Product Review

The Cisco WS-X6148E-GE-45AT module, equipped with 48 RJ-45 ports supporting 10/100/1000 speeds, is designed for versatility in network infrastructure, accommodating various Ethernet speeds and providing both PoE and PoE+ capabilities for devices requiring power over Ethernet. With support for jumbo frames up to 9216 bytes and a buffer size of 5.3 MB per port, it ensures efficient handling of large data packets, crucial for high-performance networking environments. However, its reliance on Category 5 cabling might limit throughput in scenarios demanding the highest data rates supported by more advanced cable categories, potentially affecting future scalability and performance in evolving network setups.


The Cisco WS-X6148E-GE-45AT is a high-performance, enterprise-class line card designed to meet the demanding needs of modern network environments. It is equipped with 48 ports, each capable of supporting 10/100/1000 Mbps speeds, making it versatile for a range of network requirements. This line card is specifically engineered for use with Cisco Catalyst 6500 Series switches, providing a seamless integration and enhanced capabilities for network operations. One of the key features of this module is its support for Power over Ethernet (PoE) and PoE+, enabling the delivery of power along with data over the network cabling. This functionality is crucial for deploying modern network devices such as IP cameras, VoIP phones, and wireless access points without the need for additional power supplies, simplifying installations and reducing costs. The WS-X6148E-GE-45AT utilizes RJ-45 connectors, which are widely used and ensure compatibility with a broad range of network equipment. With a maximum distance of 100 meters, it supports deployments across extended areas, suitable for large office spaces, warehouses, and campuses. The line card is designed to work with Category 5 cabling, a common standard that provides a balance between performance and cost. This module also excels in handling large volumes of data efficiently. It supports jumbo frames up to 9216 bytes, significantly larger than the standard Ethernet frame size. This capability is critical for optimizing the performance of high-throughput applications, reducing overhead, and improving data transfer rates across the network. In terms of traffic management and quality of service (QoS), the WS-X6148E-GE-45AT offers advanced features to ensure smooth operation and prioritization of critical network traffic. Each port is equipped with a sophisticated queueing mechanism, configured as Tx-1p3q8t and Rx-1q2t, which allows for precise control over packet transmission and reception. This ensures that priority traffic such as voice and video is delivered efficiently, even in congested network scenarios. The buffer size per port is 5.3 MB, providing ample capacity to handle bursts of traffic and minimizing packet loss during peak periods. This is particularly important in environments where high data loads are common, ensuring that all network communications are reliable and uninterrupted. Additionally, the line card adheres to industry standards, including IEEE 802.3af and IEEE 802.3at, guaranteeing compatibility with a wide range of PoE devices and allowing for a flexible and scalable network infrastructure. Key highlights include: - 48 ports with 10/100/1000 Mbps speed for versatile connectivity options. - Support for PoE and PoE+ to power devices directly through network cables, simplifying infrastructure. - Jumbo frames support up to 9216 bytes, enhancing data efficiency across the network. In summary, the Cisco WS-X6148E-GE-45AT is a feature-rich line card that provides high-speed connectivity, advanced QoS features, and PoE capabilities, making it an ideal choice for enterprises looking to upgrade or expand their network infrastructure. Its compatibility with the Cisco Catalyst 6500 Series ensures a reliable and high-performance networking solution that meets the challenges of today's dynamic network environments.
