Nokia RoofTop™ Wireless Router Installation Guide
4.2.3 Finding a location for the NPU
The Network/ Power Unit is plugged into a grounded AC outlet. When
locating the AC outlet consider the following:
•
Try to find a place in close proximity to the place where the multiwire
cable enters the house.
4.2.4 Planning the cable routing
The multiwire cable runs from the outside of the house to the inside so be
aware that outside weather plays a factor. The maximum length of the
multiwire cable that Nokia provides is 150ft. In any case the cable should
be routed so that the length of the cable is minimized.
•
Where possible, route the cable inside wall or roof spaces. Try to
avoid drilling holes through the wall.
•
Avoid air ducts, water, and gas pipes.
•
Where wires have to be routed outside the building, make sure they
are supported with cable clips at 18 to 24 inch intervals.
•
Seal any drill holes in the wall using silicone sealant.
•
If HomePNA is used, the cable can enter the house anywhere, where
it is close to a phone jack. This will allow you to shorten the distance
you have to route the cable. HomePNA uses the existing phone lines
in the house, so when considering the entrance of the cable or the
location of the NPU, you only need to make sure that they are close to
a phone jack.
4.2.5 Finding a location for the grounding
Test the existing grounding at the property.
•
Try to find an electrical ground close to the cable entrance.
