Limited operating inlet ambient temperature requirements
Limited operating inlet ambient temperature requirements
The maximum operating inlet ambient temperature value for most components installed in the server is 35°C (95°F). However,
installing some components in specific configurations are subject to temperature limitations. To ensure safe and reliable system
operation, identify the limited operating inlet ambient temperature required for these configurations.
In the following tables, the processor thermal design power (TDP) is set at a default value. Use the UEFI System Utilities to adjust the
TDP setting within preset limits—configurable TDP (cTDP).
From the System Utilities screen, select System Configuration > BIOS/Platform Configuration (RBSU) > Processor Options. Enter the
number in milliwatt (mW) for the Processor RAPL wattage value field.

AOC stands for active optical cable, while DAC stands for direct attach copper cable.
IMPORTANT:
IMPORTANT:
High-bandwidth HDR InfiniBand and Ethernet adapters might cause the fans to operate at high speeds to maintain
optimum system cooling. This high-speed fan operation can generate excessive fan noise and lead the system to be on
standby mode.
