IP 406 Burnt smell and rebooting

I installed a new IP Office 406 a few weeks ago. We reused old cable and had to tone existing station cables. I was toning a cable for number 2 of the analog station ports. I cross connected while the toner was still connected. I shortly thereafter noticed that the system had crashed and the 406 was rebooting and not starting. The leds on the 406 would flash but it wouldn't start. There was also a burning smell coming from the 406. I cleared the system, reloaded the firmware/software/database and the switch came back to life but the 2 analog station ports were dead.
I got a 406 overnighted and replaced it and all was well for 4 weeks.
I then got a call about the the number 1 analog station port of the 406 not having dial tone. I toned the cable and found a loose punch on the cross connect. I repunched the pair and walked to the station and unplugged the toner. I then heard complaints that the phones were dead. I looked at the 406 and the christmas tree effect had begun again. The 406 would not restart. Burnt smell again. I had a spare and quickly reinstalled it.
My question is "Has anyone else had this happen?". I use a Progressive toner. The only thing that was common to both occurances is the toner.
 
I have herd of analog toners causing digitl pbx;s to reboot. I would sugest you get a digitl toner .

I would sugest disconnectig the DS port before connecting the tone.
 
The chip that controls the analog ports is shot. If you were to open it, the two analog chips would burn your fingers (to the touch). We've actually ordered replacement chips and replaced them since they tend to be so touchy.

We've never had the issue caused by a toner, but rather a surge on the analog lines. Usually it happens for us on FAX machines, or Phones that are on a dock (with a metal roof).

Hope this helps...

I power down the module/s, or pull the patch cord when toning. The IPo seems to lock up ports with a traditional toner at times. I have never burned a port, but have needed to reboot, so I didn't tone a second one while hot since.

You do not always get what you pay for, but you never get what you do not pay for.
 
I've fried a new system with a toner. Same story as yours. Acutally could see the burnt chip in the ip office unit when I pulled the cover off.

I try not to use toners while lines are plugged in, but that can be difficult at times when you are trying to find a line in a system that is having issues.

We weren't shure if it was truely a toner issue or if it was just a early failure. We had tons of failures on a batch of systems from our distributors. One or two ports out of the units would be bad, etc.

We even got some units that were mis-labeled and were totally different units than the box and sticker on the bottom of the unit said they were.

I would guess its probably the toner, but don't have any ideas on why or how. They shouldn't be blowing up chips.
