[Gerardo, Kyle, Chandra]

This afternoon we reconfigured GV11's gate annulus ports (two 1-1/3" mini CFF half nipples). The (building) north side port is blanked off and the south side has a metal valve, all leak tight. We pumped out the gate annulus, knowing there is an outer o-ring leak; the right angle valve will remain in place during the CP4 bake.

To do this exercise we valved in small IP connected to CP1 and soft closed GV10, and then valved out IP9 and valved in main turbo pump. Y1-arm pressure alarmed temporarily. Valves are back to normal configuration (GV10 open, turbo valved out, IP9 valved back in). CP1's IP is still valved in.
