2.6.143 RFI-P
•Not Reported (NR), Non-Service Affecting (NSA)
An RFI Path condition occurs when the ONS15327 detects an RFI in the SONET overhead because of
a fault in another node. Resolving the fault in the adjoining node clears the RFI-P condition in the
reporting node. RFI-P occurs in the node that terminates a path.
Procedure: Clear the RFI-P Condition
Step 1 Verify that the ports are enabled and in service (IS) on the reporting ONS 15327:
a. Confirm that the OC-N card shows a green LED in CTC or on the physical card.
A green LED indicates an active card. An amber LED indicates a standby card.
b. To determine whether the OC-N port is in service, double-click the card in CTC to display the card
view.
c. Click the Provisioning > Line tabs.
d. Verify that the State column lists the port as in service (IS).
e. If the State column lists the port as OOS, click the column and choose IS. Click Apply.
Step 2 To find the path and node failure, verify the integrity of the SONET STS circuit path at each of the
intermediate SONET nodes.
Step 3 Clear alarms in the node with the failure, especially an UNEQ-P alarm (see page 2-122) or an UNEQ-V
alarm (see page 2-123).
Step 4 If the condition does not clear, log onto http://www.cisco.com/tac for more information or call TAC
(1-800-553-2447).
2.6.144 RFI-V
•Not Reported (NR), Non-Service Affecting (NSA)
An RFI VT Layer condition occurs when the ONS15327detects an RFI in the SONET overhead because
of a fault in another node. Resolving the fault in the adjoining node clears the RFI-V condition in the
reporting node. RFI-V indicates that an upstream failure has occurred at the VT layer.
Warning Invisible laser radiation might 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 might pose an eye hazard. Use of controls or adjustments or performance of procedures other than
those specified might result in hazardous radiation exposure.
