SF250-48HP-K9-EU provides Layer 2+ smart-managed switching through 48 Fast Ethernet PoE+ access ports and four fixed Gigabit uplinks. Two uplinks use dedicated SFP cages; the other two offer copper/SFP combo connections, with one medium active per pair. The Rack-Mount 1U chassis belongs to the Cisco 250 Series Smart Switches family and serves small-business networks connecting phones, cameras, computers, and wireless access points. Voice prioritization and port authentication support mixed endpoint deployments without changing the access ports' 100 Mbps ceiling. Compared with SF250-48-K9-EU, the powered model adds PoE+; both models are discontinued. The SF250-48HP configuration combines powered copper access with fiber connectivity where endpoint speed requirements remain within Fast Ethernet limits.

17.6 Gbps switching capacity provides nonblocking traffic handling across the installed interfaces. 13.1 Mpps forwarding performance applies to 64-byte packets, distinguishing packet-processing throughput from aggregate bandwidth. 195W of shared PoE capacity supplies connected endpoints within the available allocation. Static IPv4 routing supports 32 routes for explicitly configured destinations rather than dynamic route learning. SF250-48HP-K9-EU uses 512 MB of memory and 256 MB of flash for switch operation and image storage. A dynamically shared 24 Mb packet buffer serves traffic across all ports instead of reserving a separate fixed allocation for each connection. STP/RSTP/MSTP provide spanning-tree operation, while LACP supports aggregated links between compatible peers. Eight hardware queues support traffic prioritization; 512 access-control rules and 802.1X authentication provide controls for endpoint access and traffic filtering. 265.2W maximum consumption with PoE is the figure to use when sizing the AC power allocation, rather than treating endpoint power as the complete switch load.
SF250-48HP-K9-EU is offered new sealed with up to 3-year extended ORM warranty or certified refurbished with up to 1 year; every condition includes 30-day returns, with terms applying. Refurbished units are inspected and bench-tested for power-on and POST, rated-speed port links, clean boot, PoE output under load, optics bay recognition, PSU status, and fan status; firmware is verified and configurations are wiped to factory default. Specify condition and required accessories on the purchase order; Cisco's separate limited lifetime hardware warranty is bounded by July 31, 2027, with 1-year fan and power-supply coverage subject to eligibility. Enterprise and volume purchasing supports PO acceptance, Net-30 for government, advance-replacement RMA, and regional stock/RMA across UK, EU, US, and MEA.

When switches are being staged for several branches, configuration delivery needs to match the provisioning services already in use. DHCP options 66 and 67 and Cisco Network Plug and Play support automated setup workflows. Specify the intended provisioning method and configuration-delivery requirements before issuing the purchase order.
When a site moves communication between local network segments onto an access switch, interface count becomes part of the purchase decision. The switch supports 16 IP interfaces. Map the required segment interfaces and identify traffic that must remain on an external router before specifying the deployment configuration.
When a spare is purchased for reproducing endpoint or application faults, traffic capture requirements should be established before staging. Port mirroring supports four source ports feeding one destination port. Check the required observation points and include the analyzer connection and associated cabling in the purchase order.
Gigabit speeds on every endpoint
The 48 access ports stop at 100 Mbps. Gigabit capability is confined to the uplinks, so faster uplinks do not increase individual endpoint connection speeds.
Full-power PoE+ across every port
The shared 195W allowance cannot supply 30W simultaneously on all 48 powered ports. A requirement for that load exceeds this switch's available endpoint power.
Dynamic routing between network segments
Routing uses configured static destinations rather than dynamic route exchange. Networks requiring routing neighbors to discover and update paths automatically exceed this switch's routing capabilities.
10G connections to distribution
The fixed uplinks operate at 1 Gbps and cannot accept an uplink expansion card. A distribution connection requiring 10 Gbps exceeds the installed interface capabilities.

SF250-48HP-K9-EU identifies a 250 Series Fast Ethernet smart switch: 48 denotes its access-port count, and HP identifies the PoE+ configuration with a shared 195W allowance. EU is the regional ordering suffix used for the EU and other specified markets. K9 remains part of the complete order code.
SF250-48HP-K9-EU supports an HTTP/HTTPS web interface, full or menu-based CLI through SSH or Telnet, and SNMP. Network-level integration includes Smart Network Application, FindIT Network Manager, embedded FindIT Network Probe, FindIT Network Discovery Utility, and Cisco Active Advisor. Cisco Network Plug and Play supports provisioning rather than replacing local configuration access.
SF250-48HP-K9-EU reached end of sale on July 30, 2022, and its last date of support is July 31, 2027. Software maintenance ended July 30, 2023. Its replacement, CBS250-48PP-4G-EU, is also discontinued, and that replacement has no current migration product.
ORM offers SF250-48HP-K9-EU new sealed with up to 3-year extended warranty or certified refurbished with up to 1 year. Every condition has 30-day returns; terms apply. Cisco's separate limited lifetime hardware warranty is bounded by July 31, 2027, with 1-year coverage for fans and power supplies, subject to Cisco eligibility.
SF250-48HP-K9-EU replaces SLM248PT-G5, the SF200-48P 48-port Fast Ethernet PoE smart switch. That predecessor is discontinued, and the replacement relationship identifies a migration within powered Fast Ethernet access switching. Match the complete older order code when reviewing an installed estate rather than relying only on the SF200-48P model name.
SF250-48HP-K9-EU provides a shared 195W PoE allowance across 48 powered access ports, with a maximum of 30W available to an individual port. The aggregate allowance limits simultaneous delivery. Adding every endpoint's required allocation is necessary before assuming all connected powered devices can operate together.
The SF250-48HP configuration has two dedicated 1G SFP ports and two 1G copper/SFP combo ports, providing four simultaneous uplinks. Each combo pair activates only one medium. MGBSX1 supports multimode fiber to 500 m, while MGBLX1 supports single-mode fiber to 10 km; fiber links require separately ordered optics.
Yes, SF250-48HP-K9-EU supports static routing between network segments, with 32 IPv4 static routes and 16 IP interfaces. This makes its Layer 2+ capability distinct from an exclusively Layer 2 switch. Routes must be configured explicitly; the switch does not provide dynamic route exchange for automatic path discovery.
SF250-48HP-K9-EU uses an internal 100-240V AC supply in a Rack-Mount 1U chassis measuring 440 mm wide, 44 mm high, and 350 mm deep. The unit weighs 4.93 kg and uses two fans. Allow for its chassis depth, AC connection, and 0°C to 50°C operating range.
SF250-48HP-K9-EU supplies PoE+ on its 48 access ports, whereas SF250-48-K9-EU provides unpowered Fast Ethernet access. Both models are discontinued. For matching an existing installation, the powered version suits endpoints receiving Ethernet power, while the unpowered version suits devices that already have their own power source.
SF250-48HP-K9-EU has 48 Fast Ethernet access ports, while SF250-24P-K9-EU has 24. Both are discontinued powered-access models. When matching an established installation, the larger model suits a requirement for more endpoint connections in one chassis; the smaller model suits an access-port requirement that remains within 24 connections.
SF250-48HP-K9-EU has 100 Mbps access ports, whereas its historical replacement CBS250-48PP-4G-EU has Gigabit access ports. Both are discontinued, and no current migration product is available for the replacement. For existing-estate matching, the former fits Fast Ethernet endpoint requirements and the latter fits installed Gigabit access requirements.
No, the 250 Series Smart Switches do not form a hardware stack. Network-level management can discover and configure multiple switches, but that grouping does not create a shared stacking fabric. Treat each unit as an independent switch when specifying inter-switch links, management access, and replacement arrangements.
SF250-48HP-K9-EU provides 17.6 Gbps switching capacity and 13.1 Mpps forwarding performance for 64-byte packets. Its 24 Mb packet buffer is shared dynamically across ports. The switch also has 512 MB of memory and 256 MB of flash; those storage figures are separate from packet-buffer capacity.
The 250 Series Smart Switches support STP/RSTP/MSTP, LACP, 802.1X authentication, and 512 access-control rules. Eight hardware queues support traffic prioritization, including voice traffic. These controls cover loop handling, link aggregation, endpoint admission, and filtering; they do not change the physical access-port speed or increase the available endpoint power allowance.
