PES42P power source edge switch combines standard 802.3af Power over Ethernet (PoE) with a small, heavy duty, 6-port Ethernet switch

GarrettCom Europe has responded to the evolving needs of industrial applications that demand increased flexibility for edge networking with the launch of the PES42P hardened Ethernet edge switch. The new device provides connectivity for clusters of Ethernet-enabled devices, and combines this with fiber optic connectivity to the control network for high-bandwidth, secure data transmission.

Further, the PES42P is one of GarrettCom’s growing range of Power over Ethernet (PoE) switches, supplying power to connected devices and so eliminating the need for costly cabling back to a central power source. The list of PoE enabled equipment coming to the market is growing rapidly, and includes the likes of IP video surveillance cameras, wireless access systems, VoIP phones, badge readers and many others.

Compact, rugged, and hardened for harsh industrial environments and outdoor use, the PES42P edge switch provides a total of six Ethernet ports. Four ports are always RJ-45 for PoE. The remaining two ports can be user specified as two 100Mb fiber ports, or one fiber and one copper port, or two copper ports.

The ports which supply power feature an auto-sensing algorithm so that they provide power only to attached 802.3af PD devices. If proprietary PoE and non-PoE devices are attached, the auto-sensing feature ensures they will not be damaged. The PES42P ports discontinue supplying power when the PoE devices are disconnected, and support the PSE (Power Sensing Equipment) standard for over-current protection, under-current detection and fault protection.

The PES42P includes Link-Loss-Learn (LLL), enabling it to be used in self-healing and redundant LAN structures. PES42P Switches, combined with managed switches running STP or RSTP or S-Ring, can incorporate PoE devices and can provide high availability redundant LANs at lower total cost than was previously possible.

For users of modern, Ethernet-enabled video surveillance cameras, wireless access systems, VoIP telephones and other edge of network devices, the ability to drive these products via Power over Ethernet (PoE) from a compact network switch can be a key advantage. But much of that benefit is lost if the Ethernet switch itself requires a separate power supply before it can be connected into the mains. GarrettCom can overcome this with its IPS42 power supply chassis integrated add on for the PES42P hardened Ethernet edge switch.

This enables a single PES42P to power up to four PoE enabled devices from a single AC outlet, as well as a high-speed fiber media uplink to the control centre. This gives users far greater flexibility in deploying the likes of cameras, badge readers, VoIP phones, etc, reducing system complexity and overall panel space requirements.
