Connecting the antenna cables
The antenna cables connect the antenna ports (2.4 GHz and 5 GHz) to the outdoor antennas.
To connect the antenna cables:
1.
Connect the antenna cables to the antenna ports of the AP at one end and to the outdoor
antennas at the other end.
Connect the cables to the 2.4 G-1/2 and 5G-1/2 antenna ports on the AP.
Figure 18 Connecting the antenna cables to the AP antenna ports
2.
Wrap the connections with insulating tape and apply several layers of waterproof sealing tape
over the insulating tape.
NOTE:
•
When connecting the antenna cable to an AP, antenna, coupler, or power divider, make sure the cable
remains straight for a minimum of 5 cm (1.97 in) out of the connector.
•
Prepare an antenna arrestor yourself if required.
•
Make sure that the grounding cables are reliably grounded during outdoor deployment.
•
You can order the standard ready-made antenna cables, or order cables of desired lengths and N-type
antenna connectors and make antenna cables on-site as needed.
•
Test the Voltage Standing Wave Ratio (VSWR) of the antenna connectors and cables made on-site. The
cable reflectivity on the working channel must meet the requirements of the AP and the engineering design.
•
Stretch the waterproof sealing tape till the width of the tape is reduced to 3/4 of the original width and wrap
the waterproof sealing tape around the cable to achieve desired waterproof performance.
Connecting the fiber cable
CAUTION:
•
To avoid AP damage, follow the procedure when connecting the fiber cable.
•
When a fiber cable is used to transmit data, both ends of the cable must use appropriate SFP transceiver
modules. The SFP transceiver modules provided by H3C meet the outdoor deployment requirements, use
single mode fiber, and have a transmission distance of 15 km (9.32 mi).
