What is Cisco C9300-24UX-A designed for?

Cisco C9300-24UX-A is designed for 24-port multigigabit UPOE access with modular uplinks and Network Advantage licensing. It fits access closets serving high-speed wireless APs, video endpoints, or devices that need more than standard 1G PoE+ access.

How is C9300-24UX-A different from C9300-24UX-E?

C9300-24UX-A includes Network Advantage, while C9300-24UX-E includes Network Essentials. The access hardware is aligned, so the A SKU is selected when Layer 3, segmentation, or policy features are required from day one.

How is C9300-24UX-A different from C9300-24P-A?

C9300-24UX-A provides multigigabit access and UPOE, while C9300-24P-A provides 1G PoE+. Choose the UX model when access points or edge devices need higher copper speed or more endpoint power.

Can C9300-24UX-A be used for Wi-Fi 6 access points?

Yes. C9300-24UX-A is well suited for Wi-Fi 6 and similar high-performance AP deployments because it provides multigigabit copper access and UPOE. Uplink modules should be sized so AP traffic is not constrained upstream.

What uplink modules should be considered for C9300-24UX-A?

C9300-24UX-A can use Catalyst 9300 modular uplinks, and many designs pair multigigabit access with 10G, 25G, or faster uplink options. The best module depends on the number of high-speed endpoints and upstream switch capacity.

Does C9300-24UX-A support StackPower?

Yes. C9300-24UX-A supports StackPower, which is useful when UPOE endpoint power resiliency matters. Power budget, redundancy mode, and power supply selection should be planned before deployment.

When should I choose C9300-48U-A instead of C9300-24UX-A?

Choose C9300-48U-A when the site needs 48 UPOE-capable 1G access ports. Choose C9300-24UX-A when 24 multigigabit UPOE ports are more valuable than higher port count.

When is C9300-24UX-A more than the site needs?

C9300-24UX-A may be more than the site needs when endpoints only require 1G and standard PoE+. C9300-24P-A can be a cleaner choice for those access closets.

C9300-24UX-A Description

The C9300-24UX-A is a Cisco Catalyst 9300 Series access switch built around 24 Multigigabit copper ports, each negotiating 100 Mbps, 1G, 2.5G, 5G, or 10G and supporting Cisco UPOE power delivery to the connected device. It carries a modular uplink bay rather than a fixed uplink, so the operator selects the uplink speed and media by installing a network module such as the 8x 10G/1G C9300-NM-8X or the 2x 40G C9300-NM-2Q rather than being locked into a factory-fixed port set. The -A ordering line ships with Network Advantage, the Catalyst 9300 license tier that adds advanced routing, network segmentation, and automation entitlements to the same 24-port mGig UPOE hardware sold as the Network Essentials C9300-24UX-E. With the default PWR-C1-1100WAC-P supply installed, the switch provides a 560W PoE budget, and it joins the Catalyst 9300 StackWise-480 fabric for up to eight units in a single stack with StackPower support for shared power redundancy. The combination of 10G-capable copper ports and UPOE headroom targets access-layer deployments where endpoints need more than standard PoE+ power or more than 1G of bandwidth on the same cable run.

Key Features

Multigigabit UPOE Access Density

Each of the 24 copper ports can negotiate up to 10G and deliver Cisco UPOE, letting a single closet uplink carry Wi-Fi 6/6E access points, PTZ cameras, or other high-draw endpoints that exceed standard PoE+ without moving to a different switch line.

Modular Uplink Flexibility

The uplink bay accepts a range of C9300 network modules, from 4x 1G to 2x 40G, so the same base switch can be provisioned for a 1G distribution link at install and later re-fitted with a higher-speed module as the uplink requirement grows, without replacing the chassis.

Network Advantage License Scope

The -A ordering line unlocks advanced routing protocols, VRF/VXLAN segmentation, and model-driven automation (NETCONF/RESTCONF/YANG) that are not available on the Network Essentials variant, which matters for access switches that also need to participate in Layer 3 segmentation or automated provisioning.

StackWise-480 and StackPower Scaling

Up to eight C9300-24UX-A units can be joined into a single StackWise-480 fabric with a shared 480 Gbps stack bandwidth, and StackPower lets stack members share power budget so a unit with a failed supply can keep running PoE loads from a neighbor’s spare capacity.

Dual Power Supply Headroom

The switch has two internal power bays and ships with one 1100W supply installed; adding a second supply raises the available PoE ceiling to the platform’s 1440W design limit, which matters for closets that plan to populate most or all 24 ports with UPOE-class devices.

Altitude Narrows The Operating Temperature Ceiling

C9300-24UX-A holds its full 45C operating ceiling only up to 5000 ft; above that it narrows to 35C at 15,000 ft, and a cold start needs at least 32F (0C) ambient, so a high-altitude equipment room or an unheated space needs to be checked against these limits before the switch is installed there.

Application Scenarios

Campus Access Wiring Closet

Deployed as the access-layer switch in a floor wiring closet, providing Multigigabit UPOE drops for access points, PTZ cameras, and desktop endpoints that need more power or bandwidth than a standard PoE+ port delivers.

High-Density Wireless Access Layer

Used to aggregate a cluster of Wi-Fi 6/6E access points on Multigigabit UPOE ports, matching the access point’s multi-gigabit uplink requirement without requiring a separate mGig-only switch line.

Segmented Campus Edge

Placed at the edge of a segmented campus network where Network Advantage features such as VRF, VXLAN, or Cisco TrustSec are needed directly at the access layer rather than only at the distribution tier.

The core difference between C9300-24UX-A and C9300-48UXM-A is port count and per-port ceiling: the C9300-48UXM-A doubles port density to 48 but reserves full 10G Multigigabit only on 12 of those ports, while the C9300-24UX-A gives all 24 ports a 10G ceiling and a higher 560W default PoE budget versus the C9300-48UXM-A’s 490W, so a design that needs fewer ports but full 10G reach on every one of them favors the C9300-24UX-A over spreading the same budget across twice the ports.
Against C9300-24T-A, the same 24-port chassis loses both Multigigabit speed and PoE entirely: the C9300-24T-A ships with a 350W supply that carries no PoE budget at all, so it only fits when every downstream device is locally powered and 1G copper is sufficient, while the C9300-24UX-A’s 640 Gbps switching capacity versus the C9300-24T-A’s 208 Gbps reflects the cost of adding Multigigabit and UPOE hardware.
Compared with C9300-24H-A, both switches share the 1100W default supply and 24-port chassis, but the C9300-24H-A trades Multigigabit port speed for a higher 830W UPOE+ budget on standard Gigabit ports, so a closet with mostly 1G endpoints that need maximum PoE headroom fits the C9300-24H-A better, while a closet needing 10G-capable access ports for a smaller number of high-bandwidth devices fits the C9300-24UX-A.
Ordering between these four therefore comes down to two questions in sequence: does the deployment need any PoE budget at all (ruling out C9300-24T-A if not), and does it need 10G Multigigabit reach on the access ports (favoring C9300-24UX-A) or maximum PoE headroom on standard Gigabit ports (favoring C9300-24H-A) or higher port count with partial Multigigabit reach (favoring C9300-48UXM-A); license tier and default power supply family do not differentiate this group since all four share Network Advantage and the PWR-C1 supply line.

Selection Guide

1. Essentials PID Skips the Advantage Subscription Cost

The C9300-24UX-A PID carries Network Advantage; the identical hardware ordered as C9300-24UX-E carries Network Essentials instead, so a deployment that only needs Layer 2 access switching without VRF, VXLAN, or advanced routing can move to the Essentials PID and skip the Advantage-tier software subscription cost.

2. Full 10G Reach Across 24 Ports Over 48-Port Partial Reach

Choosing between the C9300-24UX-A and the C9300-48UXM-A is a tradeoff between full 10G reach and port density: the C9300-24UX-A gives every one of its 24 ports a 10G ceiling, while the C9300-48UXM-A spreads the same modular-uplink hardware across 48 ports but limits full Multigigabit speed to only 12 of them, so a design needing more than 24 access points at Multigigabit speed does not fit either SKU cleanly and should be evaluated against the higher-port Multigigabit models before defaulting to the C9300-48UXM-A.

3. 830W UPOE+ Headroom Trades Away the Multigigabit Ceiling

Against the C9300-24H-A, the C9300-24UX-A gives up 270W of default PoE budget (560W against 830W) in exchange for a 10G-capable port instead of a Gigabit-only port; a closet that needs to power UPOE+ lighting or high-draw endpoints across most of its 24 ports without adding a second supply is better served by the C9300-24H-A, while a closet that needs Multigigabit uplink speed on a subset of access points should keep the C9300-24UX-A.

4. Stacking With Existing Catalyst 9300 Members

The C9300-24UX-A joins a StackWise-480 stack only with other standard Catalyst 9300 modular-uplink members at the same Network Advantage license tier; a row already built from Catalyst 9300X or Catalyst 9300L switches cannot add this SKU into the same stack, so extending an existing mixed-platform row calls for a same-platform model instead.

PoE Power Planning

Planning Item	Value or Check
Default PoE budget	560W with the single default PWR-C1-1100WAC-P supply installed.
Extended PoE budget	Up to 1440W design ceiling when a second PWR-C1-1100WAC-P or PWR-C1-1900WAC-P supply is added.
Power supply confirmation	Confirm which power supply model is actually installed before assuming the extended PoE ceiling applies.
PoE standard support	Cisco UPOE on all 24 Multigigabit ports; endpoint must support UPOE or a lower PoE/PoE+ standard to negotiate power.
Device count check	Sum the power draw of all planned UPOE/PoE+ endpoints against the installed supply’s budget before finalizing port assignments.
StackPower option	Confirm whether StackPower sharing across stack members is planned, since it changes how PoE budget is pooled across a stack.

Ordering Checklist

Check Item	What to Confirm	Why It Matters
Network module selection	Confirm which C9300 network module (C9300-NM-4G, C9300-NM-4M, C9300-NM-8X, C9300-NM-2Q, or C9300-NM-2Y) is being ordered alongside the switch, or confirm C9300-NM-BLANK if none is needed at install.	The uplink bay ships empty; without a module or blank filler, the switch has no uplink path and improper airflow.
Software subscription tier match	Confirm the Cisco Catalyst or Cisco DNA software subscription ordered is Advantage tier to match the Network Advantage hardware license on this PID.	A tier mismatch at new purchase is not accepted; Essentials-tier subscriptions on Advantage hardware are only allowed at renewal.
Smart Account binding	Confirm the target Smart Account and Virtual Account before placing the order.	Catalyst 9300 switches are Smart Licensed; a license tied to the wrong account can stall activation after delivery.
Second power supply need	Confirm whether a second PWR-C1-1100WAC-P or PWR-C1-1900WAC-P is required to reach the higher PoE ceiling.	The default single-supply configuration caps available PoE at 560W; underestimating PoE load across 24 UPOE ports can leave endpoints unpowered.
Network module cross-compatibility	Confirm any network module ordered is from the Catalyst 9300 (non-X) module family.	Catalyst 9300X modules do not fit Catalyst 9300 modular uplink bays even though the PID naming looks similar.

Yes. C9300-24UX-A supports StackPower, which is useful when UPOE endpoint power resiliency matters. Power budget, redundancy mode, and power supply selection should be planned before deployment.
When should I choose C9300-48U-A instead of C9300-24UX-A?
Choose C9300-48U-A when the site needs 48 UPOE-capable 1G access ports. Choose C9300-24UX-A when 24 multigigabit UPOE ports are more valuable than higher port count.
When is C9300-24UX-A more than the site needs?
C9300-24UX-A may be more than the site needs when endpoints only require 1G and standard PoE+. C9300-24P-A can be a cleaner choice for those access closets.
