SG550XG-48T-K9-EU provides 10 Gigabit copper connectivity in a managed, stackable 1U chassis for small business networks. The Layer 2+ design has 46 dedicated RJ-45 network ports and two fixed copper/SFP+ combo uplinks. Each combo connection supports one active medium, so selecting fiber disables its shared copper connection. This non-PoE model connects independently powered equipment rather than supplying endpoint power. The Cisco 550X Series supports network segmentation and local traffic forwarding without a modular uplink purchase. Compared with the discontinued SG550XG-24T-K9-EU, the copper configuration expands from 24 to 48 network connections. A dedicated Gigabit out-of-band management interface separates administrative connectivity from ordinary network links, while the shared uplink arrangement determines how many copper connections remain available when fiber is installed.

960 Gbps switching capacity provides a nonblocking fabric, while 714.24 Mpps forwarding applies to 64-byte packets. Static IPv4 and IPv6 routing, RIP v2, VRRP v2/v3 and PBR support local gateway and next-hop policies. Routing resources accommodate 7168 IPv4 routes, separate from the 32000-entry MAC table. SG550XG-48T-K9-EU combines 512 MB of DRAM with 256 MB of flash for control-plane operation and stored software, while a shared 4 MB packet buffer serves traffic across the ports. Textview CLI, HTTPS and SNMP provide command-line, browser and monitoring access. The SG550XG-48T uses four primary fans plus one redundant fan and accepts external RPS backup rather than a second internal supply. 264.4W worst-case consumption at 110V AC sets the higher electrical planning figure; the corresponding 220V AC figure is 255.8W. These voltage-specific figures provide the basis for sizing the rack's electrical allocation.
ORM Systems offers SG550XG-48T-K9-EU new sealed with up to a 3-year extended warranty or certified refurbished with up to 1 year, plus 30-day returns on either condition, terms apply; Cisco's original limited lifetime hardware warranty and service ended June 30, 2025. Refurbished units are inspected and bench-tested for power-on and POST, every port linking at rated speed, optics bay recognition, PSU status, fan status and clean boot; firmware is verified and configurations are wiped to factory default. Specify condition, SFP-10G-SR or SFP-10G-LR requirements, and quantities on the PO. Enterprise and volume orders are accepted by PO, with Net-30 for government and RMA with advance replacement in the UK, EU, US and MEA.

When an existing server or storage rack moves to copper 10G links, cable qualification is part of the hardware order. Category 6a supports connections to 100 m. Audit the installed runs and far-end interfaces, then specify replacement patching and required connection media before the PO.
When an installed 550X stack needs another member, the mix of existing models determines the connection plan. Hybrid stacks can combine SF550X, SG550X, SG550XG and SX550X hardware, using ring or chain arrangements. Reserve the inter-switch links and specify the connection layout before ordering the additional unit.
When a retained business network places VLAN gateways on the switch, interface scale needs a separate check from physical connectivity. The hardware supports 256 IP interfaces and 1792 IPv6 static routes. Compare the existing gateway configuration and IPv6 route inventory with these limits before specifying the replacement quantity.
Switch-powered phones and wireless access points
SG550XG-48T-K9-EU carries data-only copper ports and supplies no PoE output. Endpoint power must come from equipment outside this switch.
Simultaneous copper and fiber on combo ports
SG550XG-48T-K9-EU allows only one active medium per combo connection. The SFP+ cages share their connections with copper ports rather than adding separate interfaces.
Active Cisco service coverage
SG550XG-48T-K9-EU passed its last date of support on June 30, 2025. Cisco service is unavailable, regardless of whether stock is new sealed or refurbished.

SG550XG-48T-K9-EU identifies the EU regional 48-port copper configuration in the 550X stackable managed family. The SG550XG models provide 10 Gigabit connectivity, while 48T identifies the copper-port configuration. EU is a regional ordering suffix also used in markets including Russia, Israel and the UAE; two copper connections share SFP+ media.
SG550XG-48T-K9-EU provides 48 network connections through 46 dedicated copper ports and two copper/SFP+ combo connections. Each combo connection uses copper or fiber, not both simultaneously. Activating both SFP+ cages leaves the 46 dedicated copper connections available, while the separate Gigabit management interface remains available for administration.
The Cisco 550X Series supports HTTP/HTTPS web interfaces, Textview CLI through console, SSH or Telnet, and SNMP v1/v2c/v3. Additional management paths include Smart Network Application, FindIT Network Manager with an embedded Probe, FindIT Network Discovery Utility, and Active Advisor. The browser interface offers simple and advanced operating modes.
SG550XG-48T delivers 960 Gbps switching capacity and 714.24 Mpps forwarding for 64-byte packets. A shared 4 MB packet buffer serves traffic across the ports, and the MAC table holds 32000 entries. These are individual-switch resources, so a stack design must also account for the Ethernet links allocated to interconnection.
SFP-10G-SR and SFP-10G-LR are supported fiber options for SG550XG-48T-K9-EU, serving multimode and single-mode links respectively. SFP-H10GB-CU1M, SFP-H10GB-CU3M and SFP-H10GB-CU5M provide direct-attach copper alternatives. Match the selected part to the far-end interface, installed media and connection distance, and specify the required quantities separately from the switch.
Yes, Cisco 550X Series switches support hardware stacks of eight members using 10G copper or fiber interconnections. Ring and chain topologies are available, and hybrid stacks can mix SF550X, SG550X, SG550XG and SX550X models. Allocate the inter-switch links before counting the connections available for endpoints and upstream equipment.
SG550XG-48T-K9-EU supports static IPv4 and IPv6 routing, RIP v2, VRRP v2/v3 and PBR. Capacity reaches 7168 IPv4 routes and 256 IP interfaces, while IPv6 static routing supports 1792 routes. Size the routing interfaces and route inventory separately from physical port density when retaining an existing routed-edge configuration.
No, SG550XG-48T-K9-EU does not have dual internal redundant power supplies. Power redundancy uses the external RPS connection instead. The internal universal supply accepts 100-240V AC at 47-63 Hz; specify any external backup equipment and its connection requirements separately when the retained installation needs redundant power input.
Yes, SG550XG-48T-K9-EU is a full-width Rack-Mount 1U switch measuring 440 mm wide, 44 mm high and 450 mm deep, with a weight of 7.43 kg. The original package includes a mounting kit and console cable. Confirm both accessories when specifying a refurbished unit for rack installation.
SG550XG-48T-K9-EU is discontinued, and Cisco service ended on June 30, 2025. The end-of-sale date was June 18, 2020, followed by the end of software maintenance releases on June 18, 2021. New sealed inventory does not restart these milestones or restore eligibility for Cisco service after the final support date.
SG550XG-48T-K9-EU was replaced by SX550X-52-K9-EU, which was subsequently replaced by CBS350-48XT-4X-EU; both successors are discontinued, and no current migration product continues that chain. Replacement planning therefore requires a separate hardware selection rather than treating either historical successor as a current model available for a new supported deployment.
SG550X-48P-K9-EU supplies PoE+ with a shared 382W budget, while SG550XG-48T-K9-EU supplies no PoE. Both models are discontinued. The PoE model addresses powered-endpoint requirements in a retained installation; the non-PoE model serves data connections to equipment that receives its operating power from another source.
SG550XG-48T-K9-EU has 48 network connections, while SG550XG-24T-K9-EU has 24; both configurations include shared copper/SFP+ connections. Both models are discontinued. The larger model suits a retained installation needing more copper terminations, while the smaller model fits a lower-density spare requirement within the same legacy family.
SG550XG-48T-K9-EU is copper-based, while SG550XG-24F-K9-EU is fiber-oriented with copper available through shared combo connections. Both models are discontinued. Existing racks terminated in twisted-pair cabling align with the copper model; retained aggregation links terminated in SFP+ fiber align with the fiber model's connection arrangement.
ORM offers SG550XG-48T-K9-EU new sealed or certified refurbished. New orders carry up to a 3-year extended warranty; certified refurbished orders carry up to 1 year. Both conditions have 30-day returns, terms apply. Cisco's original limited lifetime hardware warranty and service ended June 30, 2025; ORM coverage is separate.
