SG350-52MP combines 48 Gigabit PoE+ access ports with four fixed 1G uplinks in a managed Layer 2+ rack-mount 1U switch for small business networks. Two uplinks are dedicated SFP connections, and two are copper/SFP combo connections whose media share a single logical port. The Cisco 350 Series Managed Switches serve IP phones, wireless access points, surveillance cameras, and wired clients that need local traffic segmentation and endpoint power. The discontinued SG350-52P offers the same access density with a lower shared PoE allocation. An internal AC supply powers the chassis, while four fans provide active cooling. The fixed uplink configuration accepts compatible transceivers rather than removable network cards, so uplink media selection belongs on the purchase order alongside the switch condition and quantity.

104 Gbps switching capacity accommodates wire-speed, nonblocking switching across the network ports, while 77.38 Mpps forwarding is rated with 64-byte packets. 740W shared PoE capacity requires an endpoint allocation rather than unrestricted maximum draw from every powered connection. 990 static IPv4 routes and 128 IP interfaces support local routing; IPv6 routing and PBR extend traffic handling without dynamic routing protocols. SG350-52MP uses 512 MB DRAM, 256 MB flash, and a 3 MB shared packet buffer for control operations, image storage, and transient traffic queues. STP/RSTP/MSTP control Layer 2 loops, while LACP groups Ethernet links. DHCP snooping and Dynamic ARP Inspection filter unauthorized addressing behavior. The 52-port Gigabit Max-PoE Managed Switch separates voice traffic through a voice VLAN and applies QoS queueing. HTTPS and SSH provide encrypted administrative access, and dual firmware images support staged software upgrades.
Order SG350-52MP new sealed or certified refurbished; new units carry up to a 3-year extended warranty, certified refurbished units up to 1 year, and both conditions have 30-day returns, with terms applying. Certified refurbished units are inspected and bench-tested, including rated-speed links on every port, clean boot, PoE output under load on every powered port, optics bay recognition, PSU and fan status, firmware verification, and wiping to factory default. Specify condition, quantity, and required optics on the PO. Enterprise and volume purchases support PO acceptance, Net-30 for government, and RMA with advance replacement, with regional stock/RMA across the UK, EU, US, and MEA.

When an endpoint refresh mixes phones, cameras, and higher-draw devices, eight access ports can deliver 60W and the remaining powered ports can deliver 30W. Per-port capability remains subject to shared power allocation. Identify the higher-draw connections and total endpoint demand before specifying the powered-port assignments on the PO.
When several sites need the same operational configuration, text-editable configuration files and a scriptable CLI provide a repeatable staging method. CLI privilege levels 1, 7, and 15 allow differentiated administration. Identify the required administrator roles and configuration baseline, then specify identical hardware conditions and quantities before issuing the purchase order.
When a replacement unit must be staged before entering service, port mirroring can copy traffic from eight source ports to one destination port within a single session. That limit determines how many test connections can be observed together. Define the capture-port layout and required staging quantity before the PO.
10G uplinks to distribution
SG350-52MP uplinks are limited to 1G. C1300-48FP-4X provides four 10G SFP+ uplinks with 48 Gigabit PoE access ports for a higher-speed uplink requirement.
Multigigabit copper access connections
SG350-52MP access ports are limited to 1G. C1300-24MGP-4X adds eight 2.5G access ports but reduces total access density to 24 ports, with 16 remaining Gigabit ports.

SG350-52MP identifies a 350 Series Gigabit Max-PoE managed switch: SG350 names the Gigabit model family, 52 denotes the total network-port configuration, and MP distinguishes the 740W Max-PoE variant. The configuration has 48 PoE+ access ports plus four uplinks, with two uplinks using shared copper/SFP connections.
SG350-52MP provides a shared 740W PoE budget across 48 powered access ports, with eight ports supporting 60W and the remaining ports supporting 30W. Those per-port limits do not mean every connection can draw its maximum simultaneously. Endpoint planning must account for the combined allocation as well as individual device requirements.
SG350-52MP supports four 1G SFP connections, comprising two dedicated SFP uplinks and two copper/SFP combo uplinks. A combo connection uses either its copper interface or its SFP interface, not both simultaneously. Compatible optics include MGBSX1 for multimode fiber to 500 m and MGBLX1 for single-mode fiber to 10 km.
SG350-52MP is managed through an HTTP/HTTPS web interface, Textview CLI over console, SSH or Telnet, and SNMP. Smart Network Application supplies network-level management, with additional integration paths including Cisco FindIT Network Manager and Cisco Active Advisor. Browser configuration offers simple and advanced modes, while the CLI supports scripts and menu-based operation.
The 350 Series provides static IPv4 routing with 990 static routes and 128 IP interfaces, plus IPv6 routing and PBR. Routed interfaces can be physical ports, link aggregation groups, VLAN interfaces, or loopback interfaces. Static routing requires administratively maintained next-hop information rather than dynamic route exchange between neighboring devices.
SG350-52MP uses an internal 100-240V AC supply and reaches 858W worst-case consumption with PoE at 110V AC. The corresponding figure at 220V AC is 833W. The fixed supply does not provide a second internal redundant PSU option, so electrical planning must include the switch chassis and its powered endpoints.
SG350-52MP is discontinued: end of sale was October 30, 2021, software maintenance ended October 30, 2022, and Cisco support ends October 31, 2026. The current migration model is C1300-48FP-4G, following the intermediate CBS350-48FP-4G-NA, which also ended sale on October 29, 2024.
SG350-52MP replaces SG300-52MP-K9-AU, SG300-52MP-K9-EU, SG300-52MP-K9-NA, and SG300-52MP-K9-UK in their corresponding regional versions. These older 300 Series models are discontinued. For North American procurement, the matching replacement ordering name is SG350-52MP-K9-NA; migration planning should distinguish replacement hardware selection from validation of the existing configuration.
SG350-52MP provides a 740W PoE budget, whereas SG350-52P provides 375W with the same access-port count. Both models are discontinued. SG350-52MP fits replacement orders requiring the larger shared power allocation; SG350-52P addresses like-for-like legacy needs where the smaller allocation matches the connected endpoint load.
SG350-52MP has 48 Gigabit PoE+ access ports, whereas SG350-28MP has 24. Both models are discontinued and retain fixed 1G uplink connections. SG350-52MP addresses higher-density legacy replacements; SG350-28MP fits replacement orders for an existing 24-port installation without specifying unused access capacity.
C1300-48FP-4G provides four 1G SFP uplinks, while SG350-52MP has two dedicated 1G SFP uplinks and two shared copper/SFP uplinks. SG350-52MP supports like-for-like replacement when copper uplink flexibility matters; C1300-48FP-4G is the current migration model for buyers specifying four fiber uplink connections.
ORM Systems offers SG350-52MP new sealed or certified refurbished, with up to a 3-year extended warranty on new units and up to 1 year on certified refurbished units. Returns are available for 30 days in either condition; terms apply. Cisco's limited lifetime hardware warranty remains entitlement-dependent and ends October 31, 2026.
