V The HomePlug light does not turn on.
1 Check 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 44 for instructions on installing the latest firmware.
2 Use 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 43 for instructions on checking the network name.
3 Check the DAK password and MAC address for all powerline adapters are typed
correctly in the utility. See Section 5.3 on page 43 for instructions on checking the DAK
and MAC address.
4 Make 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.)
5 Make 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.
6 If your powerline network is using coaxial cable, check all powerline adapters are on the
same coaxial cable.
7 If 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.
V The POWER and HomePlug light blink at the same time.
• You have pressed the ENCRYPT button for more than three seconds. Try setting up a
connection again, this time pressing the ENCRYPT buttons on both devices for less than
three seconds.
