SG250-50P-K9-EU is a smart-managed Layer 2+ switch with 48 Gigabit Ethernet PoE+ access ports and two fixed Gigabit copper/SFP combo uplinks. Each combo connection uses either its copper interface or its SFP interface, not both simultaneously. The 1U rack-mount chassis belongs to the Cisco 250 Series Smart Switches family and connects small-business computers, IP phones, wireless access points, and surveillance endpoints. Static routing provides communication between network segments without adding a dynamic routing tier. The discontinued SG250-50HP-K9-EU sibling has a smaller 192W endpoint power budget, making the power allocation the principal difference between these two configurations. This model retains Gigabit uplinks rather than providing a 10G connection to distribution.
SG250-50P-K9-EU price is $1,328.25. SG250-50P-K9-EU is in stock and available for next-day dispatch. (terms applied)

100 Gbps switching capacity provides nonblocking forwarding across the port set. 74.41 Mpps forwarding performance applies to 64-byte packets, distinguishing packet-processing capacity from bandwidth. 375W of shared PoE power must cover the combined allocation to connected powered devices. Static IPv4 routing supports 32 routes and 16 IP interfaces, so route planning must remain within those limits. SG250-50P-K9-EU carries 512 MB of memory and 256 MB of flash for its embedded software and configuration. A dynamically shared 24 Mb packet buffer serves the ports collectively. STP/RSTP/MSTP controls Layer 2 topology, while LACP supports aggregated connections. HTTPS secures browser-based configuration, and SSH provides encrypted remote access. Four fans provide active cooling rather than silent operation. 481.9W maximum consumption, including PoE at 110V input, is the figure to allow for when sizing the upstream power circuit; the corresponding maximum at 220V is 468.1W.
ORM Systems supplies SG250-50P-K9-EU new sealed or certified refurbished; refurbished units are inspected and bench-tested for power-on, POST, clean boot, rated-speed port links, PoE output under load on every powered port, optics recognition, PSU and fan status, with firmware verified and configuration wiped to factory default. New units carry up to a 3-year extended warranty, certified refurbished units carry up to 1 year, and every condition includes 30-day returns; terms apply. Cisco's limited lifetime hardware warranty remains bounded by October 31, 2026. Specify condition, quantity, and regional power-cord requirements on the order; for enterprise and volume purchases, POs are accepted, government customers have Net-30 terms, and RMA with advance replacement is available across UK, EU, US, and MEA regions.

When switches are purchased for repeated branch installations, Cisco Network Plug and Play and Cisco PnP Connect provide a provisioning path. Text-editable configuration files can also be downloaded to another switch. Specify the provisioning workflow, configuration ownership, and staging requirements before the purchase order.
When a switch is being purchased for troubleshooting or predeployment validation, port mirroring can send traffic from four source ports to one destination port. VLAN mirroring offers a separate capture option. Identify the analyzer connection, capture sources, and staging configuration before ordering the hardware.
When several business locations need a common management workflow, FindIT Network Manager can use the embedded FindIT Network Probe without a separate probe appliance. Smart Network Application provides network-level discovery and configuration. Specify the management application, administrative access, and site configuration responsibilities before issuing the purchase order.
10G uplinks to distribution
The fixed combo uplinks operate at 1G, not 10G. C1200-48P-4X provides 48 Gigabit PoE access ports with four 10G SFP+ uplinks for the faster uplink requirement.
30W on every powered port simultaneously
The shared 375W budget cannot supply 30W to all 48 powered ports simultaneously. Endpoint allocations must fit the aggregate budget rather than the individual port maximum alone.
More than 32 static IPv4 routes
IPv4 routing supports 32 static routes and 16 IP interfaces. A larger routed deployment requires a different routing platform rather than an additional software tier on this model.

SG250-50P-K9-EU identifies the Gigabit PoE model in the 250 Smart Switches family: 50 represents 48 access ports plus two combo uplinks, and P identifies the powered configuration. K9 remains part of the ordering identifier. EU selects the regional variant used for the European Union and additional listed markets.
SG250-50P-K9-EU supports HTTP/HTTPS browser management, full or menu-based CLI access over SSH or Telnet, and SNMP versions 1, 2c, and 3. Network-level options include Smart Network Application, FindIT Network Manager with an embedded FindIT Network Probe, and Cisco Active Advisor. FindIT Network Discovery Utility assists device discovery.
SG250-50P-K9-EU is discontinued, with an end-of-sale date of October 30, 2021, and a last date of support of October 31, 2026. Software maintenance ended October 30, 2022. The original replacement, CBS250-48P-4G-EU, is also discontinued; the migration chain continues to C1200-48P-4G.
ORM Systems offers SG250-50P-K9-EU new sealed with up to a 3-year extended warranty or certified refurbished with up to 1 year. Every condition has 30-day returns; terms apply. Cisco's limited lifetime hardware warranty is bounded by October 31, 2026; fans and power supplies originally carried a 1-year limited warranty.
SG250-50P-K9-EU replaces the discontinued SG200-50FP-EU, whose end-of-sale date was October 4, 2018, and last date of support was October 31, 2023. The older model's PoE budget was 370W. The replacement relationship supports legacy refresh identification, but SG250-50P-K9-EU is itself discontinued.
SG250-50P-K9-EU provides a shared 375W PoE budget across 48 powered access ports, with a maximum of 30W on an individual port. The individual maximum does not mean every port can receive that allocation simultaneously. Size the combined endpoint requirements against the shared budget before specifying the switch.
The SG250-50P supports Gigabit fiber connections using MGBSX1 for multimode fiber or MGBLX1 for single-mode fiber. MGBSX1 supports a maximum distance of 500 m, while MGBLX1 supports 10 km. Each SFP interface shares its combo port with copper, so only one interface in each pair operates at a time.
Yes, SG250-50P-K9-EU supports static IPv4 routing between network segments, with a limit of 32 static routes and 16 IP interfaces. Interfaces can be configured on physical ports, link aggregation groups, VLAN interfaces, or loopback interfaces. The switch fits the Layer 2+ classification rather than a dynamic routing configuration.
The SG250-50P uses an internal universal AC power supply accepting 100-240V AC at 50-60 Hz. The chassis does not use the external adapter arrangement of the compact models. Maximum consumption including PoE is 481.9W at 110V or 468.1W at 220V, which must be allowed for in circuit sizing.
SG250-50P-K9-EU has a 375W PoE budget, whereas SG250-50HP-K9-EU has 192W; both provide 48 Gigabit PoE+ access ports and two Gigabit combo uplinks. Both models are discontinued. The former suits legacy orders needing the larger shared power allocation, while the latter fits lower-demand endpoint allocations.
SG250-50P-K9-EU provides 48 Gigabit PoE+ access ports, while SG250-26P-K9-EU provides 24; both have two Gigabit copper/SFP combo uplinks. Both models are discontinued. The larger model fits legacy replacement orders with more endpoint connections, while the smaller model fits installations requiring fewer access ports.
SG250-50P-K9-EU has two shared Gigabit copper/SFP combo uplinks, while C1200-48P-4G has four dedicated Gigabit SFP uplinks. Both configurations provide 48 Gigabit powered access ports. SG250-50P-K9-EU fits an exact legacy replacement requirement; C1200-48P-4G is the current migration option for refresh orders requiring dedicated fiber uplinks.
