PoE (Power over Ethernet)
12Vdc @ 1.75A (20 Watt) Splitter
Installation Guide
Purpose of this Guide
This Guide provides information and procedures for the product installation and operation of the PoE
12Vdc Splitter (LP-4812). This document is intended for technical personnel responsible for installing and
operating Power over Ethernet products in a Local Area Network (LAN) environment. To use this
document effectively, you should have a working knowledge of Local Area Networking (LAN) concepts and
hardware installation. In addition, you should be familiar with the following: Connection of Patch Cables
with RJ45 connectors and the LAN addressing map for your particular Network, Mounting of Network
hardware in a 19” equipment rack and local practices for power cord connections.
IMPORTANT SAFETY INSTRUCTIONS FROM LAN-Power
Read and keep these instructions. Follow all instructions and heed all warnings. Do not use this
equipment near water and clean only with a dry cloth. Do not block any equipment ventilation openings.
Install in accordance with manufacturer’s instructions. Do not install near any heat sources such as
radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. Do not defeat
the safety purpose of the polarized or grounding-type plug. Unplug this equipment during lightning storms
or when unused for long periods of time. Refer all servicing to qualified service personnel. Servicing is
required when the equipment has been damaged in any way, such as power cord or plug damaged, liquid
has been spilled, or object has fallen into the equipment, the equipment has been exposed to rain or
moisture, does not operate normally, or has been dropped. The AC mains outlet, or appliance coupler
shall be readily available to the operator as a means of power disconnection.
WARNING
- Only connect equipment to mains power outlet having protective earthing or grounding
connection. To reduce the risk of fire or electric shock, do not expose this equipment to rain or moisture.
CAUTION
– These servicing instructions are for use by qualified service personnel only. To reduce the risk
of electric shock, do not perform any servicing other than that contained in the operating instructions
unless you are qualified to do so.

etc...). The type of End device being powered including Manufacturer name and part number. Powering
requirements of the End device. A description of your Network environment (layout, Ethernet switch
description, cable type, etc...). The unit history (i.e., have you returned the unit before, is this a recurring
problem, etc...)
Please note only qualified personnel should install this unit and
read instructions before attempting to install this unit
Verifying Contents of Package
- Unpack the PoE Injector and verify that you have the
following item: LP-4812 Power over Ethernet 12Vdc Splitter
Technical Considerations
-
Before you mount the Splitter to a fixed location, consider all of the following:
Determine optimal placement, checking all cable paths and routing. Collect and document Network
information as required.
Notes:
1.)
The Splitter is not a repeater and does not amplify the Ethernet data
signal. Ensure the cable length from the Ethernet Network Switch to the Powered End device does not
exceed 328 feet/100 meters total length. 2.) The Splitter must be used in conjunction with a PoE
compliant PSE (Power Supply Equipment) such as a PoE Midspan Injector with a
Minimum Output of 25
Watts
to achieve full power output of 12Vdc @ 1.75Amps (20 Watts) from the LP-4812 Splitter.
