Cisco WS-X6748-GE-TX=

Overview

The Cisco WS-X6748-GE-TX= is an Express Forwarding 720 interface module designed to expand a compatible Cisco chassis with forty-eight Gigabit Ethernet ports. Each port supports line-rate 10/100/1000 Mbps forwarding, enabling servers, storage systems, and campus users to transfer data efficiently without bottlenecks. With a switching fabric bandwidth of up to 720 Gbps, this module is built to handle high traffic volumes in large enterprise and service provider networks.

This module supports advanced network features such as VLAN tagging, Quality of Service (QoS), and Jumbo Frame handling, allowing network engineers to segment traffic, prioritize critical applications, and optimize large file transfers. It also integrates high availability protocols like HSRP and VRRP to maintain gateway uptime in case of primary path failures.

Connectivity and compatibility

This module integrates seamlessly with Cisco chassis designed for Express Forwarding 720 interface cards, providing a dense aggregation point for network traffic. The forty-eight copper Gigabit Ethernet ports support auto negotiation and full-duplex operation, ensuring compatibility with a wide range of network devices including servers, storage arrays, and user endpoints. Compliance with IEEE 802.3 and 802.1Q standards guarantees interoperability with existing network infrastructure.

Installation and setup

Installation involves sliding the module into an available slot in the compatible Cisco chassis and connecting standard copper Ethernet cables. Once physically installed, the ports can be enabled and configured through the existing network management console, allowing for quick deployment without complex setup procedures. The module’s compact size and plug-in design make it easy to add or replace without disrupting other components.

Ideal uses and environments

This module is well suited to large enterprise networks and service providers that require high port density and robust performance. It works effectively in data centers, wiring closets, and campus networks where high throughput and reliable connectivity are essential. The support for VLANs, QoS, and redundancy protocols makes it a strong choice for environments that demand traffic segmentation, prioritized application delivery, and continuous uptime.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
