GarrettCom Europe slashes the cost of power over Ethernet

04 May 2010

Rugged, affordable Ethernet switches provide a convenient means of expanding network infrastructures.

GarrettCom Europe has slashed the cost of Power over Ethernet (PoE) with the introduction of ‘lite’ versions of two of its most popular Ethernet switches. The new versions of the PS14P and PES42H each offer four PoE enabled RJ45 10/100Mb copper ports, with the PES42H adding two extra ports which can be configured as copper or 100Mb fibre. The specifications are identical to their more expensive counterparts in every way, with the exception of a slightly less wide temperature specification, enabling these cost-effective networking products to be used in all but the most severe environmental conditions.

The PS14P and PES42H are designed to provide connectivity for clusters of Ethernet-enabled devices, meeting evolving network needs for increased flexibility. Compact, rugged, and hardened for harsh industrial environments, the switches provide an affordable means of connecting remote IP devices and instruments to the wider network.

In addition, by delivering Power over Ethernet, the switches provide a convenient means of extending network infrastructures without having to run separate power cables. The list of PoE enabled equipment coming to market is growing rapidly, and includes the likes of IP video surveillance cameras, wireless access systems, VOIP phones, badge readers, and many others.

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 RJ45 ports on the PES42H and PS14P 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.

Over and above the features common to both products, the PES42H also includes Link-Loss-Learn (LLL), enabling it to be used in self-healing and redundant LAN structures.
