SG550XG-24T-K9 is a managed Layer 2+ 10 Gigabit Ethernet switch for small-business aggregation, with 22 dedicated copper network ports and two fixed 10G copper/SFP+ combo uplinks in a rack-mount 1U chassis. Each combo connection uses one medium at a time, so a fiber uplink displaces its paired copper connection rather than adding another active port. The non-PoE configuration connects equipment that receives power independently of its network connection. Within the Cisco 550X Series, the discontinued SG550XG-48T-K9-NA has 46 dedicated copper network ports while retaining two combo uplinks, distinguishing the higher-density model from this configuration. Both 1G and 10G link speeds are supported on the copper and SFP+ connections when matching interfaces to existing network equipment.

480 Gbps switching capacity provides wire-speed, nonblocking bandwidth across the active connections. 357.12 Mpps forwarding at 64-byte packets specifies the small-packet processing limit separately from aggregate bandwidth. Static routing and RIP v2 support inter-VLAN traffic, while VRRP v2/v3 provides gateway redundancy and PBR selects next hops using access-control rules. 7168 IPv4 routes define the routing-table ceiling for connected networks. SG550XG-24T-K9 carries 512 MB of DRAM and 256 MB of flash for runtime operation and firmware storage. Its 32000-entry MAC table sets the address-learning scale for attached devices. A shared 2 MB packet buffer serves all ports rather than dedicating that capacity to each interface. STP/RSTP/MSTP controls Layer 2 loops, and LACP builds aggregated links. 4094 active VLANs provide the segmentation ceiling for workgroups and services. Textview CLI and browser-based configuration provide administration, while SNMP integrates monitoring with a network management station. sFlow exports traffic samples and RSPAN mirrors traffic to a remote analysis port.
Specify SG550XG-24T-K9 as new sealed or certified refurbished, with ORM warranties of up to 3-year extended coverage for new units or up to 1 year for certified refurbished units. Refurbished units are inspected and bench-tested for rated-speed links on every port and optics bay recognition, with firmware verified and configuration wiped to factory default. Cisco's limited lifetime hardware warranty and service ended June 30, 2025; ORM returns cover 30 days on every condition, with terms applying. Enterprise and volume POs are accepted, with Net-30 for government, RMA with advance replacement, and regional stock/RMA across the UK, EU, US, and MEA.

When additional workgroups require routed separation, interface scale matters alongside physical connectivity. The switch supports 256 IP interfaces and 1792 IPv6 static routes, with routed interfaces available on physical ports, VLANs, link aggregations, or loopbacks. Specify the interface plan and IPv6 route requirements before placing the purchase order.
When extending an existing hardware stack, ring or chain topology determines the interconnect plan. SF550X, SG550X, SG550XG, and SX550X models can share a stack, and SFP-H10GB-CU3M provides a 3 m direct-attach copper option. Confirm the stack partners, topology, and interconnect quantities before ordering the additional unit.
When replacement hardware must be staged separately from production traffic, a dedicated Gigabit out-of-band port provides a separate management connection. Local console access and USB image/configuration transfer are also available. Specify the staging access method and configuration handoff before placing the purchase order.
Power delivery to connected endpoints
SG550XG-24T-K9 supplies no PoE. C1300-24P-4X provides powered access, but its 24 access ports are Gigabit rather than 10 Gigabit, alongside four 10G SFP+ uplinks.
New hardware requiring ongoing Cisco service
Cisco service for SG550XG-24T-K9 ended June 30, 2025. C1300-24XT is the current endpoint of the replacement chain for buyers specifying a supported migration target.
More than two simultaneous fiber connections
SG550XG-24T-K9 has only two shared SFP+ connections. C1300-24XT provides four shared 10G SFP+ connections within a 24-port 10G copper configuration, not four additional dedicated fiber ports.

SG550XG-24T-K9 identifies the 550X 24-port 10GBASE-T copper model, with two copper connections shared with SFP+ slots. SG550XG identifies the model group, 24 identifies the total network-port count, and T identifies copper connectivity. The complete North American ordering form is SG550XG-24T-K9-NA; its regional ending does not add ports.
SG550XG-24T-K9 supports a web UI, Textview CLI over console, SSH or Telnet, SNMP, Smart Network Application, FindIT Network Manager with embedded Probe, and Active Advisor. Browser access uses HTTP/HTTPS. FindIT Network Discovery Utility discovers devices and displays inventory information, while the dedicated Gigabit port provides an out-of-band management connection.
SG550XG-24T-K9 is discontinued: end of sale was June 18, 2020, software maintenance ended June 18, 2021, and Cisco support ended June 30, 2025. The North American replacement chain passes through discontinued SX550X-24-K9-NA and discontinued CBS350-24XT-NA to C1300-24XT. Existing units therefore require an independently planned maintenance arrangement.
ORM Systems offers SG550XG-24T-K9 new sealed or certified refurbished, with up to a 3-year extended ORM warranty on new units and up to 1 year on refurbished units. Returns are 30 days for either condition; terms apply. Cisco's original limited lifetime hardware warranty and service ended June 30, 2025.
No, SG550XG-24T-K9 supplies no PoE power through its network ports. Connected equipment must receive power elsewhere. C1300-24P-4X offers powered access with 24 Gigabit access ports and four 10G SFP+ uplinks, so that alternative also changes endpoint link speed from 10 Gigabit to Gigabit rather than providing equivalent powered connections.
SG550XG-24T-K9 has two 10G SFP+ combo connections, each sharing an interface with a copper port. Only one medium per combo connection can be active. SFP-10G-SR supports multimode fiber, and SFP-10G-LR supports single-mode fiber. Select optics to match the fiber path and remote interface rather than treating both connectors as separate ports.
SG550XG-24T-K9 supports hardware stacks of eight members using standard 10G copper or fiber connections. Ring and chain topologies are available, and SF550X, SG550X, SG550XG, and SX550X models can mix in the same stack. SFP-H10GB-CU1M, SFP-H10GB-CU3M, and SFP-H10GB-CU5M provide direct-attach copper options of 1 m, 3 m, and 5 m, respectively.
SG550XG-24T-K9 provides static routing, RIP v2, VRRP v2/v3, and PBR, with a total IPv4 route scale of 7168 routes. IPv6 static routing supports 1792 routes. Routed interfaces can use physical ports, link aggregations, VLAN interfaces, or loopbacks, so the interface and route plan must fit those limits.
The SG550XG-24T 24-port 10GBASE-T model occupies 1U and measures 440 mm wide, 44 mm high, and 450 mm deep, with a weight of 6.38 kg. Cooling uses four fans plus one redundant fan. Operation is rated from 0°C to 50°C, and a mounting kit is included with the original package.
The SG550XG-24T copper model accepts 100–240V AC through its internal supply and has an external redundant-power connection. Worst-case consumption is 143.9W at 110V AC and 142.9W at 220V AC. Power redundancy is external rather than a second hot-swappable internal supply, so the rear connection is not an additional PSU bay.
SG550XG-24T-K9 is non-PoE, whereas SG550X-24P-K9-NA provides PoE+ with a 195W budget. The powered model also has Gigabit access rather than 10 Gigabit access. Both models are discontinued: the first matches an existing 10G copper installation, while the second matches an existing powered Gigabit installation requiring like-for-like maintenance.
SG550XG-48T-K9-NA has 48 total 10G copper network connections, compared with 24 on SG550XG-24T-K9; both share two copper connections with SFP+ slots. Both models are discontinued. The smaller model matches maintenance requirements for an existing 24-port installation, while the larger model matches an existing installation needing the higher copper-port density.
C1300-24XT provides four shared 10G SFP+ connections, whereas SG550XG-24T-K9 provides two; both have 24-port 10G copper configurations. SG550XG-24T-K9 is discontinued and belongs in existing-installation maintenance planning. C1300-24XT is the current endpoint of the replacement chain for buyers migrating to new hardware, with four shared fiber connections rather than additional dedicated fiber ports.
The 550X series supports STP/RSTP/MSTP, LACP, and 4094 active VLANs for loop control, link aggregation, and segmentation. LACP permits 32 groups with eight active ports per group, while sFlow and RSPAN support traffic observation. The SG550XG-24T model has a shared 2 MB packet buffer across its ports.
