Clear the TPTFAIL (CE100T) Alarm
Step 1 Clear any alarms being reported by the OC-N port on the CE100T-8 circuit.
Step 2 If no alarms are reported by the OC-N port, or if the “PDI-P” condition on page 2-113 is reported, the
problem could be on the far-end G-Series Ethernet port. Clear any alarms, such as CARLOSS, reported
against the far-end port or card.
Step 3 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.
