CBS350-24P-4G is a fanless Layer 2+ managed access switch with 24 Gigabit PoE+ RJ-45 ports and four fixed 1G SFP uplinks for small-office wiring closets and branch racks. The Cisco Business 350 Series Switches are SMB platforms for local access switching, voice, wireless, surveillance, and guest segmentation, with administration through Cisco Business Dashboard, the Cisco Business mobile app, web UI, Textview CLI, SNMP, SSH, and Telnet. This 24-port Gigabit PoE+ access switch fits a standard 1U rack footprint and uses an internal universal AC power supply. CBS350-24FP-4G keeps the same port and 1G uplink layout but raises the PoE budget to 370W for denser powered endpoint loads.
CBS350-24P-4G price for new stock is $1,701.00, a 22.2% saving from the Cisco list price of $2,187.00. CBS350-24P-4G refurb price is $766.68. CBS350-24P-4G is in stock and available for next-day dispatch. (terms applied)

56 Gbps switching capacity and 41.66 Mpps forwarding support wire-speed switching across the access ports and fixed SFP uplinks. 195W PoE budget is shared across 24 PoE+ ports, so endpoint draw has to be sized against the total budget rather than the per-port maximum alone. Static IPv4 routing supports up to 990 routes, with RIP v2, IPv6 routing, Layer 3 interfaces, CIDR, and PBR available for routed SMB edge designs. CBS350-24P-4G also supports STP, RSTP, MSTP, LACP, 4094 VLANs, 16000 MAC addresses, 512 MB DRAM, 256 MB flash, and a 1.5 MB packet buffer. Hardware stacking is not supported on this model, so stack-based expansion belongs with stackable variants rather than this fixed-uplink Gigabit model.
CBS350-24P-4G is available as new sealed stock or certified refurbished stock. Refurbished units are inspected and bench-tested for power-on and POST, every port linking at rated speed, PoE output under load on every powered port, optics bay recognition, PSU status, firmware verification, and configuration wipe to factory default. Add the regional hardware PID, required SFP modules, and endpoint power plan to the purchase order. New hardware can carry up to a 3-year extended warranty, certified refurbished can carry up to 1 year, and every condition has 30-day returns with terms; PO is accepted, Net-30 is available for government, RMA with advance replacement is supported, and stock/RMA coverage spans UK, EU, US, and MEA.

Use the platform where 24 powered Gigabit endpoints fit within a shared 195W supply envelope rather than a full 30W draw per port. Add endpoint class totals, reserve uplink optics such as GLC-SX-MMD or GLC-TE, and size the PO before assigning all 24 ports.
Standardize small-site closets on a 445 mm rack-width platform when locations need local administration through Cisco Business Dashboard, the mobile app, web UI, Textview CLI, or SNMP. Use the country suffix, such as -NA for United States orders, and confirm power cords before release.
Refresh projects replacing SF350-24P-K9-NA or SG350-28P-K9-NA can keep a 24-port PoE access role while moving from older Fast Ethernet or SG350 hardware into Gigabit access ports. Map patch panels, confirm four 1G fiber uplinks, and record lifecycle timing on the PO.
10G uplinks to distribution
CBS350-24P-4G provides four fixed 1G SFP uplinks. C1300-24P-4X is the named 24-port PoE migration model with 4x10G SFP+.
Full PoE on all ports
The 195W budget is below 24 ports at 30W each. C1300-24FP-4G is the named full PoE migration model with 4x1G SFP.
Hardware stacking
CBS350-24P-4G is not one of the models listed for hardware stacking. Select a stackable model only after matching the required port and uplink format.

CBS350-24P-4G identifies a Cisco Business 350 managed switch with 24 10/100/1000 PoE+ ports, a 195W PoE budget, and four Gigabit SFP uplinks. CBS350 is the series family, 24P is the 24-port PoE configuration, and 4G is the Gigabit SFP uplink block.
CBS350-24P-4G is managed through Cisco Business Dashboard, Cisco Business mobile app, a web UI over HTTP or HTTPS, Textview CLI, SNMP, and remote access with SSH or Telnet. It also supports Cisco Network Plug and Play for provisioning, so the management plan can be local, command-line, or dashboard based.
CBS350-24P-4G is end of sale: last order date was 29 October 2024, last ship date was 27 January 2025, and last date of support is 31 October 2029. Cisco named C1300-24P-4G as the migration product for the regional variants of this switch.
CBS350-24P-4G is available from ORM Systems in New sealed and Certified refurbished condition. Cisco's limited lifetime warranty remains bounded by 31 October 2029 last support, while ORM offers up to 3-year extended warranty on new units, up to 1 year on refurbished units, and 30-day returns with terms.
CBS350-24P-4G does not use a separate software-license tier. The switch is sold as a regional hardware PID, such as CBS350-24P-4G-NA for the United States, so quotes should focus on the switch, required SFP modules, power cords, and spares.
CBS350-24P-4G has 24 PoE+ Gigabit RJ-45 ports and a 195W total PoE budget. The budget is shared across the powered ports, so 24 endpoints at the 30W PoE+ maximum would exceed the available budget and need a different power plan.
CBS350-24P-4G has four fixed 1G SFP uplinks. Supported 1G SFP choices include MGBSX1, MGBLX1, MGBLH1, MGBT1, GLC-SX-MMD, GLC-LH-SMD, GLC-BX-U, GLC-BX-D, and GLC-TE; 10G SFP+ uplinks belong to other models such as CBS350-24P-4X.
CBS350-24P-4G does not support hardware stacking. The stackable list starts with models such as CBS350-24T-4X, CBS350-24P-4X, and CBS350-24FP-4X, and supported stacks can contain up to 4 units using 10G fiber interfaces. Treat this model as a standalone managed switch.
CBS350-24P-4G supports static IPv4 routing up to 990 routes, RIP v2, IPv6 routing, Layer 3 interfaces, CIDR, and PBR. The routing set fits Layer 2+ use, with inter-VLAN routing handled on the switch and larger dynamic routing roles kept off the access layer.
CBS350-24P-4G is a fanless 1U rack-mount switch with a 445 mm width, 299 mm depth, 44 mm height, and 3.53 kg weight. The internal universal AC power input is 100-240V AC at 50-60 Hz, with no separately orderable power-supply spare PID listed.
CBS350-24P-4G-NA replaced SF350-24P-K9-NA for 24-port Fast Ethernet PoE refreshes and SG350-28P-K9-NA for 28-port Gigabit PoE refreshes. The older products reached end of sale on 29 January 2023 and 30 October 2021 respectively.
CBS350-24FP-4G raises the PoE budget to 370W, while CBS350-24P-4G provides 195W with the same 24 Gigabit PoE+ ports and four 1G SFP uplinks. Choose CBS350-24P-4G for lower aggregate endpoint draw, and choose CBS350-24FP-4G when the powered-port budget is the gating item.
CBS350-24P-4X carries four 10G SFP+ uplinks, while CBS350-24P-4G carries four 1G SFP uplinks with the same 24-port PoE+ access role. Choose CBS350-24P-4G for Gigabit fiber uplinks, and choose CBS350-24P-4X when the distribution handoff requires 10G SFP+.
C1300-24P-4G is the named migration product, while CBS350-24P-4G is end of sale with last support on 31 October 2029. The migration description keeps the 24-port GE PoE and 4x1G SFP role, so CBS350 fits like-for-like sparing and C1300 fits refresh quoting.
