3845 AC-IP Power Supply
The Cisco 3845 AC, AC-IP, and DC power supplies are field-upgradeable and orderable as spares. In addition, each power supply is hot-swappable and provides status signals for proper operation and installation. The Cisco 3825 AC power supply may also be replaced in the field, but the chassis must be removed from a rack, the top opened, the wiring harness unplugged, and the power supply mounting screws undone.
