WinSPM PC causes Magix to reset 1

[TouchToneTommy]

I think someone had this problem, but I can't find it in the archives.

Customer has a Magix R4, 1-412TDL, 1-024TDL, 1-016TR, 1-800LSGS, MMsr R4, and 100D

A PC connected to the Admin port for SPM, always connected, but only accessed SPM once or twice a month.

When the user shuts this PC down for the day, it causes the Magix to reboot.

Year old building, all Cat-5, using a patch cord from Admin port to the patch panel, and a patch cord to the 355-A to a 25 to 9 adapter to the serial port. Nothing weird there.

Any thoughts; Bad processor? No modem in the PC, or I would simply switch them to a internal modem setup.

TTT, Can you test it with a DIRECT Rj-45, doing away with the patch panel?

That may prove something.

Also, is this WINSPM-9?

It is SO FLAKEY!

 

[TouchToneTommy]

Yup, it's WinSPM 9, but it's not even running when she shuts down her PC.

I will try a different cable run, and maybe even string a fresh cat-5 down the hall to test.

I thought someone else had the same problem, wondered if there ever was a resolution.




BTW, I worked with an SC who used a 4-conductor RJ-11 line cord to connect from the Admin port to the 355, and it always worked for him!!

Since you have an available 016 module - perhaps with an open slot - why not just switch to using the PC's modem to connect via WinSPM, instead of the admin port/serial port to connect - unless you really want to spend a lot of time trying to figure this out. Maybe it is the PC, the PC serial port, the cabling, the processor admin port, a bad 355 AF adapter - who knows - it take weeks to tease out the real cause.

Ahh - I just noticed that she has NO modem in her PC - maybe it's time to get one. They cost a lot less than the time you are going to have to spend to try to figure this out.

Hi TTT, could you be referring to thread 689-1172295?

Thanks Alex. That's the one I was recalling.

Looks like there was never a resolution there either.

My error log has the same "DUART failure", and that's a chip in a serial port, so I'm guessing that the problem is the processor.

I'll try resetting the Admin port, but since it's past warranty, they may just want to disconnect when not needed.

This may have no bearing, but I had a customer long ago that was having problems with their PC freezing up or the Admin port either fried or not responding. Turns out the PC and the Legend were not sharing the same A/C outlet and there was an electrical difference in the two feeds. Had to replace the processor and the motherboard in the PC several times before the engineers had us verify that both the PC and the phone system were plugged into the same outlet. They attributed the problems we were having to variable ground potential between the two outlets. After that we always got in the habit of testing A/C voltage for correct polarity, voltage between hot and neutral, hot and ground. Finally no >1.0 volts A/C between neutral and ground. Not sure if this pertains to your case.

TTT, I'd be willing to bet COMDATA is RIGHT ON with this AC issue.

 

[TouchToneTommy]

I think you're onto something! Of course, the PC is located some distance from the switch, hence the connection through the Cat-5 cabling. I'll have to get out the VOM and see if we can find anything.

 

[comdata]

The only reason I mention this, from my understanding of what was told to me was, that if both PC and Phone System do not share the same A/C outlet, but are connected to each other thru RS232 protocol, any floating ground or voltage will put a spike onto one of the pins of the RS232 cable and blowout or freeze up the Admin port and/or the motherboard or both.
One last thing on testing the A/C outlet; we were always told to measure the ohms between neutral and ground as well. It should read < 1 ohm ideally. Also, they must not share the same as a Laser printer. Good luck!

 

[Pepperz]

My bet is the Processor modem. They sometimes are just goofed, sometimes won't talk to certain other modems. You MAY have luck going through a TR port, but my bet is the processor. If hte wiring is a year old, then the processor must still be under warranty.

This is why the Installation manual makes such a big deal about proper BONDING and GROUNDING of the system and being in compliance with the NEC!!

This can also turn into a safety issue....

if its any help, i had this problem before and it was a TrippLite rj45 surge protector that was causing the problem. everytime you rebooted the PC with it in, it would make the Sytem reboot.

TTT
Is the serial port on the PC on the motherboard or is it on a PCI or ISA board? When the PC is shutdown is it a logoff or complete powerdown?
I have seen a case something like this where the PC processor during shutdown/powerdown sent something strange to the serial port during the closing process which caused the device it was connected to to go nuts. In this case it was a MB port, adding a separate serial board corrected the issue. Food for thought.
