LIGO Accelerometer Chassis chassis installed at EX, MX

Continued from ALOG75592 

Installed EX S2300070 - 9 channel Accelerometer Chassis

Installed MX S2300060 - 4 channel Accelerometer Chassis

Installed EY S2300073 - 9 channel Accelerometer Chassis

Installed MY S2300076 - 4 channel Accelerometer Chassis

Notes on install, MX was not completed due to power incompatibility, we need an adapter cable for this, same as MY.

Final cable arrangement listed below, many of the signals do not match the drawing D1300773, the following is as they were installed:

Front Cable - Accel Channel - Back Cable

Cable 7 - CH1 - OPLEV_ACC_Y

Cable 8 - CH2 - BSC10_ACC_Y (should be BSC10_ACC_X)

Cable 9 - CH3 - TRN_TBL_ ACC_Y (should be BSC10_ACC_Y)

Cable 10 - CH4 - BSC10_ACC_Z

Cable 11 - CH5 - BSC10_ACC_X (should be TRN_TBL_ACC_Y)

Cable 12 - Black cable to ??, magnetometer.  CH6 is empty on front, back is BSC6_FL_ACC_Z

Cable 13 - CH7 - EBAY ACC_Z

(TBI) - CH8 - 

(TBI) - CH9 - 

To fix this to match the DCC Drawing, CH2 moves to CH3, CH3 moves to CH5, CH5 moves to CH2.
