Chapter 7 LEDs and Troubleshooting

The ETHERNET light does not turn on.

1Check the hardware connections. See the Quick Start Guide.

2Inspect your cables for damage. Contact the vendor to replace any damaged cables.

3Check the Ethernet adapter on your computer and make sure it’s enabled and working properly.

4If the PLA-4xx 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.

1Check all PLA-4xxs on your network have the latest firmware installed. PLA-4xxs with the latest firmware cannot communicate with PLA-4xxs using earlier versions of the firmware. Go to Section 5.4 on page 48 for instructions on installing the latest firmware.

2Use the PLA-4xx 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 Section 5.3 on page 47 for instructions on checking the network name.

3Check the DAK password and MAC address for all powerline adapters are typed correctly in the utility. See Section 5.3 on page 47 for instructions on checking the DAK and MAC address.

4Make sure that all your powerline adapters are HomePlug AV compliant. Check the package it came in or ask your vendor. This PLA-4xx can not detect earlier versions of HomePlug powerline adapters such as HomePlug 1.0 or 1.0.1. (Although they can coexist on the same electrical wiring without interfering with each other.)

5Make sure that the powerline adapters on your network are all on the same electrical wiring. Connect another powerline adapter into an outlet close to your PLA-4xx’s power

outlet. They are probably now on the same electrical wiring. Check the HomePlug light. If it now lights up your powerline adapter was probably previously on separate electrical wiring. Ask an electrician for more information on the electrical wiring in your building.

6If your powerline network is using coaxial cable, check all powerline adapters are on the same coaxial cable.

7If your powerline network is using electrical wiring (not coaxial cable), check you do not have a power meter between powerline adapters. Powerline signals cannot pass this.

The POWER and HomePlug light blink at the same time.
