SG250X-24-K9-NA is a Layer 2+ smart managed switch with 24 Gigabit Ethernet access ports and four fixed 10G uplinks, split between two 10GBASE-T connections and two SFP+ cages. The non-PoE design connects independently powered computers, printers, servers, and other office equipment rather than delivering endpoint power. A full-width 1U rack chassis places the Cisco 250 Series in small-business equipment racks without an uplink expansion card. Copper and fiber-facing uplink connections accommodate different neighboring interfaces and installed media. The discontinued SG250X-24P-K9-NA adds PoE+ with a shared 195W budget, whereas this model leaves endpoint power outside the switch purchase. The Gigabit smart switch provides configurable segmentation and traffic controls rather than operating solely as an unmanaged connection point.

128 Gbps switching capacity provides a nonblocking fabric for the access and uplink interfaces. 95.23 Mpps forwarding capacity specifies packet processing with 64-byte packets. Static IPv4 routing supports 32 routes; dynamic route exchange is outside this model's feature set. STP/RSTP/MSTP supplies spanning-tree options for loop control, while LACP combines physical connections into logical links. SG250X-24-K9-NA carries 512 MB of memory and 256 MB of flash for its embedded software and configuration storage. The 8000-entry MAC address table establishes the learned-address limit, and a shared 12 Mb packet buffer holds queued traffic across ports. Management includes an HTTP/HTTPS browser interface, a scriptable Textview CLI, and SNMP monitoring. Eight hardware queues separate traffic classes, with strict-priority and Weighted Round-Robin scheduling available. A maximum draw of 29.1W provides the device's electrical allowance for power planning. One cooling fan makes the chassis an actively cooled unit rather than a fanless switch.
Specify SG250X-24-K9-NA as new sealed or certified refurbished, and list the required power cord, mounting hardware, and accessories on the PO. Refurbished units are inspected and bench-tested, including every port linking at rated speed and optics bay recognition; firmware is verified and configurations are wiped to factory default. ORM warranty provides up to 3-year extended coverage for new units or up to 1 year for certified refurbished units, with 30-day returns on every condition, terms apply; Cisco's limited lifetime warranty ends October 31, 2026. Enterprise and volume orders accept POs, government Net-30, and RMA with advance replacement.

Where multiple small offices need the same segmentation plan, the Cisco 250 Series supports 255 active VLANs and automatic voice VLAN assignment. A common configuration can separate office data and voice traffic without changing the switch hardware. Count the required VLANs and define the voice policy before issuing the PO.
Where replacement units must be staged before a maintenance window, dual firmware images allow the Cisco 250 Series to retain an alternate image during software preparation. Upgrades can use a browser, TFTP, or SCP over SSH. Specify the intended firmware image and verify the management connection before adding a spare to the PO.
PoE-powered phones or access points
SG250X-24-K9-NA does not deliver endpoint power. C1200-24P-4X is a current PoE alternative in the replacement family and uses four 10G SFP+ uplinks.
Dynamic routing between local subnets
SG250X-24-K9-NA supports static IPv4 routing with a 32-route ceiling, not dynamic route exchange. Networks requiring dynamic routing need a different routing-capable switch or a separate router.

SG250X-24-K9-NA identifies an Americas-region Gigabit smart switch with 24 access ports and 10G uplinks. SG250X identifies the Gigabit model group with 10G uplinks, 24 specifies the access-port count, and NA selects the regional ordering version. The configuration has no PoE output and uses fixed uplinks.
SG250X-24-K9-NA supports an HTTP/HTTPS web interface, Textview CLI with SSH or Telnet access, SNMP, Smart Network Application, FindIT Network Manager with an embedded probe, and Cisco Active Advisor. FindIT Network Discovery Utility also locates devices and launches configuration. The CLI supports both scriptable and menu-based operation.
SG250X-24-K9-NA reached end of sale on October 30, 2021, and Cisco support ends October 31, 2026. Software maintenance ended October 30, 2022. Its direct replacement, CBS250-24T-4X-NA, is also discontinued; C1200-24T-4X is the current endpoint of that replacement chain. Plan purchases around the original model's support deadline.
ORM Systems offers SG250X-24-K9-NA new sealed or certified refurbished, with up to 3-year extended warranty for new units and up to 1 year for refurbished units. Cisco's limited lifetime warranty is bounded by its October 31, 2026 support deadline. Both conditions have 30-day returns; terms apply. Refurbished units are inspected and bench-tested.
No, SG250X-24-K9-NA does not supply Power over Ethernet on its access ports. Connected phones, access points, cameras, or other powered devices need an independent power source or separate power-injection equipment. The internal AC supply powers the switch itself and does not create an endpoint PoE budget.
SG250X-24-K9-NA has four fixed 10G uplinks: two 10GBASE-T ports and two SFP+ cages. SFP-10G-SR supports multimode fiber, SFP-10G-LR supports single-mode fiber, and SFP-H10GB-CU1M provides a direct-attach copper connection. Match the selected media to the neighboring interface and include the required accessory PID on the order.
Yes, SG250X-24-K9-NA supports static IPv4 routing between configured interfaces, with a maximum of 32 static routes and 16 IP interfaces. Interfaces can be associated with physical ports, link aggregation groups, VLANs, or loopbacks. The routing capability fits fixed route plans rather than deployments that require dynamic route exchange.
The Cisco 250 Series SG250X-24 requires one rack unit in a standard equipment rack. Its chassis measures 440 mm wide, 44 mm high, and 257 mm deep, with a weight of 2.66 kg. Mounting brackets secure the chassis to the rack; verify bracket and power-cord inclusion when specifying the order.
No, SG250X-24-K9-NA does not form a hardware stack. The Cisco 250 Series supports Smart Network Application and single-IP management for network-level administration, but those functions do not combine switches into a shared forwarding chassis. Treat additional units as separately connected switches rather than ordering dedicated stacking cables or adapters.
SG250X-24P-K9-NA supplies PoE+ across 24 access ports with a shared 195W budget, while SG250X-24-K9-NA supplies no endpoint power. Both models are discontinued. The non-PoE version suits independently powered equipment; the PoE+ version suits existing installations needing switch-delivered endpoint power within that shared budget.
SG250X-48-K9-NA provides 48 Gigabit access ports, compared with 24 on SG250X-24-K9-NA. Both are discontinued non-PoE models. The smaller version suits an existing installation with fewer endpoint connections, while the larger version suits buyers maintaining an installation that requires the higher access-port count in one chassis.
C1200-24T-4X provides four 10G SFP+ uplinks, whereas SG250X-24-K9-NA provides two 10GBASE-T uplinks and two 10G SFP+ cages. SG250X-24-K9-NA is discontinued; C1200-24T-4X is its current successor through the discontinued CBS250-24T-4X-NA. The older configuration suits existing copper uplink requirements, while the current model suits an all-SFP+ uplink plan.
