REBOOTING THE CCD CRATE  

Procedure

There are two situations: the crate is stuck midway through a boot, and the crate is up and running but needs to be rebooted anyway. These are distinguished by the crate prompt as described below:
  1. Log in to kanaha as esieng
  2. Execute the command 
    	telnet tserver4 3005
    to open a TIP line to the CCD VME crate.
  3. Press the RETURN key a couple of times to get a prompt.
  4. If you see: 
    	[VxWorks Boot]:
    then the system is hung at the boot prompt. Type "@" (without the quotes) and a carriage return to reboot the crate. If, instead, you see: 
    	->
    then type reboot followed by the RETURN key to intiate a normal reboot. If you get no response, you need to ask someone on the summit to power cycle the ESI VME CCD crate in the Keck II computer room.
  5. You will see things scrolling by till reboot of crate s/w is complete. The end of the sequence is signalled by: 
    	Done executing startup script /vx/esi5ce/startup.cmd
	Got network configuration
	Broadcast message sent on ln0
	Broadcast not sent on lo0
  6. Press Ctrl ] to return to the telnet prompt, and type quit to terminate the telnet session.
  7. At the kanaha prompt, run the testAll command. This will ping the CCD crate (esi5ce) to make sure it is up, and will check some CCD keywords to make sure they are reporting properly (it also tests a number of other, non-CCD things).
  8. Type fix_stuck_ccd. This resets relevant exposure parameters to the values they should have when no exposure or readout is in progress.
