Installation Guidelines

CRITICAL WARNING: This equipment is sensitive to electrostatic discharge (ESD). Always use a grounded wrist strap and handle the module by its edges. Ensure all power to the S5 rack is de-energized and locked out before installation or removal.

1 Verify that the target S5-155H rack is completely de-energized and follow all site-specific Lockout/Tagout (LOTO) procedures.
2 Identify the designated CPU slot in the chassis. Ensure the slot is free of dust, debris, and any obstructions on the backplane connector.
3 Carefully align the module with the card guides in the slot. Slide the CPU into the rack until the backplane connectors make firm contact. Do not force the module.
4 Secure the module in the chassis by tightening the retaining screws on the front panel. Ensure a snug fit to maintain proper electrical connection and grounding.
5 Once all modules are securely installed, remove LOTO devices and re-apply power to the rack. Verify CPU status indicators for correct operation.
