We always lay bare facts about certain basic considerations when installing devices. One such area we like making a great observation is whether the device should be PoE or just plain when it comes to choosing Ethernet Ports.

There obvious advantages for choosing PoE route though it might cost a little bit more

For network designers and administrators, PoE simplifies the task of powering devices in remote locations. In one key example, PoE changes the entire cost structure for deployment of VOIP phones in an enterprise, where phones need to be placed in locations without dependency on AC outlets.

The primary benefits include:

Cost savings – PoE significantly reduces the need for electricians to install conduit, electrical wiring, and outlets throughout the enterprise. With PoE only one cable – a simple CAT-5 Ethernet – is required.

Flexibility – A PoE appliance or device can be located anywhere without the need for AC outlets. For example, wireless LAN access points can be located – and relocated – on or near ceilings, to fine tune optimum RF reception. For example, customers often find that access points are more effective on the ceiling, out of reach from an AC outlet.

Reliability – Because PoE networks have fewer wires, there is less likelihood of an inadvertent power disruption (accidental shut off, etc). With an Uninterrupted Power Supply (UPS) power to the devices is assured during a power failure.

Network Control – Using SNMP, network administrators can monitor and control powered devices, including resetting or shut-off. This allows increased security, as devices can be powered down when not in use, or if there is unauthorized access.

Safety – Power mains are eliminated. Since only 48v DC is used, PoE conforms to Underwriter’s Laboratories (UL) Safety Extra Low Voltage (SELV) classification.

These benefits provide significant bottom line business impact.
