TONE-BD (Tone-Clock Circuit Pack)
Issue 1 May 2002
8-1181555-233-142
Notes:
a. Error Type 1
This error indicates the circuit pack totally stopped
functioning or it was physically removed from the system.
NOTE:
The alarm is logged approximately 11 minutes after the circuit pack is
removed/SAKI Sanity test (#53) fails.
If the circuit pack is not present in the system, insert a circuit pack in the
slot indicated by the error to resolve the error.
If the circuit pack is present in the system, it is faulty and must be replaced.
See the preceding section, ‘‘Replacing the IPSI Circuit Pack’’.
Further effects of this error depend on the system’s reliability option.
.
b. Error Type 23 The circuit pack has been logically administered but not
physically installed. Installing the circuit pack will resolve the alarm.
c. Error Type 125
A wrong circuit pack is inserted in the slot where this
circuit pack is logically administered. To resolve this problem, either:
1. Remove the wrong circuit pack, and insert the logically administered
circuit pack.
or
Use the change circuit-pack command to re-administer this slot to
match the circuit pack inserted.
d. Error Type 126
The port network specified in the PORT field of the error
log entry booted up without a Tone-Clock circuit, or with a one that cannot
communicate at all with the system. The error is logged five minutes after
the port network is restarted. If no circuit pack is present, install one of the
proper code. If there is a circuit pack present, replace it. See ‘‘Replacing
the IPSI Circuit Pack’’.
e. Error Type 257
Τhis error indicates transient communication problems
with this circuit pack. This error is not service-affecting and no action is
required.
f. Error Type 513
This circuit pack has an on-board hardware failure.
Replace the circuit pack using the procedure described in ‘‘Replacing the
IPSI Circuit Pack’’.
