CBS350-48FP-4G is a 48-port Gigabit PoE+ managed switch with four fixed 1G SFP uplinks and a full-width 1U rack chassis. Dedicated fiber connections leave the copper access ports available for endpoints rather than sharing combo connections. The Cisco Business 350 Series serves small-business networks combining wired users, IP phones, wireless access points, and surveillance cameras. Layer 2+ functionality provides local routed connectivity alongside Ethernet switching. Voice VLAN handling separates phone traffic and applies QoS, while guest VLAN and protected-port controls provide additional traffic separation. Compared with the discontinued CBS350-48P-4G, which allocates 370W to PoE, this configuration provides a larger shared endpoint-power allowance. The fixed uplink architecture keeps this model within the Gigabit uplink class rather than providing a removable uplink-card expansion path.
CBS350-48FP-4G price for new stock is $1,711.50, a 22.2% saving from the Cisco list price of $2,200.50. CBS350-48FP-4G refurb price is $1,312.50. CBS350-48FP-4G is in stock and available for next-day dispatch. (terms applied)

104 Gbps switching capacity provides aggregate bandwidth across the built-in interfaces. 77.38 Mpps forwarding capacity sets the packet-processing ceiling for 64-byte packets when sizing short-frame traffic. 740W of shared PoE capacity requires endpoint allocations to be considered together rather than assuming every powered port can consume its maximum simultaneously. Static routing, RIP v2, and PBR provide local routing control, with 990 IPv4 static routes and 128 IP interfaces setting the configuration bounds. CBS350-48FP-4G pairs 512 MB of DRAM with 256 MB of flash for operation and image storage; its 3 MB packet buffer is dynamically shared across ports. Browser-based HTTP/HTTPS administration, Textview CLI over console, SSH or Telnet, SNMP, Cisco Business Dashboard, and the mobile app provide management paths. STP, RSTP, MSTP, and LACP handle loop protection and link aggregation. Hardware stacking is not supported on this configuration, so multiple units remain individual switches rather than members of one hardware stack.
ORM Systems offers CBS350-48FP-4G new sealed with up to a 3-year extended ORM warranty or certified refurbished with up to 1 year; both conditions have 30-day returns, terms apply. Certified refurbished units are inspected and bench-tested, with PoE output verified under load on every powered port; Cisco's separate platform warranty is limited lifetime, with Cisco service ending October 31, 2029. Specify condition, required optics, destination, and quantity on the purchase order. Enterprise and volume orders support PO acceptance, Net-30 for government, and RMA with advance replacement through regional stock and RMA coverage in the UK, EU, US, and MEA.

An installed SG350-52MP-K9-NA or SF350-48MP-K9-NA can trigger an installed-base matching purchase. Those discontinued models ended sale on October 30, 2021 and July 30, 2022, respectively, and CBS350-48FP-4G is their replacement configuration. Before the PO, verify existing uplink connections, endpoint requirements, and the regional order variant rather than treating the older model names as interchangeable configurations.
A branch rollout needs mounting hardware and a destination-matched power cord, not just a switch chassis. Both accompany new Cisco Business 350 Series units, while Category 5e or better cabling supports copper connections. Confirm the mounting kit, destination power cord, and required patch-cable quantities before approving the purchase order.
For a staging bench that validates configuration changes before shipment, the Cisco Business 350 Series supports dual firmware images and a USB Type-A slot for image and file management. Keep the approved image and configuration with the deployment record, and specify firmware verification and a factory-default configuration for certified refurbished units.
10G uplinks to distribution
CBS350-48FP-4G has four 1G SFP uplinks, not 10G SFP+ uplinks. C1300-48FP-4X provides four 10G SFP+ uplinks while retaining 48 Gigabit access ports.
Hardware stacking across multiple switches
CBS350-48FP-4G does not support hardware stacking. Central management does not combine separate units into one hardware switch, so this model cannot serve as a hardware-stack member.
Fanless operation in occupied spaces
CBS350-48FP-4G uses one cooling fan and has an acoustic rating of 48.7 dBA at 25°C, so the chassis cannot satisfy a fanless requirement.

Excellent 48-port PoE solution. Fast, stable, and very easy to manage.
CBS350-48FP-4G identifies a Cisco Business 350 managed switch: CBS350 is the series, 48 is the Gigabit access-port count, FP selects the 740W PoE+ configuration, and 4G specifies four Gigabit SFP uplinks. The supplied part number has no separate license-tier suffix or removable uplink-module designation.
The Cisco Business 350 Series is managed through HTTP/HTTPS web access, console or SSH/Telnet CLI, SNMP, Cisco Business Dashboard, and the Cisco Business mobile app. The embedded Dashboard probe removes the need for a separate probe appliance. Cisco Network Plug and Play supports provisioning during device rollouts.
740W is the shared PoE budget of CBS350-48FP-4G across 48 PoE+ access ports. The budget is allocated among connected endpoints rather than reserved independently at maximum power for every port. Size the purchase around the combined power reservations of phones, access points, and cameras, not just the number of connections.
MGBSX1 and MGBLX1 are supported 1G fiber transceivers for the Cisco Business 350 Series. MGBSX1 supports multimode fiber to 500 m, while MGBLX1 supports single-mode fiber to 10 km. Select the transceiver for the installed fiber type and link distance, and include the optic PID on the purchase order.
CBS350-48FP-4G supports static routing, RIP v2, and PBR, with a limit of 990 IPv4 static routes. The configuration also supports 128 IP interfaces on physical ports, LAGs, VLANs, or loopback interfaces. Specify the required route and interface counts before ordering, and keep both within the switch's configuration limits.
No, CBS350-48FP-4G does not support hardware stacking. Central management through Cisco Business Dashboard does not turn separate units into a single hardware switch. The series' stacking capability is restricted to selected 10G-uplink, multigigabit, and 10G models. Treat this configuration as an individual switch when planning quantities and connections.
CBS350-48FP-4G uses an internal universal AC power supply accepting 100-240V AC at 50-60 Hz. The chassis does not provide a redundant PSU option. Worst-case consumption with PoE is 886.42W at 110V and 859.5W at 220V, so electrical and UPS sizing must include endpoint power, not just switching electronics.
Yes, CBS350-48FP-4G is a 1U rack-mount switch measuring 445 mm wide, 350 mm deep, and 44 mm high. The unit weighs 5.82 kg, and new units include mounting hardware. Allow for the chassis depth and confirm the mounting kit is included with the selected order condition before issuing the PO.
No license or software subscription is required for CBS350-48FP-4G; the switch's features accompany the hardware purchase. There is no minimum subscription term or separate network-license tier to select for this model. An ORM order therefore does not need an added switch software-subscription line item.
Yes, CBS350-48FP-4G ended sale on October 29, 2024. Software maintenance and vulnerability/security fixes ended on October 29, 2025. Cisco's last support date is October 31, 2029, so remaining hardware support does not imply continuing software fixes. C1300-48FP-4G is the current replacement rather than another discontinued CBS350 configuration.
CBS350-48FP-4G replaces SG350-52MP-K9-AU, SG350-52MP-K9-EU, SG350-52MP-K9-IN, SG350-52MP-K9-NA, SG350-52MP-K9-UK, SF350-48MP-K9-AU, SF350-48MP-K9-BR, SF350-48MP-K9-IN, SF350-48MP-K9-EU, SF350-48MP-K9-NA, and SF350-48MP-K9-UK. Most ended sale October 30, 2021; SF350-48MP-K9-EU, SF350-48MP-K9-NA, and SF350-48MP-K9-UK ended sale July 30, 2022. Confirm the regional order variant and power cord when matching installed equipment.
CBS350-48FP-4G provides a 740W PoE budget, while CBS350-48P-4G provides 370W. Both configurations have 48 PoE+ access ports and ended sale on October 29, 2024. The larger allocation addresses higher combined endpoint reservations; the smaller allocation suits installed-base requirements whose total reserved endpoint power remains within 370W.
CBS350-48FP-4G has four 1G SFP uplinks, while CBS350-48FP-4X has four 10G SFP+ uplinks. Both models ended sale on October 29, 2024. The 1G configuration suits existing Gigabit uplink connections; buyers specifying a current 10G-uplink replacement should use C1300-48FP-4X rather than treating CBS350-48FP-4X as current production.
CBS350-48FP-4G ended sale on October 29, 2024, while C1300-48FP-4G is its current replacement. Both have 48 Gigabit access ports and four 1G SFP uplinks. The older model suits installed-base matching from discontinued inventory; the successor suits buyers specifying the current replacement instead of another legacy purchase.
ORM Systems offers CBS350-48FP-4G new sealed with up to a 3-year extended ORM warranty or certified refurbished with up to 1 year. Both conditions have 30-day returns, terms apply. Cisco's limited lifetime warranty includes next-business-day advance replacement where available; Cisco service ends October 31, 2029.
