Microsemi debuts new family of high-power PoE Midspans

Units feature high-efficiency powering scheme, mutual backup


IRVINE, Calif., May 18, 2009 -- Microsemi Corporation, a leading manufacturer of high performance analog mixed signal integrated circuits and high reliability semiconductors, announced today the industry's first high-power gigabit-class single- and multi-port Power over Ethernet (PoE) midspan power injectors that fully support IEEE 802.3at-draft4.1 specifications while delivering previously unavailable system efficiency features, backup capabilities and smart network power management.

"The PD-9000G family changes the Power-over-Ethernet field, by bringing full IEEE802.3at-draft4.1 compatibility together with the same award-winning management capabilities found in the PowerDsine product line," said Sani Ronen, product marketing manager for PowerDsine Systems at Microsemi. "The PD-9000G flexible powering options -- from AC, DC or another midspan -- make it perfect for every type of IT deployment. Plus, the PD-9000G family is an ideal choice for mission-critical verticals such as healthcare and finance, where network administrators can take advantage of the family’s remote-management capabilities -- including being able to shut down ports at certain times of the day -- along with the family’s ability to be integrated with UPS systems so that low-priority ports can be disconnected during power failures."

Microsemi’s PD-9000G Midspans are the latest additions to the company’s PowerDsine product portfolio. They double the power that can be delivered with existing IEEE 802.3af PoE standards, thus enabling a broad range of WiMAX, PTZ and dome network cameras, 802.11n access point and thin client network applications. The PD-9000G family is available in 1-, 6-, 12- and 24- port versions in a 1U format, and a virtual 48-port 2U midspan.
 

Further improving power efficiency, the PD-9000G Midspans include PowerDsine's exclusive PowerView Pro™ management option, now supporting both IPv4 and IPv6 addressing, which allows simple and efficient monitoring and control of network devices. This secure SNMPv3 application enables remote power-off/power-on, unit scheduling, UPS power monitoring and web-based monitoring. IPv6 is critical for building PoE infrastructure built to last for the next decade, and is a must-have feature by governments worldwide. Additionally, the PD-9000G family introduces the unique feature of allowing interconnected midspans to back each other up in case of a power supply failure. The PD-9000G DC inputs can also be used with external power supplies, which can be used to increase the power capacity of a midspan or provide redundancy.

The PD-9024G full-power unit is the sole 1U solution in the market that is able to provide full power of 30W in 802.3at mode for all 24 ports simultaneously. Additionally, the PD-9000 series offers a unique high-power mode that supports up to 36W per port and a total of 864W in 1U mode for the PD-9024G full-power unit.

The PD-9000G family provides a safe and cost effective PoE solution for Ethernet end terminals. More devices can be powered via the network, thus eliminating the need to use a power supply and install costly power outlets close to the end device. In addition, by using the PD-9000G series now -- which powers on the spare pairs as required by the current PoE standard -- a network will be ready for 4-pair powering by combining with another PoE switch.

The gigabit interface makes the PD-9000G family an ideal solution for gigabit video phones, WiMAX transmitters or 802.11n access points. Its high efficiency design achieves low temperatures inside the midspan enabling improved reliability.
