SX550X-24FT-K9-EU combines 12 dedicated 10GBASE-T copper ports with 12 dedicated 10G SFP+ uplinks in a managed, rack-mount 1U switch. The non-PoE configuration connects servers and network storage over copper while aggregating fiber-connected access switches. Layer 2+ functionality adds local routing to the switching configuration. Within the Cisco 550X Series, the balanced copper and fiber layout avoids shared combo connections between the two media. The discontinued SX550X-16FT-K9-EU uses eight copper ports and eight dedicated SFP+ ports instead. This 24-port 10 Gigabit Ethernet stackable managed switch serves small and medium business aggregation where connected devices receive power separately. Fixed uplinks keep the network connections on the base chassis rather than requiring an additional uplink card.

480 Gbps switching capacity supports nonblocking forwarding between the installed network interfaces. 240 Mpps forwarding at 64-byte packets provides the packet-processing figure for traffic planning rather than relying on port speed alone. Static routing and RIP v2 carry internal IPv4 traffic, while VRRP v2/v3 provides default-gateway redundancy and PBR selects next hops through policy. SX550X-24FT-K9-EU has 512 MB of DRAM and 256 MB of flash for its switching software and stored images. A shared 3 MB packet buffer serves all ports instead of assigning a dedicated buffer to each interface. The 32000-entry MAC table accommodates learned Ethernet addresses, and the 7168-route IPv4 total bounds routed network plans. STP, RSTP, MSTP, and LACP handle loop control and link aggregation. The separate Gigabit out-of-band management port provides a dedicated administration connection. Cooling uses two operating fans with one redundant fan; the chassis is not fanless.
SX550X-24FT-K9-EU is available new sealed or certified refurbished; ORM's new-unit extended warranty runs up to 3 years, certified refurbished coverage runs up to 1 year, and both conditions have 30-day returns with terms applying. Certified refurbished units are inspected and bench-tested for power-on and POST, clean boot, rated-speed port links, optics bay recognition, PSU status, and fan status, with firmware verified and configuration wiped to factory default. Cisco's original limited lifetime hardware warranty is bounded by July 31, 2027, subject to eligibility; specify condition, quantity, and required connection accessories on the purchase order. ORM Systems accepts POs, offers Net-30 for government, and supports enterprise and volume orders across UK, EU, US, and MEA stock and RMA regions, including RMA with advance replacement.

When inter-VLAN communication must move off an upstream router, the 550X configuration allows 256 IP interfaces. Map each VLAN, routed physical port, and link aggregation interface into that limit, then verify the planned addressing and routing configuration before specifying the switch quantity on the purchase order.
When a multi-site purchase standardizes the regional ordering code, SX550X-24FT-K9-EU uses the EU country/region group, which also covers markets including Israel, UAE, Turkey, and South Africa. Regional naming is not limited to EU destinations. Confirm destination, power-cord requirements, mounting hardware, and console-cable inclusion before releasing the site-by-site purchase order.
When switches are staged before a scheduled change, the front USB Type-A connection supports local firmware and configuration transfers. Two software images provide an alternate stored image for upgrade handling. Define the required firmware, saved configuration, and image-selection procedure before ordering units for the staging batch.
PoE power for connected endpoints
SX550X-24FT-K9-EU provides network connectivity but no PoE output. Requirements for the switch to power phones, cameras, or wireless access points exceed this model's capabilities.
Native 40G or faster uplinks
Network connections top out at 10 Gigabit Ethernet. The fixed SFP+ uplinks cannot provide native 40G links, and the chassis has no removable uplink bay for higher-speed expansion.
Cisco support beyond July 2027
Cisco service ends July 31, 2027. C1300-24XTS is the current successor, retaining the 12-port copper and 12-port SFP+ configuration for migration purchases.

SX550X-24FT-K9-EU identifies a 550X managed 10 Gigabit Ethernet switch with 24 network connections. The SX550X model group supplies 10G connectivity; the 24FT configuration pairs 12 copper ports with 12 dedicated SFP+ ports. EU is the country/region ordering suffix covering the EU and additional designated markets.
The Cisco 550X Series supports HTTP/HTTPS web management, Textview CLI through the console or SSH/Telnet, and SNMP v1/v2c/v3. Network-level tools include Smart Network Application, FindIT Network Manager with an embedded FindIT Network Probe, and Active Advisor. FindIT Network Discovery Utility provides browser-based discovery, while a dedicated Gigabit port supports out-of-band administration.
Yes, SX550X-24FT-K9-EU reached end of sale July 30, 2022, and its last date of support is July 31, 2027. Software maintenance releases ended July 30, 2023. The original replacement, CBS350-24XTS-EU, is also discontinued; the migration chain now ends at C1300-24XTS rather than the intermediate Business 350 model.
ORM Systems offers SX550X-24FT-K9-EU new sealed with up to a 3-year extended warranty or certified refurbished with up to 1 year. Both conditions include 30-day returns; terms apply. Cisco's original limited lifetime hardware warranty is separate, applies to eligible hardware, and cannot extend service beyond July 31, 2027.
The Cisco 550X Series supports SFP-10G-SR for 10G multimode fiber and SFP-10G-LR for 10G single-mode fiber. SFP-10G-LR reaches 10 km; SFP-H10GB-CU1M supplies a 1 m direct-attach copper connection. Specify the exact accessory PID and compatible fiber or cable length rather than ordering by connector shape alone.
Yes, SX550X-24FT-K9-EU supports hardware stacks of eight members, including mixed SF550X, SG550X, SG550XG, and SX550X models. Stacking uses 10G copper or fiber network interfaces rather than separate stack-only ports. SFP-H10GB-CU1M, SFP-H10GB-CU3M, and SFP-H10GB-CU5M provide supported direct-attach cable options; reserve the selected interfaces for stack links.
The Cisco 550X Series supports IPv4 static routing, RIP v2, PBR, and VRRP v2/v3, placing this configuration in Layer 2+. The IPv4 route total is 7168, with 256 IP interfaces. IPv6 static routing supports 1792 routes and 256 IPv6 interfaces; size each address family separately before ordering.
No, SX550X-24FT-K9-EU does not ship with two internal power modules; power redundancy uses an external RPS2300 connection. The internal universal AC supply accepts 100-240V AC. External backup power is separate from the built-in supply and does not make the chassis an internally redundant, hot-swappable power-supply system.
The 24-port copper and fiber 550X switch mounts in a standard rack as a 1U switch, and the original package includes a mounting kit. Dimensions are 440 mm wide, 44 mm high, and 350 mm deep; weight is 4.84 kg. Allow for the rear power connection when checking rack space.
SG550X-24P-K9-EU supplies a shared 195W PoE budget, while SX550X-24FT-K9-EU supplies no endpoint power. Both models are discontinued. The comparison is relevant to existing 550X installations: SG550X-24P-K9-EU serves powered access endpoints, whereas SX550X-24FT-K9-EU serves connections whose connected devices already have separate power.
SX550X-24FT-K9-EU has 12 copper ports and 12 dedicated SFP+ ports, compared with eight of each on SX550X-16FT-K9-EU. Both switches use fixed 10G connections and are discontinued. Existing installations needing the larger balanced port layout match the 24FT configuration; installations with fewer copper and fiber connections match the 16FT configuration.
C1300-24XTS is the current successor, while SX550X-24FT-K9-EU reached end of sale July 30, 2022. The migration chain passes through CBS350-24XTS-EU, which is also discontinued. SX550X-24FT-K9-EU is relevant to matching existing hardware; C1300-24XTS is the migration choice for buyers establishing a current hardware standard rather than extending the discontinued range.
