Cisco C9300L-48P-4G-A Switch – 48-Port PoE+, 1G Uplinks, Network Advantage
The Cisco Catalyst C9300L-48P-4G-A is a 48-port PoE+ Layer 3 managed switch with 4x1G SFP uplinks. It supports StackWise-320 stacking and 505W 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, with built-in SFP uplinks rather than the modular network module of the C9300, and Cisco positions it as the successor to the end-of-sale Catalyst 3650. The C9300L-48P-4G-A is the 48-port PoE+ configuration with 1G uplinks at the Network Advantage tier, which is what separates it from the otherwise-identical Network Essentials C9300L-48P-4G-E. 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-48P-4G-A is a Layer 3 managed 1U rackmount access switch with 48 Gigabit Ethernet PoE+ ports and four fixed 1G SFP uplinks, running Cisco IOS XE with the perpetual Network Advantage license. Switching capacity is 104 Gbps and forwarding rate is 77.38 Mpps. All 48 access ports deliver PoE+ at up to 30 W per port; the PoE budget is 505 W with the default 715 W power supply and scales to 1440 W with dual power supplies, enough for all 48 ports at 30 W. It supports Cisco StackWise-320 data stacking of up to eight members at 320 Gbps. It powers wireless access points, IP phones, and IP cameras in campus and branch access networks.

Best For
The C9300L-48P-4G-A suits high-density enterprise campus and branch access that powers wireless access points, IP phones, and IP cameras while serving desktops and printers, with StackWise-320 stacking and built-in fiber uplinks. How many devices it powers at once depends on each powered device's power draw and the installed power supplies, so size the PoE budget against the real load. The Network Advantage license fits sites running full dynamic routing, BGP, or SGT-based segmentation.
Not suitable if:
- you need 10G uplinks, since this model has fixed 1G SFP uplinks; the C9300L-48P-4X provides 10G SFP+ uplinks
- you need UPOE at 60 W per port, since these ports deliver PoE+ at up to 30 W; the C9300L-48UXG provides UPOE
- you need multigigabit (mGig) access ports, since this model has standard Gigabit ports
- you only need basic Layer 2 switching, since the base Network Essentials tier would be sufficient

FAQ
How much PoE power does the Cisco Catalyst C9300L-48P-4G-A provide?
The Cisco Catalyst C9300L-48P-4G-A delivers PoE+ at up to 30 W per port on all 48 Gigabit Ethernet access ports. With the default 715 W power supply the PoE budget is 505 W, and dual power supplies scale it to 1440 W, which is enough for all 48 ports to draw the full 30 W at once (48 x 30 W = 1440 W). The budget, together with the installed power supplies, determines how many devices draw full power simultaneously.
What transceivers do the uplinks on the C9300L-48P-4G-A use?
The C9300L-48P-4G-A has four fixed 1G SFP uplink ports. These are 1-Gigabit SFP slots and do not support 10G SFP+ 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-48P-4G-A switches can you stack?
The C9300L-48P-4G-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-48P-4G-A and the C9300L-48P-4X-A?
The two switches have the same 48 PoE+ access ports, the same PoE budget, the same Network Advantage license, and the same StackWise-320 stacking, and differ in uplinks and throughput. The -4G model has four 1G SFP uplinks with 104 Gbps of switching capacity and a 77.38 Mpps forwarding rate. The -4X model has four 1G/10G SFP+ uplinks with 176 Gbps of switching capacity and a 130.95 Mpps forwarding rate. Choose the -4G when the uplink to the distribution layer is 1G and will stay 1G.
What is the difference between the C9300L-48P-4G-A and the C9300L-48PF-4X-A?
Both are 48-port PoE+ fixed-uplink switches at the Network Advantage tier delivering up to 30 W per port, and they differ in PoE budget and uplinks. The 48P-4G-A has 1G SFP uplinks and a budget that scales to 1440 W with dual supplies. The 48PF-4X-A is a full-PoE+ model with 10G SFP+ uplinks and a higher default budget (890 W on a single 1100 W supply, up to 1440 W). Choose the 48PF when more of the 48 ports must draw full power from a single supply.
Does the C9300L-48P-4G-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-48P-4G-A moves the access layer to Cisco IOS XE and StackWise-320 stacking with the Network Advantage feature set.
Is the C9300L-48P-4G-A still current, and where is its lifecycle status published?
Network Devices Inc. sells the C9300L-48P-4G-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-48P-4G-A sold in, and what warranty applies?
The C9300L-48P-4G-A is sold new and factory-sealed. It is covered by a Network Devices Inc. one-year warranty and a 30-day return policy.
