Is there power going to the unit?
Check the following:
- Check electrical supply. Plug the power cord’s 2-pronged plug into a wall outlet. The Status LED (A) will glow amber if power is present.
- Check to see if there is a switch controlling the wall outlet. If there is, make sure it's in the "on" position.
- Check to see if the household fuse or circuit breaker has tripped or blown. Reset a tripped breaker or replace any blown fuses.
