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.
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.
CAUTION
Changes or modifications made to this device that are not expressly approved by the party
