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

Alarm Troubleshooting
Warning
The laser is on when the card is booted and the safety key is in the on position (labeled 1). The port does
not have to be in service for the laser to be on. The laser is off when the safety key is off (labeled 0).
Statement 293
Warning
Invisible laser radiation could be emitted from the end of the unterminated fiber cable or connector.
Do not stare into the beam directly with optical instruments. Viewing the laser output with certain
optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm
could pose an eye hazard. Statement 1056
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 an incomplete 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.

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 RS-DCC traffic. If they are not, correct them. For
more information about OC-N fiber connections and terminations, refer to the Install Cards and
Fiber-Optic Cable chapter in the Configuration guide.
When the LEDs on the cards are correctly illuminated, complete the
Terminations, on page 456 procedure to verify that the DCC is provisioned for the ports at both ends of
the fiber span.
Repeat Step 2, on page 382
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.
If budget loss is within parameters, ensure that fiber connectors are securely fastened and properly
terminated. For more information refer to Install Cards and Fiber-Optic Cables chapter in the
Configuration guide.
