CBS250-24P-4G is a 24-port Gigabit PoE+ smart managed switch for small-business access closets, with fixed 1G SFP uplinks and a rack-mount 1U chassis. The Layer 2+ Business 250 model provides 10/100/1000 copper access for phones, cameras, wireless access points and workstations while keeping fiber handoff on four dedicated SFP cages. The Cisco Business 250 Series is managed through local web and CLI tools as well as Cisco Business Dashboard and the mobile app, so it fits sites that need static routing and policy controls without a separate license tier. CBS250-24PP-4G carries the same 24 Gigabit PoE+ ports and four 1G SFP uplinks but uses a smaller 100W PoE budget.
CBS250-24P-4G price for new stock is $729.75, a 61.3% saving from the Cisco list price of $1,883.25. CBS250-24P-4G refurb price is $519.75. CBS250-24P-4G is in stock and available for next-day dispatch. (terms applied)

56 Gbps switching capacity and 41.66 Mpps forwarding support wire-speed, nonblocking operation across the Gigabit access and uplink ports. 195W of PoE capacity is shared across 24 powered ports, with 30W maximum to any 10/100/1000 port until the budget is reached. CBS250-24P-4G supports static IPv4 routing up to 32 routes and 16 IP interfaces, IPv6 routing, STP/RSTP/MSTP, LACP, 255 active VLANs and an 8K MAC table. 512 MB DRAM, 256 MB flash and a 1.5 MB shared packet buffer support the embedded smart-switch software. 239.7W worst-case draw guides UPS and circuit sizing when the PoE budget is allocated, and fanless cooling supports quiet open-rack placement. Management options include Cisco Business Dashboard, the Cisco Business mobile app, web UI over HTTP/HTTPS, text-view CLI, SNMP, SSH and Telnet, with firmware upgrades through browser, TFTP or SCP.
Order CBS250-24P-4G new sealed or certified refurbished, with required 1G SFP optics and the regional order suffix on the same PO. Certified refurbished units are inspected and bench-tested; managed units are firmware verified, wiped to factory default, checked for clean boot, PoE output under load and optics bay recognition. New hardware is eligible for up to a 3-year extended warranty, certified refurbished hardware for up to 1 year, and returns are 30 days on every condition; terms apply. ORM Systems accepts POs, offers Net-30 for government buyers, provides RMA with advance replacement, and supports regional stock and RMA coverage across the UK, EU, US and MEA.

An access closet with phones, cameras or wireless APs can use the 24 PoE+ RJ-45 ports and four 1G SFP uplinks in one 1U chassis. Before the PO, total endpoint draw against the shared power budget and list any required 1G optics.
A branch edge that needs copper access and fiber handoff can terminate 24 Gigabit access drops locally while using the four fixed SFP ports toward aggregation. Specify supported 1G transceiver PIDs, fiber type and regional order suffix with the switch so optics and cabling arrive together.
Multi-site refreshes that do not need a full enterprise license can standardize on the smart managed Business 250 feature set, including web UI, CLI, SNMP, Cisco Business Dashboard and mobile app. Check the 31 October 2029 support date when setting spares policy and rollout timing.
10G fiber uplinks
CBS250-24P-4G has four 1G SFP uplinks, not SFP+. Use current C1200-24P-4X for 24 Gigabit PoE+ ports with four 10G SFP+ uplinks.
Full 24-port PoE+ draw
The 195W budget is below 24 × 30W. Use current C1200-24FP-4G for a 24-port Gigabit PoE+ model with a 375W budget.
Dynamic routing protocols
Layer 3 features are static IPv4 routing up to 32 routes and IPv6 routing. Dynamic routing requirements need a different managed access platform.
Stacked access switching
Business 250 has no stack-member limit or stacking kit for this model. Build separate switches with uplinks, or use a platform with hardware stacking.

CBS250-24P-4G identifies a Cisco Business 250 smart switch with 24 10/100/1000 PoE+ ports and four Gigabit SFP uplinks. CBS250 is the switch family, 24P maps to 24 powered Gigabit access ports with a 195W budget, and 4G maps to four 1G SFP uplink cages.
CBS250-24P-4G is managed through Cisco Business Dashboard, the Cisco Business mobile app, a browser web UI over HTTP or HTTPS, CLI access over SSH or Telnet, and SNMP. The switch also supports Cisco Network Plug and Play for provisioning, plus TFTP and SCP for firmware and configuration file handling.
CBS250-24P-4G is end-of-sale, with Cisco’s last order date on 31 January 2025. Phone support, software maintenance releases, and vulnerability support ended on 31 January 2026, while last date of support is 31 October 2029. The named migration product is C1200-24P-4G.
ORM Systems offers CBS250-24P-4G new sealed or certified refurbished, with new units eligible for up to a 3-year extended warranty and certified refurbished units eligible for up to 1 year. Cisco’s platform warranty is Limited Lifetime with service ending 31 October 2029. Returns are 30 days on every condition; terms apply.
CBS250-24P-4G does not require a network license tier or software subscription for the smart-switch feature set. The SKU ships as a smart managed switch with embedded switching, security, management, PoE, and static routing capabilities, so license selection is not a separate purchasing step.
CBS250-24P-4G provides a 195W PoE budget across 24 PoE+ RJ-45 ports. Each powered port can deliver up to 30W until the shared budget is reached, so a full 24-port deployment must be sized by endpoint draw rather than by port count alone.
CBS250-24P-4G has four fixed Gigabit SFP uplink ports. Supported 1G transceiver PIDs include MGBSX1, MGBLH1, MGBLX1, MGBT1, GLC-SX-MMD, GLC-LH-SMD, GLC-BX-U, GLC-BX-D, and GLC-TE. SFP optics are separate from the switch, power cord, mounting kit, and quick start guide package.
No, CBS250-24P-4G supports four 1G SFP uplinks rather than 10G SFP+ uplinks. The same family includes CBS250-24P-4X with four 10 Gigabit SFP+ uplinks, and that discontinued sibling migrates to C1200-24P-4X for current ordering. Use the 4X path when aggregation ports require 10G handoff instead of four Gigabit fiber links.
Yes, CBS250-24P-4G supports Layer 3 static routing between interfaces, including wire-speed IPv4 routing with up to 32 static routes and up to 16 IP interfaces. IPv6 routing, CIDR, DHCP relay, and UDP relay are also present; dynamic routing protocols are not part of this smart-switch tier.
Yes, CBS250-24P-4G is fanless and rack-mountable in a 1U 19-inch width. The chassis measures 445 mm wide, 299 mm deep, and 44 mm high, with a 3.53 kg unit weight. The package includes the switch, power cord, mounting kit, and quick start guide.
CBS250-24P-4G replaced regional SF250-24P-K9 and SG250-26P-K9 PoE smart-switch PIDs. The affected older PIDs include SF250-24P-K9-AR, SF250-24P-K9-AU, SF250-24P-K9-BR, SG250-26P-K9-AU, SG250-26P-K9-BR, SG250-26P-K9-EU, SG250-26P-K9-IN, SG250-26P-K9-NA, and SG250-26P-K9-UK, all with 30 October 2021 end-of-sale.
CBS250-24P-4G has a 195W PoE budget, while CBS250-24PP-4G has a 100W PoE budget on the same 24 10/100/1000 PoE+ and four Gigabit SFP layout. The 24P model fits higher aggregate endpoint draw; the 24PP model fits lighter PoE loads on the discontinued family.
CBS250-24P-4X has four 10 Gigabit SFP+ uplinks, while CBS250-24P-4G has four Gigabit SFP uplinks with the same 24 10/100/1000 PoE+ ports and 195W PoE budget. The 4X model fits 10G aggregation; the 4G model fits Gigabit fiber uplinks.
C1200-24P-4G is the current migration PID for CBS250-24P-4G, and the older Business 250 model is end-of-sale. Both descriptions keep 24 Gigabit PoE+ access ports, a 195W PoE budget, and four 1G SFP uplinks. Choose C1200 for current standardization; keep CBS250 for installed-base sparing.
