Fan Modules; Power Supplies - H3C UniServer R6900 G6 Technology White Paper


To install HHHL single-width GPU, install them to slots as shown in
and follow these guidelines:
If the number of GPU modules is equal to or greater than 8, you can install GPU modules to

PCIe slots with x8 bus bandwidth.
In other cases, install GPU modules to PCIe slots with x16 bus bandwidth.

Fan modules

Fan modules are hot swappable.
Make sure all four fan modules are installed correctly on the server.

Power supplies


To avoid damage to hardware, use only H3C approved power supplies.

The server supports N+N power supply redundancy.

The power supplies installed on the server must be the same model. If they differ in model,
HDM would raise a minor alarm.

The power supplies are hot swappable.

The system provides an overtemperature mechanism for power supplies. The power supplies
automatically turn off when they encounter an overtemperature situation and automatically turn
on when the overtemperature situation is removed.
For more information about the specifications of power supplies, see the power supply manuals for
them.
