SG350XG-48T-K9-EU is a Layer 2+ managed switch delivering 10 Gigabit Ethernet over copper for small-business networks. Its 46 dedicated RJ-45 access ports sit alongside two fixed 10G copper/SFP+ combo uplinks; each combo interface uses copper or fiber, not both simultaneously. The 48-port 10GBASE-T stackable switch occupies a 1U rack position and connects separately powered servers, storage, and workstations without providing PoE. The Cisco 350X Series combines managed Ethernet switching with local routing and hardware stacking. The discontinued SG350XG-24T-K9-EU is the lower-density sibling, offering 24 logical 10G ports rather than 48. A dedicated Gigabit out-of-band management port provides a separate connection for administrative access instead of requiring management traffic to share a regular network port.

960 Gbps switching capacity provides a nonblocking fabric for active network connections. 714.24 Mpps forwarding at 64-byte packets defines the small-packet processing rate. 990 static IPv4 routes and 245 static IPv6 routes support locally configured paths between subnets; dynamic routing is not included. SG350XG-48T-K9-EU pairs 512 MB of DRAM with 256 MB of flash for runtime operation and persistent software storage. Shared 4 MB packet buffering serves traffic across the ports rather than reserving a separate buffer for each connection. The address table accommodates 32000 MAC entries, while 4094 active VLANs support traffic segmentation. STP/RSTP/MSTP provide spanning-tree control, and LACP supports negotiated link aggregation. DHCP snooping and Dynamic ARP Inspection check address-related traffic against learned or configured bindings. 272.6W worst-case consumption provides the maximum electrical load for power planning; consumption at 220V is 258.2W. Four fans cool the chassis across its 0°C to 50°C operating range, so cabinet ventilation remains part of installation planning.
ORM Systems offers SG350XG-48T-K9-EU new sealed or certified refurbished, with up to a 3-year extended warranty on new units and up to 1 year on certified refurbished units. Refurbished units are inspected and bench-tested for power-on and POST, every port linking at rated speed, clean boot, optics bay recognition, PSU status, and fan status; firmware is verified and configurations are wiped to factory default. Specify condition, quantity, and regional cord requirements on the PO; every condition includes 30-day returns, terms apply, while Cisco's original limited lifetime hardware warranty and service ended June 30, 2025. Enterprise and volume orders support PO acceptance, Net-30 for government, and RMA with advance replacement across UK, EU, US, and MEA.

When an existing installation is retaining copper cabling for server or workstation connections, the cable plant belongs in the purchase review alongside the chassis. Category 6a supports 10 Gigabit Ethernet over runs reaching 100 m. Confirm cable category, termination quality, and patch-lead requirements before specifying the order.
When a legacy switch stack needs another member, SG350X, SG350XG, and SX350X can share a hybrid stack rather than requiring identical models. Ring and chain arrangements are supported. Identify the existing members and intended interconnect topology, then specify the additional member and stacking connections on the purchase order.
When replacement hardware is being staged before a change window, two software images support image preparation, and the front USB Type A slot supports file and image management. Identify the intended software image, configuration transfer method, and clean-boot checks, then confirm the staging checklist before releasing the purchase order.
Power delivery to connected endpoints
SG350XG-48T-K9-EU does not supply PoE on its network ports. Powered phones, cameras, and access points require separate power sources or PoE-capable switching hardware.
Independent fiber uplinks beside all copper connections
SG350XG-48T-K9-EU has two shared copper/SFP+ combo interfaces, not two additional fiber ports. Selecting fiber on either interface disables its corresponding copper connection.
Stacks larger than four members
350X hardware stacking stops at four switches in one system. A purchase requiring additional members within the same hardware stack exceeds this model's supported stacking limit.

SG350XG-48T-K9-EU identifies the regional ordering form of a 48-port 10GBASE-T stackable managed switch. SG350XG identifies the 10 Gigabit switch family, 48 denotes port count, T identifies copper connectivity, and EU is the country/region suffix used for the EU and several additional markets.
SG350XG-48T-K9-EU supports HTTP/HTTPS web management, console and SSH/Telnet CLI access, SNMP, Smart Network Application, Cisco FindIT Network Manager, and Active Advisor. Full and menu CLI modes are available. The embedded FindIT Network Probe and Network Plug and Play agent provide additional discovery and provisioning integration.
SG350XG-48T-K9-EU is discontinued, and Cisco service ended on June 30, 2025. End of sale occurred on June 18, 2020, and software maintenance ended on June 18, 2021. The switch is beyond Cisco's last date of support, rather than merely being unavailable for new Cisco orders.
ORM Systems offers SG350XG-48T-K9-EU new sealed or certified refurbished, with up to a 3-year extended warranty on new units and up to 1 year on certified refurbished units. Both conditions have 30-day returns; terms apply. Cisco's original limited lifetime hardware warranty ended with Cisco service on June 30, 2025.
No, SG350XG-48T-K9-EU has two SFP+ interfaces shared with two copper interfaces, not two additional independent ports. The chassis provides 46 dedicated copper connections plus two combo connections. Each combo connection operates through either its copper connector or its SFP+ cage, with only one medium active at a time.
350X hardware stacking supports four members managed as one system, including mixed SG350X, SG350XG, and SX350X switches. Ring and chain topologies are supported through 10G copper or fiber connections. Supported direct-attach cable options include SFP-H10GB-CU1M=, SFP-H10GB-CU3M=, and SFP-H10GB-CU5M= for matching interconnect distances.
Yes, SG350XG-48T-K9-EU supports static IPv4 and IPv6 routing between configured interfaces. IPv4 capacity reaches 990 static routes and 128 IP interfaces; IPv6 capacity reaches 245 static routes and 106 IPv6 interfaces. The routing feature set uses manually defined paths rather than dynamic routing protocols.
SG350XG-48T-K9-EU uses an internal universal AC supply accepting 100-240V AC at 47-63 Hz. Worst-case consumption is 272.6W at 110V or 258.2W at 220V. The EU regional ordering suffix does not restrict the electrical input to 220V; the destination still determines the required power cord.
The 350X 48-port 10GBASE-T switch is rack-mountable in 1U but is not fanless; four fans cool the chassis. Dimensions are 440 mm wide, 44 mm high, and 450 mm deep, with a weight of 7.43 kg. The operating temperature range is 0°C to 50°C.
SG350XG-48T-K9-EU supplies no PoE, whereas discontinued SG350X-48P-K9-EU provides PoE+ with a shared 382W budget. Power allocations on the latter remain subject to that total budget. For legacy replacements, the first suits separately powered connections; the second suits endpoints requiring power through their Ethernet connections. Both models are discontinued.
SG350XG-48T-K9-EU provides 48 logical 10G connections, while discontinued SG350XG-24T-K9-EU provides 24. Both use two copper/SFP+ combo interfaces within their respective totals. For matching legacy hardware, the larger model suits higher connection counts, while the smaller model suits installations requiring fewer copper connections. Both are discontinued.
SG350XG-48T-K9-EU shares two SFP+ interfaces with copper ports, whereas discontinued SX350X-52-K9-EU has four dedicated SFP+ interfaces alongside 48 copper ports. For legacy matching, the former suits shared copper-or-fiber connections; the latter suits installations requiring independent fiber connections without surrendering copper ports. Neither model is a current successor.
SG350XG-48T-K9-EU was replaced by SX350X-52-K9-EU, now discontinued; the chain then reaches CBS350-48XT-4X-EU, also discontinued, with no current successor. SX350X-52-K9-EU reached end of sale on July 30, 2022. CBS350-48XT-4X-EU reached end of sale on October 29, 2024, so neither should be treated as a current migration destination.
350X Stackable Managed Switches support STP/RSTP/MSTP, LACP, DHCP snooping, and Dynamic ARP Inspection for loop control, link aggregation, and address checks. The series also provides VLAN segmentation, port security, and traffic mirroring. These features require configuration appropriate to the connected network rather than operating as an unmanaged forwarding device.
