Cisco Systems WSC4500XF32SFP, WSC4500X24XIPB manual Site Power Requirements and Heat Dissipation

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 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: http://www.cisco.com/univercd/cc/td/doc/product/lan/cat4000/hw_doc/mod_inst /0aspecs.htm#wp1012188.
