Hello All!

I’ve recently configured a new Power Shield Defender 650VA UPS on my home SME server and it is working well. I would, however, like to change the shutdown behavior of the server.

At the moment, when the UPS goes to battery, the server continues to operate until the UPS sends the “battery low” warning, at which point it auto-shuts down. I would like to change the configuration so that the server will shut down 2 minutes after receiving the “on battery” signal.

What is the best way to achieve this?

Thanks in advance.

P.S. For those Aussies who are thinking about getting one of these UPS’, I configured NUT to use the megatec_usb driver and set the port to “auto”.

HOWTO: Set Up NUT, the Network UPS Tools

Ted Felix

Note: This page is incomplete. I will remove this when I have successfully completed configuring my UPS with NUT.

The power goes out all the time here, so I decided to take a shot at setting up a UPS and having the server shutdown when the power goes out. This turned out to be pretty difficult as the “Network UPS Tools” are a bit of a pain to set up. Here are my notes so far…

UPS’s from Dell, MGE, and Eaton appear to be fully supported by NUT. Others should work, but if you can find one of those, it’s guaranteed to work.

The ubuntu package is “nut”:

$ sudo apt-get install nut

NUT is very painful to configure. Follow these steps carefully. The blasterspike.it link appears to be the best.

Identify UPS and Driver

Identify UPS. lsusb works for USB connected UPS’s. In my case, I have a “Cyber Power Systems CP1500AVR USB”.

$ lsusb
...
Bus 001 Device 003: ID 0764:0501 Cyber Power System, Inc. CP1500 AVR UPS

Check the NUT Hardware Compatibility List to figure out which driver will work for your UPS. For my USB UPS, the correct driver is “usbhid-ups”.

Update ups.conf and Test

Add a new section to /etc/nut/ups.conf for the ups. I picked “serverups” for the name. “ups” would probably be better for a simple setup like mine.

[serverups]
    driver = usbhid-ups
    port = auto
    desc = "Server UPS"

- Install udev rules for usbhid-ups (see man usbhid-ups INSTALLATION)
    sudo cp /lib/udev/rules.d/52-nut-usbups.rules /etc/udev/rules.d/
    reboot
- Set up /var/run/nut per
  http://www.blasterspike.it/2011/03/28/how-to-install-nut-on-ubuntu-10-10-maverick-meerkat/
    sudo mkdir /var/run/nut
    sudo chown root:nut /var/run/nut
    sudo chmod 770 /var/run/nut
- Test the ups.conf file:
    sudo upsdrvctl start
  Normal output:
    Network UPS Tools - UPS driver controller 2.6.3
    Network UPS Tools - Generic HID driver 0.35 (2.6.3)
    USB communication driver 0.31
    Using subdriver: CyberPower HID 0.3

upsd

- Launch upsd
    sudo upsd
  Normal output:
    Network UPS Tools upsd 2.6.3
    listening on 127.0.0.1 port 3493
    listening on ::1 port 3493
    Connected to UPS [serverups]: usbhid-ups-serverups
- Test the upsd with upsc
    sudo upsc serverups@localhost
  Should see values for a lot of variables.

More steps…

- Continue with the blasterspike.it steps.  They seem to be good.
  http://www.blasterspike.it/2011/03/28/how-to-install-nut-on-ubuntu-10-10-maverick-meerkat/
- upsd.users - Need to add a user id for upsmon to login.
- upsmon.conf - Need to add a line to monitor the ups.
- nut.conf - Set the mode.
- Start it up at boot.
  blasterspike uses the old "service" to start this.  Is upstart an option?
  It might be if we set it up ourselves.  As it stands, initctl does not
  appear to know of it.  See /etc/init.d/nut.

Five Minutes?

- Configure it to shutdown after 5 minutes instead of when the UPS goes
  critical.  I don't see a way to do this anywhere.  Strange.  What exactly
  is its criteria for shutting down?  10% battery left?  It's a UPS
  data item:
    battery.charge: 100  (percent)
    battery.charge.low: 10  (percent, this is when shutdown will occur)
    battery.charge.warning: 20  (percent)
    battery.runtime: 2887  (seconds)
    battery.runtime.low: 300  (seconds, this is when shutdown will occur)
  I think you can tweak this in one of the config files.  There's an
  override.  But this doesn't seem ideal.  There's no way to say that
  it should shutdown after 5 minutes (if it can last that long).

NUT Documentation

nut manual section 3.9 “One UPS, one computer. This is also known as “Standalone” configuration. This is the configuration that most users will use. You need at least a driver, upsd, and upsmon running.”

5.2 “Configuration files are located in /etc/nut. nut.conf(5) must be edited to be able to invoke /etc/init.d/nut”

Section 6 of the docs covers setup. Basically, the ups.conf file has to have an entry for the ups. Then it will work. (If only that were it!)

Config files for NUT: nut.conf(5), ups.conf(5), upsd.conf(5), upsd.users(5), upsmon.conf(5)

OpenUPSmart

Go NUT(s)!

12-12-2008

All units supported by OpenUPSmart should now be supported by the Network UPS Tools. If you are having issues with any of the UPS units previously supported by OpenUPSmart they will be happy to help.

OpenUPSmart should be considered retired; NUT is your best choice for robust UPS support.

About

OpenUPSmart is a UNIX based daemon mainly for the no name UPS available from Dick Smith Electronics in Australia. It is listed on the website simply as “UPS Power Supply UPS0400 400VA”, but otherwise has no unique identifying features. If you know anything more about this little UPS, please contact us!

Update: Thanks to the Google cache, this appears to be called the “Micro Master” UPS, originally made by a company called Centralion.

The Protocol

At first OpenUPSmart used data gleened from sniffing the serial line with the Windows software. On later investigation the protocol appears to be based on the Megatec protocol, available here. (thanks to Chris Barnesfor relating this to the sniffed commands). Although the particular UPS pictured and originally targetted does not appear to be able to handle all of the commands.

The Software

The software is aimed as a daemon based replacement for the Commander Pro software available from www.ups-software-download.com It appears to be authored by a company called Waytech.

If your UPS uses software from this site, you should be able to replace it with OpenUPSmart. Please report any success.

The Linux software available from that site in RPM format is called UPSmart (hence OpenUPSmart).

The goal of OpenUPSmart is to communicate with the UPS, poll it periodically for status updates and run commands on event changes (power failure, power restore, etc).

The software is targetted at building and running on Linux and NetBSD but should be portable to any UNIX style operating system.

The SourceForge project page is available here.

I got a scenario, where a software works only when you insert the USB device provided by the software vendor in windows operating system. Im trying to find the content stored in the USB device. In windows operating system, the USB device icon is not shown in My_Computer. I thought, I can see the content or atleast detect the USB device in Ubuntu.Also in ubuntu, the drive is not detected. I tried “sudo fdisk -l” to know the file system, but its not useful. The drive is not detected at all.I wanted to know, how the software works only when the USB drive is inserted and it wont when it is not inserted. Do they have any files stored in the USB device? In any case, how can we detect such kind of device in Ubuntu?

Hi all, I am trying to get apcupsd going. I have installed it thru synaptic, set it up accordingly to the various guides one can find across the net. When I run “acpaccess” I get the following error. “Error contacting apcupsd @ localhost:3551: Connection refused” What, if anything, can I do to rectify the above situtation. I am on Ubuntu Lucid 10.04.2 Desktop. Thanks.
