[Asterisk-Users] [OT] PoE (Power over Ethernet) for 7940G

[Michael Welter]

I have a few 7940G phones on a LAN hub, and I'm looking at the 3COM 
3CNJPSE power injector.  Can I put one of these behind my LAN hub and 
power all the phones, or do I need one for each phone?

From the spec, it looks like PoE tries to discover whether a device is 
powered over ethernet.  Can I just put 48VDC on pins 7-8?  Will my 
Netgear pass this through to the phones?

Thanks,
