CBS350-48T-4G-NA provides 48 copper Gigabit Ethernet access ports and four fixed 1G SFP uplinks in a managed, non-PoE rack switch. Its Layer 2+ capabilities combine VLAN switching with static routing, RIP v2 and policy-based routing for small-business access networks. The Cisco Business 350 Series connects computers, printers and independently powered network devices rather than supplying endpoint power. Unlike the discontinued CBS350-48P-4G-NA, this model has no PoE output. The full-width 1U chassis accommodates a conventional equipment rack, while dedicated fiber uplinks leave the copper access connections available for endpoints. This 48-port Gigabit managed switch uses fixed interfaces rather than an uplink expansion bay, so a later uplink-speed upgrade requires different hardware.
CBS350-48T-4G-NA price for new stock is $941.85. CBS350-48T-4G-NA refurb price is $539.60. CBS350-48T-4G-NA is in stock and available for next-day dispatch. (terms applied)

104 Gbps switching capacity accommodates simultaneous traffic across the access and uplink interfaces without an oversubscribed switching fabric. 77.38 Mpps forwarding handles 64-byte packets at the published maximum packet rate. Static routing supports 990 IPv4 routes, while RIP v2 provides dynamic route exchange and PBR selects next hops through traffic policies. The switch supports 128 IP interfaces for routed connections. CBS350-48T-4G-NA contains 512 MB of DRAM and 256 MB of flash for its embedded operating software and configuration storage. A dynamically shared 3 MB packet buffer absorbs traffic bursts across the ports. STP, RSTP and MSTP provide loop-control options, and LACP supports aggregated connections. Management includes a browser interface, a scriptable CLI and centralized administration through Cisco Business Dashboard. Hardware stacking is absent on this model; centralized visibility does not turn multiple units into one forwarding system.
ORM Systems offers CBS350-48T-4G-NA new sealed or certified refurbished, with up to a 3-year extended warranty on new units, up to 1 year on certified refurbished units, and 30-day returns on every condition; terms apply. Refurbished units are inspected and bench-tested for power-on and POST, rated-speed port links, clean boot and optics bay recognition, with firmware verified and configurations wiped to factory default. Specify condition, quantities and required optics on the purchase order; eligible Cisco limited lifetime hardware coverage is separate, with service ending October 31, 2029. Enterprise and volume orders support POs, Net-30 for government and RMA with advance replacement, with regional stock/RMA across the UK, EU, US and MEA.

Replacement PID | C1300-48T-4G |
When replacing discontinued SG350-52-K9-NA or SF350-48-K9-NA equipment within an established hardware standard, this model follows both earlier ordering paths. Existing configurations still require migration review rather than an assumption of direct interchangeability. Identify the outgoing PID and prepare the configuration conversion before specifying replacement quantities.
When multiple offices require a common configuration baseline, editable configuration files and SCP transfers support repeatable provisioning. CLI privilege levels 1, 7 and 15 separate operator access. Define the baseline file, credential handling and required administrator privileges before ordering units for a standardized rollout.
When a staging bench needs packet visibility before equipment enters service, port mirroring can send traffic from eight source ports to one analyzer destination. The sFlow agent also exports traffic samples to an external collector. Specify the analyzer connection and collection requirements before adding laboratory units to the PO.
PoE power for connected endpoints
CBS350-48T-4G-NA supplies no endpoint power. C1300-48P-4G provides 48 PoE+ access ports with a shared 370W budget while retaining four Gigabit SFP uplinks.
10G uplinks to upstream equipment
CBS350-48T-4G-NA is limited to Gigabit SFP uplinks. C1300-48T-4X retains 48 Gigabit copper access ports but provides four fixed 10G SFP+ uplinks instead.

CBS350-48T-4G-NA identifies a Cisco Business 350 managed switch: 48 denotes the access-port count, T identifies the non-PoE copper configuration, and 4G denotes four Gigabit SFP uplinks. NA selects the regional version covering the United States, Canada, Mexico, Colombia, Chile and the rest of Latin America.
Cisco Business 350 switches support an HTTP/HTTPS web interface, CLI access through the RJ-45 console or SSH/Telnet, SNMP, Cisco Business Dashboard and the Cisco Business mobile app. The embedded Dashboard probe avoids a separate on-site probe appliance, while the CLI supports scripting and differentiated administrator privileges.
Yes, CBS350-48T-4G-NA reached end of sale on October 29, 2024, and its replacement is C1300-48T-4G. Software maintenance and scheduled vulnerability support ended October 29, 2025. Eligible hardware service continues until October 31, 2029, so remaining hardware support should not be confused with continuing security maintenance.
ORM Systems offers CBS350-48T-4G-NA new sealed or certified refurbished, with up to a 3-year extended warranty for new units and up to 1 year for refurbished units. Returns are 30 days on every condition; terms apply. Eligible Cisco limited lifetime hardware coverage is separate, with Cisco service ending October 31, 2029.
CBS350-48T-4G-NA replaces SG350-52-K9-NA and SF350-48-K9-NA, both discontinued models. SG350-52-K9-NA reached end of sale on October 30, 2021; SF350-48-K9-NA followed on July 30, 2022. The subsequent replacement for CBS350-48T-4G-NA is C1300-48T-4G, making the Business 350 model an intermediate generation in that migration chain.
CBS350-48P-4G-NA supplies PoE+ through 48 access ports with a shared 370W budget, whereas CBS350-48T-4G-NA supplies no endpoint power. Both models are discontinued. The T model fits independently powered equipment; the P model adds endpoint power where its shared budget covers the connected load.
CBS350-48T-4X-NA provides four 10G SFP+ uplinks, whereas CBS350-48T-4G-NA provides four 1G SFP uplinks. Both models are discontinued and retain 48 Gigabit copper access ports. The 4G model fits Gigabit upstream connections; the 4X model accommodates faster upstream links where existing hardware standards require that generation.
C1300-48T-4G consumes 38.8W under worst-case conditions at 110V, compared with 48.27W for CBS350-48T-4G-NA at the same voltage. C1300-48T-4G is the current replacement. The successor suits purchases prioritizing the lower published power requirement; the discontinued Business 350 model serves buyers maintaining an existing equipment standard.
Yes, CBS350-48T-4G-NA supports inter-VLAN routing through static routes, RIP v2 and PBR, with 990 static IPv4 routes and 128 IP interfaces. Routing interfaces can use physical ports, link aggregation groups, VLAN interfaces or loopbacks. These capabilities provide local routing without making this model an advanced dynamic-routing switch.
No, CBS350-48T-4G-NA cannot form a hardware stack. Hardware stacking belongs to selected other Business 350 configurations, not this four-Gigabit-uplink model. Cisco Business Dashboard can provide centralized administration, but connected units remain separate switches rather than members of a single hardware stack with shared forwarding control.
