During the access I checked the gassiplex for the GEMs, it seems that a group of gassiplex does not respond. So I decided to try to replace it, but accelerator was almost ready when I came back with the spare electronics.
I left the GEMs on the side of S0 on the VDC. Changing the elecronics will take about 15 minutes, and 30 minutes to mount the GEMs back in place. So with opening and closing the doors I think I will need about 1 hour more of access to get them back.
I guess I will finish up during another access on the left arm maybe when switching to the different DAQ.
