System Startup =============== Once the instrument has been unpacked and cabled, begin startup from System Powerup. Subsequent (nightly/daily) re-startup should generally begin from “Preparing For Operation” below. The following assumes you're sitting at the AOC workstation, but it could be done anywhere with appropriate network tunnels. When one must SSH to different hosts, the one where the command should be run will be indicated before the prompt, like ``[xsup@exao1 ~]$ ls`` to run ``ls`` on AOC in the ``~`` directory. (Don't type the ``[host $]`` prompt, or any comment lines starting with ``#``.) You should run these commands as the user ``xsup`` to ensure you can read shared memory images (shmims) and ``ssh`` around to RTC and ICC. If sitting at AOC, it's therefore best to be logged into the desktop as ``xsup``. If working remotely, note that steps in RTC and ICC power-up must be done from firefox running on AOC. You can use ``ssh -X`` to accomplish this with the right command line option in firefox, but using the x2go virtual desktop is generally easier. System Powerup -------------- 1. Start the MagAO-X processes on AOC (exao1) to get power control (see the `guide to xctrl <./software/utils/xctrl>`__ for more detail) :: [xsup@exao1 ~]$ xctrl startup # you'll see some output as the processes start, wait a little bit [xsup@exao1 ~]$ xctrl status # verify processes are all green/running 2. You should have power control now. AOC talks over the instrument internal LAN to network-controlled power strips (PDUs), which you can control over INDI via several different interfaces: **sup**, **cursesINDI**, or **pwrGUI**. Since you're sitting at AOC, it's simplest to open **pwrGUI**. You should see switches appear. :: [xsup@exao1 ~]$ pwrGUI & # window should pop open with switches 3. The following devices on the *ninja* tab of **pwrGUI** should be powered up, and *never* powered off (unless you know what you're doing): - ``pdu0.dcpwr`` - ``pdu3.blower`` - ``pdu3.rackfans`` - ``pdu3.instCool`` - ``usbdu0.rhtweeter`` - ``usbdu1.rhncpc`` The ``camflowfs`` and ``camllowfs`` power should also be turned **on** (at least long enough to follow the ICC Power-On steps below). 4. RTC Power-On #. **Critical:** Ensure that ``instCool`` is powered on to provide liquid cooling to the RTC. #. Using the **pwrGUI** *ninja* tab, power on ``pdu0.comprtc`` #. Using Firefox on AOC, navigate to http://192.168.0.170/ (or use the "Moxa DIO" bookmark) #. Log in (if required); password provided to those who need it #. In the left menu, select :menuselection:`I/O Setting --> DO Channels` |image1| #. In the main frame, click on :guilabel:`RTC-PWR`, which will open a new window: |image2| #. Under :guilabel:`1. Current Setting`, ensure that :guilabel:`Pulse Output` is selected, and check the box under Pulse Start. Then press the :guilabel:`Submit` button at the bottom. This remotely presses the ATX power button on the RTC. #. Wait for RTC to come up, and verify that you can ssh in .. note:: If connecting from off-site, you can set up a tunnel to the Moxa DIO device by running:: ssh -L8787:192.168.0.170:80 YOURUSERNAME@exao1.magao-x.org (substituting your MagAO-X username appropriately). The interface is then available at http://localhost:8787/ 5. ICC Power-On #. **Critical:** Ensure that ``instCool`` is powered on to provide liquid cooling to the ICC. #. Using the **pwrGUI** *ninja* tab, power on ``pdu0.compicc`` #. Using Firefox on AOC, navigate to http://192.168.0.170/ (or use the "Moxa DIO" bookmark) #. Log in (if required); password provided to those who need it #. In the left menu, select :menuselection:`I/O Setting --> DO Channels` #. In the main frame, click on :guilabel:`ICC-PWR`, which will open a new window similar to the one for RTC-PWR. #. Under :guilabel:`1. Current Setting`, ensure that :guilabel:`Pulse Output` is selected, and check the box under Pulse Start. Then press the :guilabel:`Submit` button at the bottom. This remotely presses the ATX power button on the ICC. #. Wait for it to come up, and verify you can ssh in #. Ensure the LOWFS camera driver loads by running ``sudo modprobe pvcam_pcie`` (we plan to automate this eventually, but it's always safe to do again) #. **Optional:** If you don't plan to use the LOWFS cameras any time soon, you can power them back off. See :ref:`missing_lowfs` for hot-plugging instructions if you need to power them on later. Software Startup ---------------- 1. RTC - ssh to RTC with ``ssh rtc`` - First start cacao processes. This is done with a startup script in the cacao directory: :: [xsup@exao2 ~]$ cd /opt/MagAOX/cacao [xsup@exao2 cacao]$ bash ./startup - Use ``milk-fpsCTRL`` to verify that both ``dmch2disp-00`` and ``dmch2disp-01`` are running - Now start MagAO-X :: [xsup@exao2 ~]$ xctrl startup - Use ``xctrl status`` to verify that processes have started. 2. ICC - First start cacao processes. This is done with a startup script in the cacao directory: :: [xsup@exao3 ~]$ cd /opt/MagAOX/cacao [xsup@exao3 cacao]$ bash ./startup - Use ``milk-fpsCTRL`` to verify that ``dmch2disp-02`` is running - Now start MagAO-X :: [xsup@exao3 ~]$ xctrl startup - Use ``xctrl status`` to verify that processes have started. 3. It is possible that MagAO-X software startup will not complete correctly, and/or need to be re-done. Symptoms include not seeing either RTC or ICC (or both) processes in INDI on AOC, or crashed xindiserver processes (isICC or isRTC). The cause is elusive. The fix is to shutdown and restart MagAO-X software (``xctrl shutdown --all``) on each machine – possibly also on AOC. You do not need to shutdown the cacao processes. GUI Setup --------- - To setup the GUIs on exao1 (AOC) as user ``xsup``, run the command: :: [xsup@exao1 ~]$ magaox_guis.sh - Some windows will need to be rearranged. The DM displays should self-normalize. If they do not, the following command should fix it: :: [xsup@exao1 ~]$ bash dmnorm.sh tweeter & where you replace `tweeter` with either `woofer` or `ncpc` as necessary. - Set up a :doc:`cursesINDI <./software/guis/cursesINDI>` terminal. Preparing for Operations ------------------------- You can now proceed to :doc:`daily_startup` to prepare the instrument for operation. .. |image1| image:: figures/moxa_dio_do.png .. |image2| image:: figures/moxa_dialog.png
