Cisco 7513 DC-Input Power Supply Specifications
Dual power supplies are automatically load-sharing and redundant, which means that you can install
or replace a second power supply on line. During normal operation, dual supplies provide system
power simultaneously (load share). When you remove one supply, the remaining supply
immediately ramps up to provide full power and maintain uninterrupted power to the system.
Whenever possible, connect each power supply to a separate DC source.
1. VDC = volts direct current.
