SG350X-24PD-K9-NA combines twenty Gigabit Ethernet access ports with four 2.5G access ports in a managed, stackable Layer 2+ switch for small-business networks. All twenty-four access connections support PoE+, while four fixed 10G uplinks provide two dedicated SFP+ cages and two copper/SFP+ combo connections. Each combo connection uses either copper or fiber at one time. The Cisco 350X Series serves powered access points, IP phones, and surveillance cameras without requiring every endpoint to use multigigabit Ethernet. A rack-mount 1U chassis places this mixed-speed configuration in a wiring closet. The discontinued SG350X-24P-K9-NA instead has a 195W PoE budget, distinguishing the lower-power legacy configuration from this model's larger allocation for powered endpoints.

140 Gbps switching capacity accommodates aggregate traffic across the access and uplink connections. 104.16 Mpps forwarding applies to 64-byte packets, so packet size matters when comparing forwarding performance. 990 IPv4 static routes define the ceiling for manually configured paths between local networks; dynamic route exchange is absent. SG350X-24PD-K9-NA carries 512 MB DRAM and 256 MB flash for running software and storing images and configuration. Packet buffering totals 3 MB shared across all ports, rather than a separate allocation of that size for each connection. The Cisco Small Business switch supports 4094 active VLANs and 1000 ACL entries for segmentation and traffic policy. STP/RSTP/MSTP provide loop control, while LACP supports negotiated link aggregation. Three fans cool the chassis within its 0°C to 50°C operating range. 476.6W worst-case consumption, including PoE at 110V, provides the maximum published draw to use when sizing the AC feed and UPS allocation.
ORM Systems offers SG350X-24PD-K9-NA new sealed or certified refurbished; refurbished units are inspected and bench-tested, with PoE output verified under load on every powered port, firmware verified, and configuration wiped to factory default. Specify condition and quantities on the PO: ORM's new warranty is up to 3-year extended, certified refurbished up to 1 year, with 30-day returns on both conditions; terms apply. Cisco's separate limited lifetime hardware warranty remains subject to entitlement, and Cisco service ends July 31, 2027. Enterprise and volume orders can use PO acceptance, Net-30 for government, and RMA with advance replacement, with regional stock and RMA in the UK, EU, US, and MEA.

A site dividing users, voice, and services into separate address spaces can configure 128 IPv4 interfaces and attach routed interfaces to physical ports, link aggregation groups, VLANs, or loopbacks. An IPv6 rollout has a separate ceiling of 106 interfaces. Inventory the required interfaces before specifying the configuration on the PO.
A rollout using centrally prepared configurations can use text-editable configuration files, secure SCP downloads, and Cisco PnP Connect provisioning. DHCP options 66 and 67 support configuration delivery arrangements. Establish the configuration source, provisioning workflow, and administrative credentials before specifying the switches for each site on the purchase order.
A staging team investigating application traffic can mirror eight source ports to one destination port, or mirror eight source VLANs for analysis. RSPAN extends mirroring across a Layer 2 domain, while sFlow exports traffic samples to a collector. Specify the analyzer connection and monitoring configuration before releasing the production purchase order.
More than four multigigabit access connections
Only four access ports reach 2.5Gbps; the other twenty stop at 1Gbps. C1300-24MGP-4X provides eight 2.5Gbps access ports while retaining twenty-four access ports overall.
Maximum PoE on every access port
The shared 375W budget cannot supply 30W simultaneously to all twenty-four access ports, and four ports also support higher 60W loads.
Dynamic routing protocol adjacency
Routing supports manually configured IPv4 and IPv6 paths, not dynamic route exchange. A design requiring routing adjacencies needs a different switching family.

SG350X-24PD-K9-NA identifies a 350X stackable managed switch: twenty Gigabit PoE+ ports, four 2.5G PoE+ ports, and four 10G uplinks. SG350X names the family; 24PD identifies this mixed-speed powered model. K9 remains part of the order code. NA selects the United States, Canada, Mexico, Colombia, Chile, and other LATAM markets.
The Cisco 350X supports management through HTTP/HTTPS, full or menu CLI over console, SSH or Telnet, SNMP, Smart Network Application, FindIT Network Manager with embedded FindIT Network Probe, and Active Advisor. SNMP versions 1, 2c, and 3 are supported; FindIT Network Discovery Utility adds browser-based discovery and inventory.
SG350X-24PD-K9-NA reached end of sale on July 30, 2022, and its last date of support is July 31, 2027. CBS350-24MGP-4X-NA was its immediate replacement but is also discontinued. The current forward replacement is C1300-24MGP-4X; a reseller purchase does not restart the original switch's Cisco support window.
SG350X-24PD-K9-NA is available from ORM Systems new sealed or certified refurbished. New units have up to 3-year extended ORM warranty; certified refurbished units have up to 1 year. Both conditions have 30-day returns, terms apply. Cisco's separate limited lifetime hardware warranty depends on entitlement, and Cisco service ends July 31, 2027.
SG350X-24PD-K9-NA provides a shared 375W PoE budget across twenty-four powered access ports. Four ports support 60W PoE, and the other ports support 30W PoE+. Port ceilings do not add available power: combined endpoint demand must remain within the shared budget. Specify endpoint draw and port assignments rather than assuming maximum output everywhere simultaneously.
SG350X-24PD-K9-NA has four fixed 10G uplinks: two dedicated SFP+ cages and two copper/SFP+ combo connections. Each combo connection activates only one copper or fiber interface at a time. SFP-10G-SR= supports multimode fiber, and SFP-10G-LR= supports single-mode fiber. Optics must be specified separately; the cages are not removable uplink-card bays.
Four Cisco 350X switches form one hardware stack with a single management IP address. The stack can mix SG350X, SG350XG, and SX350X models and use ring or chain connections. Reserve 10G interfaces for interconnects and select supported cabling, such as SFP-H10GB-CU1M= for 1 m or SFP-H10GB-CU3M= for 3 m copper connections.
SG350X-24PD-K9-NA supports static IPv4 and IPv6 routing, with 990 IPv4 static routes and 245 IPv6 static routes. Maximum interface counts are 128 for IPv4 and 106 for IPv6. Routed interfaces can use physical ports, link aggregation groups, VLANs, or loopbacks. This is static routed access rather than dynamic routing protocol adjacency.
SG350X-24PD-K9-NA is a rack-mount 1U switch with an included mounting kit. The chassis measures 440 mm wide, 44 mm high, and 257 mm deep, and weighs 3.99 kg. Cabinet planning should allow for power connections, network cables, and airflow rather than using metal chassis depth as the complete installation clearance.
SG350X-24PD-K9-NA provides 375W of shared PoE power, where SG350X-24P-K9-NA provides 195W. This difference affects combined powered-endpoint demand rather than increasing individual port ceilings. Both models are discontinued; the former addresses legacy spares requiring more aggregate PoE headroom, while the latter matches lower-power installed configurations that remain within its smaller shared allocation.
SG350X-48P-K9-NA has forty-eight access ports, compared with twenty-four on SG350X-24PD-K9-NA. Both models are discontinued, making this a legacy density comparison rather than a current-generation upgrade recommendation. The forty-eight-port model matches higher-density installed configurations; the twenty-four-port model matches existing closets requiring twenty-four access connections rather than a larger access-port count.
C1300-24MGP-4X provides eight 2.5G access ports where SG350X-24PD-K9-NA has four; both have twenty-four access ports overall. SG350X-24PD-K9-NA is discontinued, while C1300-24MGP-4X is the current migration model after the also-discontinued CBS350-24MGP-4X-NA. Current refresh purchases needing more multigigabit connections suit the Catalyst 1300; replacement stock for an existing 350X installation matches the older model.
SG350X-24PD-K9-NA offers 140 Gbps switching capacity and 104.16 Mpps forwarding for 64-byte packets. The MAC table holds 16000 entries, and 3 MB of packet buffering is shared across the switch's ports. System memory is 512 MB DRAM with 256 MB flash, which serve different purposes from packet buffering.
The Cisco 350X supports 1000 ACL entries and 4094 active VLANs on SG350X models, alongside DHCP snooping, IP Source Guard, and Dynamic ARP Inspection. RADIUS and TACACS+ support administrative authentication, while STP/RSTP/MSTP provide loop control. Specify the required access policy and management authentication method before staging the switch configuration.
