PoE Midspans Boost Efficiency

Supporting 10/100/1000 Base-T rates, the 24-port PD-5524G EEPoE Power-over-Ethernet (PoE) midspans promise to reduce network-cable energy consumption by about 50% over similar midspans and PoE switches. It complies with IEEE802.3at 2009 for delivering 30W to network devices over CAT5 cabling and relies on PowerView Pro secure remote power management software, which allows power-consumption control after hours, holidays, and weekends. PowerView Pro scheduler can restrict power delivery to five 12-hour weekday cycles. List price for the PD-5524G EEPoE is $1,799. MICROSEMI CORP., Irvine, CA. (800) 713-4113.
