Lightning Shutdown Procedure
1.3-m McGraw-Hill Telescope

(DO NOT TURN OF SWITCH and SMALL UPS)

Last updated September 06, 2007

NOTE: IF THERE IS NO OBSERVER AT THE 2.4M TELESCOPE, THE 1.3M OBSERVER IS RESPONSIBLE FOR A LIGHTNING SHUTDOWN AT THAT TELESCOPE ALSO.

Walk through these procedures at the beginning of your run. If you have any questions about how they work, please ask. After hours call Bob or Steven (phone numbers on the cork board, back wall). Lightning is a serious concern, and in an emergency do not hesitate to call anytime.

1. Stow the Telescope

If observing, follow the usual closing procedure. Stow the telescope at zenith, close the instrument hatch and mirror cover. Then close the dome, and turn off the telescope power at the console in the dome. (Note: The telescope drives are not powered by the UPS.)

2.Shut Down Computers

  1. If using etna (MDM8K), login to the console as user "shutdown", password "haltsystem", and it will turn itself off.

  2. If using tambora, located in the left computer rack (ccdcom), login to the console as user "shutdown", password "haltsystem", and when it stops the shutdown process, turn off the power using the switch on the back of the box next to the AC power cord.

  3. Power off the Linux workstations mcgraw and hill by logging in as a regular user and typing "shutdown" at the Unix prompt. Answer "Y" at the prompt. They should turn themselves off.

  4. If using CCDS or TIFKAM, quit out of the data-taking program on the IC (type "quit" at the prompt), then turn off the power on the PC after you see the DOS prompt return.

  5. The guider PC is on the observer's table to the right of the observing console monitors. Exit the guider program by typing "x" and then "x" again, followed by the ENTER key. Do not turn off the guider PC. (Step 4 below takes care of that.)

3 TCS PC & Power supply (middle right computer rack):

CAUTION: Do these steps in order:
  1. [Omit these steps only in an emergency] There is a TCS mouse next to the TCS monitor in the control room. To shutdown the TCS control program, left click on the little yellow icon at the upper left of the TCS montor screen and select "Close" on the drop down menu to close the TCS program. Then click on "shutdown" at the bottom of the screen. When a workplace shell appears click "ok" and wait for the machine to finish shutting down.

  2. When it says it is safe go to the computer room and turn off the TCS PC, switch on the front panel of the TCS PC.

  3. Finally, turn off the TCS power supply)vertical silver switch to the right of the red light), which is just below the TCS PC. Do Not turn the TCS power supply off until the TCS computer is OFF

4. MIS Controller and Telescope Encoder Cables

5.Turn Off UPS Power

In the computer room on the south (left-hand) wall there is an electrical box marked UPS. Open it and turn off the Main Breaker (marked in red). This will kill all the power to the computer racks and the instruments on the telescope.

TO RESTART DO EVERYTHING IN REVERSE ORDER

  • Make sure that the RA, DEC, and Dome cables are reconected and that the MIS and Autoguider power is turned back on.
  • Turn on the TCS power supply below the TCS PC before turning on the TCS PC.
  • If using the CCDS or TIFKAM, make sure you power up the relevant computers in the correct order.

    Also remember to turn tambora, mcgraw and hill back on the power switches are on the front panel. Check the instrument and telescope for correct operation. If using a CCD, take a test exposure to be sure the shutter is opening and light is reaching the detector.
