If RAID 730-8i 1GB/2GB Cache SAS/SATA adapter is installed, ThinkSystem 2.5" PM1653/PM1655 Read Intensive/Mixed Use SAS 24Gb SSD cannot be installed.
RAID 530-8i SAS/SATA adapter cannot be mixed with RAID 730-8i 1G Cache SAS/SATA adapter.
RAID 730-8i 2G Flash SAS/SATA adapter cannot be mixed with RAID 730-8i 1G Cache SAS/SATA adapter or RAID 930- 8i SAS/SATA adapter.
The RAID 940 adapters can be mixed with the ThinkSystem 440-8i SAS/SATA PCIe Gen4 12Gb HBA and the ThinkSystem 440-16i SAS/SATA PCIe Gen4 12Gb HBA.
Mixing of RAID/HBA 430/530/730/930 adapters (Gen 3) and RAID/HBA 440/540/940 adapters (Gen 4) in the same system is not allowed.
RAID 930/940 series or 9350 series adapters require a RAID flash power module.
RAID 5350/9350 series adapters cannot be mixed with HBA/RAID 430/440/530/540/730/930/940 series SAS/SATA adapters.
System fans
For server models with four 3.5-inch drive bays or server models with eight 2.5-inch drive bays:
One processor: four single-rotor hot-swap fans (including one redundant fan)
Two processors: six single-rotor hot-swap fans (including one redundant fan)
Note
If your server comes with only one processor, four system fans (fan 1 to fan 4) are adequate to provide proper cooling. However, you must keep the locations for fan 5 and fan 6 occupied by a fan filler to ensure proper airflow.
When the system is powered off but still plugged in to AC power, fans 1 and 2 may continue to spin at a much lower speed. This is the system design to provide proper cooling.
For server models with ten 2.5-inch drive bays: six dual-rotor hot-swap fans (including one redundant fan rotor)
Power supplies
One or two hot-swap power supplies for redundancy support
550-watt ac 80 PLUS Platinum
750-watt ac 80 PLUS Platinum
750-watt ac 80 PLUS Titanium
Note
For server models with four 3.5-inch simple-swap drive bays and 550-watt power supplies, if you want to install two processors, ensure that the processor Thermal Design Power (TDP) is less than or equal to 125 watts.
For server models with eight 2.5-inch hot-swap drive bays and 550-watt power supplies, if you want to install two processors, ensure that the processor TDP is less than or equal to 105 watts.
Electrical input
Sine-wave input (50–60 Hz) required
Input voltage low range:
Minimum: 100 V ac
Maximum: 127 V ac
Input voltage high range:
Minimum: 200 V ac
Maximum: 240 V ac
Note
For server models with 750-watt ac 80 PLUS Titanium power supplies, 100–127 V ac input voltage is not supported.
CAUTION
240 V dc input (input range: 180-300 V dc) is supported in Chinese Mainland ONLY. Power supply with 240 V dc input cannot support hot plugging power cord function. Before removing the power supply with dc input, please turn off server or disconnect dc power sources at the breaker panel or by turning off the power source. Then, remove the power cord.
In order for the ThinkSystem products to operate error free in both a DC or AC electrical environment, a TN-S earthing system which complies to 60364-1 IEC 2005 standard has to be present or installed.
Minimal configuration for debugging
One processor in processor socket 1
One DIMM in slot 3
One power supply
Three system fans (fan 1 to fan 3)
Acoustical noise emissions
Sound power level, idle
5.4 bels, minimum
5.5 bels, typical

Note
These sound power levels are measured in controlled acoustical environments according to procedures specified by ISO 7779 and are reported in accordance with ISO 9296.
The declared acoustic noise levels are based on specified configurations and they may change depending on configurations/conditions.
The declared acoustic noise levels may increase greatly, if high-power components are installed, for example, some high-power NICs, CPUs, and GPUs.

Particulate contamination
Attention
Airborne particulates and reactive gases acting alone or in combination with other environmental factors such as humidity or temperature might pose a risk to the server. For information about the limits for particulates and gases, see Particulate contamination.
Note
Your server complies with ASHRAE class A2 specifications. If your server comes with Intel Xeon 6240C processor, the operating temperature is equal to or less than 30 °C (86°F). The server performance might be impacted if one system fan fails. For server models with four 3.5-inch drive bays and server models with eight 2.5-inch drive bays, within the ASHRAE class A2 specifications, Intel Xeon 8164 processor is not supported if one system fan fails. For server models with four 3.5-inch drive bays and server models with eight 2.5-inch drive bays, within the operating temperature of 27 °C (81°F), Intel Xeon 6252N processor is not supported with full performance if one system fan fails.
Depending on the hardware configuration, some server models comply with ASHRAE class A3 and class A4 specifications if no system fan fails. To comply with ASHRAE class A3 and class A4 specifications, the server models must meet the following hardware configuration requirements at the same time:
Two power supplies are installed.
NVMe drive is not installed.
NVMe PCIe flash adapter is not installed.
DCPMM memory is not installed.
The following processors are not installed: Intel Xeon 6140, 6140M, or 6152.
Important information about EU ecodesign requirements
To meet the EU ecodesign requirements for energy-related products (ErP) Lot 9, your server must meet the following requirements:
Minimum memory: 16 GB
If your server is configured with one processor, these processors are not supported: Intel Xeon 3104, 3106, and 3204.
Particulate contamination Attention: Airborne particulates (including metal flakes or particles) and reactive gases acting alone or in combination with other environmental factors such as humidity or temperature might pose a risk to the device that is described in this document.
