Cisco 3110 Hardware Installation Guide

AC Power Supply
The dual power supplies can supply up to 800-W power across the input voltage range. The load is shared
when both power supply modules are plugged in and running at the same time.
The system does not consume more than the capacity of one power supply module, so it always operate in
full redundancy mode when two power supply modules are installed.
