e. Determine whether the two Ethernet circuits on each side of the Ethernet manual cross-connect have
the same circuit size from the circuit size information you recorded.
f. If one of the circuit sizes is incorrect, complete the “Delete a Circuit” procedure on page 2-275 and
reconfigure the circuit with the correct circuit size. Refer to the “Create Circuits and VT Tunnels”
chapter in the Cisco ONS 15454 Procedure Guide for detailed procedures to create circuits.
Step 13 If a valid Ethernet signal is present, complete the “Remove and Reinsert (Reseat) Any Card” procedure
on page 2-273.
Step 14 If the alarm does not clear, complete the “Physically Replace a Traffic Card” procedure on page 2-273
for the Ethernet card.
Step 15 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport
for more information or call Cisco TAC 1 800 553-2447 in order to report a Service-Affecting (SA)
problem.

Default Severity: Major (MJ), Service-Affecting (SA)
SONET Logical Objects: ML1000, ML100T, MLFX
A Carrier Loss alarm on an ML-Series Ethernet card is the data equivalent of the “LOS (OCN)” alarm
on page 2-164. The Ethernet port has lost its link and is not receiving a valid signal.
A CARLOSS alarm occurs when the Ethernet port has been configured from the Cisco IOS command
line interface (CLI) as a no-shutdown port and one of the following problems also occurs:
• The cable is not properly connected to the near or far port.
• Autonegotiation is failing (which raises the “AUTONEG-RFI” alarm on page 2-50).
• The speed (10/100 ports only) is set incorrectly.
Note For information about provisioning ML-Series Ethernet cards from the Cisco IOS interface, refer to the
Cisco ONS 15454 and Cisco ONS 15454 SDH Ethernet Card Software Feature and Configuration
Guide.
