EXP-INTF (Expansion Interface Circuit Pack)
Issue 1 May 2002
8-783
555-233-143
Another way to resolve or prevent this alarm is to use the change circuit
pack command to remove the EI circuit pack administrative entry for this
slot after the EI circuit pack has been removed from the slot.
It is also possible that the EI could be held in reset by the PN’s
Maintenance board (MAINT) and is not inserted in the system. Try issuing
the test maint P long command on the Maintenance board in the same
PN.
e. Error Type 257—Indicates that this EI circuit pack is detecting incorrect
data on the incoming fiber bit stream. The data is originating at the
connected circuit pack (DS1 CONV circuit pack, EI circuit pack, or SNI
circuit pack).
1. Enter display errors and save a copy of the error log for use in later
steps. Intervening repair procedures are likely to alter the contents
of the error log and this information may be needed in later steps.
2. Perform the
‘‘Fault Isolation for Fiber Links’’ on page 4-19
3. If errors are still present or if this error occurs intermittently, replace
the EI circuit packs, SNI circuit packs, DS1 CONV circuit packs, or
the transceivers on this link.
4. These errors could result from a bad timing reference on the
network or switch node that contains the DS1 CONV circuit pack,
the EI circuit pack or SNI circuit pack on the opposite end of the
fiber. Refer to the error log that was saved in step 1 and follow the
associated repair procedure for EXP-INTF error 2305 to resolve this
error. If there are any TONE-BD, TDM-CLK, or SYNC errors,
resolve these errors as well.
f. Error Type 513 with Aux Data 5–7— Indicates an ON BOARD hardware
failure of the circuit packs RAM or ROM.
1. Replace the EI circuit pack.
g. Besides running the test sequence and following procedures outlined for
Test #238, perform the
‘‘Fault Isolation for Fiber Links’’ on page 4-19
Chapter 5.
h. Error type 1281—The link to the neighbor circuit pack is broken or that the
fibers have been connected incorrectly. Enter test board UUCSS and
follow repair procedures for the tests.
i. Error Type 1538—Indicates a hyperactive EI circuit pack that is generating
an abnormal amount of control messages to the Processor. When this
error was generated, the EI was automatically reset by the system. If this
system does not have duplicated Port Network Connectivity, service to the
PN will have been disrupted. If this system does have duplicated Port
Network Connectivity, the system should have switched to the standby Port
Network Connectivity.
1. Enter the reset board UUCSS command for this EI circuit pack.
2. If error 1538 is detected again, replace the EI circuit pack.
