We have found some problem with FPGA MPN# EP4CGX30CF23I7N PCBA Serial : FBNRK00219060130 Found low resistance between pin F7 vs B2 = 174.2 Ohm

Verification steps:- 1. Component level found only resistance lower than known good unit. 2. FPGA fail on module level with symptom OSC loopback fail, during circuit pack test, the optical service ...
