CBS250-24T-4X-NA combines fanless cooling with 24 Gigabit Ethernet access ports and four fixed 10G SFP+ uplinks in a Layer 2+ smart-managed switch. The Cisco Business 250 Series serves small-business wired networks connecting computers, printers, servers, and separately powered communications devices. A full-width 1U chassis fits a standard equipment rack. The CBS250-24T-4X does not supply PoE, so connected phones, cameras, and access points require independent power. The discontinued CBS250-24P-4X-NA adds PoE+ delivery for installations that require Ethernet-powered endpoints. Fixed uplink cages leave the copper access connections available for endpoint devices rather than consuming them for upstream links. Support for 1G operation in those cages also accommodates existing Gigabit fiber connections during a staged transition to higher-speed uplinks, provided compatible link media is specified at both ends.
CBS250-24T-4X-NA price for new stock is $853.65. CBS250-24T-4X-NA refurb price is $406.35. CBS250-24T-4X-NA is in stock and available for next-day dispatch. (terms applied)

128 Gbps switching capacity supports nonblocking traffic across the access connections and uplinks. 95.23 Mpps forwarding at 64-byte packet size provides the packet-rate reference for small-packet traffic planning. Static IPv4 routing supports 32 routes for manually defined paths between subnets; dynamic routing is not available. CBS250-24T-4X-NA combines 512 MB of DRAM with 256 MB of flash, separating operating memory from image storage. An 800 MHz ARM CPU handles control functions, while a shared 1.5 MB packet buffer accommodates traffic bursts across the ports. STP, RSTP, and MSTP provide spanning-tree choices, and LACP supports link aggregation. Browser-based configuration, a scriptable CLI, and SNMP support local administration and monitoring. Administrators can use SSH for encrypted command access and HTTPS for encrypted browser sessions. An 8000-entry MAC table defines learned-address capacity. Worst-case consumption of 27.54W provides a reference for AC circuit and UPS sizing without allocating electrical capacity for endpoint power delivery.
ORM Systems offers CBS250-24T-4X-NA new sealed or certified refurbished; refurbished units are inspected and bench-tested for power-on and POST, clean boot, rated-speed port links, optics bay recognition, and PSU status, with firmware verified and configuration wiped to factory default. Specify condition, quantity, and required link media on the PO. New units carry up to 3-year extended ORM warranty and certified refurbished units up to 1 year; both have 30-day returns, terms apply, while Cisco's limited lifetime hardware warranty is eligibility-dependent and bounded by October 31, 2029. For enterprise and volume orders, PO acceptance, Net-30 for government, RMA with advance replacement, and regional stock/RMA across the UK, EU, US, and MEA are available.

When an SG250X-24-K9-NA needs replacement within its hardware migration line, this model is the next step. The older switch reached end of sale on October 30, 2021. Before issuing the PO, match the existing configuration, regional power connection, and link media to the replacement order.
When additional local subnets must connect without moving every path to an upstream router, the limit of 16 IP interfaces becomes an ordering constraint. Map the required physical-port, VLAN, link-aggregation, and loopback interfaces before purchase, then confirm that the planned interface count fits the configuration.
When several branches need the same initial configuration, Cisco Network Plug and Play and PnP Connect support repeatable provisioning. An embedded Cisco Business Dashboard probe removes the need for a separate probe host at each site. Specify the provisioning workflow and Dashboard arrangements before releasing the branch purchase orders.
Ethernet power for connected devices
CBS250-24T-4X-NA supplies data connectivity without PoE output. C1200-24P-4X is the current migration option for the discontinued powered sibling, retaining 24 Gigabit access ports and four 10G uplinks.
Continuing vendor security maintenance
Vulnerability/security support ended October 29, 2025, so this model no longer receives scheduled security remedies. C1200-24T-4X is the current migration model for purchases moving beyond this discontinued hardware.
More than 32 static routes
IPv4 routing is limited to 32 static routes, with 16 IP interfaces. A network requiring a larger local routing table exceeds this switch's supported routing configuration.

CBS250-24T-4X-NA identifies a Cisco Business 250 smart switch: 24 denotes 24 access ports, T identifies the data-only copper configuration, and 4X denotes four 10G SFP+ uplinks. NA is the regional ordering suffix covering the United States, Canada, Mexico, Colombia, Chile, and the rest of Latin America.
CBS250-24T-4X-NA is managed through its HTTP/HTTPS web interface, CLI over SSH or Telnet, RJ-45 console, Cisco Business Dashboard, Cisco Business mobile app, and SNMP. The embedded Dashboard probe avoids a separate probe appliance, while Cisco Network Plug and Play supports provisioning. Full and menu-based CLI modes are available.
CBS250-24T-4X-NA reached end of sale on October 29, 2024, and software maintenance plus vulnerability/security support ended October 29, 2025. Eligible hardware support continues until October 31, 2029. C1200-24T-4X is the current migration model, so existing-fleet replacement and new deployments require different lifecycle decisions.
CBS250-24T-4X-NA is offered new sealed or certified refurbished, with ORM warranty coverage of up to 3-year extended for new units and up to 1 year for refurbished units. Every condition has 30-day returns; terms apply. Cisco's limited lifetime hardware warranty is subject to eligibility and ends no later than October 31, 2029.
CBS250-24T-4X-NA replaces SG250X-24-K9-NA, the discontinued 24-port Gigabit smart switch with 10G uplinks. SG250X-24-K9-NA reached end of sale on October 30, 2021. This replacement relationship identifies the hardware migration step, but the newer CBS250 model has also reached end of sale.
The Business 250 24-port 10G-uplink switch accepts SFP-10G-SR for multimode fiber, SFP-10G-LR for single-mode fiber, and SFP-H10GB-CU3M for a 3 m direct-attach connection. Its four fixed SFP+ cages support 10G and 1G operation. Specify compatible media for both ends of each link; empty cages do not include optical connections.
The Business 250 series supports IPv4 static routing with 32 routes and 16 IP interfaces. Those interfaces can attach to physical ports, link-aggregation groups, VLAN interfaces, or loopback interfaces. Plan manually maintained paths and interface usage before assigning local subnet gateways to the switch.
Yes, the Business 250 24-port 10G-uplink switch uses a full-width 1U chassis measuring 445 mm wide, 240 mm deep, and 44 mm high, weighing 2.78 kg. A mounting kit is included. Allow ventilation around the fanless enclosure and keep operation within -5°C to 50°C.
CBS250-24T-4X-NA uses an internal universal AC supply accepting 100-240V AC at 50-60 Hz. The fixed supply does not provide a second internal redundancy option. Worst-case system consumption is 27.54W at 110V and 27.25W at 220V, so facility power planning should use the applicable input condition.
CBS250-24P-4X-NA adds PoE+ on 24 access ports with a shared 195W budget, while CBS250-24T-4X-NA supplies no endpoint power. Both are discontinued. The data-only model suits separately powered devices; the powered variant suits legacy installations needing Ethernet power within its budget. C1200-24P-4X is the migration model for new powered purchases.
CBS250-24T-4X-NA has four 10G SFP+ uplinks, whereas CBS250-24T-4G-NA has four 1G SFP uplinks. Both are discontinued and provide 24 Gigabit copper access ports. The 4X configuration suits existing installations needing higher-speed upstream connections; the 4G configuration fits legacy installations whose upstream links remain restricted to Gigabit.
C1200-24T-4X is the current migration model for discontinued CBS250-24T-4X-NA, retaining 24 Gigabit copper ports and four 10G SFP+ uplinks. Their lifecycle positions differ without changing those port counts. CBS250-24T-4X-NA suits a matching legacy replacement order; C1200-24T-4X suits a purchase intended to move to the current product line.
