Display voltage

Anonymous user · ‎2021-06-29

I have a APC model SYHF6KT that will not display input or output voltage it is blank after those's two headings on the home screen and no manual to reference

I have looked at the diagnostic screen and it is showing no faults or errors

This being a Symmetra RM, it sounds like the powerview has lost comm with the intelligence modules or there is an SYCC card issue....

I'd first try unplugging the powerview display to see if it comes back after doing a reset - pull the uppermost plastic cover (that has the powerview built into it off the front of the UPS (it will be attached by the powerview's cord) , momentarily unplug the powerview's comm cable from the Main Intelligence module, leaving it unplugged for at least 10 seconds, then plug it back in again. Its hot swappable so there should be no risk of ups crash.

If that doesn't work you could try pulling the SYCC symetra communications card from the rear of the UPS chassis , wait 10 to 15 seconds then plug the card back in. I believe this card controls communications for the whole UPS frame...Again, its hot swappable.

Thank you for the reply !The ups is not in bypass mode and seems to be functioning fine .I have an IT guy asking why the unit is displaying this on the home screen, is this normal?

None of the LED's are lit on the front of the unit and someone has turned on the maintenance bypass switch
