[cisco-voip] Network printer from behind a phone?

I would be more concerned about the fact of the printer losing connectivity when you reset the phone and/or do code upgrades.

If the printer puts unsupported voltage on enet pairs it's going to fry switches as well as phones.  Otherwise, if the printer emits enough emag it might affect the phone.  In that case use a longer cable and move the printer further from the phone.

Perhaps there's a possibility of upstream electrical damage, but don't know if there would be any more risk than a PC. Printers do have pretty big power draws so perhaps there is.

Is there any reason we couldn’t (or shouldn’t) hang a network printer off of the PC port of a 7960?  The documentation is a little vague … only stating “other devices”.

Thanks.
