6. Installation Notes & Maintenance Best Practices
   When installing the IC694PWR331C, verify that the backplane and cabinet are rated for the power and thermal load, and confirm that the power-supply rails are within spec before connecting. Ensure adequate clearance around the module for heat dissipation and maintain clean, organized wiring to prevent accidental disconnections during maintenance. Periodically inspect the module’s connectors and cabinet air passages to prevent heat buildup and to sustain stable output. Monitor the power supply’s status indicators during startup and normal operation to detect abnormal conditions early. If firmware or configuration utilities exist for RX3i power modules, perform updates in a controlled test environment before field deployment to avoid destabilizing the rack’s power architecture. Keep spare units on hand to minimize downtime in critical production lines and document any changes in the rack’s power topology for faster troubleshooting.
