Chapter 2 Alarm Troubleshooting

2.7.58 EQPT

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. Statement 1057

Note If a circuit shows an incomplete state when the EOC or EOC-L alarm is raised, it occurs when the logical circuit is in place. The circuit is able to carry traffic when the DCC termination issue is resolved. You do not need to delete the circuit when troubleshooting this alarm.

Clear the EOC-L Alarm

Step 1 Complete the “Clear the EOC Alarm” procedure on page 2-49.

Step 2 If the alarm has not cleared, call Cisco TAC (1-800-553-2447).

2.7.58 EQPT

Default Severity: Critical (CR), Service-Affecting (SA)

SONET Logical Object: EQPT

DWDM Logical Object: PPM

An Equipment Failure alarm indicates that a hardware failure has occurred on the reporting card. If the EQPT alarm occurs with a BKUPMEMP alarm, refer to the “BKUPMEMP” alarm on page 2-32. The BKUPMEMP procedure also clears the EQPT alarm.

Clear the EQPT Alarm

Step 1 If traffic is active on the alarmed port, you might need to switch traffic away from it. See the “2.10.1 Protection Switching, Lock Initiation, and Clearing” section on page 2-147for commonly used traffic-switching procedures.

Step 2 Complete the “Soft- or Hard-Reset an Ethernet or Electrical Card in CTC” procedure on page 2-153for the reporting card.

Caution Avoid soft-resetting multiple ONS 15310-MA cards at one time; doing so might cause an unexpected traffic hit.

For the LED behavior, see the “2.9.2 Typical Card LED Activity During Reset” section on page 2-147.

The Cisco ONS 15310-MA is an advanced multi-service platform designed for metropolitan area networks. It facilitates the seamless transport of data, voice, and video over optical networks. One of its main features is its ability to support a variety of interfaces, including Ethernet, SONET/SDH, and Wavelength Division Multiplexing (WDM), allowing users to integrate multiple services into a single platform. Additionally, the ONS 15310-MA supports advanced traffic management and Quality of Service (QoS) features to prioritize critical applications and ensure consistent performance.

The ONS 15310-CL variant is tailored for more specific applications, providing enhanced capabilities aimed at delivering carrier-grade services. It features a robust architecture that accommodates high-capacity traffic without compromising reliability. This model emphasizes low power consumption and a compact design, making it suitable for deployment in space-constrained environments. The ONS 15310-CL also supports a wide range of optical interfaces, making it highly flexible for various network configurations.

In terms of technologies, the Cisco ONS 15310 series leverages Optical Transport Network (OTN) capabilities, providing high efficiency and greater bandwidth utilization. OTN technology enables efficient error correction and adds resilience to the network through its built-in protection mechanisms. Furthermore, the series supports seamless integration with existing IP/MPLS networks, creating a cohesive infrastructure as organizations evolve their networking requirements.

One of the defining characteristics of the ONS 15310 series is its focus on scalability. Network operators can start with a modest deployment and gradually expand capacity as demand grows. This adaptability is complemented by Cisco's comprehensive management and monitoring tools, providing operators with real-time insights into network performance and facilitating proactive management.

In conclusion, the Cisco ONS 15310-MA and ONS 15310-CL models represent sophisticated solutions for modern optical networks. With their versatile features, advanced technologies, and robust design, they empower service providers and enterprises to build resilient, high-capacity networks that meet the demands of today’s data-driven world.
