Following the ratification of the IEEE802.3at standard for Power-over-Ethernet applications up to 25.5W, Phihong continues to offer its range of .at-compliant midspans.

Providing up to 30W per port and full compliance with the final power specifications, Phihong’s PoE Plus midspans are available in single-, four-, eight- and 16-port models.

Applications that will benefit from the increased IEEE802.3at power levels include: IEEE802.11N wireless multi-radio points, Pan Tilt Zoom security cameras with heaters, and IP phones with streaming video displays.

The POE36U-1AT is a single-port midspan designed to power wireless and Wimax access points that require up to 26W of power, and is also suitable for IP telephones with streaming video and high-quality Pan Tilt Zoom Cameras with heaters for outside locations.

The POE125U-4AT is a four-port midspan that provides 33.6W to power four wireless access points or security cameras.

It also supports Cisco AP1250 Series products in full-power mode and other high-bandwidth access points in full-power mode.

The POE576U is a low-cost 33.6W-per-port midspan that provides eight or 16 ports at full power for 10/100/1000 Base-T networks and requires no power management.

This Power-over-Ethernet device, available in eight- or 16-port versions, is ideal for powering VoIP phones, biometrics and access for security systems, IP cameras and wireless access points.

The POE576U-24AFAT is a 24-port midspan that provides eight IEEE 802.3at ports with 33.6W per port and 16 IEEE 802.3af ports with 15.4W per port in a single 1U chassis.

Providing a solution for sites where a variety of power levels are required, this ‘hybrid’ midspan is available with SNMP network management support, as well as an external redundant power supply for five nines reliability.

The midspans provide diagnostic LEDs and are Gigabit-compatible.

All products in the high-power midspan line have safety and protection systems designed to meet the IEEE 802.3 standards, including detection, disconnect and overload control.

Over-temperature protection allows the midspans to automatically shut down without being damaged and the outputs are equipped with short-circuit protection.

Also, in case of over-voltage, the outputs will shut down without any permanent damage to the midspan.

Beyond the .at standard, Phihong has developed a Power-over-Ethernet midspan product line that offers the highest power-per-port available on the market.

Currently available in two- and four-port versions, the POE240U-2MP and POE576U-4MP Gigabit-compatible Mega PoE midspans provide up to 95W of power per port, making them suitable for high-power applications such as computer workstations, LCD-display panels and wireless access points.
