VII. Installation and Maintenance Instructions

Installation: Rack: 4U standard cabinet, with fixed rails/screws, and reserved space for front and rear ventilation.

Desktop / Portable: Install optional foot pads and side handles for stable placement, avoiding blocking the ventilation openings.

Modules: Insert 3U PXI/CompactPCI modules when power is off, and tighten the fixing screws.

Power On and Operation:

Connect to 90–264 VAC, turn on the power switch, and the status LED will light up normally.

PC end install MXI-Express driver, and through MAX configuration, the module can be remotely controlled.

Daily Maintenance:

Cleaning: After power off, use a soft-bristled brush to clean the dust on the bottom intake and rear/top exhaust filters. Replace the fan filter regularly.

Environment: Avoid humidity, dust, and strong electromagnetic interference; operating temperature 0–50 °C. Electrostatic protection: When plugging or unplugging the module, wear an anti-static wristband to prevent the board cards from being damaged by static electricity.
