SG350X-48PV-K9 combines eight 100M/1G/2.5G/5G access ports with 40 Gigabit access ports, providing PoE+ throughout the access bank. The managed Layer 2+ switch has four fixed 10G uplinks: two dedicated SFP+ connections and two copper/SFP+ combo connections. Its 1U rack-mount chassis belongs to the Cisco 350X Series Stackable Managed Switches, serving small-business networks with powered phones, wireless access points and cameras. The discontinued SG350X-48P-K9-NA has a smaller 382W PoE allocation. Gigabit endpoints can occupy the standard-speed ports while faster access points use the multigigabit connections. The fixed uplink architecture requires no removable network card, but the eight faster access connections should not be mistaken for an entirely multigigabit downlink bank.

240 Gbps switching capacity supports the mixed-speed port configuration, while 178.56 Mpps forwarding handles minimum-size packets. 740W of shared PoE power must cover the aggregate endpoint demand rather than every port’s individual maximum. 990 static IPv4 routes support local routed connections, with 128 IP interfaces available; IPv6 static routing supports 245 routes and 106 interfaces. Dynamic routing is not part of this feature set. SG350X-48PV-K9 has 512 MB of memory and 256 MB of flash, separating working memory from software storage. A shared 6 MB packet buffer handles traffic across the ports, and the MAC address table accommodates 16000 entries. STP, RSTP, MSTP and LACP provide loop-control and link-aggregation options, while DHCP snooping and Dynamic ARP Inspection support access security. Browser configuration and a scriptable CLI provide interactive and repeatable administration. 916W worst-case consumption with PoE is the maximum figure to carry into electrical capacity planning.
ORM Systems supplies SG350X-48PV-K9 in new sealed and certified refurbished condition. Certified refurbished units are inspected and bench-tested, including power-on and POST, rated-speed port links, clean boot, PoE output under load on every powered port, firmware verification and configuration wiped to factory default. Specify condition, regional ordering suffix, required optics and quantity on the PO; new units carry up to a 3-year extended warranty, certified refurbished units up to 1 year, and every condition has 30-day returns, terms apply. POs are accepted, government buyers have Net-30, and enterprise or volume orders can use UK, EU, US and MEA regional stock and RMA with advance replacement.

When branch switches will receive centrally prepared configurations, Cisco Network Plug and Play provides a provisioning path, while CLI privilege levels 1, 7 and 15 separate administrative access. Establish the provisioning workflow and administrator roles during staging, then specify the required console connectivity before the PO.
When a replacement must pass a software acceptance process before installation, dual software images and front-panel USB file transfer support preparation and recovery procedures. Image signing and Secure Boot are available on this model. Define the accepted image, configuration backup and clean-boot checks before ordering the staging units.
When a common hardware configuration is being ordered for several regions, SG350X-48PV-K9-NA is the North American form, while SG350X-48PV-K9-UK and SG350X-48PV-K9-EU identify other regional orders. The unsuffixed catalog identifier does not select a region. Specify the destination and complete regional PID on each purchase order.
More than eight multigigabit endpoints
Only eight access ports support 2.5G or 5G; the remaining 40 access ports stop at Gigabit Ethernet. A larger multigigabit endpoint population exceeds this configuration.
Dynamic routing between access VLANs
Routing is limited to static IPv4 and IPv6 routes. A deployment requiring a dynamic routing control plane needs a different switching configuration.
Cisco support beyond July 2027
Cisco support ends July 31, 2027. The discontinued replacement, CBS350-48NGP-4X-NA, has no current successor named in its migration path, so this chain does not provide a current alternative.

SG350X-48PV-K9 identifies a 350X stackable managed switch with 48 powered access ports. The 48 denotes access-port density, while PV identifies the mixed Gigabit and 5G PoE configuration. K9 remains part of the ordering identifier. A complete regional order adds a suffix, such as SG350X-48PV-K9-NA for North America.
SG350X-48PV-K9 supports an HTTP/HTTPS web interface, full or menu CLI through console/SSH/Telnet, SNMP, Smart Network Application, FindIT Network Manager with an embedded probe, and Active Advisor. FindIT Network Discovery assists discovery, while Cisco Network Plug and Play supports provisioning. The browser interface includes simple and advanced modes.
Yes, SG350X-48PV-K9 is discontinued: the North American regional model reached end of sale on July 30, 2022. Software maintenance ended July 30, 2023, and the last date of Cisco support is July 31, 2027. Availability through a reseller does not restart those lifecycle milestones.
ORM Systems offers SG350X-48PV-K9 new sealed or certified refurbished, with up to a 3-year extended warranty for new units and up to 1 year for refurbished units. Every condition has 30-day returns, terms apply. Cisco’s separate limited lifetime hardware warranty is bounded by its July 31, 2027 support end date.
SG350X-48PV-K9 provides a shared 740W PoE budget across 48 powered access ports. Eight ports support 60W each, while the other 40 support 30W each. Those individual limits are not simultaneously available across every port; the combined connected load must remain within the switch’s total allocation.
SG350X-48PV-K9 has two dedicated 10G SFP+ uplinks and two 10G copper/SFP+ combo uplinks. Each combo pair uses either copper or fiber, not both simultaneously. Supported fiber options include SFP-10G-SR= for multimode connections and SFP-10G-LR= for single-mode connections; select the required media when specifying the order.
Cisco 350X hardware stacking supports four members managed as one system. Supported hybrid stacks can mix SG350X, SG350XG and SX350X models, using 10G copper or fiber interfaces for interconnection. Ring and chain arrangements are supported. SFP-H10GB-CU1M=, SFP-H10GB-CU3M= and SFP-H10GB-CU5M= provide supported copper cable options.
Yes, Cisco 350X switches provide static IPv4 and IPv6 routing between configured interfaces, including VLAN interfaces. IPv4 capacity reaches 990 static routes and 128 IP interfaces; IPv6 supports 245 static routes and 106 interfaces. This is static routed access rather than a dynamic-routing feature set.
SG350X-48PV-K9 provides a 740W PoE budget, compared with 382W on SG350X-48P-K9-NA. Both models are discontinued. The larger allocation suits a higher aggregate endpoint power requirement, while the smaller allocation suits a lower-power endpoint mix; neither budget removes the need to total the connected loads.
SG350X-48PV-K9 includes eight access ports supporting 2.5G and 5G, whereas SG350X-48MP-K9-NA has Gigabit access ports throughout. Both models are discontinued. The PV configuration suits an existing deployment with faster copper endpoints; the MP configuration suits endpoints whose required access speed remains at Gigabit Ethernet.
SG350X-48PV-K9 has 48 access ports, while SG350X-24PV-K9-NA has 24 access ports. Both discontinued configurations retain eight 5G-capable access connections. The 48-port version suits a larger population of additional Gigabit endpoints; the 24-port version suits a smaller endpoint population without increasing the number of multigigabit connections.
SG350X-48PV-K9 was replaced in North America by CBS350-48NGP-4X-NA, but that replacement is also discontinued and has no current successor in its migration path. CBS350-48NGP-4X-NA reached end of sale on May 30, 2024, with Cisco support ending May 31, 2029. It should not be treated as a current-generation alternative.
