A PoE Midspan is not a switch. A Midspan is an additional PoE power source that can be used to offer full power to all endpoint devices. PoE Midspans (Power Hub or Power Injector) pass data from a switch and ‘inject’ safe power acting as a patch panel of sorts. Midspans are commonly used with either a non-PoE switch, an existing PoE switch, or a new PoE switch in a network. In addition to offering full power across all available ports, midspans costs substantially less per port and overall than a new PoE enabled switch.
Midspans do not switch – they make use of existing best-in-class switches. They inject safe power across all ports and cost less than PoE switches. .
