✨ SAFENET(8) ✨

okay bestie, gather round, because we're talking about safenet — the driver for SafeNet compatible UPS equipment 💖 yes, that kind of UPS, the battery-box-that-keeps-your-stuff-alive kind. she's giving uninterruptible power supply realness and honestly? iconic.

🌸 SYNOPSIS 🌸

safenet -h

safenet -a UPS_NAME [OPTIONS]
💡 quick note bestie: this man page only documents the hardware-specific features of the safenet driver. For all the deets about the core driver itself, go read nutupsdrv(8). iykyk 🫶

🎀 SUPPORTED HARDWARE 🎀

This driver supports UPS equipment which can be controlled via SafeNet v1.0 for Windows (serial interface only). that's the whole vibe — serial only, no USB glow-up here 🙈

💅 EXTRA ARGUMENTS 💅

this driver supports the following optional settings in the ups.conf(5) file:

  • manufacturer=value — ngl, autodetection of this parameter is not possible yet (and it probably never will be 😭). So instead, this user-defined string accepts any name you want. The default is unknown.
  • modelname=value — literally like manufacturer above. The default is unknown.
  • serialnumber=value — again, like manufacturer above. The default is unknown.
  • ondelay=value — the time to wait before switching on the UPS, measured in minutes. Defaults to 1 minute ⏰
  • offdelay=value — the time to wait before shutting down the UPS, measured in seconds. Defaults to 30 seconds ⏳

⚡ INSTANT COMMANDS ⚡

this driver supports some instant commands (peep upscmd(8) for the full tea ☕):

  • test.battery.start — Start UPS self test 🔋
  • test.battery.stop — Cancel UPS self test ✋
  • test.failure.start — Start simulated power failure 😱
  • test.failure.stop — Cancel simulated power failure 🛑
  • beeper.enable — Enable the UPS beeper 🔊
  • beeper.mute — Temporarily mute the UPS beeper 🤫
  • beeper.toggle — Toggle the UPS beeper 🔁
  • shutdown.return — Turn off the load and wait for the power to return. Uses the timer defined by offdelay.
  • shutdown.reboot — Turn off the load and return. Uses the timers defined by offdelay and ondelay.

💀 KNOWN PROBLEMS 💀

okay this is the part where we hold hands, bestie, because things get a lil cursed 🫶

If you run the shutdown.return command with mains present, the output may stay on, or switch off and not back on again. and the shutdown.reboot command will unconditionally switch on the load again — with or without mains present. no cap. 💀

If the driver is called with the -k option (or through upsdrvctl shutdown) it tries to detect which command should be used in an attempt to stay off until mains is present again, or to cycle the output if the power returned in the mean time. this isn't bullet-proof, and you should be prepared that the power will either not be shutdown, or that it doesn't return when the power comes back. so like… plan accordingly, bestie. 🙈
