Lightning Shutdown-Long Version
This version is ideal for someone who is not as familiar with the lightning shutdown procedure. This has ALL the steps and locations of computers. For someone who is very familiar with lightning shutdown at the 90“ and who observes frequently, you might like the short version which is linked on the previous page.
Control Room: Telescope Control Workstation
Move the telescope to the stow position
Close the primary mirror covers.
Close the dome shutter. Hold button until you are sure shutter is closed. On the weather computer, in the box labeled Telemetry, you will see Dome State in bold. Underneath this, it should read closed. Please double check by looking (with a flashlight if the dome is dark), that the dome really is closed as well.
Stow the upper and lower wind screens.
Stow the dome.
Turn Dome switch to Manual.
Turn IIS switch to OFF.
Disable the telescope drive servos in TCS by hitting <F10> on keyboard.
Turn OFF the “Telescope Power”, “RA Oilpad”, “Main Comp” or “Aux Comp”, “Dec Preload”, and “RA Preload”. All of these buttons should now be green.
Switch OFF the telescope control console.
Turn OFF the “upper dome power” and the “dome motor power” switches. To the right of the AED, unplug one AC cable marked with red tape. This is the dome microphone, and may not have been plugged in.
At the TCS computer, select “Manual” from the “ShutDown” menu and follow the directions on the computer screen to close out of the TCS program. Hit enter until it exits.

Shutdown the TCS computer at Start Menu.
Close any open programs or windows & shut down the Autoguider Computer.

Turn off all the computers on the KVM computer except BOKPOP by pressing “scroll lock” twice and the number corresponding to the computer you want to turn off. You can also press the number on the Grey 8 port “TRENDNET USB/PS/2 KVM Switch” on top of the black computer rack and shut them down on the KVM computer. Either of these methods can work, it's just a matter of preference. Shut all of them down cleanly using their individual start menus.
NOTE: The 90” network now has a section that remains on during a lightning shutdown. This Always-ON-Network includes an UPS behind the wooden wall and several devices including BOKPOP. Please leave these devices powered on when doing a lightning shutdown.
The number associated with “bokccd1 BCSpec” computer is “1”
The number associated with “Bokccd2 90Prime” computer is “2”
The number associated with “Bokccd3 BC Spec spare” is “3”-this computer is not currently in the rack.
