Installation
This section describes the installation and functionalities of the POC extender’s
components. Basic knowledge of networking is assumed. Please read this chapter
completely before continuing.
Note: Before installation, consider the distance and Watt value demand for PD devices.
The POC extender output capacity and upload/download performance depends on the
length of the coaxial and UTP cables.
Note: When the remote PD's total power consumption is higher than the POC
extender's PoE power budget, the device will reboot and the LED Indicators will flash
continuously. Remove UTP cables from the RJ45 ports to avoid malfunctioning of the
POC extender.
Installation precautions
The POC extender supports two ways as power source to inject 802.3af/at PoE to
remote standard PDs.
• Remote POC power from POC injector/switch over coaxial/UTP cable.
• Local DC power from power supply through the POC extender’s terminal block.
Remote power by coaxial cable
When installing POC PoE over coaxial injector, it only can work with the POC2052-4P-
1CX POC extender. Confirm that other non-PoE equipment is not connected with the
coaxial cable. When you connect the coaxial cable to a coax-LAN converter, CCTV
camera, and so on, it might damage the other equipment.
Caution: After the power over coaxial injector is enabled, the center pin of the coaxial
cable is with electricity. Please do not touch the center pin.
