Necessary hardware for connecting data and timing
The detector will be connected to the MM to SM converter box (input LEAP0) using the 24 channel type B cable. LEAP0 LANE[3:0] and LANE[7:4] ports will be connected to the data acquisition server. LANE[11:9] (namely lane 11) will be connected to the LCLSII timing system using the MTP fiber breakout. The MM to SM converter box has to be as close as possible to the detector.
To connect the detector to the cooling system, use the hardware mentioned here.
