Installation
Site Requirements
Ventilation
The AT-MR420T/AT-MR820T Micro Repeaters have grilled openings
on both sides for ventilation. Although these micro repeaters do not
require an internal fan, adequate ventilation is required.
Note
Make sure that the ventilation openings located on the sides
of the chassis are never blocked. Maximum ambient
temperature is 104
o
F (40
o
C).
Power
Be sure that the voltage and frequency is 100-120 or 200-240 VAC and
60 or 50 Hz respectively. Because there is no external power switch,
power is applied when the power cord is connected.
Note
For countries other than the United States and Canada: use a
power cord that is rated at 6 amp, 250 VAC. Also note that this
cord cannot exceed 4.6 meters (15 ft.) and must be made of
HAR cordage with IEC fittings that are approved by the
country of end use.
Quick Installation
If you are experienced with electronic networks in general and
repeaters in particular, use the following procedure. If you are not
