I have been hot swapping cards since I first touched a Toshiba system several years ago. So far only issue has been a voicemail rebooting when the card next to it is installed. Since I was curious, I looked through the Installation manual:
"Toshiba recommends turning the power supply be Off whenever possible when removing or
installing the other PCBs"

The line before that one:
"WARNING! The power supply must be Off whenever removing or installing the
processor PCBs."

Seems to me like thay are saying that you can hot swap, but power down if possible.

You MUST power off to swap out CPU and voicemail cards, that has just been common sense.

Generally, it has been common knowledge that you can hot swap CO and station cards as what would you do in a 4 or 5 cabinet system with a couple hundred people out there? No one would buy a Toshiba if you had to always shut it down.

Is is always nice to power down but pushing the 3 white buttons has on a couple RARE occasions has been necessary.

If a BSTU did not work in place of a RSTU, then all five RSTU cards are probably not bad but it would still be rational to give that a shot.

My most educated guess would be that you have a problem CPU, either in S/W or hardware.

I don't know if you are with a dealer or not, but at this point, I would capitulate and have Toshiba modem into it and examine software.

You could spend two more weeks on this and get to that point. I don't know if you have external gel cell batteries hooked to this, but I always try to put battery backup on all Toshiba systems and as large as a 1200 is, it simply would have been reflected in the cost of the proposal as a necessary item with the battery distribution gizmo. They SAVE ies16 and 32 voicemails, I know because a cheap customer talked me into not putting in the batter backup and I paid $600 to fix the ies32 when the building power went out.

When transformers are replaced, etc. A HUGE but short spike comes in and fries anything it can.

I put in surge supressors from a company in Utah called EFI that clamp 2500 volts at 2500 amps in 1/1,000,000,000 of a second and high retail would be $100.

My best guess is that you got a spike and it killed part of the CPU. Thats a good guess, not a diagnosis.

Ok, thanks.
I always power down my system before anything concerning CPU handling.

Now, I'll call my Toshiba dealer as soon as possible. i.e. as soon as the the budget is approved. (I have no contract support with this dealer so I have to make sure of everything before any budget approval).

For the record:
- yes my system is on batteries (probably due for maintenance, but still working good).
- I don't see any good surge suppressor.
- My voicemail system is Esnatech 7.1. (BTW, does anyone know a good support forum for Esna system?)

Thanks all, again your help is appreciated.

ESNA is a Canadian company so there should be many available vendors for it around you, it is also the same as a Perfect Voice voicemail and Teleco sells and services them still I believe.

Also another step you may try is to swap power supplies on the Single line cabinets with another non single line cabinet to see if this might help. I had one system in the past that did the same thing and we ended up swapping the poewer supplies, single line cards AND the cabinets they were in due to back plane issues.

i guess it depends on the power factor in a particular cabinet but i have seen it happen right in front of me as i was telling them not to do it. also watched it happen on a DK16.

update:
- I erased all the lines on the RSTU card,
- unassigned / reassigned the card,
- reprogrammed all the lines.
The SLT lines are now ringing.

I work on my other phone system issues with a Toshiba tech since a week now.

We suspect a corrupted DB.
