Hi Dean,

Well I thought I did when I was swapping cards previously. But, just in case
I just went and and removed the station cards and inserted them one at a time
into slot 1 and then powered up. Same thing. NO SYNC

What seems odd is that when I power up with no station cards or even with no
cards at all installed the same thing is displayed on the the phone.

It would seem that the mother board is not seeing the cards at all.
But, I am really not sure if that is normal or not.

Needless to say when I installed the system 14 years ago all worked as it should and has been
flawlessly since then. Which is like anything that works till it don't!!

Any additional thoughts would be nice.

Thanks,

Les

The STSe KSU (3501-00 or -01) has a well-known power supply issue that causes this exact scenario. On the older 3500-00 or -01, the memory battery was the problem like clockwork and wasn't too difficult to accommodate in the field with a soldering iron. Not so with the STSe. Because the power supply components are part of the motherboard itself, it's not an easy fix, especially in the field. Your best bet is to send it in for repair to SoTel, Vertical's authorized factory service center in CT. Of course, you'll need to buy or have a replacement KSU while waiting for the repair turnaround. At least you'll get it back with all of the most current updates and ECOs.

Thanks Ed.

My customer now has a new NEC SL2100 system installed and working quite well.
They were down for about 5 days with a 2 line business phone in order to answer
customer calls. This STSe is presently in my storage shed. I was hoping or considering
that if it was a rather easy fix, such as a battery, I would swap out the DHS system in my
office that has been working for a whole lot longer than this STSe. It would seem that
will not be the case.

Again, thanks for the input and have a good week!!

The power supply has a certain capacitor that historically goes bad with age, it was time for an upgrade.

Just to throw in my 2 cents... After you replaced the battery, did you reprogram the slots to recognize the cards? If not, the phones/ lines attached will not function and will display the "no sync" thing, because it is in default mode. Maybe I overlooked this in the post somewhere, but not sure.

Hi adteldon,

The simple answer is "no" I did not. Actually do not know how to do that function.

So would you mind (re)educating me on what is needed to be done in order to give it a try??

Thanks!!

Flash 24 is where you assign cards to the slots. Flex key 4 represents the first station card slot, 5 for the second station card slot, flex key 6 for the first CO line card slot, etc. Press the key that represents the appropriate slot, then enter 02 for a digital station card + hold. Be sure to reboot the system using flash 80, button 20 for this change to take effect.

Hi Ed,

I do appreciate the assist. However, I am a bit mystified. If I power up with Ext.100 connected to the system
and I have the display showing the model and version info for the phone data and NO SYNC being displayed
and pressing any key does not change anything, how to I get in to programming??

Honesty, I don't have it powered up at the moment but when I did a couple of weeks ago I pressed some keys
and nothing happened on the display. Maybe I hit the wrong keys, I don't know. From what I was seeing the
display was just a dumb display and nothing more. Should have taken a picture at the time, but didn't.

Anyhow, given the parameters is there someway to maneuver through the Flex or Flash Keys as you describe
from Ext. 100 that will break the "NO SYNC"?? Or possibly, as I suspect I am beating a dead horse??

Thanks,

Les

Les, you can try initializing the system while it is powered up by switching DIP switch #8 to the on position, pressing the reset button, waiting for the system to start and then switching #8 back off. The system might come up then, but honestly, it will only last until the next power outage.

Hi Ed,

I already tried something like that?? But, I may have did it out of sequence.
I will give it another shot.

Are you saying that even with a fresh battery the initializing will only hold for
one power cycle??

Thanks,

Les
