Maintenance Object Repair Procedure
d. A Control Channel Protocol error has occurred. This may be due to the
circuit pack detecting an on-board hardware failure. Execute busyout
board UUCSS and reset board UUCSS commands to reset the circuit
pack. Any such problem will be detected during initialization, as the circuit
pack locks up and appears insane to the system.
e. An extra TN771D circuit pack has been inserted into the port network.
f. An on-board hardware failure has been detected by the circuit pack. Enter
the busyout board UUCSS, reset board UUCSS, and release board
UUCSS commands to reset the circuit pack. If the SAKI Sanity test (#53)
passes, the circuitry is healthy. If not, replace the circuit pack.
g. This error is reported by the circuit pack when it detects a program logic
error. While no action is required, this error may lead to errors of other
types being reported against this circuit pack.
h. This error is reported by the circuit pack when it cannot update NPE
memory and read it back. This error type can be ignored, but may lead to
errors of other types being reported against this circuit pack.
i. Excessive number of messages have been received from the
Maintenance/Test circuit pack. This may be due to a hardware problem on
the circuit pack. The switch will take the board out of service and
periodically put it back into service to see if the problem has disappeared.
If the problem persists, replace the circuit pack.
j. This error is not service affecting. No action is required. This error is
reported by the circuit pack when it receives a bad control channel
message from the switch.
k. Error type 3999 indicates that the circuit pack sent a large number of
control channel messages to the switch within a short period of time. If
error type 1538 is also present, then the circuit pack was taken
out-of-service due to hyperactivity. If error type 1538 is absent, then the
circuit pack was not taken out-of-service, but it has generated 50% of the
messages necessary to be considered hyperactive. This may be
completely normal during heavy traffic periods. However, if this error type
is logged when the circuit pack is being lightly used, it may indicate a
problem with the circuit pack or the equipment attached to it.
