Before You Begin
When you determine where to install the switch, follow these guidelines:
• Airflow around the switch and through the vents is
unrestricted. Allow at least 3 inches (7.6 cm) of clearance
around the ventilation openings. Do not stack switches,
and do not place the 8- or 12-port switches side-by-side.
• When you place the 8- or 12-port switch on a flat
horizontal surface without the magnet, attach the rubber
feet to the switch to prevent airflow restriction and
overheating.
• Allow at least 1.75 inches (4 cm) of clearance above each
8- or 12-port switch in the rack.
• Wall-mount the 8- or 12-port switch with its front panel
facing down to prevent airflow restriction and to provide
easier access to the cables.
• Do not place any items on the top of the switch.
• Clearance to the switch front and rear panels meets these
conditions:
You can easily read the front-panel LEDs.
–
Access to ports is sufficient for unrestricted cabling.
–
The power cord can reach from the power outlet to
–
the connector on the switch rear panel.
Rack-Mounting the Switch (Catalyst 3560 24- and 48-Port Switches)
This section applies to the Catalyst 3560 24- and 48-port switches. For the Catalyst 3560 8- and 12-port switches, see "Securing
the Switch on a Desk or Shelf (Catalyst 3560 8- and 12-Port Switches)" section on page 13 and "Mounting the Switch with a
Magnet (Catalyst 3560 8- and 12-Port Switches)" section on page 14.
This section covers basic 19-inch rack-mounting. The Catalyst 3560G-48PS switch is shown as an example. You can install and
connect other 24- and 48-port Catalyst 3560 switches as shown.

• 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.
• The heatsinks and the bottom of the 8- or 12-port switch
might be hot to the touch if the switch is operating at its
maximum temperature 113°F (45°C) in an environment
that exceeds normal room temperature (such as in a closet,
in a cabinet, or in a closed or multirack assembly).
• 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.
