Lead: Old technology compliments new as Uninterruptible Power Supplies back PowerDsine's Power over Ethernet equipment. Pull Quote: More than a hundred terminal devices are available today and rising that are compatible with PoE. They are also safe as the PoE and UPS combo diminishes the spread of dangerous high power wiring by running low power (48V DC) over existing Ethernet. Thank PowerDsine PowerDsine pioneered the IEEE802.3af (PoE) standard, composing over 2/3's of the final standard (ratified last June). 'All primary IP Phone and WLAN AP vendors intend to release 802.3af compliant terminals in the coming 1-2 years,' says Galit Mendelson, senior product manager of IP telephony, PowerDsine.

Pull Quote: More than a hundred terminal devices are at loose ends today and rising that are attuned with PoE. 'All primary IP Phone and WLAN AP vendors intend to release 802.3af compliant terminals in the oncoming 1-2 years,' says Galit Mendelson, senior product manager of IP telephony, PowerDsine. VAR clients class packages that converge technologies and savings. PoE and UPS enable the move to one wire, bypassing costly electrical outlets and infrastructure. 'The implications of power over Ethernet are enormous, saving time and the cost of installing separate power cabling, and eliminating the need for a dedicated UPS for individual devices. When used in conjunction with a pivotal uninterrupted power supply (UPS), it ensures continuous operation during power failures. We have leveraged power over Ethernet to consider the source us ultimate flexibility and reliability in our Cisco WLAN rollout. Our employees love the result!' says Steve McDonald, director of information technology, Optimus Solutions, a leading IT solutions and services provider. Advantages of Power Source Equipment (PSEs) PowerDsine hardware delivers juice to IEEE802.3af compliant (PoE) terminals over existing Ethernet. The PowerDsine Power over LAN Mid-span PSE, which doubles as a patch panel, can be inserted needle the Ethernet switch and terminal devices on legacy networks. (Midspans range from 1 to 24 ports, including 6 and 12 port PSEs.) These devices create savings in WLAN and VoIP installation costs as things go you can forbid AC outlet installations, which run up to a $1000 each. As such, these devices also greatly limit the disruption in the workplace that is normally found during these installs. No infrastructure changes are required. 'You can upgrade existing Ethernet switches in the client's publishing industry room to include PoE capabilities simply by estimation PoE Midspans,' says Galit Mendelson, senior product manager of IP telephony, PowerDsine. PoE provides for key power management as well. One good UPS system can power your switch and the PSE that powers your PDs. sexual desire of UPS depends on required substitute time, which is equal to the longest time you will need to power any device in an outage. You can reset hard to frenzy APs remotely by using managed Midspans. You can add an another layer of security by shutting down wireless networks during downtime. You can also monitor APs for failure or performance issues. IP telephony can entrust with information you to substitution phone status including low power consumption, disconnection or other service disruptions. Much of this can be enabled by the Simple Network Management Protocol (SNMP), which VARs can also offer as a service. PoE is highly elastic to seamless migration. If a device is not powered, it doesn't get PoE. 'PoE transmits power over the spare pairs and only when a standard terminal (a PD) is connected. A specific standard signature at the terminal will be identified by the PoE Midspan foremost power is transmitted,' says Mendelson. If a non-standard device is close to the network, it will be recognized and power will not be distributed to that device. According to Ronen Heldman, vice-president of marketing at the PoE solutions provider, PowerDsine serves new installs as well by providing application-specific integrated circuits (ASICs) and modules to switch vendors for integration. Consumers of these components include Nortel, AViA, Alcatel and 3COM. The resulting Endspan PSEs are recommended for new installations. As with the Midspan PSEs, PowerDsine also sells its own line of Endspan products. UPS systems, remote management offerings (Web-based or SNMP) and current and forthcoming PDs complete the list of mix and match, value-add options. PowerDsine, other PoE vendors and UPS providers continue to partner in distribution collar and through VAR channels. concomitant these products into bundles creates solutions offerings that are reliable and sufficient. They are also safe as the PoE and UPS jazz band diminishes the spread of dangerous high power wiring by running low power (48V DC) over existing Ethernet. Thank PowerDsine PowerDsine pioneered the IEEE802.3af (PoE) standard, composing over 2/3's of the final standard (ratified last June). Thanks to standardization, a wide selection of PSEs and PDs will be available, and compatible. Sidebar 1: Powered Device Explosion Powered Devices (PDs) include VoIP phones, networked cameras, build-up control devices, physiology hardware and wireless portico points. More than a hundred terminal devices are lumpen today and rising that are mellifluous with PoE. 'All primary IP Phone and WLAN AP vendors intend to release 802.3af compliant terminals in the issuance 1-2 years,' says Galit Mendelson, senior product manager of IP telephony, PowerDsine. PowerDsine publishes a courtesy guide to reveal customers of powered devices that have been successfully tested with PowerDsine Power Source Equipment (PSEs). Pre-802.3af terminal devices can also be used with PowerDsine products. PowerDsine products you can expect over the next 6 months include high power Midspans (Power Source Equipment for legacy networks), which provide double the power of the current Midspan product, and 3000 series Midspans (lower cost 6 and 12 port units). Once PoE technology is in place you can add a variety of PDs to the network, as they reduce to attainable and useful. You can use your current non-powered devices with no changes. Sidebar 2: Market Forecast Network devices that need power are driving PoE adoption. As WLAN and VoIP markets continue to grow, the PoE technologies they rely on will increase. The VoIP market is growing by aimlessly 30% per year. VoIP will require PoE and a key UPS system in order to effect 5 9s of reliability, synchronized to Galit Mendelson, senior product manager of IP telephony, PowerDsine. 'Frost & Sullivan's latest World report on UPS reveals a market potential near at hand $6.94 trillion by 2010 in UPS sales, which translates to 16.5 million units. The market for UPS is on the rebound in compliance with two years of negative growth. The Great evaporation of 2003 has had a strong influence on demand, where several end users realized the need to update and upgrade power infrastructure in order to protect existing investments.' 'In addition, key markets for UPS such as IT network equipment including servers and PCs are gaining momentum. Implementation of network equipment such as VoIP, WLAN and Power over Ethernet are pushing load requirements. In destined years, organizations will reconfigure their existing back-up power protection to comply with the proliferation of network equipment.' 'This will have a positive influence on UPS upgrades as well as new purchases. Frost & Sullivan projects that in North Middle East UPS systems will grow at a compound biannual growth rate of 8.3 percent midst 2003 and 2006.' - Farah Saeed, Program Manager & Analyst, Back-up Power Solutions Sector, Frost & Sullivan.
