SG350X-48P combines 48 Gigabit PoE+ access ports with four fixed 10G uplinks in a managed, rack-mount 1U chassis. Two uplinks are dedicated SFP+ connections; the other two provide a choice between 10GBASE-T copper and SFP+ fiber, with only one interface active on each shared connection. This architecture accommodates copper or fiber distribution links without a removable uplink card. The Cisco 350X Series Stackable Managed Switches serve small and midsize business networks requiring powered endpoint connections and hardware stacking. Static routing places this model in the Layer 2+ category rather than a dynamic-routing access tier. The discontinued SG350X-48MP sibling increases the available endpoint power budget to 740W while retaining the same access-port density and uplink arrangement.

176 Gbps switching capacity provides nonblocking forwarding across the access and uplink interfaces, while 130.94 Mpps is the forwarding rate for 64-byte packets. 382W of shared PoE power requires endpoint demand to be allocated across the powered connections rather than treating every port's maximum output as simultaneously available. Static IPv4 routing supports 990 routes and 128 IP interfaces; IPv6 static routing supports 245 routes and 106 interfaces. Dynamic routing is not supported. SG350X-48P combines 512 MB of DRAM, 256 MB of flash and a 3 MB packet buffer shared across its ports. Browser-based configuration offers simple and advanced modes, while the full and menu CLI support scripted administration. Dual firmware images provide a separate image for upgrade recovery. 492.3W maximum consumption with PoE at 110V is the figure to use when allocating AC circuit or UPS capacity, rather than sizing electrical input from the endpoint power budget alone.
SG350X-48P is offered new sealed or certified refurbished; specify the condition, regional ordering variant and required link components on the purchase order. Certified refurbished units are inspected and bench-tested, with power-on and POST, rated-speed port links, clean boot and PoE output verified under load on every powered port; firmware is verified and configurations are wiped to factory default. New units carry up to a 3-year extended warranty, certified refurbished units carry up to 1 year, and every condition includes 30-day returns; terms apply. For enterprise and volume orders, ORM Systems accepts POs, provides Net-30 for government and RMA with advance replacement, with regional stock and RMA coverage across the UK, EU, US and MEA.

When an endpoint schedule includes devices requiring more than standard PoE+ output, eight selected access ports support 60W PoE, while the remaining powered ports support 30W. Assign those devices to the appropriate connections and confirm their power compatibility before specifying the port map and endpoint quantities on the purchase order.
When extending an installed 350X stack, choose ring or chain topology before allocating external links. Stack interconnects can use link aggregation, with master and backup control for the assembled system. Record the interconnect port assignments, remaining external connections and intended topology in the order's configuration requirements.
When multiple sites need a common staged configuration, DHCP options 66 and 67 support provisioning information, and configuration files can be edited and transferred between switches. Secure Copy provides a protected file-transfer path. Specify the configuration template, addressing requirements and provisioning method before releasing the hardware purchase order.
Dynamic routing at the access edge
SG350X-48P supports static IPv4 and IPv6 routing rather than dynamic route exchange. Networks requiring automatic route learning need a switch that supports their required dynamic routing protocols.
Manufacturer support beyond October 2026
Cisco service for SG350X-48P ends October 31, 2026. C1300-48P-4X is the current migration destination through the discontinued CBS350-48P-4X-NA, retaining 48 Gigabit access ports and four 10G uplinks.
Maximum PoE output on every port
The 382W budget is shared across the powered connections and cannot provide every port's maximum output simultaneously. Specify equipment with sufficient aggregate endpoint power for the intended device schedule.

SG350X-48P identifies a 350X Gigabit stackable managed switch: SG350X is the family identifier, 48 identifies the access-port count, and P identifies the powered-port model. The configuration includes PoE+ access connections and fixed 10G uplinks. For United States orders, the complete regional ordering name is SG350X-48P-K9-NA.
SG350X-48P supports HTTP/HTTPS web management, full or menu CLI through the RJ-45 console, SSH or Telnet, and SNMP versions 1, 2 and 3. Network-level integrations include Smart Network Application, Cisco FindIT Network Manager with an embedded FindIT Network Probe, and Active Advisor. Specify the required administrative access method during configuration staging.
SG350X-48P provides a shared 382W PoE budget across 48 powered access ports. Eight selected ports support 60W PoE, and the remaining powered ports support 30W. Those individual limits do not represent simultaneous output across every connection; the combined allocation must remain within the switch's total available endpoint power.
SG350X-48P provides four fixed 10G uplinks: two dedicated SFP+ ports and two shared 10GBASE-T/SFP+ combo ports. Supported fiber transceivers include SFP-10G-SR= for multimode links and SFP-10G-LR= for single-mode links. Each combo connection activates either its copper interface or its SFP+ interface, not both at the same time.
Cisco 350X hardware stacking supports four members managed as one system, including mixed SG350X, SG350XG and SX350X models. Ring and chain arrangements use 10G copper or fiber interfaces. Supported direct-attach cable choices include SFP-H10GB-CU1M=, SFP-H10GB-CU3M= and SFP-H10GB-CU5M=; allocate the interconnect ports before counting available external uplinks.
Yes, SG350X-48P supports static inter-VLAN routing, including 990 IPv4 static routes and 128 IP interfaces. IPv6 static routing supports 245 routes and 106 interfaces. Routing interfaces can be configured on physical ports, link aggregation groups, VLAN interfaces or loopback interfaces. The routing capability does not include dynamic route exchange.
Yes, SG350X-48P reached end of sale on October 30, 2021, and Cisco's last date of support is October 31, 2026. Software maintenance ended October 30, 2022. The original replacement, CBS350-48P-4X-NA, is also discontinued; the current migration destination reached through that replacement is C1300-48P-4X.
SG350X-48P replaces the discontinued SF550X-48P-K9-AR, SF550X-48P-K9-BR, SF550X-48P-K9-EU, SF550X-48P-K9-NA, SF550X-48P-K9-UK and SF550X-48P-K9-CN regional models. Those predecessors provide 10/100 access connections rather than Gigabit access. For procurement following the migration chain beyond both discontinued generations, the current destination is C1300-48P-4X; retaining SG350X hardware is an existing-generation purchasing decision.
SG350X-48P is offered new sealed or certified refurbished by ORM Systems: new units carry up to a 3-year extended warranty; refurbished units carry up to 1 year. Every condition has 30-day returns; terms apply. Cisco's separate limited lifetime hardware warranty remains subject to entitlement, and Cisco service ends October 31, 2026.
SG350X-48MP provides a 740W PoE budget, compared with 382W on SG350X-48P; both models are discontinued. The larger allocation changes aggregate endpoint power availability rather than access-port density. SG350X-48P suits existing installations with lower combined endpoint demand, while SG350X-48MP suits existing-generation installations requiring the higher available power budget.
SG350X-48P provides 48 Gigabit access ports, while SG350X-24P provides 24; both models are discontinued. Match that density to the required wired endpoint count and spare connections when maintaining an existing installation. SG350X-24P suits lower-density existing networks, while SG350X-48P suits installations requiring the larger access-port count within this generation.
C1300-48P-4X provides four 10G SFP+ uplinks, while SG350X-48P combines two dedicated SFP+ uplinks with two shared copper/SFP+ uplinks. SG350X-48P is discontinued and suits retention of existing-generation hardware with copper uplink requirements. C1300-48P-4X is the current migration destination for buyers specifying the successor with an all-SFP+ uplink arrangement.
