SG250X-48-K9-UK combines 48 Gigabit access ports with four fixed 10G uplinks split between two 10GBASE-T connections and two SFP+ slots. The SG250X-48 is a non-PoE, Layer 2+ smart-managed switch occupying one rack unit for small-business access networks connecting computers, printers, servers, and separately powered network devices. Its mixed uplink media accommodates copper and fiber connections without an uplink expansion card. Cisco 250 Series traffic prioritization handles delay-sensitive voice and video alongside ordinary data traffic, while browser-based configuration provides local administration. The discontinued SG250X-48P-K9-UK differs by adding PoE+ for powered endpoints. For an existing installation, the choice turns on whether connected equipment needs Ethernet power and whether the upstream connections require copper, fiber, or both, rather than simply matching the access-port count.

176 Gbps switching capacity carries simultaneous access and uplink traffic through a nonblocking switching fabric. 130.94 Mpps forwarding applies to 64-byte packets, distinguishing packet-processing performance from aggregate bandwidth. Static IPv4 routing supports 32 routes for local subnet forwarding rather than dynamic route exchange. SG250X-48-K9-UK combines 512 MB of DRAM for runtime operations with 256 MB of flash for image and configuration storage. A dynamically shared 24 Mb packet buffer serves all ports, while the MAC table accommodates 8000 addresses. STP, RSTP, and MSTP control Layer 2 loops; LACP supports aggregated links. Eight hardware queues provide strict-priority or Weighted Round-Robin scheduling, and ingress policing and egress shaping control traffic rates. Textview CLI supports scripted administration, while SNMP provides monitoring access. Dual firmware images support recovery during image changes, and the front-panel USB Type-A slot handles configuration and image transfers. Two fans cool the chassis across its 0°C to 50°C operating range.
ORM Systems offers SG250X-48-K9-UK new sealed with up to a 3-year extended warranty or certified refurbished with up to 1 year; every condition includes 30-day returns, terms apply. Cisco's separate limited lifetime hardware warranty includes a 1-year limit for fans and power supplies, with Cisco service ending October 31, 2026. Certified refurbished units are inspected and bench-tested, with every port linking at rated speed, optics bay recognition, firmware verified, and configurations wiped to factory default. Specify condition and quantity on the purchase order; enterprise and volume orders have PO acceptance, Net-30 for government, RMA with advance replacement, and regional stock/RMA in the UK, EU, US, and MEA.

When a small office needs separate departmental subnets, the Cisco 250 Series supports 16 IP interfaces for local routing. Interfaces can be assigned to physical ports, VLANs, link aggregation groups, or loopbacks. Check the interface assignments and the external router's responsibilities before specifying the switch on the purchase order.
When several offices need the same initial configuration, the Cisco 250 Series accepts text-editable configuration files and supports autoconfiguration through SCP. A shared configuration can establish common settings while site-specific addressing remains separate. Specify the approved configuration file, management addressing, and secure transfer method before placing the purchase order.
When a replacement switch must reproduce an existing troubleshooting arrangement, port mirroring can copy traffic from four source ports to one destination port. VLAN mirroring supports four source VLANs to one destination. Reserve the analyzer connection and record which traffic sources must be visible before the purchase order is finalized.
Power delivery to phones or access points
SG250X-48-K9-UK supplies data without endpoint power. C1200-48P-4X is the current alternative for 48 powered Gigabit connections, with four 10G SFP+ uplinks instead of mixed copper and SFP+ uplinks.
Four fiber-based 10G uplinks
SG250X-48-K9-UK has two SFP+ uplinks; its other two 10G uplinks are copper. C1200-48T-4X provides four 10G SFP+ uplinks while retaining 48 Gigabit access ports.
More than 32 static routes
SG250X-48-K9-UK supports a maximum of 32 IPv4 static routes. A requirement above that limit needs a routing device with greater route capacity.

SG250X-48-K9-UK identifies a Cisco 250 Series smart switch with 48 Gigabit access ports and 10G uplinks. SG250X identifies the Gigabit model with 10G uplinks, 48 states the access-port count, and UK selects the regional ordering form used for the United Kingdom and other designated markets.
SG250X-48-K9-UK supports browser management through HTTP/HTTPS, Textview CLI over SSH or Telnet, and SNMP versions 1, 2c, and 3. Network-level options include Smart Network Application, FindIT Network Manager with embedded FindIT Network Probe, FindIT Network Discovery Utility, and Cisco Active Advisor. Cisco Network Plug and Play handles automated provisioning.
SG250X-48-K9-UK is discontinued, with end of sale on October 30, 2021 and last support on October 31, 2026. Software maintenance ended October 30, 2022. Cisco's original replacement, CBS250-48T-4X-UK, is also discontinued; the replacement chain now ends at C1200-48T-4X, which retains 48 Gigabit access ports.
ORM Systems offers SG250X-48-K9-UK new sealed with up to a 3-year extended warranty, or certified refurbished with up to 1 year. Both conditions include 30-day returns; terms apply. Cisco's separate limited lifetime hardware warranty has a 1-year fan and power-supply limit, and Cisco service ends October 31, 2026.
The Cisco 250 Series supports static IPv4 routing between VLANs, with 32 routes and 16 IP interfaces, corresponding to Layer 2+ capability. Physical ports, VLAN interfaces, link aggregation groups, and loopbacks can carry Layer 3 interfaces. Match the subnet plan to those limits rather than treating static routing as dynamic route exchange.
SG250X-48-K9-UK has four fixed 10G uplinks: two 10GBASE-T copper ports and two SFP+ slots. These are additional to the 48 Gigabit access ports. The copper and SFP+ connections are separate interfaces, so the uplink layout is not a pair of shared copper/fiber combo ports.
SG250X-48 accepts SFP-10G-SR for 10G multimode fiber and SFP-10G-LR for 10G single-mode fiber. SFP-10G-LR supports links to 10 km, while SFP-H10GB-CU1M provides a 1 m direct-attach copper connection. Specify the actual transceiver or cable PID and match the remote interface and installed media.
SG250X-48P-K9-UK adds PoE+ on 48 access ports with a shared 382W budget, while SG250X-48-K9-UK provides no endpoint power. Both models are discontinued. The non-PoE model serves separately powered equipment; the PoE+ model serves endpoints requiring Ethernet power, with allocation constrained by its total power budget.
SG250X-48-K9-UK offers 48 Gigabit access ports, while SG250X-24-K9-UK offers 24. Both are discontinued; the comparison is relevant to matching existing installations rather than selecting a current replacement. The larger model suits denser connection requirements, while the smaller model suits installations needing fewer access connections.
C1200-48T-4X provides four 10G SFP+ uplinks, while SG250X-48-K9-UK splits its four 10G uplinks between two copper connections and two SFP+ connections. C1200-48T-4X is the current successor after the discontinued CBS250-48T-4X-UK. The older switch matches mixed-media installations; the successor serves buyers specifying four fiber-capable uplinks.
Yes, SG250X-48 occupies one rack unit and measures 440 mm wide, 44 mm high, and 257 mm deep. The unit weighs 3 kg, and the standard package includes a mounting kit. Allow installation space around the chassis and confirm the rack mounting arrangement before placing the order.
SG250X-48 accepts 100-240V AC through an internal universal power supply at 50-60 Hz. Maximum system consumption is 46W at 110V or 45.6W at 220V. A power cord is included, and an external power adapter is unnecessary. Confirm the regional mains connection when specifying the order.
