Installation and Maintenance
Installation Preparation:
Verify compatibility with Mark IV racks and ensure proper grounding. Align the 13-pin connectors and ribbon cable with mating ports on the motherboard (e.g., DS3800DECA1B1B1) and secure them using retention latches. Route signal cables away from high-voltage lines to minimize EMI. Conduct a power integrity test to confirm 24V DC supply stability before powering up the module.
