Cisco Catalyst 9300 Series Switches are stackable enterprise access switches for high-density campus closets, secure segmentation, Wi-Fi 6 and Wi-Fi 7 readiness, mGig, UPOE or UPOE+, modular uplinks, and Catalyst Center operations. Buyers compare C9300, C9300L, C9300X, and newer C9350 options when standardizing critical access networks for users, phones, cameras, and wireless APs.

Catalyst 9300 switches are used as enterprise campus access switches for high-density user, phone, camera, and wireless access point connectivity. They are chosen when the network needs stacking, higher PoE options, multigigabit access, modular uplinks, security, automation, and long-term campus standardization.
Catalyst 9300 is the main modular-uplink access family, 9300L is a lower-cost fixed-uplink option, and 9300X targets higher-performance access with stronger uplinks and advanced capabilities on selected models. Compare port speeds, uplinks, PoE class, StackPower, license, and software support.
Yes, many Catalyst 9300 models support higher-power PoE options such as UPOE or UPOE+, depending on the exact SKU and installed power supplies. This matters for Wi-Fi 6E, Wi-Fi 7, video endpoints, thin clients, and other devices needing more than standard PoE+.
Yes, Catalyst 9300 supports StackWise stacking on supported models and is commonly deployed as a logical access stack. Confirm stack compatibility across model variants, stack bandwidth, required cables, and software version, especially when mixing C9300, C9300L, or C9300X hardware.
StackPower lets supported Catalyst 9300 switches share power across a stack for power pooling or redundancy. It helps with PoE resiliency, but it requires compatible models, StackPower cables, correct power supplies, and a design that accounts for load after a supply failure.
Catalyst 9300 is widely used for modern wireless access because selected models offer multigigabit copper and higher PoE. For Wi-Fi 6E or Wi-Fi 7, verify AP power mode, mGig speed, uplink bandwidth, cabling category, and whether 9300X or C9350 is a better match.
Catalyst 9300 commonly uses Network Essentials or Network Advantage software levels, with subscription and support terms depending on the ordering model. Select the license by routing, SD-Access, segmentation, automation, assurance, and Catalyst Center requirements rather than by hardware alone.
Catalyst 9300 can serve small distribution or collapsed-core roles in some branch designs, especially with suitable uplinks and stacking. For larger aggregation, high 100G density, or core scale, buyers usually compare Catalyst 9500, Catalyst 9400, or Nexus switches.
Catalyst 9300 remains a proven access platform with broad deployment history. C9350 is a newer smart switch family for buyers prioritizing newer silicon, higher mGig and PoE capabilities, and future security direction. Compare availability, feature parity, licenses, management, and standardization goals.
Verify 9300 variant, port count, mGig needs, PoE class, uplink module, StackWise and StackPower parts, license level, software release, Catalyst Center or cloud monitoring support, optics, power supplies, lifecycle status, and compatibility with existing access stacks.
Cisco Catalyst 9300 switches are Cisco’s lead stackable enterprise access platform for 24-port and 48-port wiring closets that need PoE, multigigabit access, and high-bandwidth StackWise stacking. The family covers three lines — the modular-uplink Catalyst 9300, the value fixed-uplink Catalyst 9300L, and the high-performance Catalyst 9300X. Every unit here is brand-new, factory-sealed, genuine Cisco backed by the Cisco Enhanced Limited Lifetime Warranty, with in-stock SKUs ready to ship. Use the tables below to pick by port count, power, line, or license.
Each Cisco Catalyst 9300 24 port switch and Cisco Catalyst 9300 48 port switch is available across the power types below. Pick a Cisco Catalyst 9300 PoE switch, a Cisco Catalyst 9300 UPOE switch, or a Cisco Catalyst 9300 multigigabit switch from the matrix — for example the C9300-48P-A is our most popular C9300 48 port PoE switch, while the C9300-24T-A is the data-only C9300 24 port data switch.
| Power / Port type | 24-Port | 48-Port |
|---|---|---|
| Data-only | C9300-24T-A | C9300-48T-A |
| PoE+ (802.3at) | C9300-24P-A | C9300-48P-A |
| UPOE (60W) | C9300-24U-A | C9300-48U-A |
| Multigigabit (mGig) | C9300-24UX-A | C9300-48UXM-A |
| Fiber (SFP) | C9300-24S-A | C9300-48S-A |
Every Cisco Catalyst 9300 stackable switch in the modular line joins a single logical stack of up to eight members over Cisco StackWise-480 (480 Gbps), managed as one device and sharing pooled StackPower. Uplinks are field-replaceable, so a C9300 switch with 10G uplinks can later move to 25G or 40G without changing the chassis.
Cisco Catalyst 9300L switches use built-in fixed uplinks and an optional Cisco StackWise-320 (320 Gbps) kit for a lower entry cost. They stack only with other 9300L units, not with modular 9300 models.
| Model | Configuration | Fixed uplinks |
|---|---|---|
| C9300L-24T-4X-A | 24-port data | 4 × 10G |
| C9300L-48T-4X-A | 48-port data | 4 × 10G |
| C9300L-48P-4X-A | 48-port PoE+ | 4 × 10G |
| C9300L-24P-4G-A | 24-port PoE+ | 4 × 1G |
| C9300L-48UXG-4X-A | 48-port mGig UPOE | 4 × 10G |
Cisco Catalyst 9300X switches add the most headroom: Cisco StackWise-1T (1 Tbps, eight-member stacks, backward compatible with 480G), 90W UPOE+ (802.3bt), and modular uplinks up to 40G/100G or 10G/25G — plus SFP28 25G fiber models for high-throughput aggregation.
| Model | Configuration | Modular uplinks |
|---|---|---|
| C9300X-24Y-A | 24-port 25G fiber | up to 100G |
| C9300X-12Y-A | 12-port 25G fiber | up to 100G |
| C9300X-24HX-A | 24-port mGig 90W UPOE+ | up to 100G |
| C9300X-48HX-A | 48-port mGig 90W UPOE+ | up to 100G |
| C9300X-48TX-A | 48-port 10G mGig | up to 100G |
Each Catalyst 9300 SKU ships with a perpetual base license shown by the suffix. Order the Cisco Catalyst 9300 Network Essentials switch (-E) or the Cisco Catalyst 9300 Network Advantage switch (-A) to match the features your network runs.
