SG250-50HP-K9-EU is a Layer 2+ smart-managed access switch with 48 dedicated 10/100/1000 PoE+ ports and two fixed Gigabit copper/SFP combo uplinks. The full-width 1U chassis belongs to Cisco 250 Series Smart Switches and connects small-business computers, phones, cameras and wireless access points. Each combo connection uses copper or fiber, not both simultaneously, so the uplink choice must match the installed cabling rather than assume separate copper and optical paths. The SG250-50HP combines powered endpoint connections with fixed uplinks instead of a removable uplink-card architecture. The discontinued SG250-50P-K9-EU offers a larger 375W PoE budget, a distinction to retain when matching legacy replacement hardware to endpoint demand.

100 Gbps switching capacity supports wire-speed, nonblocking forwarding, while 74.41 Mpps forwarding handles traffic measured with 64-byte packets. 192W of shared PoE output requires endpoint allocations to remain within the available pool rather than treating each powered connection as an independent maximum allowance. Static IPv4 routing supports communication between VLANs without a dynamic routing protocol. SG250-50HP-K9-EU carries 512 MB of memory and 256 MB of flash for its operating software and configuration, while a dynamically shared 24 Mb packet buffer serves traffic across the ports. STP/RSTP/MSTP provide spanning-tree options, and LACP supports aggregated Ethernet connections. Eight hardware queues support traffic prioritization using strict-priority or weighted round-robin scheduling. Browser configuration and a scriptable CLI provide local administrative choices, with SNMP available for network monitoring. 267.2W maximum power consumption includes PoE loading and provides the upper input-power figure for AC circuit planning; the corresponding maximum at 220V is 263.5W.
SG250-50HP-K9-EU is offered new sealed with up to 3-year extended warranty or certified refurbished with up to 1 year, with 30-day returns on either condition; terms apply. Certified refurbished units are inspected and bench-tested for power-on and POST, rated-speed links on every port, clean boot, PoE output under load on every powered port and optics bay recognition; firmware is verified and configurations are wiped to factory default. Specify the condition and regional power cord on the purchase order. ORM Systems accepts POs for enterprise and volume orders, offers Net-30 for government and RMA with advance replacement, and provides regional stock/RMA across the UK, EU, US and MEA.

When phones, wireless access points and cameras share a purchase order, endpoint power requirements determine what can run together. PoE+ output reaches 30W per powered connection, but the available pool is shared rather than a maximum allowance for every socket. List each device's requested power before sizing the order.
When an office needs communication between separate workgroups without sending every internal packet through its external router, static routing provides the required local forwarding function. The switch supports 16 IP interfaces. Map the intended subnets and interface assignments against that limit before specifying the configuration on the purchase order.
When multiple offices need a common configuration, text-editable files and SCP-based autoconfiguration support repeatable staging. CLI privilege levels 1, 7 and 15 let the configuration distinguish monitoring from administrative access. Define the baseline file, credential handling and site-specific addressing before placing a volume purchase order.
10G uplinks to distribution
Fixed uplinks stop at 1G, with no removable uplink card for higher speeds. C1200-48P-4X provides four 10G SFP+ uplinks alongside 48 Gigabit access ports.
More than 30W per endpoint
PoE+ output stops at 30W per powered port. Endpoints requiring a higher per-port allocation need another power source or switch; the shared budget cannot raise that ceiling.
Dynamic routing between network segments
IPv4 routing is limited to static entries, with 32 routes and 16 IP interfaces. Networks requiring dynamic routing need a different switching or routing solution.

SG250-50HP-K9-EU identifies a Cisco 250 Series Gigabit PoE+ smart switch: SG250 names the Gigabit family, 50 identifies the total port count, and HP identifies the 192W powered configuration. K9 remains part of the complete product identifier; EU selects the regional ordering version for Europe and other supported markets.
SG250-50HP-K9-EU is managed through an HTTP/HTTPS web interface, a full or menu-based CLI over SSH/Telnet, and SNMP versions 1, 2c and 3. Network-level options include Smart Network Application, FindIT Network Manager with an embedded FindIT Network Probe, FindIT Network Discovery Utility and Cisco Active Advisor. Network Plug and Play supports provisioning.
SG250-50HP-K9-EU reached end of sale on October 30, 2021, and reaches its last date of support on October 31, 2026. Routine software maintenance ended on October 30, 2022. New sealed inventory does not restart these milestones, so purchasing plans must account for the remaining service window.
ORM Systems offers SG250-50HP-K9-EU new sealed with up to 3-year extended warranty or certified refurbished with up to 1 year. Both conditions have 30-day returns; terms apply. Cisco's separate limited lifetime hardware warranty, including 1-year fan/power-supply coverage, remains bounded by eligibility and the October 31, 2026 last support date.
SG250-50HP-K9-EU replaces SLM2048PT-EU, the discontinued SG 200-50P 50-port Gigabit PoE Smart Switch. Buyers maintaining that older equipment can use the replacement relationship to identify the intended successor, but must still match endpoint power demand, uplink media and regional power connections before specifying a legacy replacement.
SG250-50HP-K9-EU provides a shared 192W PoE budget across 48 powered ports, with PoE+ output reaching 30W on an individual port. The per-port maximum is not available simultaneously on every powered connection. Size the aggregate endpoint allocation against the shared budget before assigning phones, cameras or wireless access points.
Cisco SG250-50HP supports two fixed 1G copper/SFP combo uplinks, with only one medium active on each paired connection. Compatible optics include MGBSX1 for multimode fiber to 500 m and MGBLX1 for single-mode fiber to 10 km. These optics are separate purchase items, not additional Ethernet interfaces.
Yes, SG250-50HP-K9-EU supports IPv4 static routing between network segments, with 32 static routes and 16 IP interfaces. Layer 3 interfaces can use a physical port, link aggregation group, VLAN interface or loopback interface. This static-routing capability places the switch in the Layer 2+ category rather than dynamic-routing access switching.
Cisco SG250-50HP occupies 1U in a full-width rack installation and measures 440 mm wide, 44 mm high and 350 mm deep. The chassis weighs 4.8 kg and uses two fans rather than passive cooling. Allow for connected cables and airflow when checking the cabinet layout.
SG250-50HP-K9-EU was replaced by CBS250-48PP-4G-EU, which has four dedicated 1G SFP uplinks instead of the older model's two combo uplinks. That replacement is also discontinued, having reached end of sale on October 29, 2024. The migration chain ends there without a further named migration successor.
SG250-50HP-K9-EU provides a 192W PoE budget, while SG250-50P-K9-EU provides 375W across the same number of powered access ports. Both are discontinued. The HP version matches legacy installations with lower aggregate endpoint allocations; the P version addresses existing fleets requiring the larger shared power allowance.
SG250-50HP-K9-EU uses an internal AC supply, while SG250-10P-K9-EU uses an external adapter and can also accept power through its uplinks. Both models are discontinued. The larger model fits existing rack-based replacements; the compact model serves legacy locations where power arrives from upstream networking equipment.
SG250X-48P-K9-EU provides four 10G uplinks, split between two copper connections and two SFP+ cages, while SG250-50HP-K9-EU provides two 1G combo uplinks. Both are discontinued. Existing Gigabit uplink installations match the older model's connections; legacy deployments already requiring 10G uplinks need the X model's uplink architecture.
