IEEE 802.3at (Draft 4.1)-Compliant Single-Port PD-9501G
Midspan Supports Gigabit Switching While Delivering 15
Percent Better System Efficiency Than Alternatives
Microsemi Corporation (Nasdaq:MSCC), a leading manufacturer of high performance analog/mixed signal integrated circuits and high reliability semiconductors, today announced the availability of the world's first 60W, single-port Power-over-Ethernet (PoE) midspan with gigabit switching support, highly efficient four-pair operation, and full compliance with the IEEE 802.3at draft 4.1 high-power PoE specifications. Microsemi's PowerDsine(tm) PD-9501G may be used with a wide range of advanced PoE Powered Devices (PDs) including 802.11n Access Points, WiMAX CPE and base stations, Pan-Tilt-Zoom cameras and thin clients that require high power and support of 2-event classification as specified in the latest IEEE 802.3at specifications.
"With Microsemi's PowerDsine PD-9501G, we continue to deliver on the promise of the emerging 802.3at standard, enabling our customers to get the best possible functionality out of Power over Ethernet," said Sani Ronen, senior product line manager for Microsemi PowerDsine Midspans. "This new Midspan offers a combination of high power, gigabit support and 2-event classification. It is a pioneering solution in a PoE market where, until today, the barrier to PoE adoption was its restriction to 15.4W and 30W, respectively, in 802.3af and 802.3at applications. ThePD-9501G will enable a host of new Ethernet applications to take full advantage of the well-known PoE benefits at 60W power levels."
KEY FEATURES
- 802.3at draft 4.1 compliant, delivers up to 60W on 4-pairs
- 2-event classification
- 10/100/100 BaseT support
- Unique interlock mechanism
A key feature of the PD-9501G is its ability to deliver power over all four pairs of Ethernet cable, which dramatically improves performance and efficiency as compared to two-pair products. Four-pair powering enables the PD-9501G to maintain a low, 600mA current level while delivering 60W of power. This contrasts with alternative 2-pair midspans that must feed 60W with current levels of 1.2A. As a result, the more efficient PD-9501G makes 51W available for PD consumption using a CAT5 cable, as compared to 42W for 2-pair solutions.
In addition to its 60W operating mode, the PD-9501G may also be used to power 2-pair devices with up to 30W. In this case, the midspan still uses all four pairs of CAT5-and-above cable, which enables it to dissipate up to 50 percent less power on the cable. A PoE system using the PD-9501G will consume almost 15 percent less energy than a conventional 2-pair solution, which translates into savings of approximately $25 per year per powered device, assuming energy costs of $0.10 per kilowatt hour (KWH).
The PD-9501G midspan unit also includes a unique interlocking feature that allows users to scale their deployments by incrementally linking together multiple one-port midspan units as new PDs are added to the network. The new midspan also enables Microsemi customers to develop powered network devices with the advanced functionality enabled by the IEEE 802.3at specification.
PoE midspans offer the IT manager a simple, economic means to deploy Power over Ethernet appliances such as VoIP phones, WLAN access points and IP cameras, without replacing the IT infrastructure. The PD-9501G complements Microsemi's portfolio of midspan products, including managed and unmanaged products in a wide range of densities from single- to 48-port configurations.
Pricing and Availability
The PD-9501G midspan is available in production for a unit list price of $119. Product specification and application whitepapers are available. Additional information is available at Microsemi's website: http://www.microsemi.com.
