The latest security and surveillance cameras, digital signs, and wireless access points rely on Power over Ethernet (PoE) as a convenient method for communicating with a network while receiving power at the same time. PoE technology passes electrical power and data over the same CAT 5 Ethernet cable eliminating the need for a separate power line. The PoE standard per IEEE 802.3at provides up to 15.4 watts of DC power to each device. The newer PoE+ or PoE plus standard serves up 25.5 watts. PoE allows long cable runs up to 330 feet (100 meters).
Layer 2 Manage Features
Managed PoE switches include standard Layer 2 functions like VLAN, QoS, IGMP, rapid spanning tree, redundancy, and security. They also include power management features enabling network administrators to remotely access a wide range of capabilities to configure, manage, and monitor the network.
A PoE ping alarm command turns on or off any PoE port. Cycling power to a PD (powered device) in this manner resets or reboots a device. Or, you may program the switch to power recycle a particular PoE port at regular intervals. For energy savings, a scheduler in the web console interface allows you to appoint any date and time to enable or disable a PoE port. For example, you could turn off PoE lighting during the daytime hours. A simple unmanaged PoE switch cannot perform these types of functions.
Westward Sales offers a full line of industrial-grade managed PoE switches that boast a variety of port-counts, mounting, and power options. Choose from Fast Ethernet and Gigabit Ethernet speeds with or without fiber-optic ports. Most PoE switches accept 48 volts of power input. However, our low-power versions (-24 part number suffix) will operate with the 24 VDC power sources found in industrial control cabinets. And, they may be powered from 12-volt batteries. These versions are a great choice for solar-powered systems.
Select the Right Gear for your Network
Like all of our networking equipment, our managed PoE switches are built to withstand the toughest conditions. Outdoor panels and dirty factory floors are no match for these devices.
