While mounting OEPs

  • A list containing all serial numbers has to be maintained, unfortunately the database is neither up-to-date nor complete. A form to write down all necessary information will be prepared (Kathrin?).
    • serial number of OEP
    • serial number of Motherboard
    • serial number of all 4 / 6 daughterboards
  • Please check especially the serial number of the OEP twice since it is vital for the readout system - inconsistencies will prevent DAQ from starting up properly.

Open questions

Line: 49 to 54
 
  • How long should the cables be?
    • The front side of the chamber remains to be equipped with the new optical fibres - should they be short or should one be able to later connect them to the readout?
      • For the test system the optical fibres should be long enough, to place the TRB below the chamber between the rails of the mainframe. Once they get replaced, they need to be long enough, to be connected to the readout at the final position. Which is for the outer chambers in the mainframe (if seen in beam direction, front frame left and right lower corner of yellow frame), for the inner ones below the front platforms. (JW, 17.4.2009)
