Site Requirements
Before installing AT-30xxTR repeaters, read the electrical safety and
installation requirements starting on page i.
If the installer is experienced with the AT-30xxTR repeater and does not
need detailed installation instructions, refer to Quick Installation Checklist in
Chapter 1 of this manual.
Ventilation AT-30xxTR multiport 10BASE-T repeaters have vents on the sides for air
circulation. Do not restrict the flow of air through these openings.
Obstructing the passages may cause overheating and possible component
damage.
Power Check your network cabling for proper configuration before installing the
repeater. Make absolutely sure that the voltage and frequency applied are of
the correct values for your AT-30xxTR.
The AT-30xxTR is equipped with an universal power supply that will accept
either 100-120 or 200-240 VAC power at 50 or 60 Hz as appropriate.
There is no external power switch for AT-30xxTR model repeaters. Power is
applied as soon as you connect the power cord. Make sure that you locate the
unit near an easily accessible AC outlet so that you can easily disconnect the
power cord.
Port Configurations

receptacles equipped with shielded RJ45 connectors. The model number
indicates the number of station ports, as shown in Table 1 on the following
page. The layout and numbering of the ports varies depending on the model
