Cisco Catalyst C1300-48P-4G 48-Port Layer 3 Managed PoE+ Switch, 4x1G SFP
The Cisco Catalyst C1300-48P-4G is a 48-port PoE+ Layer 3 managed switch with 4x 1G SFP uplinks. It delivers 375W of PoE and supports dynamic Layer 3 routing.
Overview
The Cisco Catalyst 1300 Series is a line of fixed, managed, enterprise-class Layer 3 switches for small and medium-sized business and branch offices, and Cisco positions it as the next-generation successor to the Cisco Business CBS350 Series managed switches. The C1300-48P-4G is the 48-port PoE+ configuration with four 1G SFP uplinks, running a customized Linux-based operating system rather than Cisco IOS. Its Layer 3 feature set covers static routing and RIP v2 for inter-VLAN routing and network segmentation into workgroups; the more advanced OSPF dynamic routing is offered only on the Catalyst 1300X models, not on this switch. A single internal fan cools the switch under its higher port and power load while keeping operation quiet enough for deployment outside the wiring closet.
Technical Details
The Cisco Catalyst C1300-48P-4G is a Layer 3 managed 1U rackmount switch with 48 Gigabit Ethernet (10/100/1000) PoE+ ports and four 1G SFP uplinks, running a customized Linux-based operating system. Switching capacity is 104 Gbps and forwarding rate is 77.38 Mpps. It supplies a 375W PoE+ power budget across the 48 access ports under IEEE 802.3at, at up to 30 W per port. Layer 3 routing covers static routing and RIP v2. It connects and powers devices such as wireless access points, IP phones, and IP cameras at the access layer in small business and branch networks.

Branch Office
Best For
The Cisco Catalyst C1300-48P-4G suits small business and branch access deployments that connect and power devices such as wireless access points, IP phones, and IP cameras over a single Ethernet cable. A 375W PoE+ budget is suitable for mixed deployments of these powered devices; actual device counts depend on each device's power draw. The four 1G SFP uplinks aggregate traffic back to the distribution layer, and the switch is managed through the Cisco Business Dashboard, mobile app, web UI, and CLI.
Not suitable if:
- you need to power a large number of high-draw PoE+ devices, since this model's 375W shared budget is smaller than the 740W budget of the Full PoE+ C1300-48FP-4G, which supports denser deployments
- you need 10G uplinks, since this model has fixed 1G SFP uplinks
- you need switch stacking, since this model does not support stacking (Front Panel Stacking is available only on specific Catalyst 1300 models explicitly listed by Cisco)
- you need OSPF or other advanced dynamic routing, since this model supports only static routing and RIP v2
- you need multigigabit (mGig) access ports, since the access ports are 1 Gigabit Ethernet

FAQ
How much PoE does the Cisco Catalyst C1300-48P-4G provide?
The Cisco Catalyst C1300-48P-4G provides a 375W PoE+ power budget across its 48 Gigabit Ethernet access ports, compliant with IEEE 802.3at and delivering up to 30 W per port. This 375W budget is suitable for mixed deployments of powered devices such as wireless access points, IP phones, and IP cameras; actual device counts depend on each powered device's power draw.
What transceivers do the uplinks on the C1300-48P-4G use?
The Cisco Catalyst C1300-48P-4G has four fixed 1G SFP uplink ports. These are 1-Gigabit slots and do not accept 10G SFP+ optics; 10G-capable uplinks and ports are available on selected Catalyst 1300 models. Specific transceiver compatibility should be verified against the supported-SFP module list in the Cisco Catalyst 1300 Series data sheet and Cisco's transceiver compatibility matrix. Transceivers are sold separately.
Can the Cisco Catalyst C1300-48P-4G be stacked?
No. The Cisco Catalyst C1300-48P-4G does not support stacking. Front Panel Stacking is available only on specific Catalyst 1300 models explicitly listed by Cisco, and all stack members must belong to the same stacking family. Multiple C1300-48P-4G units can still be deployed and managed centrally through the Cisco Business Dashboard.
What is the difference between the C1300-48P-4G and the C1300-48FP-4G?
Both are 48-port Gigabit Ethernet Layer 3 switches with four 1G SFP uplinks and the same customized Linux-based operating system; they differ in PoE budget. The C1300-48P-4G provides a 375W PoE+ budget for lighter powered deployments, while the Full PoE+ C1300-48FP-4G provides a 740W budget for denser powered-device deployments. The data-only C1300-48T-4G drops PoE entirely.
What Layer 3 routing does the Cisco Catalyst C1300-48P-4G support?
The Cisco Catalyst C1300-48P-4G is a Layer 3 switch that supports static routing and RIP v2 dynamic routing, plus inter-VLAN routing across up to 128 IP interfaces and up to 990 IPv4 routes. It does not support OSPF, BGP, or EIGRP; OSPF is added only on the Catalyst 1300X models. This routed-access feature set lets the switch segment a small or branch network into VLAN workgroups and route between them without a separate router handling internal traffic.
Does the Cisco Catalyst C1300-48P-4G replace the Cisco Business CBS350?
Yes. Cisco positions the Catalyst 1300 Series as the next-generation successor to the Cisco Business CBS350 Series managed switches, which Cisco moved to End-of-Sale in 2024. The Cisco Catalyst C1300-48P-4G is a Layer 3 replacement for a comparable CBS350 managed model, carrying forward managed Layer 3 switching, the same access-port and uplink layout, and Cisco Business Dashboard and mobile-app management on a customized Linux-based operating system.
Is the Cisco Catalyst C1300-48P-4G end of life?
No. Cisco has not published an End-of-Sale or End-of-Life notice for the Cisco Catalyst 1300 Series, and the Cisco Catalyst C1300-48P-4G remains a current, actively shipping product. The Catalyst 1300 Series is Cisco's current small-business and branch managed switching line and carries a Cisco limited lifetime hardware warranty with return-to-factory replacement. Buyers should re-verify status on Cisco's official End-of-Life and End-of-Sale notices page before purchase.
What condition is the C1300-48P-4G sold in, and what warranty applies?
The Cisco Catalyst C1300-48P-4G is sold new and factory-sealed. It is covered by a Network Devices Inc. one-year warranty and a 30-day return policy.
