J. Kissel, R. Mittleman While at the X-end investigating the HPI pump failure, WE remembered to put the jumper back. This is inside the Corner 1 T240 Interface chassis, S1201388 in U21. I attach a few pictures. Pg 1 shows the internal board and the jumper in the upper left corner marked GND Shield. It's engaged in the picture. Pg 2 shows the rack number Pg 3 shows the serial number
