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.
