When does software maintenance start on a Tridium license (JACE, WebSup or portability controller)?

Software maintenance starts when the software license is purchased.

Is software maintenance and warranty the same thing?

No.
Software maintenance enables access and updates to the latest Niagara build. For example, updating the software from N4.9 > N41.0.
Warranty covers the JACE8000 from manufacturing defects.

Does a Niagara license (JACE / WebSup) automatically include maintenance at the time of purchase?

Yes, it includes a minimum of 18 months from the date of the license activation. There are initial purchase options for 18 months, 3 years & 5 years of SMA.

Can I buy more than 1 year of software maintenance at a time?

Yes.
SMA can be purchased for 1, 3 or 5 year periods.

How will multiple quantities of maintenance appear on a license?

Dates will run consecutively (i.e. buy 2x 1 Year SMA = 2 years of SMA).
Software maintenance dates will show in the license header details and in license view.

What if I choose not to renew my Niagara 4 maintenance?

If the SMA has expired on the Tridium license, it will continue to run the station. However, the JACE / WebSup will not have access to any new versions, update builds or patched releases for Niagara 4.

Gap charges will apply if you choose to renew once the SMA has expired. This means if your maintenance expires, and you miss 12 months of SMA you would need to purchase a 3 year SMA license. The ‘missed’ maintenance period of 12 months would be used straight away, leaving 2 years of active SMA.
