Removing FEB cooling plate from SVT box to rework FEBs.

System status (from Ben's email Jan 7th):
We can currently power 8 FEBS. We can power every hybrid attached to those 8 FEBS: 30 Hybrids. All Hybrids that we can power are able to sync, except for FEB 8, Hybrid 2, which has just 1 APV that won’t sync.
Link to excel file. 

L1t (which was GUI FEB #0) has what looks like a short on the output side of the regulator on DVDD (we can’t see the short probing the pins from outside).
L6b (which was GUI FEB #7) first appeared to have a short on DVDD. After 5mins and a power cycle it came back with current levels that looked reasonable except that the DVDD level indicated it had no control link.
