The Brocade X7-8 Director can have up to four power supplies in a 2+2 full redundant configuration. Only two PSUs are
required at any given time to support all possible blade configurations using AC high-line (200 to 240 VAC). See "Power
Supply Requirements" in the
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. If four
power supplies are installed, four primary power connections are required for the X7-8 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.
