Since 802.3af power-over-Ethernet is not sufficient for many new 802.11n APs (assuming at least 2 antennas and RF chains at 5 GHz, a dual-radio AP will draw at least 15W*), 802.3at PoE is needed to support 802.11n installations *Some AP offer 802.3af powering option but usually with reduced functionality 802.11n 802.3at © 2011 Microsemi Corporation.

PowerView Pro Power Management Device Prioritization No service contract IPv6 Compliant Remote Reboot Web-based SNMP tool Monitoring Device Scheduling – Improve power consumption and network security by scheduling devices off during periods of planned non-use Device Prioritization – allows you to improve utilization of UPS in case of external AC power failure. Devices can be priortized to power down based on remaining power Available with all G and High Power devices. No service contract. Cost built into device purchase price. Device Scheduling

Power Savings with Scheduling Enterprise/Campus WLAN Working hours: 7:00 - 20:00 Monday to Friday AP Consumption: 12.5W (load agnostic) Yearly power consumption no scheduling: 12.5W x 24 hours x 365 days = 110 KWh Yearly power consumption w/scheduling: 12.5W x 13 hours x 250 days = 41 KWh Savings: 138KWh/year €0.1/KWh* = €7.9/year per WLAN AP * Source: Europe’s Energy Portal Business case example: 240 AP’s = €1,656/year savings ROI in 1/year Midspan life-cycle: 10-years (lifetime-warranty) Midspan return: 9x€1,656 = €14,904
