| 3 | 5 | laforge | @laforge bought two Livingston Portmaster 3 PM3A-1E, which are RAS (Remote Access Server) that |

| 5 | * provides ISDN dial-up on those channels |
||
| 6 | * provides DSP based modems in case analog modem calls should be handled. |

| 20 | The original fan is aFonsan DFB0812M (DC 12V 0.1A) fan by DELTA ELECTRONICS INC. The specs seem to state 2600 RPM / 24.8 dB(A) / 29 cfm. |
||
| 21 | |||
| 22 | I found it too noisy and replaced it with a Noctua NF-A8 FLX with L.N.A (reduced to 1650 rpm / 12.9 dB(A) / 24 cfm) |
||
| 23 | |||
| 24 | Fun fact: The PM3 actually seems to have a 5V -> 12V DC/DC upconverter just for the fan - instead of simply using a 5V fan... |
