SMT1000+AP9630 USP log: "time" field values

[BillP]

Hi there!

I have an SMT1000 (fw 09.3 ID18) equipped with NMC2 AP9630 (fw 6.4.0), and all works fine!

Just here to ask about the meaning of "time" field on "UPS Logs" page on NMC web interface.
It should be in millisecond? (millisecond from the absolute first powering up when came from factory?) or what?
It's normal that is converted in dd.mm.yyyy format? (of course 2002/2000 are not plausible values)
p.s: I already formatted/reflashed the nmc card and "reset to factory" the ups.
Thanks!

Hi Luca,

I can tell you that the 'ms' in the Time column needs to be removed and that will be completed in the next version of Smart-UPS firmware for AP9630/31/35 NMCs. We used to provide it in ms but recently tried to make it look nicer and more understandable to the user so there should be a time/date there which is what you're seeing - except that it is wrong.

One of my colleagues is checking into this as I am thinking it could be an NMC or UPS firmware issue. We'll try to confirm that and let you know the next steps or if there is a solution.

I know the time ultimately is coming from the UPS but either the time from the UPS is wrong or the NMC is converting it incorrectly for you.

Hi Luca,

At this time, the problem appears to be on the UPS firmware side from our investigation. Long story short, we'll have to report the potential bug to the UPS firmware team and have them review it. Assuming there really is a bug, then they'd hopefully fix it in a future UPS firmware version for your SMT1000.

Thanks Angela for your interesting.
How to set/adjust the UPS internal clock? (using frontal panel?)
I thought that UPS takes clock info from NMC real time clock when it's installed, isn't so?
My NMC clock is currently synced using a NTP server (GPS, straum 1) every 60min.

I noticed another thing: new events (i.e. UPS automatic periodic test, or a manual UPS test started by frontal panel) seems to be logged in NMC log list but not in UPS log.

Hi Luca,

I am not certain on all the details of the process but I think that the NMC sets the time somehow on the UPS, at least for this function. The time on the UPS itself cannot be set by the user as far as I know - they can only set the time on the NMC, if installed, or PowerChute software if they're using that. So, maybe there is a problem with how the UPS is receiving the setting from the NMC or something like that. An NMC firmware engineer checked and was able to identify the NMC firmware was doing what it needed to properly.

I also think that the UPS log only shows last 10 fault conditions or last 10 transfer reasons. The NMC log or PowerChute logs are much more detailed and those are the logs I'd usually refer to rather than the UPS logs. Typically, if you're UPS is having a very specific problem would tech support as for the UPS fault logs versus the standard NMC log.
