Catalyst 6500 Series Switches Installation Guide

OL-5781-04

Chapter 2 Preparing for Installation

Power Requirements

• You can connect the DC-input power supply to the power source with heavy gauge wiring connected

to a terminal block. The wire gauge size is determined by local electrical codes and restrictions.

• If you are using a 200/240 VAC power source in North America, the circuit must be protected by a

two-pole circuit breaker.

• The source AC outlet must be within 6 feet (1.8 meters) of the system and should be easily

accessible.

• The AC power receptacles used to plug in the chassis must be the grounding type. The grounding

conductors that connect to the receptacles should connect to protective earth ground at the service

equipment.

Power Connection Guidelines for AC-Powered Systems

This section provides the basic guidelines for connecting the Catalyst 6500 series switch AC power

supplies to the site power source:

• Each chassis power supply should have a separate, dedicated branch circuit.

• For North America:

–

The 950 W power supply requires a 15 A circuit.

–

The 1000 W power supply requires a 15 A or 20 A circuit.

–

The 1300 W, 1400 W, 2500 W, 2700 W, and 3000 W power supplies require a 20 A circuit.

–

The 4000 W power supply requires a 30 A circuit.

–

The 6000 W power supply requires one or two 20 A circuits.

Note With one 220 VAC, 20 A circuit, the 6000 W power supply is limited to 2900 W.

• For International:

–

Circuits should be sized according to local and national codes.
