Introduction

Power over Ethernet Industrial Ethernet Fibre Switch

Features

The Magnum PES42P PoE Power-Source Edge Switch combines standard802.3af Power over Ethernet (PoE) with a small heavy-duty 6-port Ethernet Switch.Using an external -48VDC power source, four of the PES42P's Ethernet ports canprovide power as well as 10/100 Mb data transmission over the inter-connectingEthernet cables. Data and power for the attached devices can be transmittedover a single Ethernet twisted-pair cable to each, simplifying and cost-reducinginstallation and maintenance in an industrial facility. The other PES42P ports may be 100Mb fiber for distance, noise immunity, ground-isolation and high bandwidth.

The compact PES42P Edge Switch design delivers 6 Ethernet ports. Fourports are always RJ-45 for PoE. The PES42P base models have either two 100 Mbfiber and 4 10/100 PoE copper ports, or one fiber and five copper ports, or 6copper ports, 4 of which are PoE.

The PES42P switches are Power Sourcing Equipment (PSE), and are compatiblewith Powered Devices (PD) that comply with the IEEE 802.3af PoE standard.The PES42P Switch ports have an auto-sensing algorithm so that theyprovide power only to attached 802.3af PD devices. If proprietary PoE and non-PoE equipment is attached, it will not be damaged. The PES42P ports discontinuesupplying power when the PoE devices are disconnected, and support thePSE standard for over-current protection, under-current detection and fault protection.

The PES42 includes Link-Loss-Learn (LLL), enabling it to be used in selfhealingand redundant LAN structures. The LLL feature causes PES42P Switchesto sense Link Loss or standard STP / RSTP reconfiguration signals on designatedports, flush internal address buffers to permit a change in LAN packets flow, andpass the reconfiguration signal down the line to other products in the redundantnetwork structure. Magnum PES42P Switches, combined with managed switchesrunning STP or RSTP or S-Ring, can incorporate PoE devices and often providehigh availability redundant LANs at lower total cost than was previously possible.

The PES42P is a standards-compliant way to power and connect IndustrialEthernet devices at the edge of a network where AC power is either not availableor not cost-effective. Increasingly, small powered devices (PD) such as IP phones,video cameras, wireless access points, digital clocks, special purpose radios, industrialsensors and laptop computers benefit from increased installation flexibilityvia the PES42P's PoE-PSE capabilities. Traditionally, a mid-span patch paneldevice could have been connected to a standard Ethernet switch, and insert poweronto a PD device - a configuration requiring two devices to achieve PoE. ThePES42P integrates fiber media upstream connectivity with an industrial Ethernetswitch and the PoE power functions into one unit, saving cost and space, andincreasing reliability for the application.The PES42P Edge Switch comes with two (2) sets of LED indicators. Oneset is on the front for viewing convenience when the unit is DIN-Rail or wallmounted,and one LED set is mounted in the end adjacent to the ports for easyviewing when units are in a rack-mount tray. The Magnum PES42P and otherMagnum products are designed and manufactured in the USA and backed by athree-year warranty.
