SG350X-24P-K9-EU provides 24 Gigabit Ethernet access ports with PoE+ in a managed, Layer 2+ switch for small-business networks. Four fixed 10G uplinks combine two dedicated SFP+ cages with two copper/SFP+ combo connections, with only one medium active per shared position. The full-width, 1U chassis belongs to the Cisco 350X Series and connects computers alongside powered phones, wireless access points, and cameras. Four access ports also support compatible 60W PoE endpoints, subject to the shared power allocation. The discontinued SG350X-24MP-K9-EU increases that allocation to 382W without changing the access-port count. The choice between these legacy models depends on endpoint power requirements rather than additional wired connections.

128 Gbps switching capacity accommodates the access and uplink interfaces, while 95.23 Mpps forwarding performance applies to 64-byte packets. 195W of shared PoE power limits the combined endpoint allocation rather than guaranteeing maximum output from every powered port simultaneously. Static IPv4 and IPv6 routing provide inter-network forwarding without a dynamic-routing feature set, with ceilings of 990 IPv4 routes and 245 IPv6 routes. SG350X-24P-K9-EU uses 512 MB of DRAM for system operations and 256 MB of flash for firmware storage. Packet buffering on the Cisco SG350X-24P totals 1.5 MB, dynamically shared across the ports. A 16000-entry MAC table supports address learning, while 4094 active VLANs provide traffic segmentation. STP/RSTP/MSTP support loop control, and LACP provides link aggregation. Eight hardware queues support traffic scheduling. Browser-based administration is complemented by command-line access over SSH, Telnet, or the local console, giving administrators both graphical configuration and terminal-based maintenance paths.
Order SG350X-24P-K9-EU in new sealed or certified refurbished condition, and confirm the condition and quantities before placing the PO. Certified refurbished units are inspected and bench-tested, with PoE output verified under load on every powered port, firmware verified, and configurations wiped to factory default. ORM's warranty is up to 3-year extended for new units and up to 1 year for certified refurbished units, with 30-day returns on every condition; terms apply. POs are accepted, government buyers can use Net-30, and enterprise or volume requirements can include RMA with advance replacement across the UK, EU, US, and MEA.

Replacing an existing SF550X-24P-K9-EU requires matching the replacement to the installed configuration rather than matching the chassis alone. SG350X-24P-K9-EU is its named migration model, while the older switch reached end of sale on June 18, 2020. Review the existing configuration, endpoint inventory, and replacement quantities before specifying the PO.
Expanding an existing hardware stack requires a connection and cable plan before adding another chassis. The 350X supports ring and chain arrangements under a single management IP address, with link aggregation available between members. Specify SFP-H10GB-CU1M= for a supported 1 m direct-attach connection, and confirm the intended member connections before the PO.
Preparing replacement stock before a maintenance window requires a firmware and configuration plan rather than an unopened spare alone. The switch retains two firmware images and supports upgrade methods including the web interface, TFTP, and SCP. Specify the staging image, console access requirements, and configuration acceptance checks before releasing the PO.
Cisco support beyond October 2026
Cisco support ends October 31, 2026. C1300-24P-4X is the current migration endpoint; the intermediate CBS350-24P-4X-EU replacement is also discontinued and should not be treated as current-generation hardware.
Every port delivering 30W simultaneously
The shared 195W allocation cannot supply 30W to all 24 powered access ports simultaneously. Size the simultaneous endpoint load before selecting this power configuration.
Multigigabit connections for access devices
Access ports stop at 1GbE. C1300-24MGP-4X provides eight 2.5GbE access ports and sixteen Gigabit access ports, rather than multigigabit connectivity on every access port.

SG350X-24P-K9-EU identifies the EU-region Cisco 350X Gigabit PoE stackable model with 24 access ports. SG350X is the model family, 24 is the access-port count, P identifies the powered version, and EU is the regional ordering suffix. Retain K9 when matching the complete orderable part number.
SG350X-24P-K9-EU is managed through an HTTP/HTTPS web interface, CLI over SSH or Telnet, the RJ-45 console, and SNMP. Network-level administration also includes Smart Network Application, FindIT Network Manager, and an embedded FindIT Network Probe; FindIT Network Discovery supports discovery. Select the management method and access controls before staging.
195W is the shared PoE budget for SG350X-24P-K9-EU across 24 powered Gigabit ports. Four ports support 60W PoE; the other powered ports support 30W each. The shared budget remains the binding limit, so the number of endpoints that can run together depends on their allocated power.
SG350X-24P-K9-EU has four fixed 10G uplink positions: two dedicated SFP+ ports and two copper/SFP+ combo ports. Each combo position activates only one medium at a time. SFP-10G-SR= supports multimode fiber and SFP-10G-LR= supports single-mode fiber; confirm the selected media and both link ends before ordering.
Cisco 350X hardware stacking supports a maximum of four members managed as one system. SG350X, SG350XG, and SX350X models can share a stack using 10G copper or fiber interconnects in ring or chain arrangements. SFP-H10GB-CU1M= is a supported 1 m direct-attach option; allocate interconnect ports when planning the stack.
Static IPv4 and IPv6 routing are available on the Cisco SG350X-24P, with limits of 990 IPv4 static routes and 245 IPv6 static routes. The switch supports 128 IPv4 interfaces and 106 IPv6 interfaces. These are static-routing capabilities rather than a dynamic-routing feature set, so retain an appropriate routing design upstream.
SG350X-24P-K9-EU replaces SF550X-24P-K9-EU, the older 24-port 10/100 PoE stackable switch. That predecessor reached end of sale on June 18, 2020, and Cisco service ended June 30, 2025. Replacement planning should compare the existing configuration and endpoint requirements rather than treat the old and new order codes as interchangeable.
SG350X-24P-K9-EU reached end of sale on October 30, 2021, and its last date of Cisco support is October 31, 2026. The immediate replacement, CBS350-24P-4X-EU, is also discontinued. Its migration model is C1300-24P-4X, so distinguish legacy sparing from a purchase intended to move to the current generation.
SG350X-24MP-K9-EU provides a 382W PoE budget, compared with 195W for SG350X-24P-K9-EU. Both retain 24 powered Gigabit access ports, so this comparison concerns the endpoint power total rather than additional connections. Both models are discontinued; the MP version fits heavier legacy power allocations, while the P version fits smaller allocations.
SG350X-48P-K9-EU has 48 Gigabit access ports, while SG350X-24P-K9-EU has 24. This is a density comparison for buyers maintaining the same legacy switch family, not a recommendation to start a new lifecycle. Both models are discontinued; the 48-port version serves larger connection counts, while the 24-port version serves smaller cabinets.
C1300-24P-4X uses four 10G SFP+ uplinks, while SG350X-24P-K9-EU combines two dedicated SFP+ uplinks with two copper/SFP+ combo positions. The discontinued SG350X model fits legacy connections requiring that copper option; C1300-24P-4X is the current migration endpoint for buyers standardizing on the four SFP+ uplink configuration.
New sealed and certified refurbished SG350X-24P-K9-EU units have ORM warranties of up to 3-year extended and up to 1 year, respectively, with 30-day returns on every condition; terms apply. Cisco's separate limited lifetime hardware warranty, where applicable, is bounded by the last date of support, October 31, 2026.
