d. Error Type 125A wrong circuit pack is inserted in the slot where this
circuit pack is logically adminis tered. To resolve this problem, either
remove the wrong circuit pac k and insert the logic ally administered c ircuit
pack OR use the change circuit-pack command to readminister this slot
to match the circuit p ack inserted.
e. Error Type 126The port network specifi ed in the PORT field of the error
log entry booted up without a Tone-Clock circuit pack, or with a one that
cannot communicate at all w ith the system. The error is logged five
minutes after the port network is restarted . If no circuit pac k is present,
install one of the proper cod e. If there is a circuit pac k present, replace it.
See the preceding sec tion,
How to Replace the Tone-Clock Circuit Pack .
f. Error Type 257Τhis error indicates transient communication prob lems
with this circuit pac k. This error is not service-affecting and no ac tion is
required.
g. Error Type 513This circuit pac k has an on-board hardware failure.
Replace the circuit p ack using the proc edure describ ed in preced ing
section,
How to Replace the Tone-Clock Circuit Pack .
h. Error Type 769T his error can be ignored, but look for other errors on this
circuit pack.
i. Error Type 1025This error is not service-affecting and no ac tion is
required.
j. Error Type 1538The circuit pack was taken out of servic e because of an
excessive rate of uplink messag es. Use test tone-clock PC long to reset
the circuit pac k and put it bac k into service. If the command is not
successful, replac e the circuit pac k using the proce dure described in the
preceding se c tion,
How to Replace the Tone-Clock Circuit Pack . If the
alarmed circuit p ack is the active Tone-Clock of a dupl icated pair, first
interchange Tone-Clocks via the set tone-clock PC command to avoid a
service outage. If the error occ urs again within 15 minutes, follow normal
escalation proced ures.
k. Error Type 2049 or 2305These errors indicate the loss of one or more
clock signals from the repor ted Tone-Clock circuit pack, whic h was active
at the time of the error. The effect of any of these errors is described in the
table for error type 1. Diagnosis of the p roblem is the same for all four error
types, with the exception noted below.
1. Examine the Hardware Error Log for errors reported ag ainst circuit
packs in the same Port Network, espec ially TDM-CLK, TONE-BD,
DUPINT, SW-CTL, and EXP- INTF. Fo llow t he rep air or rep lac emen t
procedures indic ated for any such errors found .
2. If the error is not corrected by resolving errors found in step 1, the
Tone-Clock circuit pack should b e replaced. See the p receding
section,
How to Replace the Tone-Clock Circuit Pack .
