h. A critical hardware failure has been detected on the circuit pack. Reset the
circuit pack via the busyout board PCSS and reset board PCSS
commands. If the Circuit Pack Restart Test (#594) passes, then the
on-board circuitry is healthy. Retire the alarm via the test board PCSS
long clear command. If the Circuit Pack Restart Test (#594) fails, replace
the circuit pack.
The reported error types correspond to the following detected errors:
i. These error types are reported when the following errors are detected:
j. These errors indicate that the circuit pack is having problems transmitting
data to the Packet Bus.
1293
On-board auxiliary processor insane
1294
Internal memory access error
1537
Frame overrun at Packet Bus interface. This condition may be
caused by an on-board fault or by faulty data received on one of the
circuit pack’s external ports. If any of the ports on this circuit pack are
alarmed, refer to the repair procedures for those maintenance
objects.
1538
Circuit packet is hyperactive; that is, 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 PCSS, reset board PCSS, test board PCSS long clear,
release board PCSS. If the error recurs within 10 minutes, then
replace the circuit pack.
1793
Parity errors are detected when transmitting data to the Packet Bus.
1794
Overflow of Packet Bus transmit buffers has occurred.
1795
Circuit pack cannot find end of frame when transmitting to Packet
Bus. Clear the alarm via the following commands: busyout board
PCSS, reset board PCSS, test board PCSS long clear, release
board PCSS. If the error recurs within 10 minutes, then replace the
circuit pack.
2306
This error occurs when the circuit pack detects an 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.An invalid
Link Access Procedure Data (LAPD) frame error occurs if the frame
contains a bad Cyclical Redundancy Checking (CRC), is greater than
the maximum length, or violates the link level protocol.When bus
parity errors are reported, the LANBIC Receive Parity Error Counter
Test (#595) should be performed to determine if the condition had
cleared. Refer to the “PKT-BUS (Packet Bus)” Maintenance
documentation to determine if the problem is isolated to this circuit
pack or if the problem is caused by Packet Bus faults.
