The HyperLink BT-CAT5-P1-4870 Single-Port CAT-5 Midspan/Injector kit (also known as PoE Passive Splitter) is a commercial grade Power-over-Ethernet device that provides DC power for one PoE-equipped device. It is compatible with AP’s and other equipment supporting the IEEE standard PoE pinout (Pins 4&5 Power + / Pins 7&8 Power -).<br><br>Power-over-Ethernet eliminates the need for an AC outlet at each AP location. Only a single Ethernet cable is run to each AP instead of separate power and data cables. The injector is typically installed near the Ethernet hub.<br><br>This unit can be used as either an "Injector" or as a "Tap". When used as an injector the device sends DC power through the Ethernet cable to a remote PoE device. When used as a "Tap" this unit taps the injected DC power from the Ethernet cable for use by certain non-PoE devices.<br><br> Integral Surge Protection<br><br>The integral lightning and surge protection individually protects the 4 data lines as well as protection for the power lines. High speed devices clamp any voltage, positive or negative on the wires. The limits are +/- 15 volts on pins, 1, 2, 3, 6 and +/- 58 volts on pins, 4, 5, 7 and 8.<br><br>The BT-CAT5-P1-4870 features shielded RJ45 jacks. This along with the BT-CAT5-P1's metal housing helps reduce the effects of EMI interference. A ground lug and terminal is provided directly on the injector housing providing superior grounding. The cast aluminum housing includes integral mounting fe |
