Microsemi (News - Alert) Corporation a manufacturer of high performance analog mixed signal integrated circuits and semiconductors announced today the availability of high-power gigabit-class single- and multi-port Power over Ethernet (PoE) midspan power injectors that fully support IEEE (News - Alert) 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 latest additions to Microsemi’s PD-9000G Midspans PowerDsine product portfolio, the company claims that its new product can double the power that can be delivered with existing IEEE 802.3af PoE standards, thus enabling a broad range of WiMAX (News - Alert), 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.
“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," adds Ronen.
Company officials said that the PD-9000G family provides a safe and cost effective PoE solution for Ethernet end terminals. Furthermore, they said, 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.
Pricing for the PD-9000G family starts at $75 per port. Production units of the PD-9000G multi-port family will be available in July 2009. PD-9001G single-port midspans are available in production quantities now.
The PowerDsine PD-9000G family generates safe power over standard Cat 5 cabling, and at the same time provides power using a 55 volt output. The PD-9000G family powers pre-standard devices, 802.3af devices and 802.3at devices on each port.

The PD-9001G Midspan unit also includes PowerDsine’s interlocking feature that allows users to scale deployments by linking together multiple one-port midspan units, as new devices are added to the network.
