6 Rack-Mounting This section covers basic 19-inch rack-mounting and switch port connections. As an example, all the illustrations show the Catalyst 3750G-48TS switch. You can install and connect other Catalyst 3750 switches as shown in these illustrations. 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 Catalyst 3750 Switch Hardware Installation Guide on Cisco.com. Equipment That You Supply You need to supply a number-2 Phillips screwdriver to rack-mount the switch. Before You Begin When determining where to install the switch, verify that these guidelines are met: • Airflow around the switch and through the vents is unrestricted. • Temperature around the switch does not exceed 113°F (45°C). • Humidity around the switch does not exceed 85 percent. • Altitude at the installation site is not greater than 10,000 feet. • Clearance to the switch front and rear panels meets these conditions: - Front-panel LEDs can be easily read. - Access to ports is sufficient for unrestricted cabling. - AC power cord can reach from the AC power outlet to the connector on the switch rear panel. - Access to the rear of the rack is sufficient for connecting StackWise cables to stacked switches. • Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent lighting fixtures. • For 10/100 ports and 10/100/1000 ports, the cable length from a switch to an attached device cannot exceed 328 feet (100 meters). • For cable lengths for small form-factor pluggable (SFP) modules, see the documentation that shipped with the module. • For cable lengths for XENPAK modules, see the documentation that shipped with the module. 13
