For 100 megabit PoE switches, it could use a 4-core cable (1,2,3,6) to transmit both data and power supply. Also, you must ensure that all eight cores are. There are two common standards for standard PoE switches, IEEE 802. 3at, both of which support two power supply methods. Data runs over 1236 and power supply runs over 4578 In current market, the PoE cameras support both of these two. All Ansice IP cameras adopt the standard 48V to 12V POE, and both 1236 and 4578 POE power supply modes are supported. The standard 48V POE power supply is powered by 1236, which not only transmits data, but also supplies power. Two power supply solutions for POE-The POE standard defines two methods for transmitting DC power to POE-compatible devices using Ethernet transmission cables: One is called "Mid-Span", which uses idle pairs that are not used in the Ethernet cable to transmit DC power (that is, 1236 line sequence. lients and other high power Ethernet end terminals. The 4578 cores are defined as "" spare" Then, if you want to use only the 1236 four cores of the network cable, and use the network to supply power at the same time, you need to confirm which. The manageable industrial-switch offers eight 10/100/1000Base-T copper connections and two SFP slots for fiber optics, with a power supply of 12 or 24 volts and is therefore suitable for installation in vehicles (e.
