Before beginning installation
This section describes how to change a power supply/fan assembly for a unit with a port-side air
exhaust. A new power supply/fan assembly field replaceable unit (FRU) must have the same part
number (P/N) as the FRU being replaced. The manufacturing P/N is located on the top of the power
supply/fan assembly.
The fans inside a power supply/fan assembly FRU either intake air or exhaust air from the chassis,
depending on the model. If your FRU requires port-side air intake, refer to the Combined Power Supply
and Fan Assembly Replacement Procedure for Port-side Air Intake. In addition to the part number, port-
side intake assemblies are also identified by a green label with an E on it.
Using the same P/N for all power supply/fan assembly FRUs ensures identical airflow for all the FRUs
on the chassis. The power supply/fan assembly unit handle color is also an indicator of the model type.
The handles for the installed FRUs must be the same color.

The following figure shows the two combined power supply and fan assemblies. Fabric OS identifies the
FRUs from left to right as fan assembly #2 and fan assembly #1.

Disassembling any part of the power supply and fan assembly voids the warranty and regulatory
certifications. There are no user-serviceable parts inside the power supply and fan assembly.
