G1105P-4-63W is a IP-COM PoE switch that offers 5 10/100/1000 Mbps Base-TX RJ45 ports. Ports 1-4 comply with the IEEE 802.3af standard (maximum PoE power output: 15.4 W) and 802.3at standard (maximum PoE power output: 30 W). The switch offers a maximum PoE power output of 58 W and can supply power to and exchange data with APs, IP cameras, and IP phones through CAT5 cables. It also provides simple management modes such as VLAN, to help reduce cabling costs of IP terminals like APs and IP cameras. Lightning Protection 6KV The ports and embedded power can provide lightning protection of up to 6kV. It also provides PSE shortcircuiting protection, PoE overloading, power over temperature, over voltage and surge current protection. 58W PoE power supply Ports 1-4 comply with the IEEE802.3af and IEEE802.3at power supply standards. The entire switch offers a maximum PoE power output of 58W, whereas each port offers a maximum PoE power output of 30 W. The ports can be used to supply power to and exchange data with APs and IP cameras. One-Key VLAN If "vlan mode" is enabled, Port 1-4 will be isolated respectively but can communicate with the 5 port. Hardware DIP switch to isolate ports to prevent broadcast storm and defend against DHCP spoofing.
