| 3 | 6 | Rodney Berriman | The low cost node consists of an ALIX 2c2 or similar board from PCEngines http://pcengines.ch/order1.php?c=4, together with a Power-over-ethernet adaptor that can extract the 48V supply from PoE and convert it to 12V to power the board. |

| 5 | 6 | Rodney Berriman | Suitable adaptors are: |

| 7 | 7 | Rodney Berriman | * Silver Telecom PA1212 (tested at NICTA) |
| 8 | 7 | Rodney Berriman | * Linksys DLW-P50 http://www.dlink.com.au/products/?pid=368 (tested at NICTA) |
| 9 | 7 | Rodney Berriman | * Linksys WAPPOE12 - http://www.voiplink.com/Linksys_WAPPOE12_p/linksys-wappoe12.htm (NOT tested at NICTA) |

| 15 | 3 | Rodney Berriman | h3. Power Consumption: ALIX 2c2 + one CM9 wifi card + Silver Telecom adaptor: |
| 16 | 3 | Rodney Berriman | |
| 17 | 3 | Rodney Berriman | * PA1212 PoE adaptor by itself (no load): 1.4 Watts |
| 18 | 3 | Rodney Berriman | * CPU 100%, one CM9 not running: 6.2W |
| 19 | 3 | Rodney Berriman | * CPU idle, CM9 running (scanning): 5.3W |
| 20 | 3 | Rodney Berriman | * CPU 100%, one CM9 scanning: 7.1W |
| 21 | 5 | Rodney Berriman | |
| 22 | 5 | Rodney Berriman | Therefore it seems that the IEEE PoE standard 15.4W could easily supply this node, possibly with 2 CM9 cards. |
