The following chart shows the individual tests within the
bring up diagnostic. It also shows the halt codes, the
area tested, and the service aids to use in helping to
determine the cause of intermittent failures. (Use MAP
200 to diagnose solid failures during bring up.)
• Use the bring up diagnostic chart as a guide for
replacing cards on intermittent problems.
• Reseat all the cards and cables in the 5100.
• Disconnect the I/O devices attached to the 5100 I/O
interface port. If bring up diagnostics run to
completion, isolate to the I/O device causing the halt.
