Product Review

The Cisco WS-X4612-SFP-E module, with its 12 SFP ports supporting 1G speed, is tailored for enterprise and service provider environments requiring high-density, line-rate performance. Its compatibility with E-Series Supervisor Engines and support for Cisco IOS Software Release 12.2(54)SG or later ensures seamless integration into existing networks, while the capability to handle jumbo frames up to 9216 bytes and inherent QoS features from the supervisor engine enhance network efficiency and data handling. However, its operational temperature range and power consumption of 30W may limit deployment options in environments with extreme temperature variations or stringent energy efficiency requirements.


The Cisco WS-X4612-SFP-E is a line card designed to provide efficient and reliable connectivity for enterprise, mid-market, and commercial core and distribution deployments. This module is engineered to meet the demands of high-speed networking, offering a suite of features that enhance its performance and usability in a wide range of applications, including service provider GE aggregation for DSLAM/PON/mobile data backhaul. Equipped with 12 SFP ports, this module supports a port speed of 1000 Mbps, ensuring that each port can handle line-rate traffic without bottlenecks. The 1:1 wire rate guarantees that the throughput and bandwidth capacity meet the needs of data-intensive applications, making this card an ideal choice for environments that require high-speed data transmission. The Cisco WS-X4612-SFP-E is compatible with E-Series Supervisor Engines and requires Cisco IOS Software Release 12.2(54)SG or later for optimal performance. This compatibility ensures that the module can be seamlessly integrated into existing network infrastructures, providing an upgrade path that is both cost-effective and efficient. Jumbo frame support up to 9216 bytes is another notable feature, allowing the network to handle larger packets and improve overall data transmission efficiency. This capability is especially beneficial in environments where large data packets are common, as it reduces the need for packet segmentation and reassembly, thereby lowering the overhead and improving the network's throughput. Quality of Service (QoS) is an essential requirement for modern networks, and the Cisco WS-X4612-SFP-E inherits its QoS capability from the Supervisor Engine. This integration ensures that the network can prioritize traffic, guarantee bandwidth, avoid congestion, and deliver a reliable service for all applications. The module's hardware specifications are designed to ensure reliability and longevity. With a Mean Time Between Failures (MTBF) of 676,740 hours, this card is built to last. It also offers a maximum power consumption of 30 W, balancing performance with energy efficiency. Environmental conditions can significantly affect hardware performance, which is why the Cisco WS-X4612-SFP-E is engineered to operate within a wide range of temperatures, from 32° to 104°F (0° to 40°C) and can be stored in temperatures ranging from -40° to 167°F (-40° to 75°C). It also operates effectively in relative humidity conditions from 10 to 90%, noncondensing, and at altitudes ranging from -60 to 3000m, ensuring reliability across various environmental conditions.
  • 12 SFP ports for high-density connectivity.
  • Supports jumbo frames up to 9216 bytes, enhancing data transmission efficiency.
  • Robust environmental specifications ensure reliable operation under diverse conditions.
In summary, the Cisco WS-X4612-SFP-E line card provides a high-performance, reliable solution for networking environments requiring high-speed, line-rate capability. Its support for advanced features and compatibility with E-Series Supervisor Engines make it a versatile choice for a range of applications, ensuring that networks can meet the demands of modern data communications.
