SG350-52P-K9-EU is a managed Layer 2+ access switch with 48 Gigabit Ethernet PoE+ downlinks and four fixed Gigabit uplinks: two dedicated SFP ports and two copper/SFP combo ports. Each combo uplink operates through its copper connector or its SFP cage, not both simultaneously. The full-width 1U rack-mount chassis belongs to the Cisco 350 Series and connects small-business workstations alongside powered phones, wireless access points, and cameras. The discontinued SG350-52-K9-EU is the nearest non-PoE sibling, retaining the access-port density and uplink arrangement without endpoint power. Cisco Small Business switching features include voice VLAN handling, traffic prioritization, and guest traffic segmentation for networks carrying several endpoint types.

104 Gbps switching capacity enables nonblocking forwarding across the built-in interfaces. 77.38 Mpps forwarding at 64-byte packets defines the small-packet throughput limit. 375W shared PoE power requires allocation across connected devices rather than assuming every powered port can operate at its individual ceiling. 990 static IPv4 routes support manually configured paths, while PBR selects next hops using IPv4 or IPv6 access control rules. SG350-52P-K9-EU provides 512 MB of memory and 256 MB of flash for control operations and software storage, alongside a 3 MB packet buffer shared across its ports. STP/RSTP/MSTP control bridged loops, and LACP groups physical links. DHCP snooping, IP Source Guard, and Dynamic ARP Inspection provide address-validation controls that require appropriate trusted-port settings. Routing uses static paths rather than dynamically learned routes. 440W maximum consumption with PoE provides the upper published electrical load for sizing the switch's AC circuit and backup power allocation.
Specify SG350-52P-K9-EU in new sealed or certified refurbished condition, with condition and quantity recorded on the purchase order. Certified refurbished units are inspected and bench-tested, including PoE output verification under load on every powered port; firmware is verified and configurations are wiped to factory default. ORM warranties are up to 3-year extended for new units and up to 1 year for certified refurbished units; every condition has 30-day returns, terms apply, while Cisco's separate limited lifetime coverage is bounded by October 31, 2026. Enterprise and volume orders support PO acceptance, Net-30 for government, and RMA with advance replacement, with regional stock/RMA across UK, EU, US, and MEA.

A site adding separate user, voice, and guest networks needs an interface plan before enabling local gateways. The switch supports 128 IP interfaces, with Layer 3 interfaces configurable on physical ports, link aggregation groups, VLANs, or loopbacks. Specify the required interfaces and upstream routing responsibilities before the PO.
A buyer standardizing several existing sites needs repeatable configuration handling rather than independent manual setup at every location. Text-editable configuration files can be downloaded to another switch, and CLI privilege levels 1, 7, and 15 separate administrative access. Specify the configuration baseline and administrator access requirements before ordering quantities.
A staging lab investigating endpoint traffic needs a defined capture arrangement before equipment arrives. Port mirroring supports eight source ports feeding one destination port, with a single mirroring session. Multiple simultaneous independent captures exceed that arrangement. Specify the capture destination and source-port selection in the lab equipment order.
10G uplinks to distribution
SG350-52P-K9-EU uplinks operate at 1Gbps. C1300-48P-4X retains 48 Gigabit access ports and provides four 10G SFP+ uplinks for buyers requiring faster distribution connections.
Dynamically learned routing paths
SG350-52P-K9-EU supports static IPv4 routing and PBR. Networks requiring automatic route learning cannot use manually configured static routes as a substitute for that requirement.
Fanless operation in occupied rooms
SG350-52P-K9-EU uses three fans, with acoustic output of 41.2dB at 0°C to 25°C. The chassis therefore does not satisfy a passive-cooling requirement.

SG350-52P-K9-EU identifies a Gigabit Cisco 350 managed PoE model: 52 system ports comprise 48 access ports and four uplinks, while P identifies the powered version. EU selects the regional ordering variant used in the European Union and several additional markets; the regional suffix does not describe a different port configuration.
The Cisco 350 Series supports an HTTP/HTTPS web interface, CLI through the console or SSH/Telnet, and SNMP versions 1, 2c, and 3. Network-level tools include FindIT Network Manager with an embedded probe and Cisco Active Advisor. Specify the intended administration method and management-access controls before deploying the switch.
SG350-52P-K9-EU provides a 375W shared PoE budget across 48 powered access ports. Eight ports support 60W each, while the other powered ports support 30W each, subject to the total budget. The individual port ceilings cannot all be supplied simultaneously; size the order using the connected devices' actual power requirements.
SG350-52P-K9-EU has two dedicated 1G SFP uplinks and two 1G copper/SFP combo uplinks. Each combo connection uses one medium at a time. Supported fiber transceivers include MGBSX1 for multimode fiber and MGBLX1 for single-mode fiber; specify the transceiver PID, fiber type, and remote interface on the purchase order.
The Cisco 350 Series provides static IPv4 routing with 990 routes, IPv6 routing, and PBR for directing traffic to selected next hops. The interface allowance is 128 IP interfaces. A routed deployment needs an explicit gateway and static-route plan; these functions do not provide automatic learning of remote network routes.
Yes, SG350-52P-K9-EU is a full-width 1U rack-mount switch measuring 440 mm wide, 44 mm high, and 350 mm deep. The chassis weighs 3.81 kg and uses three fans. Check rack depth, cable clearance, and airflow arrangements before specifying the installation location and required quantity.
SG350-52P-K9-EU reached end of sale October 30, 2021, and its last date of Cisco support is October 31, 2026. The original replacement, CBS350-48P-4G-EU, is also discontinued; the current successor is C1300-48P-4G. Remaining new sealed inventory does not restart the original switch's lifecycle or extend its support deadline.
SG350-52P-K9-EU replaced the discontinued SG300-52P-K9-EU Gigabit PoE managed switch. Buyers maintaining an older installation should review endpoint power allocation, uplink media, and configuration requirements before treating the replacement as interchangeable. The SG350 model is itself discontinued, so a new hardware refresh should follow the replacement chain to C1300-48P-4G.
SG350-52P-K9-EU is offered new sealed or certified refurbished. ORM provides up to a 3-year extended warranty for new units and up to 1 year for refurbished units, plus 30-day returns on every condition, terms apply. Cisco's separate limited lifetime hardware warranty is bounded by its October 31, 2026 last support date.
SG350-52P-K9-EU supplies PoE+ on its 48 access ports, while SG350-52-K9-EU supplies no endpoint power. Both have Gigabit access connectivity and the same dedicated SFP and combo uplink arrangement. Both models are discontinued; the powered version suits existing powered-endpoint requirements, while the non-PoE version suits separately powered devices.
SG350-52P-K9-EU uses an internal AC power supply, while SG350-10P-K9-EU uses an external AC adapter. The latter is also a smaller configuration with eight access ports, so it is not a same-density substitute. Both are discontinued; the larger model suits rack-based retention orders, while the smaller model suits existing compact installations.
C1300-48P-4G has four dedicated 1G SFP uplinks, while SG350-52P-K9-EU has two dedicated SFP uplinks and two copper/SFP combo uplinks. C1300-48P-4G is the current successor in the replacement chain. The newer model suits orders requiring four dedicated fiber uplinks; the discontinued SG350 model suits retention requirements involving its combo connections.
