1. Retry the command at one-minute intervals a maximum of five times.
2. If the test continues to abort, escalate the problem.
FAIL There is a problem with one or both port carrier power units on the tested
carrier.
1. For each port carrier power unit that has all status LEDs OFF, check
the DC input to the port carrier power unit at the port carrier power unit
outlet (see Figures 11-19 through 11-22). If there is no DC, then check
the appropriate circuit breakers for the affected port carrier power
unit. If the circuit breaker has tripped (that is, it is in the down
position), reset the circuit breaker. If the circuit breaker trips again or
DC is not present at the port carrier power unit outlet, there is probably
a power wiring problem in the cabinet. Follow normal escalation
procedures.
2. At this point, DC should be present at the port carrier power supply
outlet. If the carrier being tested is the 1A or 2A carrier, or the 1B
carrier in a High or Critical Reliability system, refer to"Troubleshooting
Control Carrier Power Units"" in Chapter 5, "Routine Maintenance
Procedures". Otherwise, use the recycle carrier PC command (where
PC is the appropriate port network and carrier) in an attempt to bring
back the power units for this carrier. If the test passes, the trouble is
cleared. If the test does not pass, one port carrier power unit, or both,
in the tested carrier is defective.
If only one port carrier power unit is defective, the status LEDs on the
healthy port carrier power unit light green for a moment. When the recycle
test determines that both port carrier power units are defective, the
software turns off power to both the good and defective port carrier power
units. This causes the status LED(s) on the good port carrier power unit to
light red.
