-====== Schulman Telescope Shutdown Procedure ======
+====== DO NOT USE THIS PROCEDURE ======
 The steps to shutdown the telescope are somewhat the reverse of the [[schulman_telescope_startup_procedure|Startup]] process- but greatly simplified. Knowledge of the Startup process as well as [[public:catalinas:lemmon:schulman_32:using_the_lcogt_gui_and_moving_the_telescope|using the LCOGT GUI and moving the telescope]] are assumed in the steps below.
-The final state of the shutdown in terms of electrical isolation (lightning shutdown) and protection from the elements (covering the telescope with plastic, rotating the dome to minimize weather effects of rain and snow etc...) are not covered in totality here. Please confer with mountain operations staff and cognizant observers and operators for more information.
  ==== Telescope and Dome ====
   - Close the telescope Mirror Covers.
   - Close observatory Dome (if not already closed).
   - Park the telescope (or move it to the park position and turn the tracking off). Make certain telescope is not tracking.
-  - Remove instrumentation- or if left in place, cover the primary mirror baffle tube with baffle cover. It is a good idea to leave the telescope in a balanced state.
+  - Make sure to leave the telescope in a balanced state. This means either with the camera on or the Eyepiece and weights on.
   - Rotate Dome (any method) to chosen safe position. Park position is currently at 59 degrees [[public:catalinas:lemmon:schulman_32:review_of_astronomical_coordinates|Azimuth]].
+  - Press the red button on the {{:maxdome_controller_box.jpg?linkonly|dome controller box}} to cut power to it.
-=== Disconnect/Disable Devices (Software)===
+==== Main Computer Software ====
   - On the main observatory computer {{:acp_connect.jpg?linkonly|disconnect the telescope via ACP}} (if connected) and TIM unit.
-  - Physically turn off the {{:tim_unit.jpg?linkonly|TIM unit}} at its rocker toggle switch.
+  - Close any running software on the desktop. (Though do not turn it off the computer just yet)
-  - Press the red button on the {{:maxdome_controller_box.jpg?linkonly|dome controller box}} to cut power to it.
-  - Close any running software on the desktop.
 ==== Controller Shutdown ====

   - Open a terminal using either the terminal icon at the top of the desktop or by Right Clicking on the desktop as shown below:
   - {{:lcogt_desktop_shutdown.jpg?1200|}}
-  - At the prompt in the new terminal window type "sudo poweroff" -> This will shutdown PubSub.
+  - At the prompt in the new terminal window type ''sudo poweroff'' -> This will shutdown PubSub, you will know it works when the VNC screeen freezes or shows "Disconnected".
   - Using VNC access the MIC computer.
-  - Open a new terminal and again execute "subo poweroff"
+  - Open a new terminal and again execute ''sudo poweroff'' just as on PubSub
-  - Wait 2 minutes (to make certain these computers shutdown "nicely")
   - Turn the {{:telescope_controller_switch.jpg?linkonly|red controller switch}} to "Off"
-==== Main Computer and UPS's ====
+==== Main Computer Shutdown====
+Now you can turn off the Main Computer via whatever method. Make sure it's off (and not installing updates) before proceeding.
+==== UPS Shutdown ====
+Turn off the Large UPS by pressing the "power" button. Turn off small UPS, this requires pressing and holding for a moment.
+{{:public:catalinas:lemmon:schulman_32:power_big_ups_off.gif?direct|}}
+{{:public:catalinas:lemmon:schulman_32:power_ups_off.gif?direct|}}
+Unplug both UPS's from the wall now that they are off.
+{{:public:catalinas:lemmon:schulman_32:power_big_ups_unplug.gif?direct|}}
+{{:public:catalinas:lemmon:schulman_32:power_ups_unplug.gif?direct|}}
+In Warm room unplug the ethernet cable that give service to Controller. This is to protect it from any lightning travelling through the ethernet cable (RIP Phillips in 2019).
+==== It's a Tarp! ====
-  - Turn off the Large UPS (for telescope controller) by pressing the "power" button. The screen indicates the instructions.
+Consider covering the Telescope and main computer desk with tarps. The desk should be quite easy but the telescope can be challenging. If you do not have a helper or are simply unable to do so make sure to inform mountain operations.
-  - Unplug the Large UPS from the wall.
-  - Shutdown main observatory computer.
-  - Turn off small UPS (for computer and remote power outlets).
-  - Unplug from power source.
-  - In Warm room unplug the CAT5 cables that give service to the main observatory computer and the telescope controller.
-  - Consider covering telescope, observatory desk and television.
