col) UPS equipment
NOTE
This man page only documents the hardware-specific fea-
tures of the fentonups driver. For information about the
core driver, see nutupsdrv(8).
SUPPORTED HARDWAREfentonups primarily supports Fenton Technologies models
such as the PowerPal, PowerPure and PowerOn lines. Due to
the common heritage of UPS equipment, it generally sup-
ports other hardware that also uses the Megatec protocol.
At the time of this writing, the PowerGuard PG-600 and
PowerCom SMK-800A are recognized and supported. Other
Megatec units should also work, but they will generate a
warning since their battery information is not known.
EXTRA ARGUMENTS
This driver does not support any extra settings in the
ups.conf(5).
BUGS
The battery percentage is derived from the voltage data
that the UPS returns, since the UPS doesn't return that
value directly. On some hardware, the charge will remain
at 100% for a long time and then drops quickly shortly
before the battery runs out. You can confirm from the
BATTVOLT readings that this is a problem with the UPS and
not this driver.
Similarly, the float from the charger in some models
forces the battery charge percentage back up to 100% imme-
dately after the UPS goes back on-line, so you can't tell
when it is really recharged.
Dead/broken batteries can't be reported reliably. If your
UPS kills the load instantly or within seconds of starting
the inverter, your batteries probably need to be replaced.
Recently, a pair of 3.5 hour outages here (thanks CPS!)
finally killed my batteries. You may have to run a manual
test from the front panel before the "replace battery" LED
will light.
