Stackable Copper Access With Flexible Fiber Connections
SG350X-48 combines 48 Gigabit Ethernet access ports with fixed 10G uplinks in a managed, non-PoE, Layer 2+ switch. Two dedicated SFP+ interfaces sit alongside two 10GBASE-T/SFP+ combo interfaces; each combo connection uses either copper or fiber, not both simultaneously. The full-width 1U chassis belongs to the Cisco 350X Series Stackable Managed Switches and serves small-business access networks connecting independently powered endpoints. The discontinued SG350X-48P differs by supplying PoE+ from its access ports. Copper access and a choice of uplink media let a buyer retain Gigabit endpoint connections while specifying a faster connection toward the rest of the network. The port layout fixes the uplink architecture at purchase rather than leaving an expansion-card selection for later.

SG350X-48 Use Case
Enterprise Campus Core Switch for Unified Communications and VLAN Segmentation
A mid-size enterprise deploys the SG350X-48-48 x 10/100/1000 ports, 4x10 Gigabit Ethernet (2x10GBase-T/SFP+ combo + 2xSFP+) as the core distribution switch across three office buildings. It aggregates access switches over 10G SFP+ fiber, enforces VLAN segmentation for Finance, HR and Guest networks, and applies QoS policies to prioritize VoIP and video conferencing. Benefit: consistent sub-5 ms latency, 40% reduction in call jitter, secure traffic isolation and centralized Smart Switch management that cuts operational overhead by 30%.
Data Center Leaf-Spine Connectivity for Virtualized Server Clusters
In a 50-node VMware data center, the SG350X-48-48 serves as a leaf switch, linking each hypervisor with redundant 10GBase-T uplinks and MLAG to dual spine switches. It segments production, backup and management VLANs and leverages LACP for aggregated throughput. Benefit: uninterrupted live migrations, 80 Gbps of bi-directional bandwidth, sub-microsecond latency and zero single points of failure for maximum availability.
High-Performance 4K Media Collaboration in Post-Production Studios
A broadcast facility uses the SG350X-48-48 to connect 4K editing suites, shared NAS arrays and offsite backup appliances. Workstations run on 1 Gbps access ports, while storage servers attach via dual 10GBase-T/SFP+ links. The switch enforces jumbo frames and traffic shaping for real-time video streams. Benefit: 60% faster large-file transfers, frame-accurate playback during editing and unified management through Cisco’s intuitive GUI.
Best For
Existing Stack Expansion
When an existing stack needs another member, the 350X family permits mixed SG350X, SG350XG and SX350X members within one hardware stack. Cross-stack link aggregation and master/backup control affect the connection plan. Confirm the installed member families and assign the interconnect ports before specifying the expansion order.
IPv6 Routing Staging
When IPv6 traffic must pass between local networks, the 350X family supports 245 IPv6 static routes and 106 IPv6 interfaces. These are separate limits from IPv4 routing resources. Inventory the required IPv6 destinations and interface assignments, then confirm the configuration fits those limits before issuing the purchase order.
Multi-Site Configuration Orders
When several sites need the same switch configuration, the 350X family supports text-editable configuration files and secure mass deployment through SCP file download. Cisco PnP Connect provides another provisioning path. Prepare the configuration file, management addressing and provisioning method, then specify staging requirements alongside the hardware quantities on the PO.
Not Suitable If
Switch-powered phones or access points
SG350X-48 does not supply endpoint power. C1300-48P-4X is a current alternative with 48 Gigabit PoE access ports and four 10G SFP+ uplinks rather than copper/SFP+ combo uplinks.
Cisco support beyond October 2026
SG350X-48 reaches its last date of Cisco support on October 31, 2026. C1300-48T-4X is the current migration endpoint, following the discontinued CBS350-48T-4X-NA.
Native 10G access connections
SG350X-48 access ports stop at 1GbE. The 10G interfaces are uplinks, so this model cannot provide native 10G connections across its access ports.

What uplinks does the 48-port Gigabit stackable switch provide?
The 48-port Gigabit stackable switch provides two dedicated 10G SFP+ uplinks and two 10GBASE-T/SFP+ combo uplinks. Each combo uplink exposes copper and fiber connectors for one logical connection, with only one connector active at a time. Uplink interfaces support 1G and 10G operation.
How many switches can SG350X-48 stack together?
SG350X-48 supports a four-member hardware stack using 10G copper or fiber interconnects. Ring and chain topologies are available, with LAG supported for stacking links. Supported copper cables include SFP-H10GB-CU1M=, SFP-H10GB-CU3M= and SFP-H10GB-CU5M=; assign the interconnect interfaces when planning how many uplinks remain for other connections.
What routing does the 350X family support?
The 350X family supports static IPv4 and IPv6 routing, rather than dynamic routing protocols. IPv4 capacity reaches 990 static routes and 128 IP interfaces; IPv6 capacity reaches 245 static routes and 106 interfaces. These limits suit configured local routes, not a design requiring automatic route exchange.
What power supply does SG350X-48 use?
SG350X-48 uses an internal AC power supply accepting 100-240V AC, with no redundant internal supply option. Worst-case consumption reaches 51.6W at 110V. SG350X-48 does not deliver PoE to attached devices, so phones or access points need their own power arrangement rather than drawing power from the switch.
What rack space does SG350X-48 require?
SG350X-48 occupies one rack unit and measures 440 mm wide, 44 mm high and 257 mm deep. Its 3.73 kg weight and single fan should be included in rack placement planning. Confirm cabinet depth, ventilation and the intended mounting position before ordering the hardware.
Which 10G fiber transceivers are supported by SG350X-48?
SG350X-48 supports SFP-10G-SR= for 10G multimode fiber links and SFP-10G-LR= for 10G single-mode fiber links. SFP-10G-SR= supports distances from 26 m to 400 m, while SFP-10G-LR= supports 10 km. Match the transceiver, installed fiber and remote interface when specifying the link and its required distance.
What is the difference between SG350X-48 and SG350X-48P?
SG350X-48P supplies PoE+ on its access ports, while SG350X-48 provides data connectivity without endpoint power. SG350X-48P has a shared 382W PoE budget. SG350X-48 suits independently powered equipment, whereas SG350X-48P suits installations needing shared endpoint power; both models are discontinued and require lifecycle-aware purchasing.
What is the difference between SG350X-48 and SG350X-24?
SG350X-48 supplies 48 Gigabit access ports, whereas SG350X-24 supplies 24; both models are discontinued. Count connected devices and ports reserved for expansion before choosing existing-hardware spares. SG350X-48 suits larger endpoint inventories, while SG350X-24 suits smaller inventories requiring fewer physical access connections.
What is the difference between SG350X-48 and C1300-48T-4X?
C1300-48T-4X provides four 10G SFP+ uplinks, while SG350X-48 offers two dedicated SFP+ uplinks and two copper/SFP+ combo uplinks. The discontinued SG350X-48 supports buyers retaining copper uplink connections in existing installations; the current C1300-48T-4X suits orders specifying four fiber-format uplinks instead.
