Setting up the Switch
The site where you install the switch may greatly affect its performance. Please follow these
guidelines for setting up the switch.
z Install the switch on a sturdy, level surface that can support at least 6.6 lb. (3 kg) of
weight. Do not place heavy objects on the switch.
z Ensure that the power outlet is within 1.82 meters (6 feet) of the switch.
z
Visually inspect the power cord and see that it is fully secured to the AC power port. See
Section “Connecting the Switch to a Power Supply.”
z
Make sure that there is proper heat dissipation from and adequate ventilation around the
switch. Leave at least 10 cm (4 inches) of space at the front and rear of the switch for ven-
tilation.
z Install the switch in a fairly cool and dry place for the acceptable temperature and humid-
ity operating ranges.
z Install the switch in a site free from strong electromagnetic field generators (such as
motors), vibration, dust, and direct exposure to sunlight.
z When installing the switch on a level surface, attach the rubber feet to the bottom of the
device. The rubber feet cushion the switch, protect the casing from scratches, and prevent
it from scratching other surfaces.
Connecting the Switch to a Power Supply
1. Connect one end of the AC power cable to the AC power connector located on the back panel (see
Figure 2) and the other end into the local power source outlet.
NOTE:
Do not connect the power cable to a grounded AC outlet at this time. Connect the
switch to a power source as described in the step detailed in “Starting and Configur-
ing the Switch” on page 23."
