SG350XG-48T is a managed Layer 2+ switch with 46 dedicated 10GBASE-T access ports and two fixed copper/SFP+ combo uplinks, providing 48 simultaneous network connections. Each shared uplink operates at 10G and uses copper or fiber, not both media at once. Non-PoE ports connect separately powered servers, storage, and other network devices without delivering endpoint power. The Cisco 350X Series places this copper-led configuration in a 1U rack-mount chassis for small-business networks. The discontinued SG350XG-24T has 24 network connections for a smaller legacy installation. A dedicated Gigabit out-of-band management port separates administrative access from endpoint traffic, while the RJ-45 console connection provides local access when commissioning or recovering the unit. Connection planning should cover endpoint media, administrative access, and the available rack position.

960 Gbps switching capacity supports wire-speed, nonblocking forwarding across the installed network interfaces. 714.24 Mpps forwarding performance is rated with 64-byte packets, allowing packet-size assumptions to be matched to the traffic profile rather than inferred from aggregate bandwidth. Static IPv4 routing supports local inter-VLAN paths, while static IPv6 routing handles the equivalent IPv6 design; dynamic routing is outside this feature set. SG350XG-48T combines 512 MB of DRAM, 256 MB of flash, and a 4 MB shared packet buffer, separating control-plane resources from packet storage. STP, RSTP, and MSTP support loop-control designs, while LACP aggregates compatible network links. Administrative options include browser-based HTTP/HTTPS, a scriptable CLI over SSH or Telnet, and SNMP integration with monitoring tools. A 32000-entry MAC table provides address-learning capacity across the configured VLANs. Within Cisco Small Business networking, ingress and egress access control policies allow traffic restrictions to be applied at the switch.

In a mid-sized data center, IT teams deploy the Cisco SG350XG-48T to aggregate 48 x 10GBase-T copper-connected application and database servers directly into a single switch. Dual 10G SFP+ combo ports link to the core router or spine fabric over fiber, while the dedicated Gigabit management port enables secure, out-of-band device provisioning and monitoring. Benefit: Consolidates server uplinks, slashes latency under 0.5 ms, and simplifies management—delivering up to 480 Gbps of non-blocking throughput with enterprise-grade visibility and control.
A university IT department uses the SG350XG-48T as a building-level backbone switch to aggregate dozens of Gigabit PoE+ edge switches and wireless APs via its 48 x 10GBase-T ports. Two 10G SFP+ combo ports carry high-speed, long-reach fiber links to the central core, and the Gigabit management port provides secure remote access for firmware updates and configuration backups. Benefit: Dramatically reduces network bottlenecks, ensures seamless roaming for 1 000+ students, and achieves campus-wide 10 Gbps connectivity with robust out-of-band management.
In a financial services virtualized environment, the SG350XG-48T connects hypervisor hosts to 48 x 10GBase-T ports for VM traffic and iSCSI storage, while its two SFP+ combo ports form redundant uplinks to a dedicated Fibre Channel over Ethernet (FCoE) storage switch. The separate Gigabit management port integrates with the centralized network management system for automated alerts and role-based access. Benefit: Enables sub-millisecond VM migration, enforces strict VLAN-based segmentation, and delivers non-disruptive failover—maximizing uptime and application performance.
When a server or storage refresh must retain twisted-pair cabling, 10GBASE-T links require Category 6a cable for runs reaching 100 m. Existing patching should be assessed alongside the equipment count, not treated as automatically reusable. Specify the cable category and measured run lengths before the PO.
When multiple sites need the same traffic classification policy, eight hardware queues provide a fixed basis for translating the existing policy into a replacement configuration. Inventory the queue assignments and any rate-limiting rules alongside the switch quantities. Specify the approved configuration baseline and staging requirements before the PO.
When replacement hardware will be staged before installation, the front USB Type A slot supports file and image handling, and dual-image support accommodates two software images. Include console access in the staging plan. Specify the approved software image, configuration file, and acceptance checks before releasing the purchase order.
Endpoint power over Ethernet
SG350XG-48T carries non-PoE copper ports and cannot power connected access points, phones, or cameras through their network cables. Endpoint power must be provided outside this switch.
Dedicated fiber uplinks beside copper ports
SG350XG-48T cannot provide 48 copper links plus two simultaneous fiber uplinks because both SFP+ connections share copper ports. Its replacement chain has no current successor.
Dynamic routing at the access edge
SG350XG-48T supports static routing rather than dynamic route exchange. Networks requiring automatically learned routes must place that function elsewhere; this model's replacement chain has no current successor.
Silent fanless operation
SG350XG-48T uses four fans and reaches 58.9 dB at 50°C. A requirement for silent, fanless operation is incompatible with this chassis.

SG350XG-48T identifies a 350X Series 10G copper model: SG350XG is the model group, 48 denotes its total network connections, and T identifies 10GBASE-T copper interfaces. The configuration includes two shared SFP+ connections and a separate Gigabit management port. The North American ordering variant is SG350XG-48T-K9-NA.
The Cisco 350X Series supports an HTTP/HTTPS web interface, full or menu CLI over SSH/Telnet or the local console, SNMP 1/2c/3, and Smart Network Application. Additional integration includes FindIT Network Manager, embedded FindIT Network Probe, FindIT Network Discovery Utility, and Active Advisor. These paths cover local configuration, scripted administration, and network-level monitoring.
No, SG350XG-48T is no longer supported by Cisco; its last date of support was June 30, 2025. End of sale was June 18, 2020, and software maintenance ended June 18, 2021. New sealed or refurbished stock does not restart these milestones, so this is a legacy hardware purchase.
ORM Systems offers SG350XG-48T new sealed with up to a 3-year extended warranty or certified refurbished with up to 1 year. Both have 30-day returns; terms apply. Cisco's limited lifetime hardware warranty ended June 30, 2025. Refurbished units are inspected and bench-tested, with firmware verified and configuration wiped to factory default.
No, SG350XG-48T does not provide PoE; its copper interfaces carry data only. Connected endpoints therefore need their own power source. A request for a 48-port switch should identify power delivery separately from data-port speed, because this model's 10GBASE-T connectivity does not imply endpoint-power capability.
No, SG350XG-48T cannot use all 48 copper connections and both SFP+ connections simultaneously. Each SFP+ connection shares an interface with one copper port, so the total remains 48 active network connections. When both fiber connections are used, 46 copper connections remain available for attached equipment.
The Cisco 350X Series supports four members in one hardware stack, with ring or chain topologies and 10G copper or fiber interconnects. Hybrid stacks can mix SG350X, SG350XG, and SX350X models. SFP-H10GB-CU1M=, SFP-H10GB-CU3M=, and SFP-H10GB-CU5M= provide 10G direct-attach cable options for compatible interfaces used as interconnects.
SG350XG-48T supports static IPv4 and IPv6 routing, with 990 static IPv4 routes and 128 IPv4 interfaces, plus 245 static IPv6 routes and 106 IPv6 interfaces. Physical ports, LAGs, VLAN interfaces, and loopback interfaces can host routing interfaces. Dynamic routing is outside this model's feature set.
SG350XG-48T provides 48 network connections, while SG350XG-24T provides 24; each includes two shared copper/SFP+ connections rather than additional dedicated fiber ports. Both models are discontinued, and Cisco support ended June 30, 2025. The distinction is legacy connection density: the larger model accommodates more attached equipment within one chassis.
SG350X-48P supplies PoE+ on 48 Gigabit access ports, while SG350XG-48T supplies no endpoint power and uses 10GBASE-T network interfaces. SG350X-48P is discontinued, so this is a legacy comparison. Powered Gigabit endpoints distinguish the former; separately powered 10G copper equipment distinguishes the latter.
SX350X-52 provides four dedicated 10G SFP+ uplinks beside 48 copper ports, whereas SG350XG-48T's two SFP+ connections share copper interfaces. SX350X-52 is discontinued, and its CBS350-48XT-4X-NA successor is also discontinued with no current migration product. The historical successor accommodates independent fiber uplinks rather than shared copper/fiber connections.
SG350XG-48T consumes a worst-case 272.6W at 110V or 258.2W at 220V from an internal universal AC supply accepting 100-240V. These figures describe switch system draw rather than endpoint PoE power. Electrical planning should use the applicable worst-case input draw and a power cord matching the installation region.
