CBS250-48P-4G-NA is a smart-managed, Layer 2+ access switch with 48 Gigabit Ethernet PoE+ ports and four fixed Gigabit SFP uplinks. The Business 250 configuration serves small-business networks connecting computers, IP phones, wireless access points, and cameras. Its full-width 1U chassis fits a standard equipment rack, while separate fiber uplinks leave the copper access connections available for endpoints. Uplink expansion requires a different hardware configuration rather than an add-in network card. The discontinued CBS250-48PP-4G-NA is the closest lower-power sibling, offering a 195W PoE budget rather than this model's higher allocation. For an existing installation, distinguish endpoint connection requirements from endpoint power requirements before choosing between those configurations.
CBS250-48P-4G-NA price for new stock is $1,025.85, a 27.6% saving from the Cisco list price of $1,417.50. CBS250-48P-4G-NA refurb price is $477.75. CBS250-48P-4G-NA is in stock and available for next-day dispatch. (terms applied)

104 Gbps switching capacity and 77.38 Mpps forwarding provide the throughput figures for traffic planning. 370W of shared PoE power requires an endpoint-by-endpoint allocation rather than assuming every powered connection can operate at its individual maximum simultaneously. Static IPv4 routing supports 32 routes and 16 IP interfaces for a bounded inter-VLAN routing configuration. CBS250-48P-4G-NA carries 512 MB DRAM and 256 MB flash; its 3 MB packet buffer is shared across the ports. STP, RSTP, and MSTP provide spanning-tree options, while LACP supports aggregated Ethernet links. Keep topology protection and link aggregation settings consistent with the neighboring equipment during staging. A front-panel USB Type-A connection supports file and image handling, and the RJ-45 console provides local administrative access. Hardware stacking is not supported, so multiple units remain separate switches rather than members of a single stack.
Order CBS250-48P-4G-NA new sealed or certified refurbished, and state the required condition and accessory PIDs on the PO. Certified refurbished units are inspected and bench-tested for power-on and POST, rated-speed links on every port, clean boot, PoE output under load on every powered port, optics bay recognition, PSU status, and fan status; firmware is verified and the configuration is wiped to factory default. New orders carry up to a 3-year extended warranty, certified refurbished orders up to 1 year, and every condition has 30-day returns with terms applying. Enterprise and volume orders can use PO acceptance, Net-30 for government, and RMA with advance replacement across UK, EU, US, and MEA.

An installation retaining SG250-50P-K9-NA equipment has a named migration path to this configuration. The older model reached end of sale on October 30, 2021. Treat the replacement as a planned hardware change rather than an interchangeable spare: record the existing connections and configuration requirements, then specify the required condition before the PO.
A rollout with multiple traffic groups and access policies should be staged before shipment. The series supports 255 active VLANs and 512 ACL rules, giving the configuration team explicit limits to check against its design. Build the intended VLAN and policy configuration, test the required traffic paths, and approve the configuration scope before ordering.
A multi-site purchase using centralized provisioning can use the Cisco Network Plug and Play agent with Cisco PnP Connect. That provisioning requirement is separate from selecting the hardware condition. Identify the destination sites, establish who owns onboarding, and confirm the intended provisioning workflow during staging before issuing the deployment purchase order.
10G uplinks to distribution
The fixed SFP uplinks operate at 1G. C1200-48P-4X is the current migration option for the discontinued 10G-uplink variant and retains 48 Gigabit PoE access ports.
Maximum PoE power on every port
The shared power allocation cannot supply every powered port at its individual maximum simultaneously. Size the combined endpoint demand before selecting this configuration for a fully loaded installation.
Fanless operation in occupied spaces
The chassis uses one cooling fan rather than passive cooling. A procurement requirement for fanless equipment excludes this configuration, even when the intended installation is a small office.

CBS250-48P-4G-NA identifies the Business 250 family, 48 Gigabit copper ports, PoE+ capability, four Gigabit SFP uplinks, and the NA regional ordering version. The NA suffix covers the United States, Canada, Mexico, Colombia, Chile, and the rest of Latin America; it is not a software-license tier.
The Cisco Business 250 switch supports a browser-based web interface, CLI access through the console or SSH/Telnet, SNMP, Cisco Business Dashboard, and the Cisco Business mobile app. Select the administrative method during staging and establish the intended credentials and access controls before introducing the switch into production.
Yes, CBS250-48P-4G-NA reached end of sale on October 29, 2024. Software maintenance and vulnerability support ended October 29, 2025, while the last date of support is October 31, 2029. C1200-48P-4G is the replacement for buyers specifying a current migration model.
ORM offers CBS250-48P-4G-NA new sealed with up to a 3-year extended warranty, or certified refurbished with up to a 1-year warranty. Returns are available for 30 days on every condition; terms apply. Cisco's Limited Lifetime warranty is separate, with applicable Cisco service ending October 31, 2029.
No separate switch feature license or subscription is required for CBS250-48P-4G-NA; switch functionality comes with the hardware purchase. There is no enterprise network-tier selection to add to this part number. Keep the PO focused on the required hardware condition, physical connections, and installation accessories.
CBS250-48P-4G-NA replaces SG250-50P-K9-NA, which reached end of sale on October 30, 2021. That migration relationship helps identify the intended hardware refresh, but the replacement has also been discontinued. For a current-generation purchase rather than legacy hardware continuity, the forward replacement is C1200-48P-4G.
CBS250-48P-4G-NA provides a shared 370W PoE budget across 48 powered ports, with an individual-port maximum of 30W. The individual-port rating does not guarantee simultaneous maximum output on every connection. Add the intended endpoint demands and allow for the required allocation before approving the powered-device schedule.
The Business 250 Gigabit SFP uplinks support options including GLC-SX-MMD for multimode fiber and GLC-LH-SMD for single-mode fiber. Match the transceiver to the installed fiber and the remote connection. State the selected PID on the order so the required physical link is specified separately from the switch.
Yes, CBS250-48P-4G-NA supports static IPv4 routing with 32 routes and 16 IP interfaces. That makes its routing classification Layer 2+, rather than a dynamic-routing enterprise tier. Check the intended route and interface requirements before purchase, and retain the external router for the functions assigned to it in the network design.
No, Cisco Business 250 switches do not support hardware stacking. Centralized management does not turn separate switches into a hardware stack or a shared forwarding system. Plan each unit as an individual switch, and do not add a stack kit or stacking cables to the hardware order.
CBS250-48P-4G-NA has a 370W PoE budget, whereas CBS250-48PP-4G-NA has 195W. Both models are discontinued, and no current migration product is named for the lower-budget model. The higher-budget configuration suits an existing installation needing more aggregate endpoint power; the lower-budget configuration addresses a smaller aggregate load.
CBS250-48P-4G-NA has four 1G SFP uplinks, whereas CBS250-48P-4X-NA has four 10G SFP+ uplinks. Both are discontinued. The first matches a legacy Gigabit-uplink installation; buyers requiring the faster uplink configuration on a current migration model should specify C1200-48P-4X rather than the discontinued 4X model.
CBS250-48P-4G-NA is discontinued, while C1200-48P-4G is its current replacement. The migration configuration retains 48 Gigabit PoE access ports and four Gigabit SFP uplinks. The older part addresses purchases tied to installed Business 250 equipment; the replacement is the model to specify for a current-generation refresh.
