Cisco C9300-24UX-E Switch
The C9300-24UX-E is a 24-port UPOE Multigigabit 10G Layer 3 managed switch with modular uplinks. It supports StackWise-480 stacking and 560W of PoE, with Network Essentials.
Overview
The Cisco Catalyst 9300 Series is Cisco's lead stackable enterprise access platform in the Catalyst 9000 family, built on the UADP 2.0 ASIC for investment protection and high-density stacking. The modular-uplink C9300 takes a field-installable network module for 1G, multigigabit, 10G, 25G, or 40G uplinks, and Cisco positions it as the successor to the end-of-sale Catalyst 3850. The C9300-24UX-E is the 24-port multigigabit UPOE configuration at the Network Essentials tier, pairing 10G-capable access ports with UPOE, and its tier is what separates it from the otherwise-identical Network Advantage C9300-24UX-A. Network Essentials covers Layer 2 switching with routed access for a single-tier campus design. Three field-replaceable fans and dual power supplies keep it serviceable in always-on deployments.
Technical Details
The Cisco Catalyst C9300-24UX-E is a Layer 3 managed 1U rackmount access switch with 24 multigigabit Cisco UPOE ports running at up to 10G, plus a modular uplink slot, running Cisco IOS XE with the perpetual Network Essentials license. Switching capacity is 640 Gbps and forwarding rate is 476.19 Mpps. All 24 access ports deliver Cisco UPOE at up to 60 W per port; the PoE budget is 560 W with the default 1100 W power supply and scales to 1440 W with dual power supplies, enough for all 24 ports at the full 60 W. It supports Cisco StackWise-480 data stacking of up to eight members at 480 Gbps, plus Cisco StackPower. It powers multigigabit endpoints such as Wi-Fi 6 access points and high-resolution cameras.

Best For
The C9300-24UX-E suits enterprise access that connects high-throughput, high-power endpoints such as Wi-Fi 6 access points and high-resolution cameras, where each port may need up to 10G and up to 60 W, with StackWise-480 stacking. With dual power supplies the 1440 W budget covers all 24 ports at 60 W, and actual device counts depend on each powered device's power draw. The Network Essentials license fits sites whose routing stays within static routes, RIP, or a small OSPF footprint.
Not suitable if:
- you need UPOE+ at 90 W per port, since these ports deliver Cisco UPOE at up to 60 W; the Catalyst 9300X provides UPOE+
- your endpoints are only 1G, since the standard-Gigabit C9300-24U covers that without the multigigabit throughput headroom
- you want fixed built-in uplinks rather than a separately ordered network module, in which case the fixed-uplink C9300L fits better
- you need full dynamic routing, BGP, or SGT-based segmentation, since those require the Network Advantage tier on the C9300-24UX-A

Part Number Decode
- C9300 — C9300 is the platform prefix, identifying the modular-uplink Cisco Catalyst 9300 Series.
- 24 — 24 is the port count, indicating 24 access ports.
- UX — UX is the port-type marker, indicating Cisco UPOE multigigabit ports at up to 60 W and up to 10G.
- E — E is the license suffix for the perpetual Network Essentials tier.
FAQ
How much PoE power does the Cisco Catalyst C9300-24UX-E provide?
The Cisco Catalyst C9300-24UX-E delivers Cisco UPOE at up to 60 W per port on all 24 multigigabit access ports. With the default 1100 W power supply the PoE budget is 560 W, and dual power supplies scale it to 1440 W, which is enough for all 24 ports to draw the full 60 W at once (24 x 60 W = 1440 W). The budget, together with the installed power supplies, determines how many devices draw full power simultaneously.
How fast are the access ports on the C9300-24UX-E?
All 24 access ports on the C9300-24UX-E are multigigabit and run at up to 10G, auto-negotiating 100M, 1G, 2.5G, 5G, and 10G over structured copper. That makes it suited to Wi-Fi 6 access points and other endpoints that exceed 1G, and each port also delivers Cisco UPOE at up to 60 W. Switching capacity is 640 Gbps.
What uplink options does the C9300-24UX-E support?
The C9300-24UX-E has a modular uplink slot rather than fixed uplink ports. It accepts a Cisco Catalyst 9300 Series network module, with options spanning 4x 1G, 4x multigigabit, 8x 10G, 2x 25G, and 2x 40G; Catalyst 3850 network modules are also compatible. The network module is ordered separately. Specific transceiver compatibility should be verified against the manufacturer's transceiver compatibility matrix at tmgmatrix.cisco.com. Transceivers are sold separately.
How many C9300-24UX-E switches can you stack?
The C9300-24UX-E supports Cisco StackWise-480 data stacking of up to eight members at 480 Gbps of stack bandwidth, and Cisco StackPower for shared power and power redundancy across the stack. It stacks with other C9300 models, including mixed stacks with C9300X, and does not stack with C9300L, Catalyst 9200, or other series. StackWise and StackPower cables are ordered separately.
What is the difference between the C9300-24UX-E and the C9300-24UX-A?
The two switches are identical hardware and differ only in license tier. The -E model ships with perpetual Network Essentials, which covers Layer 2 plus basic routed access such as static routing, RIP, EIGRP stub, OSPF for up to 1,000 routes, PBR, PIM stub multicast, and VRRP. The -A model ships with perpetual Network Advantage, which adds full OSPF, EIGRP, BGP, IS-IS, HSRP, VRF, VXLAN, LISP, and SGT segmentation. SD-Access is enabled by the term-based Cisco Catalyst subscription rather than the perpetual tier.
Does the C9300-24UX-E require a subscription to operate?
No. The switch runs on its included perpetual base license indefinitely. Under Cisco's ordering model, new switch orders include a term-based Cisco DNA or Cisco Catalyst software subscription of the same tier as the network license; that subscription unlocks Cisco Catalyst Center and cloud-managed features. When the subscription term ends, the switch continues operating on the perpetual base license capabilities after a reload.
Does the Cisco Catalyst 9300 replace an older switch?
Yes. Cisco's migration guidance positions the Catalyst 9300 as the successor to the end-of-sale Catalyst 3850. Migrating from a 3850 to the C9300-24UX-E moves the access layer to Cisco IOS XE, StackWise-480 stacking, StackPower, and multigigabit UPOE, and existing Catalyst 3850 network modules remain compatible with the 9300.
Is the C9300-24UX-E still current, and where is its lifecycle status published?
Network Devices Inc. sells the C9300-24UX-E as current, new, factory-sealed stock. Cisco publishes End-of-Sale and End-of-Life status for every Catalyst 9300 Series part number on its official End-of-Life and End-of-Sale Notices page for the series, which is the authoritative source for a specific SKU. Buyers standardizing on a platform for a multi-year refresh should confirm the current status there before ordering.
What condition is the C9300-24UX-E sold in, and what warranty applies?
The C9300-24UX-E is sold new and factory-sealed. It is covered by a Network Devices Inc. one-year warranty and a 30-day return policy.
