Cisco Catalyst C9300L-48UXG-4X-A 48-Port UPOE Switch with 4x 10G SFP+
The C9300L-48UXG-4X-A is a 48-port UPOE (12x mGig, 36x 1G) Layer 3 switch with 4x10G SFP+ uplinks. It supports StackWise-320 stacking and 675W of PoE, with Network Advantage.
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 C9300L is the fixed-uplink member of the series, and this model pairs multigigabit UPOE access ports with built-in 10G SFP+ uplinks; Cisco positions the 9300L as the successor to the end-of-sale Catalyst 3650. The C9300L-48UXG-4X-A combines twelve 10G-capable multigigabit ports with 36 Gigabit ports, all UPOE, at the Network Advantage tier. Network Advantage unlocks full dynamic routing and policy-based segmentation. Redundant fans and dual power supplies provide resilience in always-on deployments.
Technical Details
The Cisco Catalyst C9300L-48UXG-4X-A is a Layer 3 managed 1U rackmount access switch with 48 UPOE access ports, of which 12 are multigigabit up to 10G and 36 are Gigabit Ethernet, plus four fixed 1G/10G SFP+ uplinks, running Cisco IOS XE with the perpetual Network Advantage license. Switching capacity is 392 Gbps and forwarding rate is 291.66 Mpps. All 48 access ports deliver Cisco UPOE at up to 60 W per port; the PoE budget is 675 W with the default 1100 W power supply and up to 1775 W with dual power supplies. It supports Cisco StackWise-320 data stacking of up to eight members at 320 Gbps. It powers multigigabit endpoints such as Wi-Fi 6 access points.

Best For
The C9300L-48UXG-4X-A suits a mixed access layer where a subset of endpoints need multigigabit speed and high UPOE power, such as high-end Wi-Fi 6 access points alongside Gigabit endpoints, with built-in 10G uplinks and StackWise-320 stacking. Its 1775 W dual-supply budget powers a large share of the 48 UPOE ports at full 60 W, and actual device counts depend on each powered device's power draw. The Network Advantage license fits sites running full dynamic routing, BGP, or SGT-based segmentation.
Not suitable if:
- you need all 48 ports drawing the full 60 W at once, since the 1775 W dual-supply budget powers roughly 29 ports at 60 W
- you need every port to be multigigabit, since 12 ports run at up to 10G and 36 are Gigabit; the C9300-48UN or C9300X provide all-multigigabit
- you need UPOE+ at 90 W per port, since these ports deliver Cisco UPOE at up to 60 W; the Catalyst 9300X provides UPOE+
- you want modular uplinks beyond 10G, since the fixed uplinks top out at 10G; the modular C9300 or C9300X go higher

FAQ
How much PoE power does the Cisco Catalyst C9300L-48UXG-4X-A provide?
The Cisco Catalyst C9300L-48UXG-4X-A delivers Cisco UPOE at up to 60 W per port on all 48 access ports. With the default 1100 W power supply the PoE budget is 675 W, and dual power supplies raise it to 1775 W. Because 48 ports at 60 W would require 2880 W, the 1775 W ceiling powers roughly 29 ports at the full 60 W, so the budget rather than the port count sets how many devices draw maximum power. Most deployments mix lower-draw devices, so real port coverage is higher.
How many multigigabit ports does the C9300L-48UXG-4X-A have?
The C9300L-48UXG-4X-A has 12 multigigabit access ports that run at up to 10G and 36 standard Gigabit Ethernet ports, for 48 access ports in total. Not all ports are multigigabit; the twelve mGig ports suit high-throughput endpoints such as Wi-Fi 6 access points, while the remaining thirty-six serve Gigabit endpoints. All 48 ports deliver Cisco UPOE at up to 60 W.
What transceivers do the uplinks on the C9300L-48UXG-4X-A use?
The C9300L-48UXG-4X-A has four fixed SFP+ uplink ports that operate at 1G or 10G. These SFP+ slots accept 1G SFP and 10G SFP+ optics but do not support 25G SFP28 optics. Specific transceiver compatibility should be verified against the manufacturer's transceiver compatibility matrix at tmgmatrix.cisco.com. Transceivers are sold separately.
How many C9300L-48UXG-4X-A switches can you stack?
The C9300L-48UXG-4X-A supports Cisco StackWise-320 data stacking of up to eight members at 320 Gbps of stack bandwidth, using StackWise stacking cables that are ordered separately. It stacks with other C9300L switches and does not stack with the modular C9300, C9300X, Catalyst 9200, or other series. The fixed-uplink C9300L does not support Cisco StackPower.
What is the difference between the C9300L-48UXG-4X-A and the C9300L-48P-4X-A?
Both are 48-port fixed-uplink switches with 10G SFP+ uplinks at the Network Advantage tier, and they differ in PoE class and port speed. The 48UXG-4X-A delivers Cisco UPOE at up to 60 W per port and has 12 multigigabit ports plus 36 Gigabit, with 392 Gbps of switching capacity. The 48P-4X-A delivers PoE+ at up to 30 W per port on all-Gigabit ports, with 176 Gbps of switching capacity. Choose the 48UXG for higher per-port power and multigigabit endpoints.
Does the C9300L-48UXG-4X-A 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 9300L replace an older switch?
Yes. Cisco's migration guidance positions the Catalyst 9300L as the successor to the end-of-sale Catalyst 3650. Migrating from a 3650 to the C9300L-48UXG-4X-A moves the access layer to Cisco IOS XE, StackWise-320 stacking, 10G uplinks, and multigigabit UPOE with the Network Advantage feature set.
Is the C9300L-48UXG-4X-A still current, and where is its lifecycle status published?
Network Devices Inc. sells the C9300L-48UXG-4X-A 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 C9300L-48UXG-4X-A sold in, and what warranty applies?
The C9300L-48UXG-4X-A is sold new and factory-sealed. It is covered by a Network Devices Inc. one-year warranty and a 30-day return policy.
