How to automate the control of PoE power via Linksys SRW208MP: PoE
Power Consumption: ALIX 2c2 + one CM9 wifi card + Silver Telecom adaptor:¶
- PA1212 PoE adaptor by itself (no load): 1.4 Watts
- CPU 100%, one CM9 not running: 6.2W
- CPU idle, CM9 running (scanning): 5.3W
- CPU 100%, one CM9 scanning: 7.1W
Therefore it seems that the IEEE PoE standard 15.4W could easily supply this node, possibly with 2 CM9 cards.
