Clear The Eoc-E Alarm - Cisco NCS 2000 series Troubleshooting Manual

Alarm Troubleshooting
Warning
Use of controls, adjustments, or performing procedures other than those specified could result in
hazardous radiation exposure. Statement 1057
Note
If a circuit shows a partial state when this alarm is raised, the logical circuit is in place. The circuit is able to
carry traffic when the connection issue is resolved. You do not need to delete the circuit when troubleshooting
this alarm.
Note The EOC alarm is raised on the DWDM trunk in MSTP systems. Its SDH (ETSI) counterpart, MS-EOC, is
not raised against the trunk port.

12. Recreate the SDCC termination.
13. Verify that both ends of the DCC have been recreated at the optical ports.
If the LOS (DS1) alarm or SF-L alarm is reported, complete the appropriate troubleshooting procedure
in the "Alarm Troubleshooting" chapter of the troubleshooting guide.
If the alarm does not clear on the reporting node, verify the physical connections between the cards and
that the fiber-optic cables are configured to carry SDCC traffic.
If the physical connections are correct and configured to carry DCC traffic, ensure that both ends of the
fiber span have in-service (IS) ports. Verify that the ACT/SBY LED on each card is green.
When the LEDs on the cards are correctly illuminated, complete the "Verify or Create Node Section
DCC Terminations" procedure to verify that the DCC is provisioned for the ports at both ends of the
fiber span.
Repeat Step 4 procedure at the adjacent nodes.
If DCC is provisioned for the ends of the span, verify that the port is active and in service by completing
the following steps:
For all nodes, if the card is in service, use an optical test set to determine whether signal failures are
present on fiber terminations. For specific procedures to use the test set equipment, consult the
manufacturer.
If no signal failures exist on terminations, measure power levels to verify that the budget loss is within
the parameters of the receiver. Refer to the Configuration guide for card power levels.
If budget loss is within parameters, ensure that fiber connectors are securely fastened and properly
terminated.
If fiber connectors are properly fastened and terminated, complete the "Reset an Active Control Card
and Activate the Standby Card" procedure.
If the control card reset does not clear the alarm, delete the problematic SDCC termination:
