Cisco Systems 2975 manual Rack-Mounting, Equipment That You Supply, Before You Begin

6Rack-Mounting

This section covers basic 19-inch rack-mounting and switch port connections. For alternate mounting procedures, such as installing the switch in a 24-inch rack or on a wall, and for additional cabling information, see the hardware installation guide on Cisco.com.

Equipment That You Supply

You need a number-2 Phillips screwdriver to rack-mount the switch.

Before You Begin

Before installing the switch, verify that these guidelines are met:

•Clearance to front and rear panels is such that

–Front-panel indicators can be easily read.

–Access to ports is sufficient for unrestricted cabling.

•Confirm that you have access to the switch rear panel to connect the optional RPS 2300 or the RPS 675. If you do not have access to the rear panel, you should cable the switches before you rack-mount them.

•Verify that the AC power cord can reach from the AC power outlet to the connector on the switch rear panel.

•Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent lighting fixtures. Make sure the cabling is safely away from other devices that might damage the cables.

•Airflow around the switch and through the vents is unrestricted.

•Temperature around the unit does not exceed 113°F (45°C). If the switch is installed in a closed or multirack assembly, the temperature around it might be greater than normal room temperature.

•Humidity around the switch does not exceed 85 percent.

•Altitude at the installation site is not greater than 10,000 feet.

•For copper connections on Ethernet ports, cable lengths from the switch to connected devices can be up to 328 feet (100 meters).

•For cable lengths for SFP-module connections, see the hardware installation guide on Cisco.com and the documentation that shipped with the module.
