C9300L-48UXG-4X-E Description
The C9300L-48UXG-4X-E is a Cisco Catalyst 9300L fixed-uplink access switch built for Cisco UPOE deployments that mix Multigigabit and Gigabit endpoints on the same closet run. It carries 12 Multigigabit ports (100M/1G/2.5G/5G/10G) alongside 36 standard 10/100/1000 ports, all capable of Cisco UPOE, and pairs them with 4 fixed 10G/1G SFP+ uplinks instead of a modular uplink bay. The default PWR-C1-1100WAC-P supply delivers a 675 W PoE budget out of the box, and the chassis stacks over StackWise-320 using the C9300L-STACK-KIT2 cabling shared across the fixed-uplink C9300L and C9300LM lines. This -E variant ships with the Network Essentials license tier, covering Layer 2 switching, routed access with a 1000-route limit, and standard telemetry, which fits access-layer roles that do not require the segmentation or automation features reserved for Network Advantage.

Product Performance
Key Features
The 12 Multigigabit ports handle 10G-capable Wi-Fi 6/6E access points and cameras while the 36 standard UPOE ports keep phones and lower-draw endpoints on the same switch, letting one closet chassis cover both traffic classes without a second unit.
The 4 fixed 10G/1G SFP+ uplinks aggregate the access-layer traffic upstream without consuming a modular uplink slot, which keeps the chassis simpler to spec but removes the option to swap in a 40G or 25G uplink module later.
The default 1100W supply already clears a 675W PoE budget, enough to power a full mix of UPOE cameras and mGig access points without needing a second power supply installed on day one.
This -E SKU ships with Network Essentials, which caps routed access at 1000 routes and omits VRF, VXLAN, and MACsec-256; deployments that need those segmentation features must order the -A variant instead of relying on a license upgrade path alone.
Stacking runs over StackWise-320 using the C9300L-STACK-KIT2 cable set shared with other fixed-uplink C9300L and C9300LM switches, so members can be added for capacity without moving to modular-uplink hardware.
C9300L-48UXG-4X-E requires a minimum of Cisco IOS XE Release 16.11.1b, above the 16.5.1a baseline for the wider Catalyst 9300 Series, so a golden image shared across a mixed closet of modular C9300 and fixed-uplink C9300L switches must meet this higher floor before it is pushed to this 48-port mGig UPOE switch.
Application Scenarios
Deployed in floor wiring closets where Wi-Fi 6E access points, PoE cameras, and standard IP phones share the same row, using the mGig ports for the higher-bandwidth devices and the 1G ports for everything else.
Used as the aggregation point for a cluster of 2.5G/5G/10G-capable access points in higher-density wireless deployments, where the 12 mGig ports absorb the AP uplinks and the 4x10G fixed uplinks carry that traffic to the distribution layer.
Deployed in larger wiring closets as one member of an up-to-eight-unit StackWise-320 stack, running alongside other C9300L or C9300LM fixed-uplink switches on the same license tier as a single logical access switch.

- C9300L-48UXG-4X-E vs C9300L-48UXG-4X-A is a pure license question: the hardware, default 1100W supply, and 675W PoE budget are identical, so the choice comes down to whether the deployment needs Network Advantage features such as VRF, VXLAN, or MACsec-256; a pure Layer 2 access role with routed access under 1000 routes can stay on the -E tier and skip the Advantage subscription cost.
- Against the C9300L-48P-4X-E, the C9300L-48UXG-4X-E trades a lower default PoE budget and switching bandwidth for Multigigabit ports: the C9300L-48P-4X-E covers 48 standard 1G PoE+ ports on a smaller 715W supply for a pure Gigabit endpoint mix, while the C9300L-48UXG-4X-E’s 392 Gbps switching capacity and 12 mGig ports only pay off when at least some access points or cameras need faster-than-1G uplinks.
- Compared with the C9300L-24UXG-4X-E, the 48-port model doubles both mGig and standard port count on the same chassis footprint and PoE hardware ceiling, but it starts from a lower 675W default PoE budget than the 24-port model’s 880W; a design with fewer than 24 mixed endpoints and tight power headroom per port can standardize on the smaller chassis, while a design needing capacity for more than 24 ports should move to the 48-port SKU regardless of the default budget gap.
- Selecting between the three ultimately follows port-mix first (mGig density needed vs pure 1G PoE+), then license tier (Essentials vs Advantage), since none of these SKUs differ in stacking method or uplink type.
Selection Guide
1. Routed-Access Ceiling Sets the Advantage Upgrade Point
This SKU ships with Network Essentials, capping routed access at 1000 routes and omitting VRF, VXLAN, LISP, and MACsec-256; a design that needs network segmentation or Cisco TrustSec should move to the C9300L-48UXG-4X-A instead of assuming those features can be unlocked later without a license change.
2. Multigigabit Fabric Over the Standard PoE+ Chassis
Choosing the C9300L-48UXG-4X-E over the C9300L-48P-4X-E means giving up the smaller 715W default power supply and lower cost in exchange for 12 Multigigabit ports and a 392 Gbps switching fabric; a closet with no mGig-capable endpoints planned can stay on the C9300L-48P-4X-E and avoid paying for switching capacity it will not use.
3. 48-Port Density Against the 880W-Budget 24-Port Chassis
Moving down to the C9300L-24UXG-4X-E trades away half the port count for a higher 880W default PoE budget on the same 1100W supply; a row with fewer than 24 mixed mGig/UPOE endpoints and a need for more per-port power headroom without a second supply can standardize on the 24-port model instead.
4. Subscription Tier Follows the Built-In Network License
The Network Stack license on this hardware is Essentials, so the accompanying Cisco DNA or Cisco Catalyst software subscription must also be ordered at the Essentials tier; pairing Advantage hardware with an Essentials subscription is only permitted at renewal, not on a new order.

Ordering Checklist
|
Check Item |
What to Confirm |
Why It Matters |
|---|---|---|
|
Network Stack and subscription tier match |
Confirm the Cisco DNA or Cisco Catalyst software subscription is ordered at Network Essentials to match this hardware’s built-in license. |
Mismatched tiers are only permitted at renewal, not on a new order, and can block activation. |
|
Second power supply and blank module |
If ordering with only one PSU, confirm a blank module ships for the empty slot; if adding a second PWR-C1 unit, confirm the target PoE budget from the scaling table. |
Running with an empty, uncovered slot is against Cisco’s installation guidance and affects airflow and PoE headroom. |
|
Stack kit compatibility |
Confirm C9300L-STACK-KIT2 is included when stacking, and that any other stack members are C9300L or C9300LM fixed-uplink units. |
Fixed-uplink C9300L/LM units cannot stack with modular-uplink C9300/C9300X switches. |
|
Smart Account assignment |
Confirm the target Smart Account and Virtual Account before the order is placed. |
Catalyst 9300 Series SKUs are Smart Licensing-enabled, and a license tied to the wrong account can stall activation. |
|
SFP+/SFP optics on the fixed uplinks |
Confirm the optics chosen for the 4 fixed 10G/1G SFP+ uplinks are listed on the Cisco optics compatibility matrix. |
An unsupported optic can be rejected by the fixed uplink port even if the form factor fits. |
