Chapter 1 General Troubleshooting - Cisco ONS 15310-CL Troubleshooting Manual

General Troubleshooting
The terms "Unidirectional Path Switched Ring" and "UPSR" may appear in Cisco literature. These terms
Note
do not refer to using Cisco ONS 15xxx products in a unidirectional path switched ring configuration.
Rather, these terms, as well as "Path Protected Mesh Network" and "PPMN," refer generally to Cisco's
path protection feature, which may be used in any topological network configuration. Cisco does not
recommend using its path protection feature in any particular topological network configuration.
This chapter provides procedures for troubleshooting the most common problems encountered when
operating a Cisco ONS 15310-CL or Cisco ONS 15310-MA. To troubleshoot specific alarms, see
Chapter 1, "Alarm Troubleshooting."
1.1 Network Troubleshooting
•
to test circuit paths through the network or logically isolate faults.
Note
1.2 Identify Points of Failure on an Electrical Circuit
•
hairpin tests, which you can use to test ONS 15310-CL DS-N circuit paths through the network or
logically isolate faults.
1.3 Identify Points of Failure on an OC-N Circuit
•
hairpin tests on OC-N paths, which you can use to test ONS 15310-CL or ONS 15310-MA OC-N
circuit paths through the network or logically isolate faults.
1.4 Troubleshooting Wideband Electrical Card(WBE-28 and WBE-84 Cards) FEAC on DS3 Ports
•
1.5 Troubleshooting WBE-28 and WBE-84 Cards with Far End Loopcodes on DS1 Ports
•
1.6 Troubleshooting Ethernet Circuit Paths With
•
tests for CE100T-8 ports (and intermediate node OC-N ports the Ethernet circuit is mapped
through). Follow these instructions to test an Ethernet circuit through the network or logically
isolate faults.
The remaining sections describe symptoms, problems, and solutions that are categorized according to
the following topics:
1.7 Restore the Database and Default
•
the node to the default setup.
1.8 PC Connectivity
•
network connectivity to the ONS 15310-CL or ONS 15310-MA.
