1.2 About the Power over Ethernet Injector The POE-151 is an IEEE 802.3af Power over Ethernet Injector that provide DC 48V over Ethernet cables. The POE-151 IEEE 802.3af Power over Ethernet Injector inserts DC Voltage into Cat.5 cable, allowing the cable between the Injector (POE-151) and Splitter (POE-151S-5V/9V/12V) to transfer data and power simultaneously.
73 x 55 x 24 mm FCC Class B, CE mark IEEE 802.3 Ethernet, IEEE 802.3u Fast Ethernet, IEEE 802.3af Power over Ethernet. Function Lights to indicate that the POE-151 has power. Lights to indicate the port is providing 48VDC in-line power. - 5 -...
POE-151 can provide you a way to supply power for this Ethernet device conveniently and easily. The POE-151 equips with an AC-DC adapter with DC 48V input and injects this DC power into the pin of the twisted pair cable (pair 1, 2 and pair 3, 6 for Fast Ethernet).
2.3 POE-151 and POE-151S, the IEEE 802.3af Injector and Splitter installation 1. Connect a standard network cable from “Ethernet+DC” of POE-151 to “Ethernet+DC” of POE-151S. The POE LED of POE-151 / POE-151S will light on continuance. The screen in Figure 2 appears.
VoIP phones and Internet camera where support IEEE 802.3af In-line Power over Ethernet port. The screen in Figure 4 appears. Once POE-151 detects the existence of an IEEE 802.3af device, the LED indicator will be steady, ON to shows it is- providing power.
Solution: The POE-151 use 4-wire for data transmission (pair 1, 2, pair 3, 6) and 4-wire for power supply (pair 4, 5, pair 7, 8), thus Gigabit Ethernet device connect to POE-151 will not send data over the power wire and the transmit speed shall change to 100Mbps.
7, 8 Remark: Gigabit Ethernet is not allowed to use POE-151 since pair 4,5 and pair 7, 8 are all being used for data transmission in Gigabit Ethernet data transmission. Only 10Base-T and 100Base-TX can apply with POE-151 products. A.2 RJ-45 cable pin assignment The standard RJ-45 receptacle/connector There are 8 wires on a standard UTP/STP cable and each wire is color-coded.
