• Industrial PoE Edge Switch with 100Mb fibre ports and 4 Power-Sourcing RJ-45 PoE ports per IEEE 802.3af
• Ideal for PoE used in industrial IP video surveillance, wireless-access, VOIP phones, badge readers and support of similar hardened PoE devices
• “Outdoor” temperature rating handles heavy duty applications
• Includes Link-Loss-Learn (LLL) feature for use in selfhealing LAN structures
• Packaging and mounting options are similar to the popular ES42-Series Edge Switches

The PES42 PoE Power-Source Edge Switch combines standard 802.3af Power over Ethernet (PoE) with a small heavy-duty 6-port Ethernet Switch. Using an external -48VDC power source, four of the PES42’s Ethernet ports can provide power as well as 10/100 Mb data transmission over the inter-connecting Ethernet cables. Data and power for the attached devices can be transmitted over a single Ethernet twisted-pair cable to each, simplifying and cost-reducing installation and maintenance in an industrial facility. The other PES42 ports may be 100Mb fibre for distance, noise immunity, ground-isolation and high bandwidth.

The compact PES42 Edge Switch design delivers 6 Ethernet ports. Four ports are always RJ-45 for PoE. The PES42 base models have either two 100 Mb fibre and 4 10/100 PoE copper ports, or one fibre and five copper ports, or 6 copper ports, 4 of which are PoE. The PES42 switches are Power Sourcing Equipment (PSE), and are compatible with Powered Devices (PD) that comply with the IEEE 802.3af PoE standard.

The PES42 Switch ports have an auto-sensing algorithm so that they provide power only to attached 802.3af PD devices. If proprietary PoE and non- PoE equipment is attached, it will not be damaged. The PES42 ports discontinue supplying power when the PoE devices are disconnected, and support the PSE standard for over-current protection, under-current detection and fault protection.

The PES42 includes Link-Loss-Learn (LLL), enabling it to be used in self-healing and redundant LAN structures. The LLL feature causes PES42 Switches to sense Link Loss or standard STP / RSTP reconfiguration signals on designated ports, flush internal address buffers to permit a change in LAN packets flow, and pass the reconfiguration signal down the line to other products in the redundant network structure. PES42 Switches, combined with managed switches running STP or RSTP or S-Ring, can incorporate PoE devices and often provide high availability redundant LANs at lower total cost than was previously possible.

The PES42 is a standards-compliant way to power and connect Industrial 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, industrial sensors and laptop computers benefit from increased installation flexibility via the PES42’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. The PES42 integrates fibre media upstream connectivity with an industrial Ethernet switch and the PoE power functions into one unit, saving cost and space, and increasing reliability for the application.

The PES42 Edge Switch comes with two sets of LED indicators. One set is on the front for viewing convenience when the unit is DIN-Rail or wall mounted, and one LED set is mounted in the end adjacent to the ports for easy viewing when units are in a rack-mount tray. The PES42 and other products are designed and manufactured in the USA and backed by a three-year warranty.
