SG250X-24P-K9-EU combines 24 Gigabit PoE+ access ports with mixed-media 10G uplinks in a Layer 2+ smart-managed switch. Two fixed 10GBASE-T ports and two fixed SFP+ cages provide copper and fiber connections without a removable uplink card. The 1U rack-mount configuration belongs to Cisco 250 Series Smart Switches and serves small-business networks connecting IP phones, wireless access points, and video cameras. Supported powered endpoints receive data and power through their access connections, while the uplink interfaces accommodate different cabling requirements. The discontinued SG250X-24-K9-EU sibling retains the same access-port density and uplink arrangement but does not supply endpoint power. This Gigabit PoE smart switch with 10G uplinks combines powered endpoint connectivity with local inter-VLAN forwarding rather than dynamic route learning.

128 Gbps switching capacity accommodates the fixed port set without blocking, while 95.23 Mpps forwarding applies to 64-byte packets. 195W of shared PoE output requires endpoint allocation rather than maximum draw on every powered port. 32 IPv4 static routes define the routing ceiling; dynamic route learning is not provided. STP/RSTP/MSTP and LACP control bridged paths and aggregated links, while RADIUS and port security govern access. SG250X-24P-K9-EU carries 512 MB of DRAM and 256 MB of flash for operation and image storage, with a 12 Mb packet buffer shared across ports. The 8000-entry MAC table bounds learned-address scale. HTTP/HTTPS configuration, scriptable CLI access, and SNMPv1/v2c/v3 provide individual-device administration; Smart Network Application and FindIT Network Manager extend network-level management. Ingress and egress policies can use 512 ACL rules, and eight hardware queues handle traffic priority assignments. 260.1W maximum draw including PoE at 110V sets the electrical planning reference. Two fans provide active cooling, so equipment placement must allow airflow.
ORM Systems supplies SG250X-24P-K9-EU new sealed or certified refurbished, with up to a 3-year extended warranty on new units and up to 1 year on refurbished units; returns are 30 days in either condition, with terms applying. Refurbished units are inspected and bench-tested, including PoE output under load on every powered port and optics bay recognition, then firmware verified and wiped to factory default. Specify condition, quantity, and accessories on the PO, keeping Cisco's limited lifetime hardware warranty separate: Cisco service ends October 31, 2026, and original fan/power-supply coverage is 1 year. Enterprise and volume orders support PO acceptance, Net-30 for government, and RMA with advance replacement across UK, EU, US, and MEA stock/RMA regions.

Branches separating workgroups with SG250X-24P-K9-EU can place routed interfaces on physical ports, LAGs, VLAN interfaces, or loopbacks, with a ceiling of 16 IP interfaces. That limit differs from bridged VLAN capacity. Map which segments need a local gateway, and verify the complete interface plan before adding hardware to the purchase order.
Sites adding multicast receivers on SG250X-24P-K9-EU can use IGMP snooping versions 1, 2, and 3 with 255 multicast groups. An IGMP querier maintains the snooping domain when a multicast router is absent. Inventory the required groups and identify the querier device before ordering hardware for the endpoint rollout.
Teams staging SG250X-24P-K9-EU firmware changes can retain two software images and transfer updates by web browser, TFTP, or SCP over SSH. The front USB Type-A slot also supports image and configuration transfer. Specify the delivered image and configuration, and test the chosen transfer path before authorizing staged units for purchase.
Full-power PoE+ on every access port
The shared 195W budget cannot deliver 30W simultaneously to all 24 powered ports. Endpoint allocations must fit the total budget, regardless of how many devices are connected.
Four 10G SFP+ fiber uplinks
SG250X-24P-K9-EU has two SFP+ uplinks; its other two 10G uplinks are copper. C1200-24P-4X provides four 10G SFP+ uplinks while retaining 24 Gigabit PoE access ports.
Cisco support after October 2026
Cisco service for SG250X-24P-K9-EU ends October 31, 2026. C1200-24P-4X is the current migration endpoint for purchases that exclude hardware reaching its final Cisco support date.

SG250X-24P-K9-EU identifies a Cisco 250 Series Gigabit PoE+ smart switch with 10G uplinks. SG250X denotes that model group, 24 identifies the access-port count, and P identifies PoE+. EU is the regional ordering suffix for the EU and additional designated markets; the hardware includes fixed copper and SFP+ uplinks.
Cisco 250 Series Smart Switches support HTTP/HTTPS web interfaces, full or menu-based CLI over SSH or Telnet, SNMPv1/v2c/v3, Smart Network Application, FindIT Network Manager with embedded FindIT Network Probe, and Cisco Active Advisor. FindIT Network Discovery assists discovery; Cisco Network Plug and Play provides provisioning through Cisco PnP Connect.
SG250X-24P-K9-EU is discontinued: end of sale was October 30, 2021, and Cisco support ends October 31, 2026. Software maintenance ended October 30, 2022. The original replacement, CBS250-24P-4X-EU, is also discontinued; C1200-24P-4X is the current migration endpoint rather than the retired intermediate model.
ORM Systems offers SG250X-24P-K9-EU new sealed or certified refurbished. New units carry up to a 3-year extended ORM warranty; refurbished units carry up to 1 year. Returns are 30 days for either condition; terms apply. Cisco's original limited lifetime hardware warranty has 1-year fan/PSU coverage, with service ending October 31, 2026.
SG250X-24P-K9-EU supplies a shared 195W across 24 PoE+ ports, with a 30W individual-port limit. That ceiling does not mean every port can draw its maximum simultaneously. Size allocations from each endpoint's required power, and include every powered device in the load plan before deciding how many endpoints the order will serve.
SG250X-24P-K9-EU has four fixed 10G uplinks: two 10GBASE-T copper ports and two SFP+ cages. SFP-10G-SR supports multimode fiber, while SFP-10G-LR supports single-mode fiber links up to 10 km. SFP-H10GB-CU1M is a 1 m copper direct-attach option; select media to match the peer interface and installed cabling.
SG250X-24P-K9-EU provides static routing with 32 IPv4 routes and 16 IP interfaces, corresponding to Layer 2+ capability rather than dynamic route learning. Routed interfaces can be physical ports, LAGs, VLAN interfaces, or loopbacks. Keep the route plan and interface plan within those limits before specifying local inter-VLAN routing.
SG250X-24P-K9-EU is a 1U rack-mount switch measuring 440 mm wide, 44 mm high, and 257 mm deep. The 3.86 kg unit includes a mounting kit in its base package. Desktop placement and wall mounting are also supported; confirm the chosen mounting arrangement and required components before finalizing the purchase order.
SG250X-24P-K9-EU uses an internal 100–240V AC supply, with maximum consumption including PoE of 260.1W at 110V. The corresponding 220V figure is 257.1W. AC powers the chassis; its uplinks are not PoE-powered-device inputs. Specify the site's power-cord requirements rather than ordering an external power adapter for this model.
SG250X-24P-K9-EU supports PoE+ on 24 access ports, whereas discontinued SG250X-24-K9-EU does not provide endpoint power. Both models have the same 24-port Gigabit access density and four fixed 10G uplinks. The powered model serves endpoints needing Ethernet power; the non-PoE model suits separately powered devices in existing installations.
Discontinued SG250X-48P-K9-EU provides 48 Gigabit PoE+ access ports, compared with 24 on SG250X-24P-K9-EU. The density difference changes how many endpoint connections fit on one chassis. The 24-port model addresses a smaller existing installation; the 48-port variant addresses a higher connection count without changing the access-speed class.
C1200-24P-4X is the current migration endpoint for discontinued SG250X-24P-K9-EU, through the also-discontinued CBS250-24P-4X-EU. The older model suits exact-match maintenance of installed hardware where its remaining support limits are acceptable; C1200-24P-4X suits purchases requiring the current replacement rather than either retired generation.
Cisco 250 Series switches provide STP/RSTP/MSTP, LACP, port security, RADIUS, and ingress/egress ACLs. SG250X-24P-K9-EU supports 512 ACL rules, eight hardware queues, and 255 active VLANs. These controls support access policies, traffic prioritization, and segmentation; specify the required rule set and VLAN plan during configuration staging.
SG250X-24P-K9-EU contains 512 MB of DRAM, 256 MB of flash, and a 12 Mb packet buffer shared across ports. Its MAC table holds 8000 addresses. These resources perform different roles; compare working memory, firmware storage, packet buffering, and learned-address capacity separately when evaluating the hardware.
