• Physical Form Factor: Half-Height Module Slot

Hardware Specifications

Mechanical Monitoring and TSI Integration

In 3500 System racks, maintaining proper airflow and rack integrity is essential for the reliability of eddy-current probe scaling and rotor dynamics monitoring. The 128277-01C plate serves as a mechanical barrier that prevents debris ingress, ensuring that active modules operate within designed thermal limits. By sealing empty slots, the faceplate helps maintain consistent internal chassis pressure and contributes to cross-talk suppression by preventing unauthorized or accidental access to the backplane communication pins. Proper placement ensures that the overall TSI framework remains compliant with original electromagnetic interference (EMI) protection standards.

Ordering Info

• 1 128277-01C Half-Height Faceplate

• 2 Captive mounting screws (pre-installed)

Field Installation Guidelines

• Rack Preparation: Verify that the target rack slot is empty and clear of any obstruction or loose cabling.

• Alignment: Position the faceplate against the rack front panel guides, ensuring the alignment pins engage with the rack frame.

• Securement: Tighten the captive mounting screws to the rack frame using a standard flat-head screwdriver. Do not exceed 0.5 Nm of torque to prevent deformation of the rack rails.

• Verification: Ensure the faceplate sits flush against the adjacent modules to maintain the rack's continuous environmental seal.

Frequently Asked Questions

• Does the 128277-01C provide any electrical shielding?

  The plate acts as a mechanical cover. While it provides basic physical obstruction, it does not provide active RFI/EMI shielding beyond standard metal chassis enclosure properties.

• Is this faceplate compatible with full-height module slots?

  No. This component is specifically designed for half-height slots. Attempting to force it into a full-height slot will result in improper fitment and lack of mechanical retention.

• Does this module require internal rack wiring?

  No. The 128277-01C is a purely passive mechanical component and does not connect to the 3500 backplane or any internal rack wiring harnesses.

• Can I replace a functional module with this plate?

  This plate is intended to cover empty expansion slots. It should not be used as a replacement for active functional modules, as it lacks the necessary backplane interface electronics.

• What is the purpose of the captive screws?

  The captive screws ensure that the hardware remains attached to the faceplate, preventing small parts from falling into the chassis during installation or maintenance.

• Can this be used in 3500/05 or 3500/15 racks?

  Yes. The physical slot dimensions for half-height modules are standardized across all 3500 Series rack configurations, regardless of the power supply or processor type.

• Is it necessary to power down the rack to install?

  No. As a passive mechanical component, installation does not require de-energizing the rack, provided that caution is taken to avoid contact with active backplane connectors.

• What defines the "Future Expansion" designation?

  The term refers to the plate's role in reserving slot space for potential future system upgrades or module additions without compromising the enclosure's integrity.
