MDM Trouble Report for 2017 Dec 11

Telescope: 2.4m
Observer(s): Runnoe, Eracleous (UMich, PSU)
Instrument: OSMOS/R

Problem(s) Encountered:
We encountered a problem with the TCS computer during afternoon 
calibrations.  The issue was that the two TCS monitors (i.e. the
two on the right in the control room) were not getting a signal.
Both monitors had power, but shaking the mouse and typing did not
wake the computer to obtain a signal.  Both the DFM Engineering 
box and black MDC computer chassis in the left computer rack also
had green power lights on.  Observatory staff reported that the
computer was working fine in the morning.

Unplugging the HDMI cable from the rightmost monitor did not solve
the issue.  Rebooting the computer by pressing the yellow button 
behind the small lock door solved the problem.

While we were trying to troubleshoot the TCS computer issue, the
computer controlling the mirror airbags also reported errors.
Restarting the computer and support routine eventually solved this.
While it seems likely that this problem was caused when we were
trying to fix the TCS computer, we are reporting it just in case
it is indicative of a problem with the left computer rack.

Because it was cloudy during the first half of the night, we did 
not lose any time.
