Cisco WS-X4612-SFP-E=

Overview

The Cisco WS-X4612-SFP-E= is a 12-port Gigabit Ethernet line card designed to expand the connectivity of Cisco Catalyst 4500 series switches. It supports speeds of 10, 100, and 1000 Mbps on each port, allowing seamless integration of legacy devices alongside high-speed Gigabit connections. This module is ideal for environments that require efficient handling of large data transfers, such as server backups, virtualization, and video streaming, thanks to its jumbo frame support.

Key features

• 12 Gigabit SFP ports provide flexible options for network expansion and fiber connectivity.
• Plug-in module design enables easy installation directly into Catalyst 4500 series switches without additional rack space or power cords.
• Supports 10/100/1000 Mbps speeds, allowing a mix of legacy and modern devices on the same card.
• Jumbo frame support enhances performance for large data transfers, reducing overhead and improving throughput.
• Fully compatible with Cisco Catalyst 4500 management software, ensuring consistent operation and simplified network administration.
• Automatic detection by the switch upon installation streamlines setup and reduces downtime.

Connectivity and compatibility

This line card integrates seamlessly with Cisco Catalyst 4500 series switches, using the same management interface and software features. It supports small form-factor pluggable (SFP) transceivers, which provide flexibility for fiber or copper connections depending on your network needs. The ability to mix different speeds on the same card helps maintain compatibility with a variety of devices across your network.

Installation and setup

Installation involves sliding the module into an available slot in the Catalyst 4500 chassis and securing it in place. The switch automatically recognizes the new card, simplifying deployment and minimizing network disruption. This modular approach allows phased upgrades, so you can add ports as your bandwidth demands grow without replacing the entire switch.

Ideal uses and environments

This line card is well suited for enterprise campus networks and data centers that require scalable access-layer connectivity. It works effectively in wiring closets aggregating user workstations or in server rows where consistent Gigabit performance is essential. The combination of legacy device support and high-speed ports makes it a practical choice for networks undergoing gradual modernization.

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.
