Consider the following information when connecting AC power:
•
The X7-4 Director has two power supplies installed. The use of the high-voltage line (200 to 277 VAC) is advised
because of better power conversion efficiency. See "Power Supply Requirements" in the
Brocade X7 Director
Technical Specifications
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 X7-4 Director for optimum efficiency and redundancy.
Power supplies can be removed and replaced without special tools. If you are replacing one power supply in a
configuration with N+1 or greater redundancy, the director can continue operating during the replacement if procedures
in this guide are followed. Otherwise, installed blades may power off. See "Power supply requirements" in
Brocade X7
Director Technical Specifications
for more information about power supply redundancy.
Power cords are available from Brocade. Power cords are 6m (19.68 ft.) long and contain three colored 14 AWG
unterminated wires, which are described in the following table:

Power cords have an Anderson Saf-D-Grid 400 connectors on the power supply end and unterminated wires on the other
end for attaching to AC or DC power sources. Either attach an AC power plug to these wires that meet your facility and
local code requirements or connect wires to appropriate DC power terminal blocks.
Power Supply Assembly Numbering
The following figure illustrates the location and number identification of power supply assemblies in the chassis.

Fan and Power Supply Airflow
All fans and power supply FRUs installed in this device must have either NPI (nonport-side intake) or NPE (nonport-
side exhaust) airflow. You must order a replacement FRU with the same part number (P/N) as the FRU being replaced
to provide the same airflow. The manufacturing P/N, located on the top of the FRU, contains either NPI or NPE. If a
