The Cisco Catalyst C9300-24UX-A is a high-performance, stackable multigigabit access switch engineered to eliminate bandwidth bottlenecks in modern enterprise networks. Designed for high-density wireless, IoT, and smart building deployments, this switch delivers 24 Multigigabit (mGig) ports supporting speeds from 100 Mbps to 10 Gigabit Ethernet over existing Cat5e/Cat6 cabling - allowing organizations to upgrade to Wi-Fi 6/6E without costly infrastructure replacement.
Each port supports Cisco Universal Power over Ethernet (UPOE), delivering up to 60W per port to power high-performance devices such as Wi-Fi 6/6E access points, PTZ security cameras, 4K digital signage, virtual desktop terminals, and building automation systems. With a 490W PoE budget (expandable with additional power supplies), the C9300-24UX-A is built for dense device environments.
Powered by Cisco’s UADP 2.0 ASIC architecture and running Cisco IOS XE with Network Advantage, this switch provides full Layer 3 routing, advanced segmentation, MPLS, and Cisco SD-Access capabilities for scalable, policy-driven networking. StackWise-480 technology enables stacking up to eight switches, delivering up to 480 Gbps stacking bandwidth, while StackPower allows power sharing and redundancy across the stack.
Security is built into the hardware with Secure Boot, AES-256 MACsec encryption, and Encrypted Traffic Analytics (ETA) to detect threats within encrypted traffic. Additionally, Perpetual PoE ensures connected devices remain powered during switch reloads and upgrades.
Ideal for enterprise campuses, smart buildings, and high-performance wireless environments, the Cisco C9300-24UX-A delivers future-ready connectivity, security, and scalability.

FAQs:
Q1. Does this switch support 10G on all 24 ports?
Yes. All 24 copper ports are Multigigabit capable and can negotiate up to 10Gbps speeds, provided the cabling (Cat6/6a) and connected devices support it.
Q2. What is the benefit of the "Network Advantage" license over "Network Essentials"?
Network Advantage (this model) enables full Layer 3 routing capabilities, including BGP, VRF-lite, and MPLS, as well as the ability to participate as a core/border node in a Cisco SD-Access fabric.
Q3. Can I increase the 490W PoE budget?
Yes. By installing a second 1100W AC power supply (PWR-C1-1100WAC-P) in the secondary power slot, you can increase the total available UPOE budget to support more high-power devices.
Q4. Are the stacking cables included?
No. StackWise-480 and StackPower cables are sold separately and come in various lengths (0.5m, 1m, 3m).
Q5. Does it support Wi-Fi 6E access points?
Absolutely. With 10G mGig ports and 60W UPOE, it provides the exact power and bandwidth requirements necessary for high-end Wi-Fi 6E APs like the Cisco Catalyst 9136 series.
