A.

If the web monitoring system notice you that particular AC modules are not communicating with the 
EnerBox2, then write down the location of the AC module and MAC address.

B.

Find out the physical location of the target AC modules. Please make sure that you are equipped with 
proper gears that can protect you.

C.

During a daytime, check whether the LED blinks red or shows no lights. And keep the LED status in mind 
or write it down on your notes.
