PoE MidspansExtend Enterprise Infrastructure with Ease

As the enterprise network expands, so do its operational benefits. Previously, the ability to extend networks locally was limited by proximity to a power source. Historically, extension meant adding a network-capable device, connecting it via ethernet, and supplying the device with power. If power wasn’t extended, neither could the network. Now, Power over Ethernet (PoE) allows data and power to transmit over a single cable, enabling enterprises to quickly deploy network devices at locations farther from central power sources.

The origins of PoE began as enterprises sought solutions that would allow the installation and use of devices in locations where power was difficult to supply. The Institute of Electrical and Electronics Engineers (IEEE) approved the first PoE standard, supporting up to 15.4 watts of power, in 2003. Since its initial development, the PoE standard has continued to advance, allowing progressively higher levels of power transmission and enabling further benefits to the enterprise.

Using PoESeveral factors should be taken into account when choosing a PoE solution. For example, any future plans for expansion of the network that the PoE device will be connected to should be considered. PoE-enabled switches, known as endspans, and PoE hubs, commonly referred to as midspans, are two equipment types that can act as power sources and a maximum of 15.4 watts per port (link) can be sent over the local area network (LAN) cabling system to the powered device.

Power delivered over the LAN infrastructure is activated automatically when a compatible powered device is identified. Power is blocked automatically to any legacy devices that are not PoE compatible. Users can safely mix legacy and PoE-compatible devices on a network.

PoE AdvantagesCost - No need for electricians to install electrical wiring and related materials.

Flexibility - Devices can be located wherever a network cable can reach them.

Safety - PoE protocols protect network equipment from electrical malfunctions.

Reliability - A central, controllable source provides primary and backup power.

Scalability - Where the network goes so can network-extending devices.

PoE midspans allow businesses to reap tremendous advantages. In addition to reduced costs, organizations receive key benefits including time, flexibility, and ease of extending network infrastructure.
