d. This alarm is raised after an Expansion Interface circuit pack has been
removed from a slot for 5 minutes. The alarm will be resolved when the
Expansion Interface circuit pack is physically inserted into this slot and
becomes recognized by software.
Another way to resolve or prevent this alarm is to use the
change circuit
pack
command to remove the Expansion Interface circuit pack
administrative entry for this slot after the Expansion Interface circuit pack
has been removed from the slot.
It is also possible that the EI could be held in reset by the EPN
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
port network.
e. Error Type 257 indicates that this Expansion Interface 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,
Expansion Interface circuit pack, or Switch Node Interface 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 “Fiber Fault Isolation Procedure” described in Chapter
5.
3. If errors are still present or if this error occurs intermittently, replace
the Expansion Interface circuit packs, Switch Node Interface 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 which contains the DS1 CONV circuit pack,
the Expansion Interface circuit pack or Switch Node Interface
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 Expansion Interface circuit pack.
g. Besides running the test sequence and following procedures outlined for
test #238, perform the “Fiber Fault Isolation Procedure” described in
Chapter 5.
h. Error type 1281 means that 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 Expansion Interface circuit pack
that is generating an abnormal amount of control messages to the
Processor. When this error was generated, the Expansion Interface was
automatically reset by the system. If this system does not have duplicated
