Installation and Maintenance — K9203 996920302
- Install the module into an empty 19-inch rack slot and secure with front-panel screws; ensure unobstructed airflow (front intake, rear exhaust).
- Connect the 24 V DC power cable to the dedicated terminal; verify the power LED illuminates after power-on.
- Inspect fans quarterly for dust buildup; clean with a soft brush or compressed air (low pressure) to maintain airflow efficiency.
- Check the run monitor signal during routine maintenance to confirm proper fan operation.
- Replace fans every 3–5 years (based on operating hours) or immediately if abnormal noise or vibration occurs.
