b. The circuit pack has been busied out via the
busyout board UUCSS
command.
c. This error indicates communication problems between the switch and this
circuit pack. Execute the
test board UUCSS
command and refer to the
repair procedures for Control Channel Loop-Around Test (#52).
d. An on-board hardware failure has been detected by the circuit pack.
Reset the circuit pack by executing
busyout board UUCSS
and
reset
board UUCSS
commands. If there is a problem, it will be detected during
initialization and will cause the circuit pack to lock up and appear insane
to the system. See the repair procedure in footnote (a).
e. 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.
f. 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.
g. A critical hardware failure (one or both of the data processors are insane)
has been detected on the circuit pack. Reset the circuit pack via the
busyout board UUCSS
and
reset board UUCSS
commands. If the circuit
pack Restart Test (#594) passes, then the on-board circuitry is healthy.
Retire the alarm via the
test board UUCSS long clear
command. If the
circuit pack Restart Test (#594) fails, replace the circuit pack.
This error is also caused when the buffers on the board receive data faster
than they can transmit to the endpoints (Receive FIFO Overflow). Use the
above steps to repair the problem.
h. Circuit pack is hyperactive; i.e., it is flooding the switch with messages
sent over the control channel. The circuit pack is taken out-of-service
when a threshold number of these errors is reported to the switch. Clear
the alarm via the following commands:
busyout board UUCSS, reset
board UUCSS, test board UUCSS long clear, release board UUCSS
. if
the error recurs within 10 minutes, then replace the circuit pack.
i. This error indicates that parity errors are detected when transmitting data
to the Packet Bus. Reset the circuit pack via
busyout board UUCSS
and
reset board UUCSS
commands. Also clear the alarm via
test board
UUCSS long clear. If the error returns within 10 minutes, then replace the
circuit pack.
j. This error occurs when the circuit pack detects and error in a received
frame from the packet bus. These errors are most likely caused by a
packet bus problem, but may be due to a circuit pack fault.
Perform a LANHO Receive Parity Error Counter Test (#595) via test board
UUCSS l to determine if the condition has cleared. Also refer to PKT-BUS
Maintenance documentation to determine if the problem is isolated to this
circuit pack or if the problem is caused by Packet Bus faults.
