So I finally sprung for the VoIP kit for an NEC and as I was upgrading my CPU to 3.20 and adding the board, the system refused to come up. It goes through the boot sequence, then it starts over. When I plug in a digital phone, it comes up for about 5 seconds and the boot process starts over. Wow. I don't know if Mr. Static got it, or the VoIP daughterboard, or it just plain died. Anyway, I ordered a new CPU, just in case it's something simple.

Has anyone ever seen anything like it? The power supply still has the 3 green LED's. And, it's my office spare demo kit, but it's over 2 years old

what does NEC tech service have to say about it ?

I would have been talking to them before ordering in new parts

I would try a different CF card when you upgrade the switch.

I should have thought of that, Skip. I called Teledynamics TS, but forgot about calling NEC's.

Since my order won't be here until Wednesday, I'll touch base with them on Tuesday. I have a 30-day restock option without penalty on the CPU.

@STS I used the CF on the 40 and it worked fine. It's only loaded with 3.20 and nothing else, not even a back up of the 40.

Carl, check your firmware if the cpu is that old.

And remove the VM CF and try restarting the unit.

NEC would of told you this but Ive never had the problem myself.

You are running a ver 3.0 or above in the system you are attempting to upgrade ?

No, I went in both the DSX-40 and the DSX-80 from 2.25 to 3.20. It's just a download to CF and boot the system from there. The 40 worked, the 80..not so well. Since I did 2 things at once, I can't tell whether I did something or it just is my bad luck. The 80 has been on my warehouse shelf lightly used for over 2 years. I just sold a 40 this month and decided to test remote maintenance, upgrade the box, and add VoIP.

I suppose I could degrade the system back to 2.25 and start over, but I'll trust NEC to advise and I can always fall back on the CPU changeout for testing. It may be that the digital card is bad, but it's tough to tell. It still seems to cycle with just the CPU and nothing else, so it seems to be CPU or power supply..because that's all that's left.

usually nothing but a bad CF card.
Some just won't work.

As Brokeda stated,if you take your system back to Ver. 2 series different procedures with up/down
grade.

Carl, go to the DSX site and read these procedures
if you have not all ready done so.

That may get you a better picture what is going on.

I think you will be able to bring life back to the 80.

It's impossible to brick the DSX. The boot ROM will always provide the capability to load software from the CF card.
