Power Supply Fan

Each installed power supply module includes a fan that pulls air from within the system, through the power

supply, and out the back. Thermal monitoring will vary the fan speed. Should a power supply fan fail, the

resulting increase in temperature within the power supply will initiate its thermal protection circuit to shut

itself down. Power supply fans cannot be replaced. The power supply module must be replaced if its fan

stops working.

Note: A power supply module can be hot swapped in a dual power supply configuration where one of the

power supplies is shut down and the system is still operational.

9.3

For best system performance and to maintain the airflow necessary to keep the system operating below the

non-critical thermal limit, the following requirements must be met when the system is operational:

1. The system top cover must be installed. The only exception to this requirement is when hot swapping

a system fan. When performing this procedure, it must be completed as quickly as possible.

2. The system air duct must be installed.

3. All 48 memory slots must be populated with a memory device (DIMM or Intel® Optane™ PMem) or

DIMM blank. Pre-installed DIMM blanks should only be removed when replacing it with a memory

device.

4. All front drive bays must be populated with a drive carrier.

5. All drive carriers installed within the front drive bay must be assembled with a drive (HDD or SSD) or a

supplied drive blank.

6. All system fans and power supply fans must be operational.

7. Ambient air flowing into the system must be between 10–35 °C (50–95 °F).

8. For proper system ventilation, leave a minimum of 15 cm clearance in the front and rear of the

system.
