Catalyst 4500 Series Installation Guide

78-14409-03 B0

Catalyst 4500 series switches support one power supply and an optional

redundant power supply. Each power supply has an individual power cord and

status LEDs. Systems with redundant power supplies will share the load, with

each unit providing approximately one-half of the total load. For information

about configuring your switch for redundant and combined modes, refer to the

software configuration guide for your switch.

When power is removed from one power supply on a Catalyst 4500 series switch

that has two power supplies, the redundant power feature causes the second power

supply to produce full power.

To replace a power supply, see the “Removing and Replacing the Power Supply”

section on page 4-2.
