The Tenda TEF1105P-4-63W is a 5 port 10/100 MBit/s desktop switch that does not require configuration and supports 4 ports of PoE. It automatically detects all IEEE 802.af/at compatible devices and supplies them with power. If you activate the "Ethernet Extension Mode", all 1-4 ports support autonegation 10M, full duplex and can be controlled separately. In this mode, the transmission range can be up to 250 meters. Here the power is transmitted together with the data in a single cable, allowing you to expand your network where no power is available. Perfect for e.g. access points, IP cameras or IP telephones.
