Check magnet output connections in connector of magnet output cable, and inside the supply itself for the following SCE's:
MQP5C10- Found loose connections in both locations. Tightened and will continue to monitor current/voltage readback until later today. Leaving PTW-7785 open for now.
MQR2C08- Found nothing loose. Will check magnet connections inside the tunnel at next opportunity.
MQKAR06- Found loose connections inside the supply.

Body: 

"Blue Pig" ion pump power supply swapped out with Gamma SPCe.
SPCe ready for network support to run ethernet cable to connect to OPSSL17SW1.

Software can complete work on the control screen once the supply is connected.

Performed local test of installation. Ion pump would not start. Supply would not get above 50V then times out. This matches the behavior of this pump when on the old "blue pig" supply. Suspect issue with cable, pump, or vacuum downstairs. Will investigate issue next maintenance day with tunnel access.

Checked BPM system power supply and reseated current channel cabling for IPM2H01. Also verified system constants remained unchanged during the amplitude drop on the I channel.
