upsrw output:

[driver.debug]
Current debug verbosity level of the driver program
Type: NUMBER
Value: 0

[driver.flag.allow_killpower]
Safety flip-switch to allow the driver daemon to send UPS shutdown
command (accessible via driver.killpower)
Type: NUMBER
Value: 0


upsrw -l output:

Instant commands supported on UPS [ups]:

driver.killpower - Tell the driver daemon to initiate UPS shutdown;
should be unlocked with driver.flag.allow_killpower option or variable
setting
driver.reload - Reload running driver configuration from the file
system (only works for changes in some options)
driver.reload-or-error - Reload running driver configuration from the
file system (only works for changes in some options); return an error
if something changed and could not be applied live (so the caller can
restart it with new options)
driver.reload-or-exit - Reload running driver configuration from the
file system (only works for changes in some options); exit the running
driver if something changed and could not be applied live (so service
management framework can restart it with new options)


usbhid arguments:

desc = "Emerson Network Power Liebert GXT4"
productid = 0000
ignorelb
override.battery.charge.warning = 40
override.battery.charge.low = 30
default.input.voltage.nominal = 120
default.input.voltage = 120
default.battery.voltage.nominal = 48
default.battery.voltage = 54

UPS shutdown has been tested.

I suspect these same parameters will also work for other GXT4 models and
the GXT3 family as well, since they seem to share the same controller.

Can anyone test a GXT5?
