About this device

CyberPower OR500LCDRM1U - Inexpensive 1U rack mount UPS

This UPS has the same ondelay/offdelay issue that other Cyberpower UPS’s have, the UPS expects minutes for those values, and rounds down. So the default values of 20 and 30 get rounded down so the UPS shuts off immediately.

The ondelay for this model doesn’t work very well.

  • If you give it a value of 60 seconds, the UPS will power back on the load after 60 seconds even if the mains power isn’t back.

  • An ondelay=-1 disables the auto start behavior.

  • Setting an ondelay value of 0 seems to be the only useful value. With ondelay=0 the UPS will start back up immediately if the power is restored after the UPS shuts down, and it will restart the load approximately 10 seconds after a shutdown if the power comes back after the shutdown with delay command is sent.

I would suggest that if the default values are changed for cyberpower models, that the ondelay be set to a default of 0, and the offdelay be set to 60.

I’ve successfully tested the shutdown behavior with this UPS with a FreeBSD system (pfSense firewall). The offdelay must be set greater than 60 and the ondelay must be set to 0 for correct behavior. (FreeBSD doesn’t remount into a RO mode during shutdown, so delayed shutdown is absolutely needed to prevent disk corruption).

One last note is that this system doesn’t seem to have any nonvolatile storage, any values set via upsrw are lost when the UPS is restarted. So if you want to tweak certain settings you will need to have a way to reset them any time the UPS resets.
