CBS250-48T-4G-EU is a Layer 2+ 48-port Gigabit smart switch with copper access connections and four fixed 1G SFP uplinks for small-business networks. Its non-PoE access connections serve computers, printers and servers with their own power, while phones and access points require separate power arrangements. The full-width 1U chassis places the Cisco Business 250 in an equipment rack rather than on a desktop. CBS250-48P-4G-EU, also discontinued, adds PoE+ output with a shared 370W budget for powered endpoints. Dedicated uplinks leave the copper access connections available for local devices.

104 Gbps switching capacity provides nonblocking forwarding across the installed interfaces, while 77.38 Mpps forwarding at a 64-byte packet size defines the packet-processing ceiling. Static IPv4 routing supports 32 routes for manually maintained paths between local networks; dynamic routing is not available. STP/RSTP/MSTP provide loop-control options, and LACP groups links for aggregated connections. Up to 255 active VLANs separate workgroups, with eight hardware queues and strict-priority or weighted round-robin scheduling controlling traffic treatment. CBS250-48T-4G-EU carries 512 MB DRAM and 256 MB flash for its embedded software and configuration storage. A dynamically shared 3 MB packet buffer serves the ports rather than assigning a separate fixed buffer to each connection. Local administration uses the browser interface or scriptable CLI, including the dedicated RJ-45 console. 48.64W maximum system consumption supplies the upper draw figure for circuit sizing, and one fan provides active cooling rather than silent operation.
Order CBS250-48T-4G-EU new sealed or certified refurbished, specifying condition, regional power cord and transceivers on the PO. Certified refurbished units are inspected and bench-tested, including optics bay recognition, with firmware verified and configuration wiped to factory default. ORM covers new units with up to a 3-year extended warranty and refurbished units for up to 1 year; every condition has 30-day returns, terms apply, while Cisco's separate, eligibility-dependent limited lifetime warranty ends October 31, 2029. Enterprise and volume orders support PO acceptance, Net-30 for government and RMA with advance replacement, with regional stock/RMA across UK, EU, US and MEA.

When several small-business sites need a common administration workflow, the embedded Cisco Business Dashboard probe removes the need for a separate probe appliance or virtual machine at each site. Confirm Dashboard connectivity and the management network design before standardizing the rollout purchase order.
When separate workgroups need local communication, the switch can host 16 IP interfaces on physical ports, link aggregation groups, VLAN interfaces or loopback interfaces. Map the intended interfaces and upstream responsibilities before purchase, then include the required addressing and interface plan with the order.
When a lab or staging bench needs packet captures before release, port mirroring can copy traffic from four source ports to one destination port. Reserve the analyzer connection and identify the source interfaces in the test plan before ordering the switch and associated cabling.
10G uplinks to distribution
Fixed uplinks stop at 1G and cannot accept a 10G uplink card. C1200-48T-4X provides 48 Gigabit access ports with four 10G SFP+ uplinks.
Ethernet power for connected endpoints
RJ-45 access ports carry data without PoE output, so phones and access points need separate power. C1200-48P-4G is the current 48-port PoE alternative.
Continuing Cisco security maintenance
Security support ended October 29, 2025, so this model cannot meet a requirement for continuing Cisco security remedies. C1200-48T-4G is the current replacement.

CBS250 identifies the Cisco Business 250 smart-switch family, 48T denotes 48 non-PoE Gigabit copper ports, 4G denotes four Gigabit SFP uplinks, and EU is the regional ordering suffix. The EU code covers the European Economic Area and additional designated markets; it is not a software license tier.
CBS250-48T-4G-EU supports browser management over HTTP/HTTPS, CLI access through SSH, Telnet or the RJ-45 console, Cisco Business Dashboard, the Cisco Business mobile app, and SNMP. Dashboard can use the embedded probe without a separate probe appliance. Cisco Network Plug and Play also supports provisioning.
CBS250-48T-4G-EU is discontinued: end of sale was October 29, 2024, and software maintenance and vulnerability/security support ended October 29, 2025. The last date of Cisco support is October 31, 2029. C1200-48T-4G is the current replacement for purchases that do not require matching an existing Business 250 installation.
ORM Systems offers CBS250-48T-4G-EU new sealed or certified refurbished, with up to a 3-year extended warranty on new units and up to 1 year on refurbished units. Both conditions include 30-day returns, terms apply. Cisco's separate limited lifetime warranty remains subject to eligibility and ends no later than October 31, 2029.
CBS250-48T-4G-EU replaces SG250-50-K9-EU and SF250-48-K9-EU. SG250-50-K9-EU reached end of sale on October 30, 2021, while SF250-48-K9-EU reached end of sale on July 30, 2022. Both predecessors are discontinued, and the Business 250 replacement is also past end of sale, making lifecycle requirements important when matching an older installation.
The Cisco Business 250 supports MGBSX1 for multimode fiber links to 500 m and MGBLX1 for single-mode fiber links to 10 km. These are 1G transceiver options for the fixed SFP uplinks. Order the required transceivers separately and match fiber type, distance and the equipment at the opposite end.
CBS250-48T-4G-EU reaches 48.64W worst-case system consumption at 220V AC and 48.27W at 110V AC. Its internal supply accepts 100-240V AC, and the chassis does not provide redundant power supplies. These consumption figures cover the switch itself because this non-PoE model supplies no endpoint power.
CBS250-48T-4G-EU is a full-width 1U rack-mount switch measuring 445 mm wide, 288 mm deep and 44 mm high, with a weight of 3.95 kg. A mounting kit is included with the original package. The chassis uses one cooling fan, so installation planning must allow for active cooling.
The Cisco Business 250 supports inter-VLAN communication through static IPv4 routing, with 32 static routes and 16 IP interfaces. Interfaces can use physical ports, link aggregation groups, VLAN interfaces or loopback interfaces. This is Layer 2+ functionality with manually maintained routing, not a dynamic-routing feature set.
The Cisco Business 250 assigns voice traffic to a voice VLAN and supports eight hardware queues for traffic prioritization. Scheduling options include strict priority and weighted round-robin, with classification using port settings, VLAN priority or IP traffic markings. Voice prioritization does not add PoE capability to a non-PoE model.
CBS250-48T-4G-EU provides no PoE output, while CBS250-48P-4G-EU provides PoE+ with a shared 370W budget across its access ports. Both models are discontinued. The non-PoE configuration matches independently powered endpoints, while the PoE configuration matches endpoints drawing power over Ethernet within the available shared budget.
CBS250-48T-4G-EU has four 1G SFP uplinks, whereas CBS250-48T-4X-EU has four 10G SFP+ uplinks. Both models are discontinued and retain Gigabit copper access connections. The 4G configuration matches existing Gigabit distribution links; the 4X configuration matches installations whose distribution connections require 10G.
CBS250-48T-4G-EU is discontinued, while C1200-48T-4G is its current replacement; both provide 48 Gigabit copper ports and four 1G SFP uplinks. The Business 250 unit matches existing estates and sparing requirements, whereas the Catalyst 1200 model suits new purchases requiring the current replacement rather than a discontinued generation.
CBS250-48T-4G-EU provides 104 Gbps switching capacity and 77.38 Mpps forwarding for 64-byte packets. A 3 MB packet buffer is dynamically shared across the ports. Switching bandwidth, packet rate and buffer capacity describe different limits, so traffic sizing should consider packet sizes and burst behavior rather than bandwidth alone.
