Product Review

The Cisco 20-1GE-FLEX module, designed for compatibility with all Cisco CRS-1 Systems and supporting Cisco IOS XR Software Release 3.8.1 or later, offers a significant advantage in terms of system integration and software support. With 20 1GE ports, it provides ample connectivity options for high-density networking requirements, yet its reliance on SFP physical interfaces might limit flexibility compared to solutions supporting newer interface standards. Additionally, while the module's support for online insertion and removal and its field-replaceable feature enhance maintenance efficiency, its operational temperature range and power consumption could pose challenges in environments with extreme temperatures or limited power availability.


The Cisco 20-1GE-FLEX module offers a high-density, 1 Gigabit Ethernet interface solution, designed to integrate seamlessly with Cisco CRS-1 systems. This module features twenty 1 Gigabit Ethernet ports, enabling efficient connectivity and high-speed data transfer rates for a wide range of network architectures. The module is compatible with Cisco IOS XR Software Release 3.8.1 or later, ensuring advanced feature support and system compatibility. Physically, the module employs Small Form-factor Pluggable (SFP) interfaces, offering flexibility in network connections and compatibility with a variety of cable types. The hardware's design includes three Ethernet LED indicators for quick status checks and diagnostics. With a single Physical Layer Interface Module (PLIM) slot, the module maintains a slim profile, measuring 20.6 inches in height, 11.2 inches in depth, and 1.8 inches in width, and weighs 8.4 pounds. Despite its compact size, it requires 150 W power, fitting within the operational requirements of most network infrastructures. Network management is streamlined through the Cisco IOS XR Software Command-Line Interface (CLI), Simple Network Management Protocol (SNMP), and an Extensible Markup Language (XML) Interface. These management features offer comprehensive control and monitoring capabilities, facilitating easier management tasks and network diagnostics. Designed to operate in a wide range of environmental conditions, the module has an operating temperature range from 5 °C to 40 °C and a storage temperature range from -40 °C to 70 °C. It can withstand short-term operational extremes from -5 °C to 50 °C. The module also functions reliably in environments with humidity levels ranging from 5% to 85% for long-term operation and 5% to 90% for short-term conditions. These specifications ensure reliable performance in various installation environments. Key Features:
  • Online Insertion and Removal (OIR) support and field-replaceability for uninterrupted operation and easy maintenance.
  • Compliance with minimum and maximum operating and storage temperature and humidity requirements, ensuring durability and reliable performance under varying environmental conditions.
  • Comprehensive network management options, including CLI, SNMP, and XML interface, for efficient setup, monitoring, and troubleshooting.
The Cisco 20-1GE-FLEX module is built for those who require a reliable, high-capacity networking solution that can be easily integrated and managed within the Cisco ecosystem. Its support for OIR and field-replaceability ensures minimal downtime and easy serviceability. With its comprehensive environmental tolerance and network management features, this module is an ideal choice for organizations looking to expand their network's capabilities while maintaining high reliability and ease of use.
