• 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 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
