Grounding shielded network cables
Using shielded network cables can improve surge protection performance of the AP. To
ground a shielded network cable, perform the following operations:
1.
Remove the shield layer of the shielded network cable.
2.
Connect the cable to the ground clip.
3.
Wrap the cable with waterproof and ESD tapes.
NOTE
l
When wrapping the waterproof tape, stretch the tape evenly until the tape turns twice its original
length.
l
Wrap each layer of tape tightly and neatly, and ensure that each layer of tape overlaps more than
50% of the preceding layer.
l
Ensure that the side with adhesive tape is covered on the wrapped tape.
l
When cutting off the cable tie, reserve an extra length of 3 mm to 5 mm.
2.6.4 Installing Outdoor Antennas
Two types of outdoor antennas are available: directional outdoor antenna and omnidirectional
outdoor antenna. Omnidirectional antennas can be directly installed on APs.
Installing a Directional Outdoor Antenna Against a Pole
Pay attention to the following points when installing a directional antenna:
1.
An outdoor antenna must be installed on a pole with a diameter of 30 mm to 50 mm and
the thickness must be at least 2.5 mm. A 50 mm diameter pole made of round steel is
usually used.
2.
Weld the lightning rod on the top of the antenna pole.
3.
Install the antenna pole on a parapet or concrete bed on the roof of the building.
4.
Use a 40 mm x 4 mm flat steel to connect the antenna pole to an earth mat.
5.
Secure the directional outdoor antenna on the pole with an antenna support.
