TROUBLE SHOOTING

BROKEN SISPI INTERLOCKS
Sometimes the Interlock and OCS lights will turn red, because of a broken interlock.  When this happens, no images can be taken.  If you notice a broken interlock, first visit the "Interlock Viewer" page, which is one of the GUIs up on the observer1 console:

http://system1.ctio.noao.edu:7001/apps/interlock_viewer/ [1]

Click on the SISPI light blue box in the upper half of the page.  This should fill the lower half of the page with SISPI Interlocks.  Make a note of which of the Interlocks is highlighted in red.

1.  OCS Status -- if the OCS Status is the *only* one that is red, go to the Observer Console GUI, click on the System Control tab, and hit the "Refresh" button.

2.  If the OCS Status + Another Process (eg., FCS_STATUS) shows up in red, go to the "Alarm History" page, which is one of the GUIs up on the observer1 console:

http://system1.ctio.noao.edu:7001/apps/alarm_history/ [2]

Identify what the specific alarm is (for example, check the time of the alarm to isolate the alarm that caused the interlock to break).  In most cases, the Alarm History page will provide more details than the Interlock Viewer page. 

Once you have identified the component that has failed, go to the "Architecht Console" page, which is one of the GUIs up on the observer1 console:

http://system1.ctio.noao.edu:7001/apps/architect_console/ [3]

Find the component that has failed on the left side of the page, and highlight it.  Click on the "Full Log" button on the middle, right part of the page.  A terminal will pop up with a log history.  Scroll all the way to the bottom of the terminal and verify that there is indeed a problem with the component.

Then, hit the "restart" button under "Role Control" in the top, right part of the Architect Console.  Make sure that a red cross appears before the component that was just restarted--this means that the restart worked.  Wait a few seconds for the red cross to become a green check mark.

Lastly, go to the Observer Console GUI, click on the System Control tab, and hit the "Configure" button.

TURNING OFF THE LEDS MANUALLY
1.  Go to the Architect Console:

http://system1.ctio.noao.edu:7001/apps/architect_console/ [3]

2.  Find the System Control Box.  Replace the boxes that say:

Component         Device           Command: Press Enter When Complete

with:

DECAL            DECAL            set leds off
