g. Error Type 76 — This error can be ignored, but look for other errors on this
circuit pack.
h. Error Type 1025 — This error is not service-affecting and no action is
required.
i. Error Type 1538 — The circuit pack was taken out of service because of
an excessive rate of uplink messages. Use test tone-clock PC long to
reset the circuit pack and put it back into service. If the command is not
successful, replace the circuit pack using the procedure described in

Circuit Pack''.
NOTE:
Replacing the circuit pack and retesting it with the test
tone-clock command is not adequate to retire this alarm and
return the IPSI circuit pack to full service; the Clock Health
Inquiry test (#46) will continue to fail. Because the ability to
generate clocks was considered lost, once any repairs have
been made it is necessary to execute the set tone-clock PC
override command, forcing the circuit pack to become active.
If the problem has not actually been corrected, this action may
cause a disruption in service for active digital facilities users.

board were lost.
