Supports hot-swap replacement where the system configuration permits
Application Scenarios: Gas turbine power generation, steam turbine power generation, combined-cycle power plants, and industrial drive systems.
Installation Requirements: Insert into the Mark VI/VIe cabinet standard backplane slot. Wear an anti-static wrist strap before insertion to prevent ESD damage. Locking-screw torque: 3.5 N·m.
Usage Notes: Purchase spares only from GE-authorized channels to ensure version compatibility. Back up the current configuration in the control system software before replacement. Store boards in anti-static bags with humidity controlled at 30%–70% RH. Do NOT plug or unplug the board while powered, unless hot-swap is supported and safety is confirmed.
