I have a UX5000 9.5 64 Port 2.50 CPU.System appears to be working fine with Intra Mail There is a solid light on LED 2 .I know they refer to it as an alarm light but how do you clear it
I also tried to upgrade the software to 3.5 and it did not work (never had this happen before) I had to down grade it back to 2.5 in order for it to work again
I tried several different software versions but none of them worked
I just upgraded another account a while back and it worked fine

I think it has something to do with the LED 2

anyone have any suggestions

Memory card needed for 3.52?

LED 2 is an alarm light. You can't clear it from Web Pro - the easiest way is to clear it from the phone programming interface. You go to menu 90-53-01 to clear it.

You will also find that the alarm LED on NEC systems is kind of a joke. Half of the time, the alarm is on and you can't figure out what is causing it - nor can the NEC Tech support.

So, as long as the system is running okay - I would say don't worrry about it. The software upgrade should work for you - if you are using a USB stick - it might be a compatibility issue.

Thanks for the response 90-53-01 worked fine
As far as the upgrade from 2.5 to 3.5
I just did this a while back for a customer & it was fine
(It was prior to installing a new intra mail -for some
Reason it did not like the data base that was on this system
I loaded another data base & it did upgrade to 3.5
However I had other issues with the LAN port
Could not conect I could ping it but it would not conect
Then I just defaulted it ( it's just a bench system that I aquired
It was definitely a learning experience
I will definitely think twice prior to upgrading
A UX seeing that it's discontinued
