Power Supply Assemblies
This section describes the power supply assemblies that are supported by your device.
The section also includes instructions for removing and installing a power supply assembly.
AC Power Supply Overview
This device supports the following AC power supply assemblies. All power supplies installed in the device must be of the
same type and must match the airflow of installed fan assemblies.
•
The power supply model supporting nonport-side air intake (NPI) provides 1450W (100–120 VAC) and 2870W (200–
240 VAC). This assembly has two fans that move the air from the nonport side to the port side of the device.

The power supply model supporting nonport-side air exhaust (NPE) provides 1450W (100–120 VAC) and 2870W
(200–240 VAC). This assembly has two fans that move the air from the port side to the nonport side of the device.
The following figure illustrates the power supply assembly components.

The Brocade X6-4 Director has two power supplies installed. The use of the high-voltage line (200 to 240 VAC) is highly
recommended because of better power conversion efficiency. See "Power Supply Requirements" in the
for minimum power supplies required for AC low and high voltage line operation, redundancy in case of
power supply failure, and other specifications.
Redundant AC primary power connections ensure high availability. Each power supply has its own connector, so two
primary power connections are required for the Brocade X6-4 Director for optimum efficiency and redundancy.
Power supplies can be removed and replaced without special tools. If replacing one power supply, the device can
continue operating during replacement if procedures are followed in this guide.
