Ethernet Power

Consumption for

Cisco®Switches

Introduction

Why is network power

consumption important?

How can we measure it?

How much power do

Ethernet switches consume?

Network Power Consumption

Customers calculating total cost of ownership

need to factor in power consumption.

Likewise, power consumption contributes to

a company’s carbon footprint.

Miercom was commissioned by Cisco to measure

power consumption in Ethernet switches

Power Consumption Examples

33 watts is the power consumed by a ceiling fan at

average speed.

60 watts is the power required to light an incandescent bulb.

80 watts is the power consumed by an average PC.

200 watts is the power consumed by an average LCD.

Supports Gigabit Ethernet

The Cisco®WS-C2960G supports

Gigabit Ethernet. The other

switches support only Fast

Ethernet, which results in

increased power consumption.
