For information about this alarm or condition, refer to the "Alarm Troubleshooting" chapter in the
Cisco ONS 15454 DWDM Troubleshooting Guide. This guide discusses all DWDM alarms.
2.7.316 PDI-P
PDI-P is a set of application-specific codes indicating a signal label mismatch failure (SLMF) in the
ONS 15454 STS path overhead. The condition indicates to downstream equipment that there is a defect
in one or more of the directly mapped payloads contained in that STS synchronous payload envelope
(SPE). For example, the mismatch could occur in the overhead to the path selector in a downstream node
configured as part of a path protection. The PDI-P codes appear in the STS Signal Label (C2 byte).
An SLMF often occurs when the payload (for example, ATM) does not match what the signal label is
reporting. The
only condition reported with the AIS, clearing PDI-P clears the AIS. PDI-P can also occur during an
upgrade, but usually clears itself and is not a valid condition.
A PDI-P condition reported on an OC-N port supporting a G1000-4 card circuit could result from the
end-to-end Ethernet link integrity feature of the G1000-4 card. If the link integrity is the cause of the
path defect, it is typically accompanied by the
"CARLOSS (G1000)" alarm on page 2-62
circuit. If this is the case, clear the TPTFAIL and CARLOSS alarms to resolve the PDI-P condition.
A PDI-P condition reported on an OC-N port supporting an ML-Series card circuit could result from the
end-to-end Ethernet link integrity feature of the ML-Series card. If the link integrity is the cause, it is
typically accompanied by the
against one or both POS ports terminating the circuit. If TPTFAIL is reported against one or both of the
POS ports, troubleshooting the accompanying alarm clears the PDI-P condition. Refer to the
Cisco ONS 15454 and Cisco ONS 15454 SDH Ethernet Card Software Feature and Configuration
Guide for more information about ML-Series cards.
On the OC-192 card, the laser is on when the card is booted and the safety key is in the on position
Warning
(labeled 1). The port does not have to be in service for the laser to be on. The laser is off when the
safety key is off (labeled 0). Statement 293
Invisible laser radiation could be emitted from the end of the unterminated fiber cable or connector.
Warning
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
