SG350-28MP is a higher-budget managed Gigabit PoE+ switch with 24 copper access ports and four fixed Gigabit uplink connections: two dedicated SFP slots and two copper/SFP combo ports. The Layer 2+ configuration uses a 1U rack-mount chassis for small-business networks. Cisco 350 Series Managed Switches connect computers and printers alongside powered IP phones and wireless access points. Each combo connection uses either its copper interface or its fiber interface, not both simultaneously. The discontinued SG350-28P sibling carries a 195W PoE budget for legacy installations with lower aggregate endpoint demand. The Cisco Small Business feature set also supports automatic voice VLAN assignment and traffic prioritization for communications endpoints sharing the physical network.

56 Gbps switching capacity provides nonblocking forwarding across the fixed interfaces. 41.66 Mpps forwarding handles the published 64-byte packet workload. 382W of shared PoE capacity requires endpoint power allocation rather than simultaneous maximum draw across every powered connection. 990 static IPv4 routes and 128 IP interfaces support local routing, while PBR directs selected traffic to specified next hops. SG350-28MP uses 512 MB of memory and 256 MB of flash for its operating configuration and firmware. A dynamically shared 1.5 MB packet buffer serves the aggregate port traffic, and the MAC table accommodates 16000 entries. Support for 4094 VLANs provides segmentation within the available interface limits. STP, RSTP, and MSTP control switching loops; LACP supports aggregated links. DHCP snooping and Dynamic ARP Inspection add checks on endpoint addressing and bindings. 451.2W worst-case consumption with PoE at 220V provides a published reference for sizing the electrical circuit and backup power allocation.
Specify SG350-28MP as new sealed or certified refurbished, and include the regional ordering PID, transceivers, and quantity on the PO. Certified refurbished units are inspected and bench-tested; every port links at rated speed, PoE output is verified under load on every powered port, and firmware is verified before configuration is wiped to factory default. ORM warranties are 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 orders have Net-30 terms, and RMA includes advance replacement across UK, EU, US, and MEA for enterprise and volume procurement.

In a 50-seat branch office, IT teams deploy the SG350-28MP-16 (24 10/100/1000 PoE+ ports, 2 Gigabit copper/SFP combos, 2 SFP uplinks) to power IP phones and Wi-Fi 6 access points while using VLANs and advanced QoS to segment voice, data and guest traffic. Dual SFP ports create redundant fiber uplinks to the data center, ensuring sub-millisecond failover and end-to-end PoE budget control. The result is simplified cabling, centralized management via Cisco’s GUI, crystal-clear voice calls and 99.99% uptime.
A boutique hotel network leverages the SG350-28MP-16’s 10/100/1000 PoE+ ports plus 2 copper/SFP combos and 2 dedicated SFP ports to build a fiber backbone between floors. PoE+ powers IP cameras and door controllers, while VLANs isolate guest Wi-Fi, security surveillance and administrative systems. Layer 3 static routing and link aggregation boost resilience. Guests enjoy seamless connectivity, operations maintain strict traffic isolation, and IT reduces rack space and maintenance overhead.
A K-12 campus deploying 200+ IP cameras and digital displays uses the SG350-28MP-16’s 16 PoE+ ports for 30W-per-port power and its 2 Gigabit copper/SFP combo plus 2 SFP ports for fiber uplinks to the MDF. Access control lists and storm control protect video streams, while SNMP-based monitoring accelerates issue resolution. Outcome: centralized PoE management, uninterrupted HD video feeds, enhanced campus safety and a scalable switch architecture that grows with future classroom technology needs.
When an office requires powered endpoints to follow business hours, time-based PoE can enable or disable power on a user-defined schedule. Treat shutdown behavior as an endpoint requirement, particularly for devices expected to remain active outside occupancy hours. Specify which connections must stay powered and approve the schedule before the PO.
When several offices need a repeatable configuration, text-editable configuration files and secure file transfer support a shared staging process. Separate site-specific settings from the common configuration before units leave staging. Specify the configuration acceptance checks, management access requirements, and responsibility for loading each site's settings before placing the purchase order.
When a lab or staging purchase must support traffic inspection, port mirroring can send traffic from eight source ports to one destination port within a single session. Reserve the analyzer connection rather than assigning every available connection to endpoints. Confirm the required capture scope and destination-port allocation before the PO.
10G uplinks to distribution switches
SG350-28MP uplinks operate at 1G and cannot provide 10G connections. C1300-24FP-4X retains 24 Gigabit powered access ports while providing four 10G SFP+ uplinks.
Cisco support beyond October 2026
SG350-28MP reaches its last date of Cisco support on October 31, 2026. C1300-24FP-4G is the current migration model after the discontinued intermediate replacement.

SG350-28MP identifies a 350 Series Gigabit managed switch with 28 network connections and the higher-budget powered configuration. SG350 identifies the Gigabit family, 28 covers 24 access connections plus four uplink connections, and MP distinguishes the 382W PoE configuration. The North American ordering PID is SG350-28MP-K9-NA.
SG350-28MP supports browser management over HTTP/HTTPS, console CLI, remote CLI over SSH or Telnet, and SNMP. Additional management integrations include Smart Network Application, Cisco FindIT Network Manager with an embedded probe, Cisco Active Advisor, and Network Plug and Play. Browser configuration offers simple and advanced modes.
SG350-28MP is discontinued, with end of sale on October 30, 2021, and last support on October 31, 2026. Software maintenance ended October 30, 2022. The North American replacement chain passes through discontinued CBS350-24FP-4G-NA to current C1300-24FP-4G. Purchasing new sealed stock does not restart Cisco's lifecycle milestones.
ORM Systems offers SG350-28MP new sealed with up to a 3-year extended warranty or certified refurbished with up to a 1-year warranty. Both conditions have 30-day returns; terms apply. Cisco's platform warranty is limited lifetime, bounded by October 31, 2026 support. Refurbished units are inspected, bench-tested, firmware verified, and factory-default wiped.
SG350-28MP replaces the discontinued SG300-28MP configuration; SG350-28MP-K9-NA is the named replacement for SG300-28MP-K9-NA. Regional replacements also exist for Argentina, Australia, China, the EU, and the UK ordering variants. Match the original regional PID when identifying legacy spares, rather than treating every regional order code as interchangeable.
SG350-28MP provides a shared 382W PoE budget across 24 powered access ports, including four ports supporting 60W and the remaining ports supporting 30W. These individual ceilings do not mean every port can operate at its maximum simultaneously. Sum endpoint requirements and assign high-draw devices to the appropriate connections.
The SG350-28MP configuration has two dedicated 1G SFP uplinks and two additional 1G copper/SFP combo uplinks. MGBSX1 supports multimode fiber, while MGBLX1 supports single-mode fiber. Each combo connection activates only one medium at a time. Include the selected transceiver PIDs separately when specifying fiber connections on the order.
Yes, SG350-28MP supports inter-VLAN routing through static IPv4 routes, with 990 static routes and 128 IP interfaces available. PBR provides additional next-hop selection based on traffic matching. The routing configuration can use physical ports, link aggregation groups, VLAN interfaces, or loopback interfaces; size the interface plan before deployment.
SG350-28MP has a 382W shared PoE budget, while SG350-28P has 195W. Both models are discontinued. The higher-budget configuration suits legacy installations with greater aggregate endpoint demand; the lower-budget configuration suits smaller power allocations. Compare the endpoint power total before selecting stocked hardware, because individual port power limits still apply.
SG350-52MP provides 48 Gigabit powered access ports, while SG350-28MP provides 24. Both are discontinued members of the 350 Series. SG350-28MP suits legacy replacement orders requiring fewer copper endpoint connections; SG350-52MP suits installations requiring twice the access-port density. Select the connection count from the endpoint schedule before specifying either configuration.
C1300-24FP-4G has four dedicated 1G SFP uplinks, while SG350-28MP has two dedicated SFP uplinks and two copper/SFP combo uplinks. SG350-28MP suits legacy replacement requirements retaining that shared-port arrangement; C1300-24FP-4G suits migration to the current Catalyst 1300 generation. The intermediate CBS350-24FP-4G-NA replacement is also discontinued.
SG350-28MP requires a 1U rack position and measures 440 mm wide, 44 mm high, and 257 mm deep, with a weight of 3.37 kg. Two cooling fans mean this configuration is not fanless. Confirm chassis clearance and airflow when assigning the rack position and preparing the installation order.
