4. If the system seems to be functioning correctly, but the circuit pack
does not start communicating with the system, replace the circuit
pack.
■ Green (test) — the system is running tests on this circuit pack.
■ Yellow (busy) — indicates that the circuit pack is in use.
NOTE:
A port circuit pack also lights its red LED when it performs
initialization tests (for example, when the circuit pack is initially
inserted into the system). If all initialization tests pass, the red LED is
turned off. If any initialization tests fail, the red LED remains lighted
and the circuit pack is not placed into service.
During the various states of operation (start-up testing, normal operation,
circuit failure, and so forth) circuit pack status LED indications appear as
shown in Table F-1.
