If the heartbeat(HB light) is visible, the Commander has power.
If the HB light is Off, proceed to Step 2.
Go to the back of the Commander.
Find A/C Input 1.
Make sure the power cord is fully plugged into A/C Input1.
Trace the same power cord to the UPS or wall outlet.
Make sure that end is fully plugged in too.
The Commander should stay plugged into a UPS. This protects the unit and helps provide stable voltage.
