Spares available: 3
Digitizers:
- SN 067h - errors on bits 9 and 10 with rate >100 kHz
- SN 02Eh - errors on bit 12 with rate ~4 kHz
- SN 097h - the card is blowing the fuse for the 5V

Configuration files for decompostion
The configuration for the decomposition is here: https://wikihost.nscl.msu.edu/gretina/doku.php/daq:decomp
Positioning of the quads
When a position of a detector is changed the following has to be updated:
- CS_GblId in /global/boot/vmeArray/vme*.cmd — The Id is given by hole_number * 16 + position_in_quad * 4 + board_number
- GTSort_shack/DetNum.dat — self explanatory
