Switches
There are three ways to install the switch:
• Place the switch on a flat surface. To place the switch on a desktop,
install the four rubber feet (included) on the bottom of the switch.
• Mount the switch in a standard rack (1 rack unit high).
• Mount on a wall.
Placement Tips
Do not mount the device in a location where any of the following conditions
exist:
• High Ambient Temperature—To prevent the switch from overheating,
do not operate it in an area that exceeds an ambient temperature of
122°F (50°C).
• Air Flow—Both side panels must be unobstructed to prevent
overheating.
• Overloading—The device must be level, stable, and secure to prevent
it from sliding or shifting out-of-position.
• Circuit Overloading—Adding the device to the power outlet must not
overload that circuit.
Rack Mounting
You can mount the switches in any standard size, 19-inch (about 48 cm)
wide rack. The switch requires 1 rack unit (RU) of space, which is 1.75
inches (44.45 mm) high.
For stability, load the rack from the bottom to the top, with the

heaviest devices on the bottom. A top-heavy rack is likely to
be unstable and might tip over.
