1200-Watt AC-Input Power Supply
Replacement Instructions

Product Number: PWR-7513-AC(=), PWR-7513-ACU(=), PWR-7513-ACA(=),
PWR-7513-ACI(=), and PWR-7513-ACE(=)

This document contains instructions for installing or replacing a 1200-watt (W), alternating current
(AC)–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.
