SG250X-24-K9 combines 24 Gigabit Ethernet access ports with four fixed 10G uplinks in a non-PoE, Layer 2+ smart-managed switch. Two 10GBASE-T connections accommodate copper uplinks, while two SFP+ cages provide interfaces for optical connections without a removable uplink card. The full-width 1U chassis belongs to the Cisco 250 Series Smart Switches family for small-business networks connecting independently powered Ethernet equipment. This 24-port Gigabit Smart Switch with 10G Uplinks separates endpoint connections from upstream connections, so uplinks do not consume access ports. Discontinued SG250X-24P-K9-NA is the PoE+ counterpart, adding a shared 195W endpoint-power budget for installations that need power delivered through access connections.

128 Gbps switching capacity accommodates traffic across the fixed interfaces. 95.23 Mpps forwarding performance defines the packet-processing limit when sizing traffic loads. 32 static IPv4 routes support local inter-VLAN communication, keeping the routing design within a fixed route inventory rather than a dynamic-routing deployment. SG250X-24-K9 carries 512 MB of DRAM and 256 MB of flash for control software and saved configuration. A dynamically shared 12 Mb packet buffer serves traffic across all ports rather than reserving that capacity for each connection. The SG250X-24 supports STP/RSTP/MSTP for loop control and LACP for link aggregation, while eight hardware queues provide traffic-prioritization resources. An 8000-entry MAC table bounds the learned-address inventory. Browser access offers basic and advanced configuration modes, and a full or menu-based CLI supports scripted administration over SSH or Telnet. These management options allow configuration through either graphical workflows or command-based procedures without changing the hardware configuration.
Order SG250X-24-K9 in new sealed or certified refurbished condition, specifying quantity, regional version, and required accessories on the purchase order. Certified refurbished units are inspected and bench-tested, including rated-speed links on every port and optics bay recognition, with firmware verified and configuration wiped to factory default. ORM Systems provides up to a 3-year extended warranty on new units and up to 1 year on certified refurbished units, plus 30-day returns on every condition; terms apply, while Cisco's separate Limited Lifetime warranty and applicable service end October 31, 2026, subject to eligibility. For enterprise and volume orders, ORM Systems accepts POs and offers Net-30 for government plus RMA with advance replacement.

When a small office separates workgroups but needs local communication between them, the switch supports 16 IP interfaces. Physical ports, link aggregation groups, VLAN interfaces, and loopback interfaces can carry those assignments. Before issuing the purchase order, specify the interface layout and which device retains the external gateway role.
When a spare must be prepared before replacing an installed unit, dual firmware images allow an approved image to coexist with an alternate image. The front-panel USB Type-A connection supports image and configuration transfer. Specify the required firmware build and staging configuration before the purchase order.
When several offices need a common administration workflow, Smart Network Application can discover topology, show link status, apply configurations, and upgrade images across multiple switches. An embedded FindIT Network Probe removes the need for a separate probe host at each site. Specify the management workflow and account permissions before ordering.
PoE power for connected endpoints
SG250X-24-K9 supplies data but no endpoint power. C1200-24P-4X provides 24 PoE+ access ports and four 10G SFP+ uplinks for installations requiring powered Ethernet connections.
Four optical 10G uplink connections
SG250X-24-K9 has two SFP+ uplink cages; the other two uplinks are copper. C1200-24T-4X supplies four 10G SFP+ uplinks for an all-optical uplink requirement.
Fanless operation in occupied rooms
SG250X-24-K9 uses one fan rather than passive cooling. C1200-24T-4X is fanless and retains 24 Gigabit access ports, but changes every 10G uplink to SFP+.
Cisco support beyond October 2026
SG250X-24-K9 reaches its last Cisco support date on October 31, 2026. C1200-24T-4X is the current migration endpoint; intermediate CBS250-24T-4X-NA is already discontinued.

SG250X-24-K9 identifies a Cisco 250 Series Smart Switch with 24 Gigabit access ports and four 10G uplinks. SG250X names the 10G-uplink model group, while 24 is the access-port count. Regional forms include SG250X-24-K9-NA for North America and SG250X-24-K9-UK for the United Kingdom; neither denotes a software tier.
Cisco 250 Series Smart Switches support HTTP/HTTPS web management, a full or menu-based CLI over SSH/Telnet, SNMP versions 1/2c/3, Smart Network Application, and FindIT Network Manager with an embedded FindIT Network Probe. Cisco Active Advisor supplies additional monitoring, while FindIT Network Discovery Utility provides discovery and inventory. Browser access includes basic and advanced modes.
SG250X-24-K9 is discontinued: end of sale was October 30, 2021, and the last Cisco support date is October 31, 2026. Software maintenance ended October 30, 2022. Existing hardware can still be ordered by condition, but a new purchase does not restart Cisco's published lifecycle.
ORM Systems offers SG250X-24-K9 new sealed or certified refurbished, with new-unit extended warranty up to 3 years and refurbished warranty up to 1 year. Returns are 30 days for either condition; terms apply. Cisco's separate Limited Lifetime warranty and applicable service end October 31, 2026, subject to eligibility.
No, SG250X-24-K9 does not supply PoE or PoE+ to connected devices. Access connections carry data without an endpoint power budget. Phones, cameras, and wireless access points therefore need independent power when connected to this model. The non-PoE hardware configuration must be settled before ordering.
Four 10G uplinks are built into SG250X-24-K9: two 10GBASE-T copper ports and two SFP+ cages. The copper ports do not consume the optical connections. Fiber connections use separately ordered transceivers such as SFP-10G-SR or SFP-10G-LR, selected to match the fiber and far-end interface.
Yes, SG250X-24-K9 supports static IPv4 routing between VLANs, with 32 static routes and 16 IP interfaces. Layer 3 interfaces can use physical ports, link aggregation groups, VLAN interfaces, or loopbacks. The switch fits a static routing design rather than a deployment requiring a dynamic routing protocol.
Yes, the Cisco SG250X-24 fits a full-width 1U rack position and includes a mounting kit. The chassis measures 440 mm wide, 44 mm high, and 257 mm deep, with a weight of 2.66 kg. Allow for installed cables and the switch's fan-driven airflow when planning the rack position.
SFP-H10GB-CU1M, SFP-H10GB-CU3M, and SFP-H10GB-CU5M support SG250X-24 10G direct-attach connections at 1 m, 3 m, and 5 m, respectively. These cables use the fixed SFP+ cages rather than the copper uplink ports. Specify the cable PID and length against the actual equipment spacing and far-end interface before ordering.
SG250X-24P-K9-NA adds 24 PoE+ ports and a shared 195W budget, whereas SG250X-24-K9 provides no endpoint power. Both are discontinued models from the same family. The PoE version serves powered-endpoint replacement requirements; the non-PoE version suits equipment that already has its own power.
SG250X-48-K9-NA has 48 Gigabit access ports, compared with 24 on SG250X-24-K9. Both are discontinued non-PoE models. The larger model suits an existing installation needing more copper connections in one switch; the smaller model suits like-for-like replacement where the required access-port count remains 24.
C1200-24T-4X provides four 10G SFP+ uplinks, while SG250X-24-K9 divides its four 10G uplinks between two copper ports and two SFP+ cages. C1200-24T-4X is the current migration endpoint after discontinued CBS250-24T-4X-NA. The older model serves matched copper-uplink replacement requirements; the successor suits installations requiring four optical uplinks.
