Hello,

Just got a Nortel m3904 business phone off Ebay. However, for the life of me, I can not find the power supply input on the phone. All I see are plug-ins for a 2-line 8pin and 2-line 4pin plug.

I'm assuming that is the power supply. Where can I get a power supply for this phone?

Thanks in advance.

There is no Pwr supply needed for operation. It is line powered.
Hope this helps!

I am hoping that you know this, but you do realize that the M3904 is a system telephone right? You cannot plug this into a household jack. It will, at best, not function at all and, at worst, if it gets hit with household ring voltage it will be fried out.

the m3904 is made for the M1 switches. They will only work with the opt11 mini. 11c, 61c or 81c release 23 or higher.
