SG250X-24P-K9 is a Layer 2+ smart-managed access switch with 24 Gigabit PoE+ ports and fixed copper and fiber uplinks. Two 10GBASE-T ports and two 10G SFP+ cages connect upstream equipment without an additional uplink card. The rack-mount 1U chassis belongs to the Cisco 250 Series Smart Switches, serving small-business networks with wired computers, servers, IP phones, wireless access points, and cameras. Ethernet-powered endpoints receive data and power through their network connection, while the switch itself requires an AC supply. The discontinued SG250X-24-K9-NA provides the corresponding non-PoE configuration for endpoints with separate power.
SG250X-24P-K9 price for new stock is $792.75, a 30.9% saving from the Cisco list price of $1,147.00. SG250X-24P-K9 refurb price is $984.38. SG250X-24P-K9 is in stock and available for next-day dispatch. (terms applied)

128 Gbps switching capacity supports nonblocking forwarding, while 95.23 Mpps describes performance with 64-byte packets. 195W of shared PoE output requires endpoint allocation rather than assuming maximum delivery across every powered port. Static routing supports inter-VLAN forwarding within 32 routes and 16 IP interfaces; dynamic route learning is not available. SG250X-24P-K9 carries 512 MB of memory and 256 MB of flash for management software and configuration storage. An 8000-entry MAC table and 255 active VLANs bound address learning and segmentation. STP, RSTP, and MSTP provide spanning-tree operation, while LACP aggregates compatible connections. Dual software images retain an alternate image for firmware maintenance. Two fans support operation from 0°C to 50°C, making cabinet ventilation part of installation planning. 260.1W maximum consumption including PoE provides the electrical-load reference rather than the endpoint budget alone.
ORM Systems offers SG250X-24P-K9 new sealed and certified refurbished, with up to a 3-year extended ORM warranty for new units and up to 1 year for certified refurbished units; Cisco's separate limited lifetime hardware warranty and support end October 31, 2026. Certified refurbished units are inspected and bench-tested for power-on and POST, every port linking at rated speed, clean boot, and PoE output under load on every powered port, with firmware verified and configuration wiped to factory default. Specify condition, quantity, regional requirements, and required connection parts on the PO; returns are 30 days on every condition, terms apply. Enterprise and volume POs are accepted, with Net-30 for government, RMA with advance replacement, and regional stock/RMA across the UK, EU, US, and MEA.

When replacing locally powered phones, cameras, or access points with Ethernet-powered endpoints, the per-port ceiling is 30W. Device count alone does not establish the power requirement; record each endpoint's requested allocation, account for simultaneous operation, and approve the endpoint power schedule before issuing the PO.
When preparing a spare before a maintenance window, port mirroring can send traffic from four source ports to one destination for analysis. Include the monitoring connection in the staging plan, identify the traffic to inspect, and specify the required test connections before approving the purchase.
When standardizing equipment across regional offices, SG250X-24P-K9-NA is the United States ordering form rather than a different software tier. Keep the complete regional identifier on each order line so receiving staff can match equipment to its destination; confirm regional requirements before releasing the PO.
Endpoint power above 30W
An individual powered port cannot deliver more than 30W. Endpoints requiring higher delivery need a different power source; do not size the purchase from aggregate output alone.
Cisco support beyond October 2026
Cisco support for this model ends October 31, 2026. Purchases requiring a current replacement should specify C1200-24P-4X rather than the discontinued intermediate CBS250-24P-4X-NA.
Dynamic route learning
Routing uses static configuration rather than dynamic route learning. Networks requiring automatic route exchange need a separate routing device instead of assigning that function to this switch.

SG250X-24P-K9 identifies the 250 Series Gigabit smart configuration with 10G uplinks: 24 denotes the access-port count and P the PoE+ model. SG250X-24P-K9-NA is the United States regional ordering form. The regional suffix completes the hardware identifier rather than selecting a software license tier.
SG250X-24P-K9 supports an HTTP/HTTPS web UI, full or menu-based CLI over SSH or Telnet, SNMP, Smart Network Application, FindIT Network Manager with an embedded FindIT Network Probe, and Cisco Active Advisor. SNMP versions 1, 2c, and 3 provide additional monitoring and administration choices.
SG250X-24P-K9 ended Cisco sales on October 30, 2021, and reaches its last date of support on October 31, 2026. C1200-24P-4X is the current migration endpoint after the also-discontinued CBS250-24P-4X-NA. Remaining service entitlement does not extend the original switch beyond its support deadline.
ORM Systems supplies SG250X-24P-K9 new sealed or certified refurbished, with up to a 3-year extended ORM warranty for new units and up to 1 year for refurbished units. Returns are 30 days on every condition; terms apply. Cisco's limited lifetime hardware warranty and support end October 31, 2026.
195W is the shared PoE budget for SG250X-24P-K9, and an individual powered port can supply 30W. Twenty-four ports at 30W would require 720W, so maximum per-port delivery cannot operate simultaneously across every endpoint. Establish individual endpoint allocations before approving the equipment order.
The SG250X-24P configuration supports SFP-10G-SR for multimode fiber and SFP-10G-LR for single-mode fiber in its SFP+ uplink cages. Match each connection to the peer transceiver and installed fiber. Specify the selected transceiver PID separately on the PO rather than treating every fiber connection as interchangeable.
Yes, the 250 Series supports inter-VLAN forwarding through static routing, with 32 static routes and 16 IP interfaces. This capability handles manually defined paths rather than dynamic route learning. Check the intended subnet and next-hop configuration before assigning routing responsibilities to the switch.
SG250X-24P-K9 supplies PoE+ endpoint power where the discontinued SG250X-24-K9-NA does not; both provide 24 Gigabit access ports and fixed 10G uplinks. The powered model serves Ethernet-powered phones, cameras, and access points; the nonpowered model serves endpoints that receive their power from a separate source.
SG250X-24P-K9 has four 10G uplinks, whereas the discontinued SG250-26P-K9-NA has two Gigabit copper/SFP combo uplinks. Copper and fiber share each combo interface on the latter model. The 10G configuration serves faster upstream connections; the Gigabit configuration serves existing 1G uplink requirements in legacy installations.
C1200-24P-4X is the current migration endpoint for SG250X-24P-K9 through the discontinued CBS250-24P-4X-NA. The original model reaches its support deadline on October 31, 2026. SG250X-24P-K9 addresses matching legacy equipment, while C1200-24P-4X addresses purchases requiring the current replacement rather than another discontinued step in the migration chain.
