d. This alarm is raised after an EI circuit pack has been removed from a slot
for 11 minutes. The alarm is resolved when the EI circuit pack is inserted
into this slot. 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. Or, if the circuit pack is in the system and the red LED is on,
then follow the instructions for "Red (alarm)" in the "Control and Port Circuit
Pack Status LEDs" section in Chapter 7, "LED Interpretation".
e. Error Type 257 with Aux Data 85 through 88 indicates that this EI circuit
pack is detecting incorrect data on the incoming fiber bit stream. The data
is originating at the opposite EI circuit pack. These errors could result from
a bad timing reference on the network which contains the EI circuit pack
on the opposite end of the fiber. For example, if the error is logged against
the 1B01 (PPN) EI circuit pack, then the bad timing reference is on the
EPN. Resolve any EXP-INTF errors 2305, 769, or 770. Resolve any
TONE-BD, TDM-CLK, or SYNC errors. Finally, if the errors continue to
occur, perform the following procedure:
1. If the EI circuit pack reporting the error is part of the Active link and
a Standby link exists, switch to the Standby link.
2. Reset the EI circuit pack at the opposite end of fiber.
3. Issue the test board PCSS repeat 10 command, where PCSS is
the address of the EXP-INTF circuit pack reporting the error. If
Tests #241 or #316 fail even once, follow the procedures
associated with the failures.
4. Wait 15 minutes. Then check the Error Log to see if new errors of
type 257 have been detected.
5. If errors are present, reset the EI circuit pack reporting the errors.
6. Wait five minutes. Then check the Error Log to see if new errors of
type 257 have been detected.
7. If errors are present, replace the EI circuit pack or transceiver at the
opposite end of the fiber.
8. Wait 15 minutes. Then check the Error Log to see if new errors of
type 257 have been detected.
9. If errors are present or if this error occurs intermittently (over one
week’s time), replace the EI circuit packs or transceivers on this
link.
f. Error Type 513 with Aux Data 5 through 7 indicates an ON BOARD
hardware failure of the circuit packs RAM or ROM. Replace the EI circuit
pack or transceiver.
g. Error Type 1538 indicates a hyperactive EI circuit pack that is generating
an abnormal amount of control messages to the Processor circuit pack.
When this error was generated, the EI was automatically reset by the
system. If this system does not have duplicate EI Links, service to the EPN
