For investigating GND issue around IXV racks, we prepared a new AA chassis (JGW-S2213729)
Some jumper pins were removed in order to avoid local GND loops.
We will try to replace AA chassis and check the state of F3 GAS glitches tomorrow.
-----
JP1, JP2 (both 1-2 and 3-4), JP3 and JP6 (both 1-2 and 3-4) were removed for all 32 channels.
