MAP 0120: LEDs Indicate a Fault
Diagnose a problem reported by the LEDs in the following sequence:
1. Use Table 2-2 to diagnose the error conditions reported by the system LEDs,
because these take precedence over the port LEDs. (For example, if the
system amber LED is on, it does not matter which port LEDs are on.)
Note: Throughout this manual, the term
system LEDs refers to the green (OK)
and amber LEDs on the left side of the IBM 2210.
This table is valid after power-on or Extended POST completes.
2. If the system LEDs appear to indicate no problem, go to Step 001 in the MAP.
