1200-Watt DC-Input Power Supply
Replacement Instructions
Product Number: PWR-7513-DC(=)
This document contains instructions for installing or replacing a 1200-watt (W), direct current
(DC)–input power supply in the Cisco 7513.
A single power supply is standard equipment for the Cisco 7513. A second, identical power supply,
when installed, provides redundant power.
In systems with redundant power, the power supplies are load-sharing and fully hot-swappable; you
can remove and replace one supply, while the remaining supply immediately ramps up to full power
to maintain uninterrupted system operation.
