Hello! First post, please be gentle!
I have some APC UPS devices that I'm trying to log in to. They are currently configured to use telnet -- as a safety precaution, they can only be accessed from our 'bounce' machine. Because I want to do this from a script on my local machine, I'm doing it... (2 Replies)

5. What is on Your Mind?
This thread reminded me of a couple of screwups made by an operator in my old job. The ops used to run OS backups through a script which asked for the path to the tape (/dev/rmt/whatnot). We (the sysadmins) would give these to the ops if a new server was added or the h/w path changed. One Sunday... (4 Replies)

POWERPANEL(8) NUT Manual POWERPANEL(8)
NAME
powerpanel - Driver for PowerPanel Plus compatible UPS equipment
NOTE
This man page only documents the hardware-specific features of the powerpanel driver. For information about the core driver, see
nutupsdrv(8).
SUPPORTED HARDWARE
This driver supports CyberPower BC1200, PR2200 and many other similar devices, both for the text and binary protocols. The driver will
autodetect which protocol is used.
EXTRA ARGUMENTS
This driver supports the following optional settings in ups.conf(5):
protocol=[text,binary]
Override the default autodetection of the protocol.
manufacturer=value
If you don't like the autodetected value, you can override this by setting it here.
model=value
Like manufacturer above.
serial=value
Like manufacturer above.
ondelay=value
Time to wait before switching on the UPS (1 - 9999 minutes, 0=indefinite). Only available with the text protocol driver (see Support
Status).
offdelay=value
Time to wait before shutting down the UPS (6 - 600 seconds). Values below 60 seconds will be truncated to 6 seconds intervals, values
above 60 seconds to 60 seconds intervals. Only available with the text protocol driver (see Support Status).
VARIABLES
Depending on the type of your UPS unit, some of the following variables may be changed with upsrw(8). If the driver can't read a variable
from the UPS, it will not be made available.
input.transfer.high
writable: high transfer voltage point in V
input.transfer.low
writable: low transfer voltage point in V
battery.charge.low
writable: remaining battery charge percentage for low battery warning
output.voltage.nominal
writable: nominal output voltage in V
ups.start.battery
writable: allow cold start from battery
COMMANDS
Depending on the type of your UPS unit, some of the following commands may be available.
o test.battery.start.quick, test.battery.stop
o beeper.enable, beeper.disable, beeper.toggle
o shutdown.return, shutdown.reboot, shutdown.stayoff
On many devices, these commands are unreliable, so before using them you must verify that these work as expected (see Shutdown Issues).
o shutdown.stop
SUPPORT STATUS
Vendor support is absent for this driver, so if you need some features that are currently not available, provide ample documentation on
what the driver should sent to the UPS in order to make this work. If more information would be available on the binary protocol, it would
probably be possible to make ondelay and offdelay configurable. So far, nobody has taken the time to investigate what we should tell the
UPS to make this work, and CyberPower isn't willing to share this with us.
SHUTDOWN ISSUES
If the shutdown.return command on your UPS doesn't seem to work, chances are that your UPS is an older model. Try a couple of different
settings for offdelay. If no value in the range 6..600 works, your UPS likely doesn't support this. In order to get the expected behaviour,
it requires shutdown.stayoff (when on battery) and shutdown.reboot (when on mains). The driver will automatically fallback to these
commands if shutdown.return fails, and tries to detect which one should be used when called with the -k option (or through upsdrvctl
shutdown).
This isn't bullet-proof, however, and you should be prepared that the power will either not be shutdown or that it doesn't return when the
power comes back. All models supported by the binary protocol and many supported through the text protocol are affected by this.
KNOWN PROBLEMS
The CyberPower OP series don't offer direct voltage, charge, frequency and temperature readings. Instead, they will return a binary value
that needs conversion to the actual value.
The exact conversion needed is unknown at the time of this writing, hence an estimation was made based om readings from actual devices.
This may (probably will) be off, possibly a lot. Unless you can tell us the exact mapping between values from the UPS and actual readings,
don't bother to complain. We've done the best we can based on the limited information available. Remember, a UPS isn't a measuring
instrument.
