PKT-INT (Packet Interface)
Issue 1 May 2002
8-935555-233-142
j. Error 1793 indicates a FLASH Memory test failure. The Packet Interface
circuit may still be operational if no other errors are reported. However the
circuit may report a fatal fault during board initialization. This may occur
during a system recovery level more severe than a WARM restart. For
more information, refer to the repair procedures of Test #884.
k. Error 2049 indicates a LAP-D Received Buffer Overflow error. The Packet
Interface circuit‘s packet-bus receive buffer overflowed. For more
information, refer to the repair procedures of Test #887.
l. Error 2305 indicates a parity failure detected by the packet-bus interface.
The Packet Interface circuit received packets with parity errors from the
packet bus.
1. Check for errors logged against the packet bus and Maintenance/
Test circuit pack. Refer to the appropriate repair procedures to clear
those errors first.
2. Check every other circuit pack connected to the packet bus in the
same cabinet. Packet-bus failures are likely to be caused by a faulty
circuit pack connected to the backplane or bent pins on the back
plane.
3. If steps 1 and 2 above do not clear the problem, execute the test
packet-interface command, and follow repair procedures described
for Test #887.
m. Error 2561 indicates a Active-Standby Peer Link test failure indicating a
possible failure of either the:
■ Active IPSI’s Packet Interface circuit
■ Standby IPSI’s Packet Interface circuit
If the number of errors exceeds a defined threshold, a Minor alarm is
raised. For more information, refer to the repair procedures of Test #888.
n. Error 2817 indicates a Standby Packet Interface circuit Translation RAM
failure. A MINOR alarm is raised when there are 1 to 5 bad locations and a
MAJOR alarm is raised when there are 5 or more bad locations. Execute
the test packet-interface command, and follow repair procedures
described for Test #887.
