[Asterisk-Users] Asterisk & POE

Hi Guys,

This one may be slightly off topic, but we are planning to do an 
asterisk installation that uses POE to supply phones with power.

Not being overly familiar with the POE standard, I'm not sure if this 
will cause regular network cards etc that may be plugged into a POE 
switch to end up being fried.

A quick squizz around seems to tell me that the IEEE standard 802.3af 
incorporates some form of "auto sensing" Algorithm that allows the 
switch to detect if it should supply power to a particular device.

Can someone confirm for me if I can have VOIP phones using POE and 
regular network cards plugged into the same switch ?

Any help would be appreciated.

Cheers,

Callum
