C9300L-48P-4G-A Description
The C9300L-48P-4G-A is a Cisco Catalyst 9300L fixed-uplink access switch with Network Advantage, built for wiring closets that power phones, access points and cameras. The switch has 48 10/100/1000 Mbps PoE+ ports sharing a 505W budget on the default 715W supply, four fixed 1G SFP uplinks and 104 Gbps of switching capacity. The uplinks stay at 1G because the chassis has no network module slot, and StackWise-320 stacking needs an optional stack kit of two adapters and a cable.

Product Performance
Key Features
Network Advantage lifts the 1,000-route OSPF ceiling of Network Essentials and adds BGP, IS-IS, HSRP and full EIGRP. VRF, VXLAN, LISP and Cisco TrustSec with SGT come with it, and links can run MACsec-256 where Essentials stops at MACsec-128.
The four uplink ports take 1G SFP optics and are part of the chassis, so their speed cannot be raised later with a module. With all 48 access ports at line rate, 48 Gbps of traffic meets 4 Gbps of uplink, a 12:1 ratio.
Up to eight Catalyst 9300L or 9300LM switches join at 320 Gbps, and this model counts 424 Gbps of switching capacity when stacked. Every member needs a stack kit and the same license level; modular-uplink Catalyst 9300 and 9300X switches cannot join.
Perpetual PoE keeps powered devices running while the switch reloads, which matters for PoE lighting and other IoT endpoints. Fast PoE restores power to endpoints as soon as the switch gets power back, before the operating system finishes loading.
The matching Cisco DNA or Cisco Catalyst Advantage subscription is what enables SD-Access fabric roles, AVC with NBAR2 and application hosting. Each 3-, 5- or 7-year Advantage term also carries a ThousandEyes synthetics license and a Cisco Spaces Extend license.
Two internal bays hold one supply and a blank from the factory, and the switch must not run with the second bay open. Three hot-swappable FAN-T2= modules cool the chassis front-to-rear and side-to-rear, and the switch keeps running if one fails.
Application Scenarios
In an SD-Access campus, the switch serves as the fabric edge on office floors, powering IP phones and access points over PoE+ while Cisco TrustSec group tags keep user and device groups apart.
Facilities teams can connect PoE+ cameras, badge readers and door controllers to the same closet switch as staff desks, with a dedicated VRF holding their routes away from the corporate network.
A branch office joins its closet switches into one StackWise-320 stack that exchanges routes with the WAN edge over BGP, while phones and access points draw power from the PoE+ ports.

C9300L-48P-4G-A and C9300L-48P-4X-A share 48 PoE+ ports, a 505W default budget and Network Advantage, but C9300L-48P-4G-A has four fixed 1G SFP uplinks and 104 Gbps of switching capacity against four 10G/1G uplinks and 176 Gbps, so any 10G uplink needs C9300L-48P-4X-A. Closets with no powered endpoints can use C9300L-48T-4G-A, which keeps the 48 copper ports and 1G uplinks without PoE. A closet that stays within Layer 2 and OSPF up to 1,000 routes, with no BGP, VRF or VXLAN, can drop to C9300L-48P-4G-E. The Essentials model moves up later only through a C9300L-LIC= term such as C9300L-48-E-A-5, which cannot sit on the original order.

Ordering Checklist
- Subscription tier: The order needs a 48-port C9300L Advantage term: C9300L-DNA-A-48-3Y, -5Y or -7Y for Cisco DNA, or C9300L-DNX-A-48-3Y, -5Y or -7Y for Cisco Catalyst. An Essentials term does not match the Network Advantage license on a new order.
- Second power supply: A second PWR-C1-715WAC-P is selected by default and C9300L-SPS-NONE removes it. Keeping it raises the PoE budget from 505W to 1220W, while an 1100W second supply gives 1440W.
- Stack kit: C9300L-STACK-KIT with a 50 cm STACK-T3 cable is added by default, with 1 m or 3 m cables selectable. A stack that includes Catalyst 9300LM switches needs C9300L-STACK-KIT2 instead.
- Power cords: Select the cord type for the destination country; the configurator defaults to North America and ships two cords with the default configuration.
- All-port PoE supplies: PoE on all ports needs 1 x PWR-C1-1100WAC-P or 2 x PWR-C1-715WAC-P. PoE+ on all ports needs 2 x PWR-C1-1100WAC-P, or 1 x PWR-C1-1100WAC-P with 1 x PWR-C1-715WAC-P or PWR-C1-715WDC.
