Read and Clear Board Counters (#887)
This test involves sending commands to read on-circuit pack error counters on
the Packet Interface circuit pack. It also verifies the message interface between
the SPE and the Packet Interface circuit pack.
This test checks different circuit pack counters depending on whether the circuit
pack is on the active or standby SPE.
If the Packet Interface circuit pack is on the active SPE, this test reads and clears
the Parity Error counter and FIFO Overflow counter. Those counters are not used
when a Packet Interface circuit pack is in standby mode.
If the Packet Interface circuit pack is on the standby SPE, this test reads but does
not clear a Translation RAM counter. The Translation RAM counter is not cleared
1-3 FAIL The test failed. Maintenance was unable to establish a looparound link from
the Packet Interface circuit pack back to itself or was unable to receive data
that was sent out over one side of the looparound link.
1. Issue the test packet-interface CS command to retry the test. If the same
error code is observed, background maintenance software will
automatically attempt to reset the circuit pack and clear the problem.
2. Retry the command and if the test fails, replace the circuit pack.
3. If the test continues to fail after replacing the circuit pack, run the test
packet P long command. If any of the tests fail, the fault may be on the
Packet Bus. Refer to the PKT-BUS (Packet Bus) Maintenance
documentation for recommended repair procedures.
4. If the test continues to fail after the circuit pack is replaced and with no
other alarms associated with the Packet Bus or circuit packs connected to
the Packet Bus, follow normal escalation procedures.
PASS This test passed. The circuit pack and its interface with the SPE are
functioning properly. If the system is unable to place calls on cabinets other
than the SPE cabinet, then:
1. Check for errors on the Packet Bus and Maintenance/Test circuit pack.
Solve those errors first.
2. Check all other circuit packs 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. Check the Packet Interface circuit pack connections to the Packet Bus.
