MICS-where is time/date stored?s/ware or backplane?

[DComm1]

I have a customer who has a 4.1 mics that loses time.
auto day light has been changed to NO.
Is the time/date stored on the s/ware cartridge?pcm card?
Back-plane?
The system is about 4 years old.
Not sure what needs to be changed out.....

its stored on the software cartridge, do they have a stable power source i normally find that older switches suffer with that after power cuts

Remember if it doesn't work hit it harder

Does the system come with a battery, I don't recall, some ofthe old NEC did and cause that same problem

 

[phones1]

the batery for the software is in the cartridge, if you take it apart you could replace it but fot the cost you might as well replace the s/ware cartridge

Remember if it doesn't work hit it harder

4.1 has been out for about 6 years
I dont know if it is on the cabinet or the NVRAM

when you say it loses time - does it slow down even when working continually without power interruption. - this is known
If it loses power, then the clock stops.

In the PBXs there is an option to automatically adjust clock (example like 10 seconds in a day)
