Chapter 2 Alarm Troubleshooting

2.7.42 CONTBUS-DISABLED

Clear the CONTBUS-CLK-B Alarm

Step 1 If a single traffic port is reporting the alarm and it is part of a path protection, complete the “Initiate a Force Switch for All Circuits on a Path Protection Span” procedure on page 2-151. If the traffic port is part of a 1+1 protection group, complete the “Clear a 1+1 Force or Manual Switch Command” procedure on page 2-149.

Note If the active CTX2500 card is reporting the alarm, shelf control should already have switched off the card.

Step 2 Complete the appropriate procedure in the “2.10.3 Physical Card Reseating and Replacement” section on page 2-154for the reporting card.

Step 3 If the alarm 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).

Step 4 If traffic was manually switched in a 1+1 protection group, revert traffic to the original port by completing the “Clear a 1+1 Force or Manual Switch Command” procedure on page 2-149. If traffic was manually switched in a path protection, revert traffic to the original path by completing the “Clear an External Switching Command on a Path Protection Span” procedure on page 2-152.

2.7.42 CONTBUS-DISABLED

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

SONET Logical Object: EQPT

The CONTBUS-DISABLED alarm occurs when an Ethernet card is defective upon insertion into the chassis or when a card that is already present in the chassis becomes defective. (That is, the card fails the enhanced cell bus verification test.) The alarm persists as long as the defective card remains in the chassis. When the card is removed, CONTBUS-DISABLED will remain raised for a one-minute wait time. This wait time is designed as a guard period so that the system can distinguish this outage from a briefer card reset communication outage.

If no card is reinserted into the original slot during the wait time, the alarm clears. After this time, a different, nondefective card (not the original card) should be inserted.

When CONTBUS-DISABLED is raised, no message-oriented communication is allowed to or from this Ethernet slot to the controller card (15310-CL-CTX or CTX2500 card), thus avoiding node communication failure.

Caution CONTBUS-DISABLED clears only when the faulty card is removed for one minute. If any card at all is reinserted before the one-minute guard period expires, the alarm does not clear.

CONTBUS-DISABLED overrides the IMPROPRMVL alarm during the one-minute wait period, but afterward IMPROPRMVL can be raised because it is no longer suppressed. IMPROPRMVL is raised after CONTBUS-DISABLED clears if the card is in the node database. If CONTBUS-DISABLED has cleared but IMPROPRMVL is still active, inserting a card will clear the IMPROPRMVL alarm.

ONS 15310-CL, ONS 15310-MA specifications

Cisco Systems has long been a leader in networking and telecommunications technology, and among its impressive lineup of products, the Cisco ONS 15310 series stands out as an essential solution for optical networking. This series includes models such as the ONS 15310-MA, ONS 15310-CL, and ONS 15310-CA, each designed to meet the diverse needs of service providers and enterprises seeking to enhance their optical transport networks.

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.
