1.12.3 Lamp Tests for Card LEDs

Symptom Optical (OC-N) ports LEDs do not light, or you are unsure whether the LEDs are working properly.

The LED lamp test determines whether card-level LEDs are operational. For optical ports, this test also causes port-level LEDs to turn on. For Ethernet cards, only card-level LEDs light. For these cards, port-level LEDs can be compared to the given guidelines to determine whether they are working correctly.

Optical port LEDs light during the lamp test. Ethernet cards only illuminate card-level LEDs during the test. Table 1-36describes the possible problem and the solution for optical ports.

Table 1-36 Lamp Test for Optical and Electrical Card LEDs

Possible Problem

Solution

 

 

Faulty optical port LED

A lamp test verifies that all the port LEDs work. Run this diagnostic test as

 

part of the initial system turn-up, a periodic maintenance routine, or any time

 

you question whether an LED is in working order.

 

Complete the “Verify Card LED Operation” procedure on page 1-75.

 

 

Verify Card LED Operation

Step 1 In CTC, click the Maintenance > Diagnostic tabs.

Step 2 Click Lamp Test.

Step 3 Watch to make sure all the port LEDs illuminate as previously noted for several seconds.

Step 4 Click OK on the Lamp Test Run dialog box.

With the exceptions previously described, if an OC-N or DS-N LED does not light up, the LED is faulty. Return the defective card to Cisco through the RMA process. Contact Cisco TAC at http://www.cisco.com/tac or 1-800-553-2447.

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.
