ZyXEL Communications PLA SERIES User Manual

PLA Series User’s Guide

This chapter offers some suggestions to solve problems you might encounter. 

The PLA does not turn on. None of the lights turn on.

Disconnect and re-connect the PLA. 

Remove the powerline adapter from the outlet. Then connect an electrical device that you know 
works into the same power outlet. This checks the status of the power outlet.

If the problem continues, contact the vendor.

The ETHERNET light does not turn on.

Check the hardware connections. See the Quick Start Guide.

Inspect your cables for damage. Contact the vendor to replace any damaged cables.

Check the Ethernet adapter on your computer and make sure it’s enabled and working properly. 

If the PLA is connected to an Ethernet switch or router, make sure the device is working correctly, 
and that the LAN network is working and configured correctly as well. 

The HomePlug light does not turn on.

Use the ZyXEL PLA Series Configuration utility to detect all other HomePlug devices on your 
powerline network. Make sure that the network name (sometimes called the network password) is 
the same on all of your powerline adapters. See 

 for instructions on 

changing the network name. 

Check the DAK password and MAC address for all powerline adapters are typed correctly in the 
utility. See 

 for instructions on checking the DAK and MAC address.
