PoE devices from Microsemi are claimed to reduce energy consumption on network cables by as much as 50% compared to alternative midspans and PoE network switches. The PowerDsine PD-5524G EEPoE midspan complies with IEEE802.3at 2009 standards for delivering up to 30W to network devices including IP cameras, access control systems and thin clients, over the same standard CAT5 cabling as data. The 24-port midspan halves the Ethernet cable energy dissipation, which equates to 240kWh in annual energy savings assuming continuous operation across 12 ports at full power. Additional energy savings are possible using the midspan's PowerView Pro secure remote power management, which enables network administrators to monitor and control power devices and their power consumption outside business hours, on holidays and weekends. The PowerView Pro scheduler restricts power delivery to five 12-hour weekday cycles for additional savings. The midspan is the first to leverage a distributed power architecture, which enables smaller internal power supplies to be used for real-time requirements. These can be added to with the company's PowerDsine RPS 450 or other external switching power supplies. The midspan supports 10/100/1000BaseT data rates and complies with IEEE802.3at to support high-power devices such as PTZ cameras, WLAN access points and thin clients.
