Chapter 2 Alarm Troubleshooting
2.7.52 CARLOSS (EQPT)
A Carrier Loss on the LAN Equipment alarm generally occurs on OC-N cards when the ONS 15454 and
the workstation hosting CTC do not have a TCP/IP connection. The problem involves the LAN or data
circuit used by the RJ-45 (LAN) connector on the TCC2/TCC2P or the LAN backplane pin connection.
This CARLOSS alarm does not involve an Ethernet circuit connected to an Ethernet port. The problem
is in the connection and not CTC or the node.
On TXP_MR_10G, TXP_MR_2.5G, TXPP_MR_2.5G or MXP_2.5G_10G cards, CARLOSS is also
raised against trunk ports when ITU-T G.709 monitoring is turned off.
A TXP_MR_2.5G card can raise a CARLOSS alarm when the payload is incorrectly configured for the
10 Gigabit Ethernet or 1 Gigabit Ethernet payload data types.
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
Use of controls, adjustments, or performing procedures other than those specified could result in

hazardous radiation exposure. Statement 1057
For more information about provisioning MXP or TXP PPMs, refer to the "Provision Transponders and
Note
Muxponders" chapter of the Cisco ONS 15454 DWDM Procedure Guide. For more information about
the cards themselves, refer to the Cisco ONS 15454 DWDM Reference Manual. For more information
about MRC-12, MRC-4, and OC192-XFP/STM64-XFP cards, refer to the "Optical Cards" chapter in the
Cisco ONS 15454 Reference Manual. For more information about Ethernet cards, refer to the "Ethernet
Cards" chapter in the Cisco ONS 15454 Reference Manual.
Clear the CARLOSS (EQPT) Alarm
If the reporting card is an MXP or TXP card in an ONS 15454 node, verify the data rate configured on
Step 1
the pluggable port module (PPM):
a.
b.
c.
d.
Step 2 If the reporting card is an OC-N card, verify connectivity by pinging the ONS 15454 that is reporting
the alarm by completing the

Default Severity: Major (MJ), Service-Affecting (SA)
SONET Logical Object: EQPT
Double-click the reporting MXP or TXP card.
Click the Provisioning > Pluggable Port Modules tabs.
View the Pluggable Port Modules area port listing in the Actual Equipment Type column and
compare this with the contents of the Selected PPM area Rate column for the MXP or TXP multirate
port.
If the rate does not match the actual equipment, you must delete and recreate the selected PPM.
Select the PPM, click Delete, then click Create and choose the correct rate for the port rate.
