Check the LEDs on the AT-MC606 front panel for proper operation. Refer 
to “AT-MC606 Front Panel” on page 16 for the LED locations and Table 3 
on page 21 for the LED functional descriptions.

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:

ˆ

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.

ˆ

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.

ˆ

Verify that the AC power outlet has power by connecting another 
device to it.

ˆ

Try connecting the AT-MC606 to another AC power source.

ˆ

Try using a different power cord or a different AC/DC power adapter.

ˆ

Check that the voltage from the power source is within the required 
levels for your region.
