1.3  Standby Mode (Power Saving Mode)
Your PLA is a certified green product. It goes into standby mode when there is no Ethernet 
connection.
When you plug the PLA into an electric socket, it waits for an Ethernet connection. When no 
connection is detected after sixty (60) seconds, the Power LED blinks indicating that it is going into 
standby mode.
The same process occurs when you disconnect the PLA from a previously working Ethernet 
connection. Sixty (60) seconds after disconnecting the Ethernet cable, the PLA’s power LED blinks 
signalling that it is going into standby mode.
The Ethernet and HomePlug LEDs are turned off in standby mode.
While in standby mode, you cannot use the RESET/ENCRYPT button. To enable the RESET/
ENCRYPT
 button again, you have to connect the PLA’s Ethernet cable to a computer/notebook or 
modem/router first. The PLA wakes up from standby mode and you can start using the RESET/
ENCRYPT
 button.
