5. Execute the test tone-clock PC command where P is the port network
which contains the Expansion Interface circuit pack’s neighbor
Expansion Interface on the OPPOSITE end of the fiber and C refers to
the carrier which contains the Active Tone-Clock on port network P.
Also, look for SYNC errors in the Error Log. If there are any tests failing
or errors found, resolve these problems and then rerun Test #238. If the
test still fails and the system has a Standby Tone-Clock, switch the
Active Tone-Clock on this network (set tone-clock PC command,
where P is the port network containing the Expansion Interface circuit
pack on the OPPOSITE end of the fiber and C is the carrier containing
the Standby Tone-Clock). Also, if the EPN is down, replace the EPN
Tone-Clock circuit pack in carrier A of the EPN.
6. Check for errors using the display errors command with the Category
field set to "tone" and the Active alarms field set to "n." Some of the
alarms on EPN objects might have been resolved if the EPN went
down. Refer to the documentation for descriptions of any of the error
types occurring at about same time as the EXP-LINK error types.
Resolve any active alarms. Also, if Error Type 18 was logged against
the SYNC MO when the EPN went down, the problem was probably
that the Synchronization on-line reference became invalid. Since,
reference switching was disabled, the Tone-Clock did not switch away
from the invalid reference. Therefore, the Tone-Clock put out an
"out-of-spec" system clock. Execute the enable
synchronization-switch command. If the EPN is down, reseat the
Tone-Clock circuit packs on the EPN. This action should restore the
EPN to service.
7. Follow the procedure described in "Relationship Between Expansion
Interface and Tone-Clock Circuit Packs" near the beginning of this
section if the symptoms match those described there.
PASS The Expansion Interface circuit pack has detected the valid framing signal
on the fiber.
1. Refer to errors from other Expansion Interface circuit pack tests if the
link is still not functioning.
0NO
BOARD
No board was detected by the test.
1. Check the error log for wrong board (error 125) or no board (error 131).
Resolve either of these issues, if applicable.
2. Check that the board is properly translated and inserted. If so, check
for hyperactivity (error 1538). If hyperactive, use the reset board PCSS
command.
3. Run the test again. If it fails, the ID chip on board may be bad. Replace
the board and retest.
