PowerDsine Limited
PowerDsine Ltd., (NASDAQ:PDSN) designs, develops and supplies integrated circuits, modules and systems that enable the implementation of Power over Ethernet in local area networks, providing the capability to deliver and manage electrical power over data network cables. PowerDsine offers integrated products and system (midspan) solutions to communications equipment manufacturers in the telecom and datacom industries who incorporate them into, or bundle them with their products. These products enable PoE capabilities to their Ethernet switches or networks in order to deliver PoE for applications such as voice over IP (VoIP) phones, wireless LAN access points, and IP security cameras. PowerDsine is a founding, contributing and active member of the IEEE 802.3af and 802.3at Task Forces.
PowerDsine Integrated PoE Solutions
PowerDsine offers innovative silicon solutions for PoE (Power-over-Ethernet) applications. The chips & modules (total PoE solutions on standard DIMMs) integrate power, analog and advanced digital logic functions into a single device. It is optimized for use in Ethernet switches, routers and midspans, allowing next generation network devices to share power and data over the same cable.
PowerDsine's solutions are designed to answer a broad range of needs – from the high-end Enterprise all the way to SOHO, SME and residential applications. Industrial switches are also a main target, as IC temperature range applies to industrial environments.
Implemented using Freescale's SMARTMOS8™ technology, PowerDsine solutions allow the detection of IEEE 802.3af - compliant terminals (powered devices or PDs), ensuring safe power feeding over Ethernet ports. With full digital control via a serial communication interface and a minimum of external components, the ICs can integrate into any switch, router or gateway.

PowerDsine PoE Midspan - Lower total cost of ownership
PowerDsine's PoE Midspan offers significant financial benefits when compared to upgrading existing Ethernet switches or replacing them with new, PoE-compliant switches.
- Low purchase cost - Installing a PowerDsine's PoE Midspan costs less than upgrading to new PoE switches, since Midspans can easily connect with existing Ethernet switches. Sunk costs are maintained (i.e. current switches) and the expense is incurred only for the PoE Midspan, as opposed to purchase of brand new PoE switches (that would be purchased most likely only for the PoE support).
- Low installation costs - Midspan is a plug & play product making the installation much easier than a PoE switch. There is no need any software downloads.
- No downtime - PowerDsine's PoE Midspans enable higher productivity due to the fact that their addition to the network involves negligible downtime (typically a few hours in a single day of work).
- Easy & simple installation – Only an IT Engineer is needed to install PowerDsine's PoE Midspans (as opposed to the massive network engineering efforts required to upgrade or install new PoE switches). The Midspans also require less support and maintenance.
- Minimal learning curve - New PoE Midspans implementation is an easy adjustment for IT personnel. Quick system stabilization prevents a decrease in business productivity. Installation of new PoE switches necessitates education of IT personnel regarding new configurations, troubleshooting, maintenance, upgrades, which can be time-consuming.
- Interoperable with most network devices - PowerDsine's PoE Midspans are interoperable with all Ethernet switches and most terminals. They are compliant with the IEEE 802.3af PoE standard as well as Cisco Inline power. PoE Midspans can be used in conjunction with different switch vendors, and end-terminals which not comply with the PoE 802.3af standard.
- Secure PoE management - PowerDsine's Midspans include secure SNMP V3 power management modules and enable remote Web-based management, as well as other advanced and flexible power management features.
- Future cost proofing and scalable implementation - When the time comes to consider Ethernet switch replacement due to new technologies or standards in the switch market, (e.g. as security 802.1x with Guest VLAN, or, 802.1x with Port Security), it will not be necessary to pay again for PoE functionality.

Microsemi Announces First Pre-standard IEEE802.3at Power-over-Ethernet Integrated Solution
Switch manufacturers waiting for a 802.3at solution can now can use the high power PoE Plus ICs for Microsemi (PowerDsine). As the new standard gets ever closer more manufacturers can be ready for the expected rush to take up the technology.
Designated the 3001G, this newest member of the PowerDsine 3000 midspan family eliminates the need for external power supplies at remotely deployed Wireless LAN access points and other low-density networks having 10/100/1000 Base-T Ethernet-connected devices. It is fully compliant with the IEEE 802.3af PoE standard and can provide remote power to either 802.3af-compliant or pre-standard devices.
Designated the 3500 Series, the new midspan family is designed to deliver safe power over standard Ethernet cabling to existing 10/100Mbps network devices, such as VoIP phones, WLAN access points and IP network video cameras in enterprise installations. Two versions are offered: the Model 3524 midspan which provides 24 ports, and the Model 3512 with 12 ports.
Microsemi Corporation has announced that the HiPath(r) Wireless 802.11n and Outdoor Access Points from Siemens Communications, Inc. are the first on the market to be certified at Microsemi Corporation's PowerDsine(r) testing facility for applications requiring high power, yet at the low power ratings specified in existing standards for Power over Ethernet (PoE).
