Read GEs GEH instructions for the LCI in addition to how the excitation system and turbine controller interfaces with the static start control. Ensure cables are not shielded since the AC voltage can cause induced and circulating currents which ive heard of in the past burn the insulation. Verify all disconnect switch operation, ensure offline checks are working, ring out all feedback, controls, etc. before first crank. Ive seen the start up engineer put the exciter in sumilation mode and give the LCI a actual start. This would verify that all disconnect sequencing is correct in addition to the excitation system reference but not roll the unit. let me know if you need more specifics to help with your startup.
