Frequently Asked Questions (FAQ)

• Q: Does the IS200AEPCH1CCB include a faceplate for VME mounting? A: No. The board is installed as a bare PCB using factory‑drilled conductive mounting points.

• Q: Are FPGA components user‑programmable? A: No. FPGA logic is factory‑programmed and aligned with Mark VI turbine‑control firmware.

• Q: Can the board be inserted or removed under power? A: No. The rack must be powered down to avoid backplane faults or component damage.

Field Installation Guidelines

• Maintain ESD protection during handling; FPGA and analog components are MOS‑sensitive.

• Ensure all conductive mounting points are properly grounded through the rack hardware.

• Verify daughterboard standoffs and screws are fully seated before energizing the system.

• Route wiring away from high‑voltage conductors to avoid noise coupling into turbine‑control signals.

• Confirm correct rack slot alignment to maintain backplane continuity.

• Inspect barcodes and identifiers for correct revision matching during replacement.
