2. Green (test)—the system is running tests on this circ uit pack.
3. 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 c ircuit pack is initially
inserted into the system). If all initialization tests p ass, the red LED is
turned off. If any initialization tests fail, the red LED remains lighted
and the circuit p ack is not placed into service.
During the various states of operation (s tart-up testing, normal op eration,
circuit failure, and so forth) c ircuit pack status LED ind ications appear as
shown in Table 1-8.
