- I'm assuming power is at one of the cans, but don't know that for certain. I've moved wires around on the lower switch and got it to work, but then the upper switch would not turn lights off. Don't remember now what combination that was, but it had to have the white with 120 volts on it on one of the travelers. – Bruce Oct 9 '15 at 13:21.
- The steps to connect your system using a PoE switch are as follows: Connect an Ethernet cable from the LAN port on the PoE switch to your router. Connect the power cable to the PoE switch and to a power outlet or surge protector. Connect IP cameras to ports 18 on the PoE switch using the Ethernet extension cables. The PoE switch will provide.
- Last winter I pulled power into an attic. I put in a 2 gang box with 2 switches. One switch controls a light in the attic and works fine. The second controls an outlet and I realized months later that power is always on, the switch has no affect.
In a smart switch 3-way configuration, a smaller charge is looped through the add-on switch. Some things to know: 3-way wiring for smart switches is different than standard 3 way wiring. You cannot use dumb 3-way switches with smart switches (You must purchase the matching GE add-on switch to wire with your GE smart master switch).
PARTS AND MATERIALS
- 6-volt battery
- Low-voltage incandescent lamp (Radio Shack catalog # 272-1130 or equivalent)
- Long lengths of wire, 22-gauge or larger
- Household light switch (these are readily available at any hardware store)
Household light switches are a bargain for students of basic electricity. They are readily available, very inexpensive, and almost impossible to damage with battery power. Do not get “dimmer” switches, just the simple on-off “toggle” variety used for ordinary household wall-mounted light controls.

INSTRUCTIONS
Build a one-battery, one-switch, one-lamp circuit as shown in the schematic diagram and in the illustration.
This circuit is most impressive when the wires are long, as it shows how the switch is able to control circuit current no matter how physically large the circuit may be.
Measure voltage across the battery, across the switch (measure from one screw terminal to another with the voltmeter), and across the lamp with the switch in both positions.
When the switch is turned off, it is said to be open, and the lamp will go out just the same as if a wire were pulled loose from a terminal.
As before, any break in the circuit at any location causes the lamp to immediately de-energize (darken).

In addition to transmitting network data, a PoE Switch has a built-in Power over Ethernet injector to supply up to 100W Power over Ethernet (PoE) to standards-based 802.3af, 802.3at and 802.3bt compliant devices such as IP cameras, VoIP phones, and wireless access points. When connecting network devices, the switch will detect whether they are POE-compatible and automatically supply power. Using a PoE Switch saves on installation and maintenance costs by eliminating the need to install multiple pieces of equipment, additional electrical wires, and outlets.
Perle PoE Switches are classified as Layer 2 Power Sourcing Equipment (PSE). The industrial design of a Perle IDS PoE Switch, and all internal components, make it ideal for use in harsh environments subject to vibrations, extreme temperature fluctuations from -40C to 75C, and shocks such as:
