Maintenance and Troubleshooting 7-11
 Lightning Protection Module Check the lightning
protection module for lightning strikes (visible arcing),
damaged or poor connections, or corrosion. Replace a burned
out module, and repair any bad or corroded connections in the
wiring.
 Network Interface Box If any problems exist with the
network interface box, check the connectors to ensure that the
cable entries are tight and waterproof. If this does not resolve
the problem, contact the telephone company.
Note: Make sure both the lightning protection module
and network interface box are still waterproof.
