   * NMC for UPS now working
      * Will adjust the details of connection page to reflect additional changes

   * Setting up all the networking and devices
      * ctalab machine
         * # host odo<br />odo.nevis.columbia.edu is an alias for ctalab.nevis.columbia.edu.<br />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<br />nevis-ctalab-ups.nevis.columbia.edu has address 10.44.1.204
         * account: admin<br />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 [[https://github.com/sgoadhouse/dcps][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:
            * from dcps import AimTTiEL302P
            * aim = AimTTiEL302P ('ASRL/dev/ttyACM0::INSTR')
            * aim.open()
         * 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)
