Step 8—Check the Router Operation
1.
When power is supplied to the AirLink LX60 router, it powers up automatically, as
indicated by the flashing LEDs. If it does not turn on, ensure that the:
·
Power connector is plugged in and supplying voltage greater than 9 VDC.
Note: Although the LX60 operates in the range 7–36 VDC, low voltage standby mode is
enabled by default. In order to avoid the router powering on in standby mode, ensure that it is
supplied with more than 9 VDC at startup. (You can change the low voltage standby mode
settings once the router is operational. If the Power LED is red, the router is in standby mode.)
·
On/Off control (pin 3) is connected to the battery or power source (see
on page 16 for details).
