===========================

FAQ is below.

* Connect chamber to the stack.

* Prepare directory by:
  
  cd dcsnfs/ROC_Test/Stand1
  ./prepare_dir.pl

  # Stand1 is the main test stand. Stand2 is for intensive debugging.

* Power up the DCS board

  Nominal current 0.9-1.0 A

* Log in to dcs board and check firmware by

   ./ssh-dcs.sh
   exit

  If firmware version is below 150, update it by:

  ./flash_it.sh 

  If you are asked for password, it is "dcs".

* Login to dcs board and start feeserver by

  ./ssh-dcs.sh
  /dcsnfs/ROC_Test/feeserver_start
  ../restart_intercomlayer

  # This is necessary whenever you power up or reboot the DCS board.

* Power up the chamber

  Power up at main power supply.
  Nominal current < 0.6 A for all channels
  Total power consumption should be ~ 5 W in total at power supply indication.

* Shutdown and SCSN test.

  ./shutdown-test.sh
  see carefully the output. 

* Reset test.

  ./reset_test.sh
  see carefully the output. Number of MCMs shown should be
  either 138 or 104 for C1 and C0 chamber, respectively.

* NI, ORI, and Bridge tests through FEE server

  ./ce_test.pl 2    # for ni test
  ./ce_test.pl 3    # for ori test
  ./ce_test.pl 4    # for bridge test
  ./ce_test.pl 7    # for laser id test

  # log will go automatically to _current/ directory with date.
  # you can check tag definitions by "wing_showtags" command.
  # If it looks the test is crashed (or dead-lock), check whether
  # you did feeserver restart (mentioned above).

* Check the laser ids

  ./check_laser_ids.pl

* Prepare patch if necessary

  Patch file should be prepared 
  1. with datx format in _current/patch.datx
  or
  2. with  tcs format in _current/patch.tcs

  Then can be downloaded by do_init automatically (it askes afterward).
  You can also send only patch by:

   ./send_patch.sh

* Noise measurement with different digital filter conditions

  # No filter
  ./do_init nf
  ./opt_readout.sh t 100 Noise          ;# you can use also s instead of t

  # Pedestal filter
  ./do_init p
  ./opt_readout.sh t 100 Noise

  # Pedestal + Tail + Gain filter
  ./do_init pgt
  ./opt_readout.sh t 100 Noise

  # At each step, you can check the data quickly by:

  ./o32_plot.pl

  # Total power consumption will be like 115 W with "pgt" setup.
  # Should not exceed too much. More than 130 W will be some failure.

* PASA internal pulser measurements <THIS TEST IS NOT READY, SKIP IT>

  #  ./do_init p
  #  ./set_pasachm.sh even
  #  ./opt_readout.sh i 10
  #  ./set_pasachm.sh odd
  #  ./opt_readout.sh i 10

* External pulser measurement with only pedestal filter.

  Attach the pulser box to the cathode wire and chamber body.
  ./do_init p
  ./opt_readout.sh p 100 Pulser
  ./o32_plot.pl

  Here, all good channels should have ~4 RMS noise level.
  Channels with RMS < 2 should be checked.

* Long time stress test
  Disconnect Pulser Line and do:

  ./do_init p
  ./stress_test.sh 600 3

  # this is 3 times of 600 seconds length stress test (in total 30 minutes)

  If you run stress_Test.sh, A-ch LED (orange) on TTVvi should be turned on.
  If not, ask experts.
  Normally the chamber before cooling pipes needs one overnight stress test.
  After cooling pipes mounted, 1 to 2 hours is maybe enough.

* Ask for Cooling pipe mounting
  After it, do the same measurements with new directory.

<FAQ>

* ROB's crashes during the configuration

  Check the following:
  1. TTC trigger is stopped. If TTCvi has orange LED blinking, turn off the pulser or
     disable the trigger by TTC control software.
  2. Power is there ?
