CBS350-48P-4G-NA is a managed Layer 2+ 48-port Gigabit PoE+ access switch with four fixed 1G SFP uplinks in a 1U rack-mount chassis. The Cisco Business 350 Series serves small office networks connecting employee computers, IP phones, wireless access points, and cameras; supported powered endpoints receive data and power through their copper connections. Private VLANs and protected ports separate endpoint traffic where business and guest devices share the access edge. The discontinued CBS350-48FP-4G-NA sibling provides a 740W PoE budget for larger allocated endpoint loads. An internal AC supply powers this model without a separate external adapter, and redundant power is not an option. Hardware stacking is not supported, so an additional unit remains a separate switch rather than joining a shared hardware stack.
CBS350-48P-4G-NA price for new stock is $1,571.85, a 50% saving from the Cisco list price of $3,143.70. CBS350-48P-4G-NA refurb price is $643.64. CBS350-48P-4G-NA is in stock and available for next-day dispatch. (terms applied)

104 Gbps switching capacity provides nonblocking switching across the built-in interfaces, while 77.38 Mpps forwarding handles 64-byte packets at the rated packet-processing limit. 370W of shared PoE output requires allocating endpoint demand rather than treating each powered port as an independent maximum-power source. Static IPv4 routing, RIP v2, and PBR provide local IP forwarding and next-hop selection, with 990 static routes available for fixed routing entries. CBS350-48P-4G-NA pairs 512 MB of DRAM with 256 MB of flash for management and image storage. A 3 MB packet buffer is shared dynamically across the ports rather than reserved per interface. STP/RSTP/MSTP addresses loop control, and LACP groups links where an aggregate connection is required. Web configuration, CLI access, and SNMP give Cisco Business administrators local and remote management choices. 451.95W worst-case consumption with PoE at 110V AC informs circuit and UPS sizing. The uplink ports do not support 10G operation.
Specify CBS350-48P-4G-NA new sealed or certified refurbished, including quantity and accessories on the PO. Refurbished units are inspected and bench-tested, with every port linking at rated speed, PoE output verified under load on every powered port, firmware verified, and configurations wiped to factory default. ORM warranties are up to 3-year extended for new and up to 1 year for certified refurbished; returns are 30 days on every condition, terms apply, and Cisco's limited lifetime coverage ends October 31, 2029. ORM Systems accepts POs for enterprise and volume orders, offers Net-30 for government, and provides RMA with advance replacement through UK, EU, US, and MEA regional stock/RMA.

When a maintenance program still carries SG350-52P-K9-NA or SF350-48P-K9-NA, this switch follows their historical migration path. Both legacy models are discontinued, not current alternatives. Before issuing the PO, reconcile the installed configuration, endpoint power demand, and fiber termination against the proposed replacement order and its remaining support window.
When an office needs local communication between separate IP subnets, the switch supports 128 IP interfaces on physical ports, link aggregations, VLAN interfaces, or loopbacks. Define how those interfaces will be allocated and where traffic leaves for the upstream router, then attach the intended IP configuration to the PO.
When multiple offices need matching switch configurations, text-editable configuration files provide a repeatable staging input. Cisco Network Plug and Play handles provisioning, while the embedded Cisco Business Dashboard probe removes the need for a separate probe appliance. Specify the staging configuration and management connection requirements before the PO.
10G uplinks to distribution
CBS350-48P-4G-NA has fixed 1G uplinks. C1300-48P-4X provides four 10G SFP+ uplinks with 48 Gigabit access ports for replacement orders requiring a faster upstream connection.
Hardware stack extension
CBS350-48P-4G-NA cannot join a hardware stack. Centralized Dashboard management does not supply a shared data plane, so this model cannot fulfill a hardware-stack membership requirement.

CBS350-48P-4G-NA identifies a Cisco Business 350 managed switch: CBS350 specifies the series, 48 identifies the copper access port count, P denotes PoE+ ports, 4G identifies four Gigabit SFP uplinks, and NA selects the USA, Canada, Mexico, Colombia, Chile, and remaining Latin America regional ordering variant.
CBS350-48P-4G-NA supports browser management over HTTP/HTTPS, CLI access over SSH or Telnet and the RJ-45 console, Cisco Business Dashboard, Cisco Business mobile app, and SNMP. An embedded Dashboard probe runs on the switch; full and menu-based CLI views are available. Select administrative access settings before staging.
No separate switch license or subscription is required for Cisco Business 350 switches; switch features are included with the hardware purchase. There are no switch feature tiers to select or minimum switch subscription terms to add. Certified refurbished hardware does not create a separate switch software subscription requirement.
370W is the shared PoE budget of CBS350-48P-4G-NA across 48 PoE+ access ports. The switch supports 802.3af PoE and 802.3at PoE+, so powered devices must fit both the supported PoE class and total allocation. Port count alone does not mean every endpoint can draw its maximum simultaneously.
CBS350-48P-4G-NA supports 1G SFP transceivers including GLC-SX-MMD for multimode fiber and GLC-LH-SMD for single-mode fiber. The built-in SFP connections are not 10G SFP+ ports. Match the fiber and remote interface, then put the chosen GLC-SX-MMD or GLC-LH-SMD PID on the PO separately from the switch.
No, CBS350-48P-4G-NA does not support hardware stacking. Centralized Cisco Business Dashboard management does not turn this 1G uplink model into a single hardware stack with shared data and control planes. Buyers extending an existing stack must not order this model as a stack member or allocate its SFP connections to stacking.
Static IPv4 routing, RIP v2, and Policy-Based Routing (PBR) are available on Cisco Business 350 switches. The static route limit is 990, and routed interfaces can use physical ports, link aggregations, VLAN interfaces, or loopbacks. IPv6 routing is also supported; define local routes and the upstream handoff before ordering.
Yes, CBS350-48P-4G-NA is discontinued, with end of sale on October 29, 2024 and last support on October 31, 2029. Software maintenance and vulnerability/security support ended October 29, 2025. C1300-48P-4G is the current migration replacement; remaining CBS350 inventory does not restart the maintenance or support milestones.
CBS350-48P-4G-NA replaces the discontinued SG350-52P-K9-NA and SF350-48P-K9-NA. SG350-52P-K9-NA reached end of sale on October 30, 2021; SF350-48P-K9-NA followed on January 29, 2023. The replacement is also discontinued, with C1300-48P-4G serving as the current migration model, so distinguish historical replacement compatibility from current procurement.
ORM Systems offers CBS350-48P-4G-NA new sealed or certified refurbished, with up to a 3-year extended warranty for new orders and up to 1 year for certified refurbished orders. Returns are 30 days on every condition; terms apply. Cisco's limited lifetime warranty includes next-business-day advance replacement where available, but ends October 31, 2029.
CBS350-48P-4G-NA provides a 370W PoE budget, whereas discontinued CBS350-48FP-4G-NA provides 740W. Both retain 48 Gigabit PoE+ access ports and four 1G SFP uplinks. Both models are discontinued: the first fits lower allocated endpoint loads in existing inventories, while the second fits larger aggregate endpoint power requirements.
CBS350-48P-4G-NA has an internal AC supply; discontinued CBS350-16P-E-2G-NA uses an external AC adapter. These are different power arrangements, not selectable supply options for one chassis. The 48-port model suits dense rack installations with integrated power, while the 16-port model suits smaller endpoint counts accepting a separate adapter.
C1300-48P-4G is the current migration replacement for discontinued CBS350-48P-4G-NA; both have 48 Gigabit Ethernet access ports and four 1G SFP uplinks. The distinction is product generation, not uplink speed. The CBS350 addresses existing-inventory replacement purchases, whereas the Catalyst 1300 model is the migration choice for replacement procurement.
