This document contains instructions for installing or replacing a 1200-watt (W), AC-input power
supply in the Cisco 7513 and Cisco 7576 routers.
Note If you are upgrading a Cisco 7513 to a Cisco 7576, use this document as a reference for
transferring power supplies from the Cisco 7513 to the Cisco 7576.
A single power supply is standard equipment in the Cisco 7513. A dual power supply is standard
equipment in the Cisco 7576. A second 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 power supply while the remaining supply immediately powers up to
provide full power and to maintain uninterrupted system operation.
