SG250-26-K9-EU is a fanless Layer 2+ smart-managed switch with 24 Gigabit copper access ports and two fixed 1G copper/SFP combo uplinks in a full-width 1U rack chassis. The Cisco 250 Series Smart Switches serve small-business networks connecting computers, printers, servers, and independently powered communications devices. Copper and fiber can be mixed across the uplinks, but each combo connection activates only one medium at a time. The discontinued SG250-26HP-K9-EU adds PoE+ with a shared 100W budget, whereas this model requires separate endpoint power. Voice VLAN handling separates phone traffic, while QoS prioritizes delay-sensitive applications. Auto Smartports applies port settings using device discovery, and port security can restrict learned source addresses. The SG250-26 also includes a front-panel USB connection for image and configuration transfers.

52 Gbps switching capacity provides nonblocking forwarding across the available interfaces. 38.69 Mpps forwarding at 64-byte packets defines the packet-processing rate for small-frame traffic. Static IPv4 routing supports 32 routes and 16 IP interfaces for communication between local subnets; dynamic routing is not included. SG250-26-K9-EU carries 512 MB of DRAM and 256 MB of flash for its embedded software and saved configuration. A dynamically shared 12 Mb packet buffer accommodates traffic bursts across the ports. STP/RSTP/MSTP protect against Layer 2 loops, and LACP supports four aggregation groups with eight active ports per group. The browser interface offers basic and advanced modes, while the scriptable CLI accepts remote administration over SSH or Telnet. SNMP versions 1, 2c, and 3 integrate device monitoring. Dual software images support firmware upgrades, and an 8000-entry MAC table accommodates learned Ethernet addresses. 18.9W worst-case consumption supplies a load figure for circuit and backup-power sizing.
Specify SG250-26-K9-EU, quantity, regional version, and new sealed or certified refurbished condition on the purchase order. Refurbished units are inspected and bench-tested for power-on and POST, rated-speed links on every port, optics bay recognition, PSU status, and clean boot, with firmware verified and configurations wiped to factory default. ORM Systems covers new units with up to a 3-year extended warranty and certified refurbished units for up to 1 year; 30-day returns apply to every condition, terms apply, while Cisco's separate limited lifetime hardware warranty is bounded by October 31, 2026. Enterprise and volume purchasing supports POs, Net-30 for government, and RMA with advance replacement, with UK, EU, US, and MEA stock/RMA regions.

Replacement PID | C1200-24T-4G |
Replacing discontinued SLM2024T-EU hardware starts with an inventory of the existing installation. That older model ended sale May 10, 2018, and this switch is its designated replacement. Capture interface assignments, management settings, and accessory requirements before specifying the replacement quantity and condition on the purchase order.
Standardizing several small-business sites requires repeatable provisioning alongside the hardware order. Network Plug and Play supports PnP Connect, while DHCP autoconfiguration supports options 12, 66, 67, 129, and 150. Define the configuration-file workflow and provisioning dependencies before assigning hardware quantities to each site on the purchase order.
Adding a switch to a troubleshooting bench requires a connection plan for the analyzer as well as the devices under test. Four source ports can be mirrored to one destination port for traffic analysis. Reserve that analyzer connection, select the source interfaces, and confirm cabling quantities before issuing the purchase order.
10G uplinks to distribution
SG250-26-K9-EU limits its fixed combo uplinks to 1G. C1200-24T-4X provides 24 Gigabit access ports and four 10G SFP+ uplinks as a current alternative.
Switch-powered phones or access points
SG250-26-K9-EU provides data connections without PoE output. C1200-24P-4G is a current 24-port Gigabit PoE alternative with four dedicated 1G SFP uplinks.

SG250 names the Gigabit 250 Series family, 26 describes 24 copper access ports plus two copper/SFP combo ports, and EU is the regional ordering suffix in SG250-26-K9-EU. The complete identifier retains K9. This version serves the European Union and other designated markets, not just one country.
SG250-26-K9-EU supports an HTTP/HTTPS web interface, CLI over SSH or Telnet, SNMP, Smart Network Application, FindIT Network Manager with an embedded Probe, and Cisco Active Advisor. FindIT Network Discovery assists device discovery; Network Plug and Play supports provisioning through PnP Connect. The browser interface includes basic and advanced modes.
SG250-26-K9-EU is discontinued, with end of sale on October 30, 2021, and last support on October 31, 2026. Software maintenance ended October 30, 2022. The current migration endpoint is C1200-24T-4G; the intermediate CBS250-24T-4G-EU replacement is also discontinued and should not be treated as the current generation.
ORM Systems offers SG250-26-K9-EU new sealed or certified refurbished, with up to a 3-year extended warranty for new units and up to 1 year for refurbished units. Returns are 30 days on either condition; terms apply. Cisco's limited lifetime hardware warranty is separately bounded by the last support date, October 31, 2026.
SG250-26-K9-EU replaces the discontinued SLM2024T-EU, also known as the SG200-26 Gigabit Smart Switch. SLM2024T-EU ended sale May 10, 2018. Plan the change around the existing installation: review interface assignments, management settings, endpoint power arrangements, and accessory requirements before preparing the replacement purchase order.
The Cisco SG250-26 supports MGBSX1 multimode and MGBLX1 single-mode 1G SFP transceivers in its combo uplinks. MGBSX1 supports 500 m, while MGBLX1 supports 10 km. Each combo connection uses either its copper socket or its SFP cage at a time, so an installed optic does not add an independent port.
SG250-26-K9-EU supports IPv4 static routing with up to 32 static routes and 16 IP interfaces. Routing interfaces can use physical ports, link aggregation groups, VLAN interfaces, or loopback interfaces. This Layer 2+ capability supports local subnet communication, but route planning must remain within those limits.
No, the Cisco SG250-26 uses an internal universal AC supply accepting 100-240V at 50-60 Hz. A power cord supplies the switch directly, and the package includes a mounting kit. The 18.9W worst-case draw is switch operating consumption, not a budget for powering connected devices.
Yes, SG250-26-K9-EU is a 1U rack-mount switch measuring 440 mm wide, 44 mm high, and 202 mm deep. Its weight is 2.72 kg, and cooling is fanless. Check enclosure depth, cable clearance, and mounting-kit inclusion when specifying the physical installation and the condition required on the order.
SG250-26HP-K9-EU supplies PoE+ from a shared 100W budget, while SG250-26-K9-EU provides no endpoint power. The HP model is also discontinued. The non-PoE model serves independently powered devices; the HP model addresses legacy installations that already depend on switch-supplied power and fit within its shared budget.
SG250-50-K9-EU provides 48 copper access ports compared with 24 on SG250-26-K9-EU, and both products are discontinued. The smaller model matches an existing installation needing fewer connections; the larger model addresses higher connection density in a legacy estate. Neither comparison changes the lifecycle limits attached to these older switches.
C1200-24T-4G has four dedicated 1G SFP uplinks, while SG250-26-K9-EU has two 1G copper/SFP combo uplinks. C1200-24T-4G is the current migration endpoint. Existing equipment matching may call for the older design; a new purchase requiring separate fiber uplink ports points to the current successor.
