SG350-52MP-K9-EU is a Layer 2+ managed access switch with 48 Gigabit PoE+ RJ-45 ports and fixed Gigabit uplinks comprising two dedicated SFP positions and two copper/SFP combo positions. The rack-mount 1U chassis belongs to the Cisco 350 Series Managed Switches and serves small-business networks connecting IP phones, wireless access points and surveillance cameras. The Cisco SG350-52MP gives buyers a Max-PoE configuration without a removable uplink-card dependency; its uplink connectors are built into the chassis. SG350-52P-K9-EU is the closest lower-budget sibling, with 375W available to endpoints, and is also discontinued. Copper and fiber uplink media can be selected for each combo position, but its paired connectors cannot operate simultaneously.

104 Gbps switching capacity provides nonblocking forwarding across the active Gigabit interfaces, while 77.38 Mpps forwarding handles 64-byte packets at the rated switching load. 740W of shared PoE capacity requires combined endpoint allocations to remain within the available budget. Static IPv4 and IPv6 routing with PBR provides inter-VLAN forwarding without dynamic routing protocols. SG350-52MP-K9-EU carries 512 MB of memory and 256 MB of flash for configuration and firmware operation. A dynamically shared 3 MB packet buffer serves all ports; the MAC table holds 16000 addresses, and VLAN support extends to 4094 simultaneous VLANs. STP/RSTP/MSTP controls Layer 2 loops, while LACP groups links under a common aggregation policy. Eight hardware queues support traffic prioritization, and DHCP snooping, IP Source Guard and Dynamic ARP Inspection enforce endpoint binding checks. Dual software images retain separate firmware versions for maintenance. 858W worst-case consumption at 110V sets the electrical sizing requirement with PoE load included.
SG350-52MP-K9-EU is available new sealed or certified refurbished; ORM provides up to a 3-year extended warranty for new units and up to 1 year for certified refurbished units, plus 30-day returns on either condition, terms apply. Refurbished units are inspected and bench-tested for power-on, POST, rated-speed links, clean boot, loaded PoE output on every powered port, optics bay recognition, PSU status and fan status; firmware is verified and configurations are wiped to factory default. Specify condition, quantities and required optics on the PO. For enterprise and volume orders, ORM accepts POs, offers Net-30 for government and RMA with advance replacement, with regional stock and RMA across UK, EU, US and MEA.

When a rollout adds higher-draw phones, cameras or wireless endpoints, eight access ports can supply 60W PoE; the other powered ports are limited to 30W each. Endpoint power class therefore affects which port receives each connection. List each device's required wattage and assign high-draw devices to the appropriate ports before the PO.
When several offices need the same configuration, text-editable files can be downloaded to another switch and secure autoconfiguration can retrieve files through SCP. Keep site-specific addressing separate from reusable settings, and decide which configuration will be loaded during staging. Specify the configuration file and provisioning method before ordering the rollout quantity.
When a staged network change requires packet capture, port mirroring supports eight source ports feeding one destination port within a single session. That constraint determines which connections can be observed together. Identify the source interfaces, reserve the analyzer connection and specify the capture arrangement before ordering equipment for the staging bench.
10G uplinks to distribution
SG350-52MP-K9-EU uplinks are limited to 1G. C1300-48FP-4X provides 48 Gigabit access ports with four 10G SFP+ uplinks for a current replacement requiring faster uplink connections.
Dynamic routing at the access edge
SG350-52MP-K9-EU supports static IPv4 and IPv6 routing with PBR, but not dynamic routing. Automatic route exchange must remain outside this switch's role in the routing design.

SG350-52MP-K9-EU identifies a Cisco 350 Series Gigabit Max-PoE managed switch: SG350 is the Gigabit family, 52 is the total system-port count, MP identifies Max-PoE, and EU is the regional ordering suffix. The configuration has 48 powered access ports and four additional Gigabit uplink positions.
SG350-52MP-K9-EU supports browser management, Textview CLI through console or SSH/Telnet, SNMP and Smart Network Application, with integrations for Cisco FindIT Network Manager and Cisco Active Advisor. An embedded FindIT Network Probe supports network-level management, while Cisco Network Plug and Play with PnP Connect supports provisioning. Specify the management method during staging.
SG350-52MP-K9-EU provides a 740W shared PoE budget across 48 powered access ports, including eight ports capable of 60W PoE. The remaining powered ports support 30W each. Per-port ratings are not simultaneous full-load guarantees; size the combined endpoint allocation before specifying the switch for a powered-device rollout.
The Cisco SG350-52MP provides two dedicated 1G SFP uplinks and two 1G copper/SFP combo uplinks. Each combo position activates either its copper connector or its SFP cage, not both together. Choose the uplink media before specifying the required transceivers and copper patching for the purchase order.
SG350-52MP-K9-EU supports MGBSX1 for multimode fiber links up to 500 m and MGBLX1 for single-mode fiber links up to 10 km. MGBLH1 supports single-mode fiber up to 40 km. These are 1G transceivers; specify the optical distance and fiber type for each uplink.
Yes, the Cisco 350 Series supports static IPv4 and IPv6 routing plus PBR, with 990 static IPv4 routes and 128 IP interfaces. SG350-52MP-K9-EU is therefore Layer 2+ for this configuration, rather than a dynamic-routing switch. Check the route and interface requirements before assigning inter-VLAN routing duties.
SG350-52MP-K9-EU uses an internal universal AC power supply accepting 100-240V AC. Worst-case consumption with PoE reaches 858W at 110V or 833W at 220V. Those figures cover the switch and endpoint power together; use the applicable input-voltage figure when sizing the electrical feed.
Yes, SG350-52MP-K9-EU ended Cisco sales on October 30, 2021, and reaches its last date of support on October 31, 2026. Software maintenance ended October 30, 2022. The immediate replacement, CBS350-48FP-4G-EU, is also discontinued; the replacement chain now leads to C1300-48FP-4G.
SG350-52MP-K9-EU replaced SG300-52MP-K9-EU, the earlier 52-port Gigabit Max-PoE managed switch. Both identifiers are distinct hardware generations, so an upgrade order should retain the complete requested part number. SG350-52MP-K9-EU is itself discontinued; current replacement procurement follows the chain to C1300-48FP-4G rather than stopping at another discontinued generation.
SG350-52MP-K9-EU has a 740W PoE budget, while SG350-52P-K9-EU has 375W. Both models are discontinued. The Max-PoE version suits legacy replacement requirements with higher combined endpoint draw; the lower-budget version suits an existing configuration whose allocated endpoint demand fits its smaller power budget.
SG350-52MP-K9-EU provides 48 powered Gigabit access ports, while SG350-28MP-K9-EU provides 24. Both models are discontinued. The larger model suits same-generation replacement orders requiring higher access-port density; the smaller model suits an existing installation with fewer powered connections. Specify the required access-port count before ordering.
C1300-48FP-4G has four dedicated 1G SFP uplinks, while SG350-52MP-K9-EU combines two dedicated SFP uplinks with two copper/SFP combo uplinks. The discontinued SG350 model suits exact-match legacy sparing; C1300-48FP-4G is the current successor for replacement orders that do not require copper combo uplinks.
The Cisco SG350-52MP occupies one rack unit and measures 440 mm wide, 44 mm high and 350 mm deep. The chassis weighs 3.83 kg and uses four fans. Check rack depth, airflow clearance and mounting-kit inclusion when specifying the equipment and accessories on the order.
ORM offers SG350-52MP-K9-EU new sealed or certified refurbished, with up to a 3-year extended warranty for new units and up to 1 year for refurbished units. Both conditions include 30-day returns; terms apply. Cisco's limited lifetime hardware warranty is separate, and Cisco service and warranty support end October 31, 2026.
