2. Enter the
test board UUCSS r3
command for this circuit pack. If
this error continues to appear, replace the EI circuit pack.
n. Error Types 3074 and 3075 indicate failures of the Expansion Interface
Circuit Pack Packet Path Test. This packet path test exercises circuitry on
the Expansion Interface circuit pack, the neighbor Expansion Interface or
Switch Node Interface circuit pack, and any intervening DS1 CONV circuit
packs (if the EPN is remoted).
1. Certain packet bus faults can cause these errors without the EI
being defective. Check to see of PKT-BUS errors are also present.
If they are, use the PKT-BUS section of this chapter and
Packet Bus
Fault Isolation and Repair
in Chapter 6 to diagnose the problem.
2. If Error Type 3075 is present without Error Type 3074, replace the
Expansion Interface circuit pack.
3. If Error Type 3074 exists with or without 3075, run
test board
UUCSS
on the EI and follow the repair procedures for any test that
does not pass.
4. If PKT-BUS errors are not present, and replacing the Expansion
Interface does not resolve the problem, there is still the possibility of
a packet bus fault. See
Packet Bus Fault Isolation and Repair
in
Chapter 6.
o. Error Type 3330 indicates a failure of a diagnostic component on the
Expansion Interface circuit pack. The failed component will not impair
service, but it may leave the Expansion Interface circuit pack in a state
where the Expansion Interface circuit pack cannot detect errors.
1. Replace the Expansion Interface circuit pack at a time when it is
most convenient for the customer (this may cause service outages).
p. Error Type 3585 indicates that the Expansion Interface circuit pack
experienced a series of very short out of frame conditions within several
minutes. This may indicate transmission difficulties over the fiber link. If
this condition ceases, the warning alarm should be resolved within 15
minutes.
1. Enter
display errors
and resolve any SNC-BD, TDM-BUS,
TDM-CLK or SYNC errors.
2. Perform the “Fiber Fault Isolation Procedure”
described in Chapter
5.
3. If the alarm is not resolved within the next 15 minutes, replace the
lightwave transceiver on the Expansion Interface circuit pack
reporting the problem and on the connected Expansion Interface
circuit pack, Switch Node Interface circuit pack, or DS1 CONV
circuit pack.
4. If the alarm is not resolved within the next 15 minutes, replace the
Expansion Interface circuit pack reporting the alarm.
