WOW, thanks for the quick responses guys.

Just an update on the situation. I found out that my assistant inadvertantly put the ELD in slot 1 and the MPD in slot 3. When he turned on the system he said he heard a sizzle :-(.

So the MPD is in slot 1 and the ELD is in slot 3. I have taken a phone into the back room and hooked it up directly to the punch down block, but still get nothing on the phones at all. I thought that I would at least get something on the LCD screen.

I know that you guys aren't able to actually see the system, but in your best estimation do think that the boards have been fried? If so where can I get an MPD and and ELD (also need 4 more phones) to replace them.

To get them going I just installed 4 single line phones and bypassed the system entirely so that they could at least make and receive calls.

Thanks again so much for the help. Will check back in an hour or so.
