Chapter 2 Preparing for Installation

Site Power Requirements and Heat Dissipation

When removing a component, use any available ejector levers or captive installation screws to release the bus connectors from the backplane or midplane.

Handle carriers by available handles or edges only; avoid touching the printed circuit boards or connectors.

Place a removed component board-side-up on an antistatic surface or in a static shielding container. If you plan to return the component to the factory, immediately place it in a static shielding container.

Avoid contact between the printed circuit boards and clothing. The wrist strap only protects components from ESD voltages on the body; ESD voltages on clothing can still cause damage.

Never attempt to remove the printed circuit board from the metal carrier.

Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohm (Mohm).

Site Power Requirements and Heat Dissipation

This section provides module power requirements and heat dissipation specifications for the

Catalyst 4500 E-series switches. You should verify site power before you install the switch.

For more information about power management and planning, refer to the “Environmental Monitoring and Power Management” chapter in the Catalyst 4500 Series Switch Cisco IOS Software Configuration Guide version appropriate for your software.

Knowing the power requirements is useful for planning the power distribution system needed to support the switches. You should consider the heat dissipation specifications when estimating the air-conditioning requirements for an installation. For all Catalyst 4500 series switches, supervisor engines, and switching modules in AC or DC environments see the Catalyst 4500 Series Module Installation Guide at:

Catalyst 4500 E-series supervisor engines and switching modules are discussed elsewhere in this book.

Power Connection Guidelines for AC-Powered Systems

This section provides guidelines for connecting the Catalyst 4500 E-series switch AC power supplies to the site power source. Basic guidelines include the following:

Make sure each chassis power supply has its own dedicated branch circuit.

Size the circuits according to local and national codes.

If you are using a 200/240 VAC power source in North America, use a two-pole circuit breaker to protect the circuit.

Place the source AC outlet within 6 feet (1.8 meters) of the system and make sure it is easily accessible.
