2.7.58 CARLOSS (TRUNK)
Clear the CARLOSS (ML1000, ML100T, MLFX) Alarm
Step 1 Verify that the LAN cable is properly connected and attached to the correct port on the ML-Series card
and on the peer Ethernet port. For more information about fiber connections and terminations, refer to
the “Install Cards and Fiber-Optic Cable” chapter in the Cisco ONS 15454 Procedure Guide.
Step 2 If the alarm does not clear, verify that autonegotiation is set properly on the ML-Series card port and the
peer Ethernet port.
Step 3 If the alarm does not clear, verify that the speed is set properly on the ML-Series card port and the peer
Ethernet port if you are using 10/100 ports.
Step 4 If the alarm does not clear, the Ethernet signal is not valid, but the transmitting device is operational,
replace the LAN cable connecting the transmitting device to the Ethernet port.
Step 5 If the alarm does not clear, disable and reenable the Ethernet port by performing a “shutdown” and then
a “no shutdown” on the Cisco IOS CLI as in the following example:
router(config)# shut
router(config)# no shut
This action restarts autonegotiation.
Step 6 If the alarm does not clear, complete the “Create the Facility Loopback on the Source DS-1, DS-3,
DS3N-12, DS3i-N-12, or EC1 Port” procedure on page 1-10 and test the loopback.
Step 7 If the problem persists with the loopback installed, complete the “Remove and Reinsert (Reseat) Any
Card” procedure on page 2-273.
Step 8 If the alarm does not clear, complete the “Physically Replace a Traffic Card” procedure on page 2-273.
Step 9 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.
