MDM Trouble Report for 2013 Oct 23

Telescope: 1.3m
Observer(s): Eric Gaidos (University of Hawaii)
Instrument: B4K

Problem(s) Encountered:
Prospero window froze.  No error messages in any of the terminals.
Restarted Prospero.  Would not complete connection to IC.  
Rebooted IC.  Would not reboot - no signal to either terminal.
Tried multiple reboots - beeping alarm sounded after one try.  
Swapped out spare IC from 2.4m.  Discovered that fiber optic
sequencer board was mounted at incorrect angle due to broken
flange and improvised mounting screw hole and that this angle prevented 
the fiber optic cable B from being attached.  Removed screw
to allow board to assume normal angle.  Successfully attached
fiber optics.  Good boot, all systems normal, however bias shows
horizontal random striping (not fine grain noise, but bars of 
varying width and 100-300 dn) for all four quad amps.  Tried 
seqinit and restrating on mcgraw.  No effect.  Opened IC back
up and verified that board was in place, wiggled a bit, and
propped it back into its original (out of place) angle.  
Rebooted IC.  Did this twice.  Problem with readout persists.  
Called it a night at 9:30 PM.
