Two power supply modules are required for redundancy. Each power supply can

be connected to a separate circuit to mitigate the risk of down‐time during a

localized power failure. When used in a redundant configuration, the dual power

supplies have a load‐sharing capability that enables each power supply to operate

at approximately 50 percent of full load.

Using redundant power can minimize the power disruption during a power supply

failure and extend the expected lifetime of each power supply by operating

normally in a conservative power mode.

For proper airflow when operating the switch with only one power supply module,

the empty power supply bay must be protected by a blank cover module.
