Power Supply Module Features - Cisco ME 3800X Installation Manual

Chapter 1 Product Overview

Power Supply Module Features

The Cisco ME 3800X and ME 3600X switches support two power supply modules, either AC or DC
input. You can install two AC or DC input power supply modules, a mix of AC and DC input power
supply modules, or one power supply and one fan module. The power supply and fan modules are
hot-swappable.
Both slots must be occupied either by two power supply modules or a power supply and a fan module.
Caution
Do not run the switch with an empty slot unless you are replacing a faulty power supply or fan module.
Running the switch with an empty slot triggers an alarm.
Each power supply module contains three fans. The switch can operate safely if one fan fails. A fan
failure triggers an alarm. When a fan fails, replace the power supply module immediately.
