  • Now have got Network UPS Tools (NUT) working for UPS in the ctalab
    • This will shutdown the server automatically in the event of a power outage, and notify me, Bill, and Massimo
  • Brief summary of what was done:
    • Mostly followed directions from here: https://kinavu.org/install-and-configure-nut-on-ubuntu/
      • sudo apt install nut
      • Add to files in /etc/nut/
        • ups.conf
          • [nevis-ctalab-ups]
            driver = snmp-ups
            port = nevis-ctalab-ups.nevis.columbia.edu
            community = public
            mibs=apcc
        • upsd.users
          • [monups]
            password = acdc
            upsmon master
        • upsmon.conf
        • nut.conf (this addition was done later in the process, may have been the cause of failures [previously MODE=none])
          • MODE=standalone
      • Created file /home/bin/notify.sh and made it executable
      • did sudo cp /lib/udev/rules.d/62-nut-usbups.rules /etc/udev/rules.d/ and followed it with a reboot
      • /var/run/nut already existed, so did:
        • sudo chown root:nut /var/run/nut
        • sudo chmod 770 /var/run/nut
        • Not sure if either of these were necessary
      • [TESTING COMMANDS] The upsdrvctl stuff that was being used in the tutorial was having issues, so I just tried out what Bill shared which was:
        • sudo systemctl enable nut-server
          sudo systemctl enable nut-monitor
          sudo systemctl start nut-server
          sudo systemctl start nut-monitor
        • and then: sudo upsc nevis-ctalab-ups to see if it was working
      • The first time I ran the testing commands, there wasn't a whole lot of output, except with the start nut-monitor I got out:
        • Job for nut-monitor.service failed because the service did not take the steps required by its unit configuration.
          See "systemctl status nut-monitor.service" and "journalctl -xe" for details.
      • So I ran systemctl status nut-monitor.service and it told me:
        • o nut-monitor.service - Network UPS Tools - power device monitor and shutdown controller
          Loaded: loaded (/lib/systemd/system/nut-monitor.service; enabled; vendor preset: enabled)

          Dec 29 16:12:07 ctalab-Precision-3630-Tower upsmon[2734]: upsmon disabled, please adjust the configuration to your needs
          Dec 29 16:12:07 ctalab-Precision-3630-Tower upsmon[2734]: Then set MODE to a suitable value in /etc/nut/nut.conf to enable it

          Dec 29 16:12:07 ctalab-Precision-3630-Tower systemd[1]: Failed to start Network UPS Tools - power device monitor and shutdown controller.
      • Following this, I:
        • Installed the server with sudo apt install nut-snmp
        • Changed in the nut.conf file: MODE=none -> MODE=standalone
        • Rebooted again
      • This seemed to work, full output:
        • (base) ctalab@ctalab-Precision-3630-Tower:~$ sudo systemctl enable nut-server
          Synchronizing state of nut-server.service with [[SysV][SysV]] service script with /lib/systemd/systemd-sysv-install.

  • NMC for UPS now working
    • Will adjust the details of the networking section of the NevisLabsSetup page to reflect additional changes

  • Setting up all the networking and devices
    • ctalab machine
      • # host odo
        odo.nevis.columbia.edu is an alias for ctalab.nevis.columbia.edu.
        ctalab.nevis.columbia.edu has address 10.44.2.10
      • Started ssh server following direction on this page:
        • https://linuxize.com/post/how-to-enable-ssh-on-ubuntu-18-04/
    • Smart UPS
      • # host nevis-ctalab-ups

      • account: admin
        password: ctaups
      • NOT WORKING CURRENTLY
  • Switched capacitors on test board to power Hamamatsu SiPM (Nancy)
    • Did this to accommodate higher bias voltage needed
    • C1, C3, C4: replace with 100nF, 100V (1206 package)
    • C5, C6, C7: replace with 2.2uF, 100V (1206 package)

  • Tried to find the network card for the UPS
    • Not located upstairs in the supply room as was initially thought
    • Found one that looked like it could be it in Bill's office, but not sure how it could've gotten there with Bill absent
  • Programmed the Aim TTi EL302P -USB PSU
    • added as a class of the dcps python package, new class called 'AimTTiEL302P"
    • can find the code at /home/ctalab/anaconda3/envs/cta/lib/python3.8/site-packages/dcps/AimTTiEL302P.py
      • So far implemented commands to do:
        • Write voltage
        • Write current
        • Read voltage
        • Read current
        • Measure voltage
        • Measure current
        • Turning output on/off
        • Checking if output is on
      • Start-up code is:
      • and then use the `aim` object to do all the commands
    • Still need to implement commands for
      • switching between local/remote (this isn't an option for the model we have)
