The ERNI connector is not central on the adaptor boards causing misallignment with the FEE. 

The adaptor board is 80mm long. The ERNI connector is 50mm long. The connector is 13mm from the 2x Lemo side and 17mm from the 3x Lemo side. This results in misallignment between the FEE and adaptor board. 

To correct for misallignment, 2mm will be skimmed from one of the rails on the FEE. 

Skimming the rail allows the FEE to now be inserted straight into the adaptor board connector. Attached image shows test FEE holder on the bench. FEE needs to be carefully inserted to make sure it is straight as it can now move around within the FEE holder with the 2mm skimmed off the rails. For CARME, where sight lines and space are limited, one person is required to hold and push in the FEE whilst another checks the positioning of the connectors is straight.
