Step 4. Connect the Router to an AC Power
Source
The router comes with a built-in power supply and a standard power cable.
Instructions
1. Check to see that the power switch ( 0=off, 1=on ) on the rear of the
router is set off .
2. Connect the power cable (packaged with the router) to the AC power
connector on the back panel of the router and plug the other end into
an AC outlet.

will execute a Power-On-Self-Test (POST) when the unit is powered
on. During this test, channel lights will flicker. After successful
completion of the POST and boot of router software, the lights will
reflect ready status. Check the front panel of the router and you
should see that:
