Upgrading the 1200-Watt, AC-Input
Power Supplies in the Cisco 7513
This document contains instructions for upgrading your existing Cisco 7513, 1200-watt (W), alternating current (AC)–input power supplies, with new AC-input power supplies. (See .) 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.
Caution The new and older power supplies must not be used simultaneously in the Cisco 7513. The redundant power, load-sharing feature of the Cisco 7513 requires identical power supplies in each of the two power supply bays. While no physical damage will occur if two different supplies are installed into a Cisco 7513, there is the possibility of erratic system behavior and error messages.
Note If your Cisco 7513 contains older AC-input power supplies, Part Number 34-0049-01, or later, use this document to replace them with new power supplies carrying Part Number 34-0667-01 or later. If you have a Cisco 7513 with one or two of the older AC-input power supplies, you must replace both of them with the new AC-input power supplies. All Cisco 7513 chassis must have the new AC-input power supplies installed in them.
