Interrupt, Soft Reset, and SIMB/IMB Interface Verification Troubleshooting Flowcharts A-9 Flowchart 4 In Flowchart 4, LANDIAG evaluates that portion of the node directly related tocommunications on the LAN. Specifically, the LAN coprocessor, card^-to-LANinterface, and LAN attachment hardware are exercised. Other LAN features tested during self test include: i. multicast addressing 2. CRC generation/detection 3. MAU/ThinMAU jabber protection (coaxial cable connections only) 4. SQE disable operation (coaxial cable connections only) 5. heartbeat detection (coaxial cable connections only) If Flowcharts 1 through 4 pass with no faults indicated, the node hardware ispresumed good. However, marginal hardware faults may still exist, especially for coaxial LANconnections. These include MAU/ThinMAU faults that are difficult to detectby simply by bouncing test frames off the LAN cable. Marginal
