SG350X-24MP-K9-NA combines 24 Gigabit PoE+ access ports with four fixed 10G uplinks in a managed Layer 2+ switch. Two uplinks are dedicated SFP+ ports; the other two offer shared copper or SFP+ connections, with one medium active per combo port. The full-width 1U chassis belongs to the Cisco 350X Series and serves small-business networks connecting IP phones, wireless access points and surveillance cameras. Fixed uplinks avoid a separate network-module purchase, while copper and fiber connection options accommodate different distribution connections. The discontinued SG350X-24P-K9-NA is the nearest lower-power sibling, carrying a 195W PoE budget. This model provides the higher-power configuration without changing the access-port count or uplink arrangement.

128 Gbps switching capacity accommodates the built-in access and uplink interfaces, while 95.23 Mpps forwarding handles minimum-size Ethernet packets. 382W of shared PoE power must cover the connected endpoints collectively; four selected ports support 60W, and the remaining powered ports support 30W each. Static IPv4 and IPv6 routing provide inter-VLAN connectivity without dynamic routing. The IPv4 limit is 990 static routes across 128 IP interfaces. SG350X-24MP-K9-NA carries 512 MB of memory and 256 MB of flash for system operation and image storage. A dynamically shared 1.5 MB packet buffer absorbs traffic bursts, and the MAC table accommodates 16000 entries. The SG350X-24MP supports STP, RSTP, MSTP and LACP for loop control and link aggregation. Browser management, a console connection and remote CLI access provide configuration paths. Two fans cool the chassis, and 468.8W maximum consumption including PoE establishes the upper electrical load for power planning.
ORM Systems supplies SG350X-24MP-K9-NA new sealed or certified refurbished, with up to 3-year extended warranty on new units, up to 1 year on certified refurbished units, and 30-day returns on every condition; terms apply. Certified refurbished units are inspected and bench-tested, with PoE output verified under load on every powered port, rated-speed port links checked, firmware verified and configuration wiped to factory default. Request a quote specifying quantity, condition and required uplink accessories; Cisco's limited lifetime hardware warranty and applicable service end October 31, 2026. For enterprise and volume orders, PO is accepted, Net-30 is available for government, and RMA includes advance replacement, with regional stock and RMA across the UK, EU, US and MEA.

An existing stack requiring another member can use ring or chain topology with automatic member numbering. Cross-stack link aggregation is supported, so the purchase must align with the existing logical configuration rather than only the required endpoint connections. Confirm topology, member numbering and cross-stack aggregation settings before the PO.
Branch equipment purchases requiring centralized provisioning can use Cisco Network Plug and Play with Cisco PnP Connect. DHCP-based automatic configuration and secure configuration transfer support repeatable installation workflows. Before the PO, specify the provisioning method and confirm how each unit will receive its initial configuration at the destination site.
Staging purchases requiring configuration reuse can use text-editable configuration files and the front-panel USB Type A slot for image and configuration transfer. Dual images are supported for firmware upgrades. Specify the approved firmware image, staging configuration and USB transfer procedure before releasing the equipment purchase order.
Multigigabit speed on access ports
The access interfaces stop at 1GbE; 10G connectivity is confined to the uplinks. Endpoints requiring native 2.5G or 5G access need different switch hardware.
60W power on every access port
Only four powered access ports support 60W, while the remaining powered ports support 30W. A deployment requiring 60W on every connection exceeds this configuration.
Cisco service beyond October 2026
Cisco service ends October 31, 2026. For a forward migration rather than an installed-base replacement, specify C1300-24FP-4X instead of the discontinued intermediate CBS350-24FP-4X-NA.

SG350X-24MP-K9-NA identifies the Gigabit 350X model with 24 PoE+ access ports, a 382W power budget and Americas regional ordering. SG350X identifies the model family, 24 identifies the access-port count, and MP selects this powered configuration. NA covers the United States, Canada, Mexico and additional Latin American markets.
SG350X-24MP-K9-NA supports HTTP/HTTPS browser management, console CLI, remote CLI over SSH or Telnet, and SNMP. Additional management paths include Smart Network Application, FindIT Network Manager with the embedded FindIT Network Probe, the FindIT Network Discovery Utility and Active Advisor. The browser interface includes simple and advanced configuration modes.
SG350X-24MP-K9-NA is discontinued, with end-of-sale on October 30, 2021 and last support on October 31, 2026. Software maintenance ended October 30, 2022. Its immediate replacement, CBS350-24FP-4X-NA, is also discontinued. The forward migration chain continues to C1300-24FP-4X, rather than stopping at the older Cisco Business model.
ORM Systems offers SG350X-24MP-K9-NA new sealed or certified refurbished, with up to 3-year extended coverage for new units and up to 1 year for refurbished units. Returns are 30 days for either condition; terms apply. Cisco's limited lifetime hardware warranty and applicable service end October 31, 2026.
SG350X-24MP-K9-NA replaces the discontinued SF550X-24MP-K9-NA, which reached end-of-sale on June 18, 2020. The older model provides 24 Fast Ethernet access ports, while this replacement provides Gigabit access. The predecessor's Cisco support ended June 30, 2025; this replacement is also discontinued and has its own support cutoff.
SG350X-24MP-K9-NA provides a shared 382W PoE budget across 24 powered access ports. Four selected ports support 60W, and the remaining powered ports support 30W each. Those per-port limits do not mean every port can deliver its maximum simultaneously; the combined endpoint allocation must remain within the shared budget.
The 350X SG350X-24MP model provides four 10G uplinks: two dedicated SFP+ ports and two copper/SFP+ combo ports. Each combo permits only one active medium. Supported optical choices include SFP-10G-SR= for multimode fiber and SFP-10G-LR= for single-mode fiber. Specify the medium, reach and separately ordered optics for each connection.
Cisco 350X hardware stacking supports four members using 10G copper or fiber interconnects. Ring and chain arrangements are available, and hybrid stacks can mix SG350X, SG350XG and SX350X models. Supported copper interconnect choices include SFP-H10GB-CU1M=, SFP-H10GB-CU3M= and SFP-H10GB-CU5M=; select lengths to match the physical stack layout.
SG350X-24MP-K9-NA includes static IPv4 and IPv6 routing, giving this configuration Layer 2+ capability. IPv4 supports 990 static routes and 128 IP interfaces; IPv6 supports 245 static routes and 106 interfaces. Routing interfaces can use physical ports, link aggregation groups, VLAN interfaces or loopback interfaces, without adding dynamic routing.
SG350X-24MP-K9-NA provides a 382W PoE budget, while SG350X-24P-K9-NA provides 195W. Both configurations have 24 powered Gigabit access ports and are discontinued. The MP configuration suits an installed-base replacement requiring the larger shared power allocation; the P configuration corresponds to deployments whose endpoint loads fit the smaller budget.
SG350X-48MP-K9-NA provides 48 powered Gigabit access ports, while SG350X-24MP-K9-NA provides 24. Both models are discontinued. The 24-port configuration suits replacement requirements matching a smaller endpoint count; the 48-port configuration corresponds to an existing installation requiring twice the access-port density. Match the installed configuration rather than treating either as a forward migration destination.
C1300-24FP-4X provides four 10G SFP+ uplinks, while SG350X-24MP-K9-NA divides its four 10G uplinks between two dedicated SFP+ ports and two copper/SFP+ combos. The discontinued 350X configuration corresponds to replacements retaining copper uplink requirements. C1300-24FP-4X is the forward migration destination for buyers specifying an all-SFP+ uplink arrangement.
