SG250X-48 combines 48 Gigabit RJ-45 access ports with four fixed 10G uplinks, split between two 10GBASE-T connections and two SFP+ cages. This non-PoE, Layer 2+ rack-mount switch belongs to the Cisco 250 Series Smart Switches and serves small-business networks with separately powered endpoints. The discontinued SG250X-48P adds PoE+ for installations requiring endpoint power. The mixed uplink architecture accommodates copper and fiber connections without a removable network card. Port-based and tagged VLANs separate workgroups, while voice VLAN handling assigns phone traffic to its own segment. Smartports and Auto Smartports apply port roles according to connected devices, providing a configuration approach for networks carrying computers, phones, and wireless equipment.

176 Gbps switching capacity provides nonblocking switching across the fixed interfaces, while 130.94 Mpps forwarding describes throughput for 64-byte packets. 32 static IPv4 routes support local subnet routing; the platform uses a dynamically shared 24 Mb packet buffer across its ports. SG250X-48 has 512 MB of DRAM and 256 MB of flash for control functions and software storage. The Cisco 250 Series supports STP/RSTP/MSTP for spanning-tree operation and LACP for link aggregation. Eight hardware queues apply traffic priorities, and IGMP snooping restricts multicast forwarding to requesting receivers. Administrators can use HTTPS browser management or the CLI over SSH/Telnet, with SNMP available for monitoring. 46W worst-case power consumption belongs in the rack power plan; the internal supply takes AC power rather than power from an upstream Ethernet connection. Routing is static rather than dynamic.
SG250X-48 is offered new sealed or certified refurbished, with up to a 3-year extended warranty on new units and up to 1 year on certified refurbished units; every condition has 30-day returns, terms apply. Refurbished units are inspected and bench-tested for power-on and POST, rated-speed links on every port, clean boot, optics bay recognition, PSU status, and fan status; firmware is verified and configuration wiped to factory default. Specify this switch's condition, regional part number, and required accessories on the PO; Cisco's separate limited lifetime hardware warranty and service end October 31, 2026. POs are accepted, government orders have Net-30 terms, and enterprise or volume orders can use UK, EU, US, and MEA regional stock and RMA with advance replacement.

In a mid-sized corporate campus environment, IT deploys the Cisco SG250X-48 as a core distribution switch to connect 48 edge switches via gigabit ports and aggregate traffic over four 10-Gbps SFP+ uplinks to the data center. Benefit: delivers non-blocking throughput, simplifies network segmentation with VLANs, and scales seamlessly as user and IoT device counts grow, ensuring low latency and business-critical application performance.
In a branch office mini-data center running VMware and Hyper-V clusters, the SG250X-48 is installed as a top-of-rack switch to interconnect servers, NAS storage, and backup appliances. Benefit: provides link aggregation (LACP) for 10-Gbps resiliency, advanced QoS for prioritizing VM traffic, and static Layer-3 routing to segment development, test and production networks—optimizing throughput and reducing east-west latency.
A multi-site retail chain uses the Cisco SG250X-48 in each store to consolidate POS terminals, digital signage, customer Wi-Fi access points and VoIP phones across four industry-grade VLANs. Benefit: leverages built-in Layer-3 routing to securely segment guest, management and payment networks, maximizes bandwidth with 48 Gigabit ports, and uses 10-Gbps uplinks for rapid store-to-headquarters data synchronization—enhancing security compliance and customer experience.
When a branch separates departments into different IP subnets, the 16 IP interface ceiling becomes a purchase requirement rather than a port-count question. Map the planned interfaces and external gateway responsibilities first, then attach the addressing and interface plan to the PO.
When several sites will share a configuration baseline, text-editable configuration files allow that baseline to be prepared and downloaded to another switch. CLI privilege levels 1 / 7 / 15 provide distinct administrative access levels. Specify the approved configuration and credential-handling process before placing the PO.
When a replacement unit must be evaluated before production cutover, port mirroring can send traffic from four source ports to one destination port. That limit determines the capture plan rather than the endpoint count. Define the monitored links and analyzer connection before ordering staging hardware.
Switch-supplied power for phones or access points
SG250X-48 provides no PoE output. C1200-48P-4X is a current replacement-line option with 48 Gigabit PoE ports and four 10G SFP+ uplinks; size endpoint power separately.
Four fiber-based 10G uplink connections
SG250X-48 supplies two SFP+ uplinks, with the other two using copper. C1200-48T-4X provides four 10G SFP+ uplinks while retaining 48 Gigabit access ports.

SG250X-48 identifies a 250 Series Gigabit Smart Switch with 10G uplinks; the 48 segment identifies 48 Gigabit access ports. The supplied model name has no regional suffix. SG250X-48-K9-NA is the North American orderable part number, so include the complete regional identity when preparing the PO.
SG250X-48 management options include HTTP/HTTPS web UI, SSH/Telnet CLI, SNMP, Smart Network Application, FindIT Network Manager, the embedded FindIT Network Probe, FindIT Network Discovery Utility, and Cisco Active Advisor. The CLI supports full and menu-based operation. Select the administration and monitoring paths before setting credentials and access policies.
SG250X-48 ended sale on October 30, 2021, and Cisco service ends October 31, 2026. Software maintenance ended October 30, 2022. Its North American replacement, CBS250-48T-4X-NA, is also discontinued; the forward replacement is C1200-48T-4X. Separate continued hardware use from remaining manufacturer support when planning procurement.
ORM offers SG250X-48 new sealed or certified refurbished: new units have up to a 3-year extended warranty; refurbished units have up to 1 year. Both conditions have 30-day returns, terms apply. Cisco's separate limited lifetime hardware warranty is bounded by October 31, 2026; fans and power supplies originally carry 1-year coverage.
SG250X-48 has two 10GBASE-T uplinks and two SFP+ uplinks, rather than four fiber uplinks. For fiber, SFP-10G-SR uses multimode media and SFP-10G-LR uses single-mode media. Match both ends of each link, and specify the required transceivers separately from the chassis when preparing the order.
SG250X-48 supports static IPv4 routing with 32 routes and 16 IP interfaces, placing this configuration in Layer 2+. Routed interfaces can use physical ports, link aggregation groups, VLAN interfaces, or loopback interfaces. Size the route and interface plan before purchase rather than treating the switch as a dynamic-routing replacement.
SG250X-48 uses an internal AC power supply accepting 100-240V AC, with maximum system consumption of 46W. Ethernet uplinks do not power this model. Specify the appropriate regional unit and power cord, and include the switch's consumption in the enclosure or UPS power plan before purchase.
SG250X-48P is the discontinued PoE+ sibling with a shared 382W budget, whereas SG250X-48 does not supply endpoint power. Existing powered deployments may require the former for like-for-like sparing; installations with separately powered equipment use the latter. Treat both models as discontinued hardware rather than current-generation purchase alternatives.
SG250X-48 has 48 Gigabit access ports; SG250X-24 has 24, while each provides four fixed 10G uplinks. Both models are discontinued. SG250X-48 fits like-for-like maintenance of higher-port-count installations; SG250X-24 fits existing lower-port-count deployments. Confirm the required endpoint count before reserving legacy replacement inventory.
C1200-48T-4X has four 10G SFP+ uplinks; SG250X-48 divides its four 10G uplinks between two 10GBASE-T connections and two SFP+ cages. C1200-48T-4X is the current replacement-line choice for all-fiber uplink layouts. The discontinued SG250X-48 serves existing installations requiring its mixed copper and fiber uplink arrangement.
