2. Using a CAT-5e cable, connect the PoE injector to he
ETH/PWR
port on the subscriber station.
3. Connect a CAT-5e cable between the Ethernet switch and the PoE injector.
IMPORTANT!
The AC power cable must meet the following specifications:
• Consist of 3 wires
• Minimum 18 AWG
• Less than 4.5 m (14.7 ft) long
• Safety certified according to national rules
4. Connect the open-ended AC power cable to the power supply unit.
Section 2.9
Weatherproofing the Subscriber Station
Most outdoor subscriber station, antenna and cable problems are caused by coaxial cable connections loosened by
vibration, allowing moisture to penetrate the connector interface. Siemens strongly recommends weatherproofing
all
outdoor cable connections to prevent the ingress of water and help secure connections.
Since PoE cables also carry DC current, the need for proper weatherproofing cannot be overstated.
Use cold shrink tubing or self-amalgamating tape, as well as UV-resistant tape and electrical insulation putty to
seal connections.
IMPORTANT!
Warranty is void if the subscriber station is assembled without waterproof sealing or if the sealing is
removed from the connections.
