Chapter 2 Alarm Troubleshooting

2.7.175 MEM-GONE

2.7.175 MEM-GONE

Default Severity: Major (MJ), Non-Service-Affecting (NSA)

SONET Logical Object: EQPT

The Memory Gone alarm occurs when data generated by software operations exceeds the memory capacity of the 15310-CL-CTX or CTX2500 card. CTC does not function properly until the alarm clears. The alarm clears when additional memory becomes available.

The alarm does not require user intervention. 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).

2.7.176 MEM-LOW

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

SONET Logical Object: EQPT

The Free Memory of Card Almost Gone alarm occurs when data generated by software operations is close to exceeding the memory capacity of the 15310-CL-CTX or CTX2500 card. The alarm clears when additional memory becomes available. If additional memory is not made available and the memory capacity of the card is exceeded, CTC ceases to function.

Note The alarm does not require user intervention. 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).

2.7.177 MFGMEM

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

SONET Logical Objects: BPLANE, FAN, PPM

The Manufacturing Data Memory Failure alarm occurs when the electronically erasable programmable read-only memory (EEPROM) fails on a card or component, or when the 15310-CL-CTX or CTX2500 card cannot read this memory. EEPROM stores manufacturing data that a 15310-CL-CTX card uses to determine system compatibility and shelf inventory status. Unavailability of this information can cause less-significant problems.

To clear the MFGMEM alarm, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1-800-553-2447) to report a Service-Affecting (SA) problem.

2.7.178 NO-CONFIG

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

SONET Logical Object: EQPT

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.
