| 5 | 1 | laforge | The hardware consists of two circuit boards: |
| 6 | |||
| 7 | * Top board: AC/DC power supply and Ethernet switch |
||
| 8 | * Bottom board: Actual Femtocell mainboard |
||
| 9 | |||
| 10 | The two boards are sandwiched together by the following connections: |
||
| 11 | * 6-pin fine-pitch connector (most likely for DC power) |
||
| 12 | * flexible printed circuit cable (most likely for Ethernet MII/RMII) |
||
| 13 | * two large sheet metal parts for ground and/or thermal connection |
||
| 14 | |||
| 15 | It is thus not very straight forward to operate the opened device in a safe way (i.e. without live AC line voltage present). |
||
| 16 | |||
| 17 | We will be working on a way to operate it with injected safe low DC voltage, but that is still TBD. |
