Why choose PoE?
It’s simple. PoE uses standard CAT 3 or CAT 5 Ethernet cables, so in terms of installation, it’s really no different than setting up a regular network. The only specialized equipment needed is a PoE-compliant switch.
It’s really convenient having multiple power devices over a single network. This eliminates the need for separate power and data cables, which makes for seamless installation and easy maintenance.
Furthermore, having a centralized power supply for all of the power sourcing equipment eliminates the call for each powered device to have its own ac/dc convertor or uninterruptible power supply.
It offers great flexibility. PoE can be installed anywhere, which means power devices can be placed wherever they’re needed, whether or not they’re near an existing power source. And since they don’t need to be located near an ac outlet, devices (and even entire systems) can be moved and adapted to suit any changing need of an application.
Unbeatable savings! There are two ways that you’ll save with PoE: network installation and energy management. We already covered the installation part, which saves on materials, labor and installation time, but PoE offers even greater savings through its effective energy management capabilities. That’s because most PoE switches support simple network management protocol (SNMP), which gives the administrator the ability to monitor and manage power consumption from a remote location.
Being able to so easily control your network’s power efficiency allows you to decide if and when to put a device (or system) into low-power or sleep mode (e.g. during off-peak hours like nights and weekends).
Terrific reliability. PoE allows for centralized power back-up solutions which, in turn, helps ensure constant availability of powered devices. When every power sourcing equipment is combined with this capability, the network is fully optimized for continuous operation, all but eliminating any chance of power interruptions and downtime. What’s more, the combination of the aforementioned SNMP and control logic allows the administrator to troubleshoot, restart, shut down and/or put measurement equipment into a safe state if ever the need should arise.
