White Paper

Cisco StackPower: Efficient Use of Power

Introduction

The Cisco StackPower

™

technology is an innovative feature that aggregates all of the available power in a stack of

switches and manages it as one common power pool for the entire stack. It is one of the main features introduced

in the Cisco

®

Catalyst

®

3750-X Series Switches (Figure 1).

Figure 1. Cisco StackPower

This white paper explains how Cisco StackPower manages power more efficiently, allowing customers to achieve

more granular control of their power use and to realize savings that reduce the total cost of ownership (TCO) of

their Cisco Catalyst switches.

This W hitepaper covers the following topics:

●

Benefits of Cisco StackPower

●

Technology Overview

●

Use Case for Cisco StackPower

●

Intelligent Power Management

●

Cisco StackPower Topology

●

Modes of Operation

●

Benefits of Cisco StackPower

The benefits of the Cisco StackPower technology are immediately tangible, and so are the savings.

Consider a stack of switches with each switch requiring a slightly higher power budget for some extra Power over

Ethernet (PoE) devices randomly scattered in the stack. Purchasing extra second power supply for each switch

that needs some additional power would be inefficient and expensive. W ith the Cisco StackPower solution, a

common pool of power is made available and additional power can be automatically redirected to the appropriate

switch based on the available power budget in the common power pool.
