PES42P power source edge switch combines standard 802.3af Power over Ethernet (Po)E 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-enabed devices, and combines this with fibre 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 fibre ports, or one fibre 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.
The PES42P is suitable for use in a broad spread of industrial applications. It is NEBS L3 and ETSI compliant for vibration, shock and altitude, and carries UL, cUL and CE approvals. Emissions meet FCC Part 15, Class A standards. For use in power utility substations, the PES42P is certified to IEEE 1613 and IEC 61850 standards. The PES42P is rated for ambient temperatures from –40°C to +75°C, and is hardened for outdoor use and for use in challenging environments. On request, it can be supplied conformally coated for addition protection against moisture, humidity and chemical attack.
Mixed media devices such as the PES42P which combine the copper connectivity typical of Ethernet-enabled cameras with fibre connectivity offer effective solutions for traffic control and monitoring applications. GarrettCom pioneered mixed-media modular Ethernet products in 1993, and was the first company to offer the convenience of PoE ports integrated in industrial-grade switches – both managed and unmanaged. |
