Cisco C9300-48T-E

Overview

The Cisco C9300-48T-E is a 48-port Gigabit Ethernet managed switch designed to deliver high-speed connectivity, flexibility, and robust security for growing enterprise networks. It features 48 copper downlink ports for connecting user devices and access points, along with modular uplink slots that allow you to customize fiber or copper interfaces to fit your network backbone. With a switching capacity of 256 Gbps and stacking bandwidth up to 480 Gbps, this switch handles heavy traffic loads efficiently, making it suitable for environments with numerous users, IoT devices, and high-performance wireless access points.

Built on Cisco’s Catalyst 9300 platform, it supports Software-Defined Access (SD-Access) for scalable and secure campus networks. The switch’s x86 architecture includes 8 GB of RAM and 16 GB of flash storage, enabling it to run containers and approved third-party applications directly on the device. Its 1U rack-mount chassis supports dual redundant power supplies, ensuring continuous operation in mission-critical settings such as corporate offices, universities, and healthcare facilities.

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.
