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.
Clear the EOC Alarm
Step 1 If the “LOS (OCN)” alarm on page 1-99 is also reported, complete the “Clear the LOS (OCN) Alarm”
procedure on page 1-100 .
Step 2
If the “SF-L” condition on page 1-127 is reported, complete the “Clear the SF-L Condition” procedure
on page 1-127 .
Step 3 If the alarm does not clear on the reporting node, ensure that the physical connections between the ports
and that the fiber-optic cables are configured to carry SDCC traffic. If they are not, correct them. For
more information about fiber connections and terminations, refer to the “Install Hardware” chapter in
the
Cisco ONS 15310-CL and Cisco ONS 15310-MA Procedure Guide .
Caution
Always use the supplied electrostatic discharge wristband when working with a powered ONS 15310-CL
or ONS 15310-MA.
If the physical connections are correct and configured to carry DCC traffic, verify that both ends of the
fiber span have in-service (IS-NR) ports. Verify that the ACT LED is green.
Step 4 When the LED on the controller card (15310-CL-CTX or CTX2500) is green, complete the “Verify or
Create Node DCC Terminations” procedure on page 1-156 to ensure that the DCC is provisioned for the
ports at both ends of the fiber span.
Step 5
Repeat Step 4 at the adjacent nodes.
Step 6
If DCC is provisioned for the ends of the span, verify that the port is active and in service by completing
the following steps:
a.
In node view, double-click the 15310-CL-CTX or CTX2500 to display the card view.
b. Click the Provisioning > Optical > Line tabs.
c.
Confirm that the OC-3 or OC-12 port shows a green LED.
A green ACT LED indicates an active card.
d.
Verify that the Admin State column lists the port as IS .
e.
If the Admin State column lists the port as OOS,MT or OOS,DSBLD, click the column and click IS
from the drop-down list. Click Apply .
Note If ports managed into IS administrative state are not receiving signals, the LOS alarm is
either raised or remains, and the port service state transitions to OOS-AU,FLT.
