Industrial Power over Ethernet (PoE) switch
4 x RJ45, 4 x PoE | PS14 series GarrettCom Europe

The PS14 PoE Power Source Convenient Switch combines standard 802.3af Power over Ethernet (PoE) with a small heavy-duty 4-port Switch. Using an external -48VDC power source, all four of the PS14's Ethernet ports can provide power as well as 10/100 Mb data transmission over the inter-connecting Ethernet cables. Now, data and power for attached devices can be transmitted over a single Ethernet twisted-pair cable.

The PS14 switches are Power Sourcing Equipment (PSE), and are fully compatible with Powered Devices (PD) that comply with the IEEE 802.3af PoE standard. The PS14 Switch ports have an auto-sensing algorithm so that they provide power only to attached 802.3af end devices. If proprietary PoE and non-PoE equipment is attached, it will not be damaged. The PS14 ports discontinue supplying power when the PoE (PD) devices are disconnected, and support the PSE standard for over-current protection, under-current detection and fault protection.

The PS14 is a standards-compliant way to power and connect a few small Ethernet devices at the edge of a network where AC power is either not available or not cost-effective. Increasingly, small powered devices (PD) such as IP phones, video cameras, wireless access points, digital clocks, special purpose radios, IP phones, industrial sensors and laptop computers benefit with increased installation flexibility from the PS14's PoE-PSE capabilities. Traditionally, a mid-span patch panel device could have been connected to a standard Ethernet switch, and insert power onto a PD device -- a configuration requiring two devices to achieve PoE.
