Chapter 2 Installing the Utility
When you plug the PLA4215 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
Low Power mode.
The same process occurs when you disconnect the PLA4215 from a previously working Ethernet
connection. Sixty (60) seconds after disconnecting the Ethernet cable, the PLA4215's Power LED
blinks signalling that it is going into Low Power mode.
The Ethernet and HomePlug LEDs are turned off in Low Power mode.
While in Low Power mode, you cannot use the ENCRYPT button. To enable the ENCRYPT button
again, you have to connect the PLA4215's Ethernet cable to a computer/notebook or modem/router
first. The PLA4215 wakes up from Low Power mode and you can start using the ENCRYPT button.
Low Power mode is enabled by default.
