Rack-Mounting

This section covers basic 19-inch rack-mounting and switch port connections. As an example, all the

illustrations show the Catalyst 2950G-48-EI switch. You can install and connect other Catalyst 2950

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, refer to the

Catalyst 2950 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 (3,049 m).

• 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 front or rear panel.

DC source wires can reach from the

–

circuit breaker to the terminal block plug

on the switch front or rear panel.

• 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 100BASE-FX ports, the cable length from

a switch to an attached device cannot exceed

6562 feet (2 kilometers).

• For 1000BASE-SX ports, the cable length

from a switch to an attached device cannot

exceed 1804 feet (550 meters).

• For cable lengths for small form-factor

pluggable (SFP) modules or Gigabit Interface

Converter (GBIC) modules, refer to the

documentation that shipped with the module.

• For cable lengths for LRE switch ports, refer

to the Catalyst 2950 Switch Hardware

Installation Guide.
