For the best protection, two instances of the lightning protection device should be used. Use
lightning protectors that are recommended by Alvarion.
1. Position one of the lightning protection devices as close to the building entrance as
possible and connect it to the grounding bar of the building.
2. Position the second lightning protection device as close to the base station as possible
and connect it to the tower/pole ground plate using a short 10 AWG cable.
3. Ensure that the tower/pole has a lightning rod connected to the earth with a down-
conductor.
Note: Use only shielded CAT5e/6 cables for the POE connection.
4. Ensure that the cable shield is firmly connected (soldered) to the RJ45 plug shield. Non-
shielded cables or non-shielded RJ45 plugs will not provide any grounding points or
protect from static discharge or lightning strike
Note: Lightning damage is not covered under the Alvarion Warranty.
When correctly installed, the recommendations on this page offer you the best protection
from the harmful effects of lightning. However, 100% protection is neither implied nor
possible.
