The IEEE 802.3af standard for delivering Power over Ethernet Allows for up to 15.4 Watts per port. For 24 ports, that equates To 370 total Watts. Competitive products typically provide 200 to 250 Watts total output power. Even so called "HIGH POWER" units with non-standard maximum output power of 39 Watts only offer a total of 200 Watts.

If the application is 24 wireless access points, each drawing 14 Watts per port, no other 3af midspan can provide enough power to ALL the devices. There are a few options to meet the requirement. Install multiple 6 or 12 port Units, which consumes valuable rack space, and are much more expensive per port. Install a limited number of units per injector (a 200 Watt unit would only power 14 WAPs), or the increased cost of a high power standard injector. The only viable solution is SEI's Midspan MX.

The Midspan MX is designed to provide FULL POWER To all 24 ports. With its total of 382 output watts available, the MX powers 24 devices, each drawing 15.4 Watts. The MX has enough power left over to charge the optional BACKUP JUICE; an integrated UPS System specifically designed for the MX.
