050000481-02 identifies the LS197/2 legacy communication card. The LS197/2 designation, full numeric reference and installed host configuration should remain together throughout replacement planning.

Communication cards can depend on interface hardware, addressing, software and backplane generation. A replacement therefore requires a connector-level and configuration-level comparison instead of a family-name match alone.

• Provides a controlled identity for LS197/2 service enquiries.
• Keeps the -02 suffix and board revision visible in the replacement record.
• Places connector and communication configuration checks ahead of substitution.
• Supports comparison of host slot, cable termination and interface settings.
• Avoids importing specifications from later LS197 variants.

• Match 050000481-02 and LS197/2 on the installed card.
• Verify host chassis, slot, backplane and processor generation.
• Compare physical ports, connector pinout and cable assemblies.
• Record network addresses, communication settings and software configuration.
• Do not use specifications from LS197/6 or another later variant as proof of interchangeability.

• Archive the communication configuration and machine project before shutdown.
• Label cables and photograph switch, jumper and connector positions.
• Handle the card with appropriate antistatic controls.
• Inspect the host connector and cable condition before fitting the replacement.
• Verify communication status, diagnostics and machine data exchange after startup.
