Installation Guidelines

1. 1 De-energize System: Completely power down the S5 rack and verify zero energy state using a calibrated voltmeter before proceeding. Apply appropriate LOTO devices.
2. 2 Handle with ESD Precautions: Use a grounded wrist strap and handle the CPU module by its edges to prevent electrostatic discharge damage to sensitive electronic components.
3. 3 Install in Designated Slot: Identify the correct CPU slot in the S5-155H chassis. Align the module with the card guides and slide it gently into the backplane until the connectors make firm contact.
4. 4 Secure the Module: Fasten the module's retaining screws or locking mechanism to secure it firmly in the chassis. Ensure there is no movement.
5. 5 Connect Peripherals: Reconnect any necessary programming cables, communication links, or battery backup modules to the CPU's front panel interfaces.
6. 6 System Power-Up: After verifying all connections are secure and the work area is clear, remove LOTO devices and re-apply power to the system. Monitor the CPU's diagnostic LEDs for correct startup status.
