Cisco C9300L-48T-4G-A Switch
The Cisco Catalyst C9300L-48T-4G-A is a 48-port data-only Layer 3 managed switch with 4x1G SFP uplinks. It supports StackWise-320 stacking and ships 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-48T-4G-A is the 48-port data-only configuration with 1G uplinks at the Network Advantage tier, which is what separates it from the otherwise-identical Network Essentials C9300L-48T-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-48T-4G-A is a Layer 3 managed 1U rackmount access switch with 48 Gigabit Ethernet (10/100/1000) data 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. It carries no Power over Ethernet, so all 48 access ports are data-only. It supports Cisco StackWise-320 data stacking of up to eight members at 320 Gbps. It connects non-powered endpoints such as desktops, printers, and wired IoT devices in campus and branch access networks.

Best For
The C9300L-48T-4G-A suits high-density enterprise campus and branch access that connects non-powered endpoints such as desktops, printers, and wired IoT devices and wants StackWise-320 stacking with built-in fiber uplinks. The four 1G SFP uplinks carry fiber back to the distribution layer, and 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-48T-4X provides 10G SFP+ uplinks
- you need to power devices such as wireless access points, IP phones, or IP cameras, since this is a data-only switch with no Power over Ethernet
- 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

Part Number Decode
- C9300L — C9300L is the platform prefix, identifying the fixed-uplink Cisco Catalyst 9300 Series.
- 48 — 48 is the port count, indicating 48 access ports.
- T — T is the port-type marker, indicating data-only Gigabit ports with no Power over Ethernet.
- 4G — 4G is the uplink code, indicating four fixed 1G SFP uplinks.
- A — A is the license suffix for the perpetual Network Advantage tier.
FAQ
Does the Cisco Catalyst C9300L-48T-4G-A support PoE?
No. The Cisco Catalyst C9300L-48T-4G-A is a data-only switch, and all 48 Gigabit Ethernet access ports carry no Power over Ethernet. It cannot power devices such as wireless access points, IP phones, or IP cameras. If you need PoE+ on the access ports, the C9300L-48P-4G-A is the equivalent PoE+ model with the same four 1G SFP uplinks and Network Advantage license.
What transceivers do the uplinks on the C9300L-48T-4G-A use?
The C9300L-48T-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-48T-4G-A switches can you stack?
The C9300L-48T-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-48T-4G-A and the C9300L-48T-4X-A?
The two switches have the same 48 data-only access ports, 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-48T-4G-A and the C9300L-24T-4G-A?
The two switches are the same fixed-uplink platform, uplink type, and license tier, and differ in access-port count and throughput. The 48T-4G-A has 48 data-only ports with 104 Gbps of switching capacity and a 77.38 Mpps forwarding rate. The 24T-4G-A has 24 data-only ports with 56 Gbps of switching capacity and a 41.66 Mpps forwarding rate. Choose the 48-port model for a denser access layer.
Does the C9300L-48T-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-48T-4G-A moves the access layer to Cisco IOS XE and StackWise-320 stacking with the Network Advantage feature set.
Is the C9300L-48T-4G-A still current, and where is its lifecycle status published?
Network Devices Inc. sells the C9300L-48T-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-48T-4G-A sold in, and what warranty applies?
The C9300L-48T-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.
