Power LED
Check the PWR LED on the front of the AT-MC606 VDSL Network
Extender. If the LED is OFF, indicating that the AT-MC606 is not receiving
power, do the following:
 If the AT-MC606 is inserted in the AT-MCR12 rackmount chassis,
make sure that the power cord is securely connected to the power
source and to the power connector on the back panel of the
AT-MCR12 rackmount chassis.
 If the AT-MC606 is in a stand-alone configuration, make sure that the
AC/DC power adapter is securely connected to both the power source
and the DC power connector on the back panel of the AT-MC606.
 Verify that the AC power outlet has power by connecting another
device to it.
 Try connecting the AT-MC606 to another AC power source.
 Try using a different power cord or a different AC/DC power adapter.
 Check that the voltage from the power source is within the required
levels for your region.
