Rack-Mounting
This section covers basic 19-inch rack-mounting and switch port connections. The illustrations in this
section show the Catalyst 3550-12T and 3550-24 switch for examples. You can install and connect
other Catalyst 3550 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 3550 Multilayer 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 (3049 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 rear panel.
DC source wires can reach from the
–
circuit breaker to the terminal block plug
on the switch 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 cable lengths for Gigabit Interface
Converter (GBIC) modules, refer to the
documentation that shipped with the module.
