Chapter 2 Alarm Troubleshooting

Alarm Procedures

The Open Slot condition indicates that there is an open slot in the system shelf. Slot covers assist with

airflow and cooling.

Clear the OPEN-SLOT Condition

Step 1 To install a slot cover and clear this condition, refer to the procedures located in the “Install Hardware”

chapter of the Cisco ONS 15310-CL and Cisco ONS 15310-MA Procedure Guide.

Step 2 If the condition 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).

2.7.188 PDI-P

Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)

SONET Logical Objects: STSMON, STSTRM

A PDI-P is a set of application-specific codes indicating a signal label mismatch failure (SLMF) in the

ONS 15310-CL or ONS 15310-MA STS path overhead. The condition indicates to downstream

equipment that a defect is present 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 UPSR. The PDI-P codes appear in the STS Signal

Label (C2 byte).

An SLMF often occurs when the payload does not match what the signal label is reporting. The “AIS”

condition on page 2-20 often accompanies a PDI-P condition. If the PDI-P is 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-3 or OC-12 port supporting an ONS 15310-CL or ONS 15310-MA

Ethernet card circuit could result from the end-to-end Ethernet link integrity feature of the Ethernet card.

If the link integrity is the cause of the path defect, it is typically accompanied by the “CARLOSS

(EQPT)” alarm on page 2-39 reported against one or both Ethernet ports terminating the circuit. If this

is the case, clear the TPTFAIL and CARLOSS alarms to resolve the PDI-P condition.

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

Warning

Use of controls, adjustments, or performing procedures other than those specified could result in

hazardous radiation exposure.
