CER Accelerometer Chassis Installed
Replaced the Endevco Accelerometer Power Conditioners with LIGO Accelerometer Power Conditioners. WP11653
Order in the rack:
U19 - Accelerometer Power Conditioner S2300062
U16-U17 AA Chassis S1300101
U14 - Accelerometer Power Conditioner S2300063
U13 - Accelerometer Power Conditioner S2300065
U12 - Accelerometer Power Conditioner S2300069
U11 - Accelerometer Power Conditioner S2300064
Still have EX, EY, MX, MY, FCES to complete.

Mid Y, we were not able to connect power, we installed the chassis and will revist.
Installed Accelerometer Chassis at EX, cables connected and chassis powered up. One of the Acelerometer cable connectors is loose and will be repaired later this week but it is functional.
Signal Order Asbuilt:
Slot = Cable Number = Accelerometer Number
1 = 4 = PEM EY BSC10
2 = 7 = PEM EY EBAY
3 = empty = empty
4 = 1 = PEM EY OPLEV
5 = empty = empty
6 = empty = PEM EY BSC6
7 = 6 =Black Cable
8 = 2 = PEM EY BSC10
9 = 3 = PEM EY TRN
10 = 5 = PEM EY BSC ACC X
We have no slot 10 on the new chassis therefore we moved cable 5 to slot 5, and moved the PEM EY BSC ACC X cable to match on the back.
Once we matched the cables we rearranged the signals to match the numbering on the front, i.e. cable 1 goes to slot 1, cable 2 goes to slot 2, etc...
Slot = Cable Number = Accelerometer Number
1 = 1 = PEM EY OPLEV
2 = 2 = PEM EY BSC10
3 = 3 = PEM EY TRN
4 = 4 = PEM EY BSC10 (this cable had a loose connector, but registered as an accelerometer)
5 = 5 = PEM EY BSC ACC X (this cable did not register as an accelerometer)
6 = 6 = Black Cable (this cable is unlabeled)
7 = 7 = PEM EY EBAY
8 = empty (This needs AA and signal)
9 = empty (This needs AA and signal)

Further investigation into EY Accelerometers
Slot = Cable Number = Accelerometer Number
1 = 1 = PEM EY OPLEV
2 = 2 = PEM EY BSC10_Y (Should be BSC10_ACC_X)
3 = 3 = PEM EY TRN (should be BSC10_ACC_Y)
4 = 4 = PEM EY BSC10_Z
5 = 5 = PEM EY BSC ACC X (should be TRN_TBL_ACC_Y)
6 = 6 = Black Cable (this cable is unlabeled) * same issue as EX
7 = 7 = PEM EY EBAY
8 = empty (This needs AA and signal)
9 = empty (This needs AA and signal)
Same as EX, CH2 moves to CH3, CH3 moves to CH5, CH5 moves to CH2.
Removed S2300069 from CS PEM rack, this is not supposed to be installed here.
