CBS250-48T-4G-NA is a smart managed Layer 2+ access switch with 48 Gigabit Ethernet RJ-45 ports and four fixed 1G SFP uplinks for small-business networks. The non-PoE configuration connects independently powered computers, printers and servers in a 1U rack-mount chassis. Within the Cisco Business 250 Series, dedicated optical interfaces leave the copper connections available for endpoints rather than sharing combo ports. The discontinued CBS250-48PP-4G-NA adds PoE+ with a 195W shared budget, distinguishing that powered configuration from this data-only version. Cisco Business networks can also use voice VLAN and QoS functions to separate and prioritize delay-sensitive traffic.
CBS250-48T-4G-NA price for new stock is $553.35, a 34.6% saving from the Cisco list price of $845.63. CBS250-48T-4G-NA refurb price is $311.85. CBS250-48T-4G-NA is in stock and available for next-day dispatch. (terms applied)

104 Gbps switching capacity supports nonblocking traffic handling, while 77.38 Mpps forwarding specifies performance with 64-byte packets. 32 static routes and 16 IP interfaces bound local inter-VLAN routing; dynamic routing is not provided. CBS250-48T-4G-NA uses 512 MB of DRAM and 256 MB of flash, with a 3 MB packet buffer shared across its ports. The MAC table accommodates 8000 addresses, and 255 active VLANs provide separate endpoint groups. STP/RSTP/MSTP and LACP support loop control and link aggregation, but hardware stacking is unavailable. Administrators can use browser configuration, CLI over SSH or Telnet, the RJ-45 console, SNMP, Cisco Business Dashboard or the Cisco Business mobile app. A USB Type-A slot supports local file and image handling. 48.64W worst-case consumption at 220V AC provides a circuit-planning figure. One fan supplies cooling across the operating range of -5°C to 50°C.
ORM Systems offers CBS250-48T-4G-NA new sealed with up to a 3-year extended warranty or certified refurbished with up to 1 year; 30-day returns apply to every condition, with terms applying. Certified refurbished units are inspected and bench-tested: every port links at rated speed, optics bay recognition is checked, firmware is verified, and configurations are wiped to factory default. Specify the condition, quantity and included accessories on your purchase order; Cisco's separate limited lifetime hardware warranty remains subject to eligibility and ends October 31, 2029. For enterprise and volume orders, ORM accepts POs, offers government Net-30 terms and RMA with advance replacement, and provides regional stock/RMA coverage across the UK, EU, US and MEA.

When replacing a discontinued SG250-50-K9-NA, treat the purchase as a controlled hardware substitution rather than copying every existing setting unchanged. Record the installed configuration, identify required network behavior and schedule validation against the existing environment. Specify the replacement quantity and configuration acceptance checks before issuing the purchase order.
When several locations need the same initial configuration, text-editable configuration files can be downloaded to other switches, and CLI access supports privilege levels 1, 7 and 15. Establish which settings are shared and which remain site-specific. Specify approved configuration files, administrator access levels and staging checks with the hardware order.
When a troubleshooting bench needs traffic visibility before equipment enters service, port mirroring supports four source ports feeding one destination port. Allocate that destination connection to the analyzer rather than an endpoint. Define the capture connections, test traffic and acceptance criteria before specifying the staging equipment on the purchase order.
10G uplinks to distribution
CBS250-48T-4G-NA has 1G SFP uplinks, not 10G uplinks. C1200-48T-4X is the current 10G-uplink alternative and retains 48 Gigabit access ports.
Ethernet power for connected endpoints
CBS250-48T-4G-NA supplies no PoE. C1200-48P-4G is the current powered alternative with 48 Gigabit access ports and four 1G SFP uplinks; size endpoint power separately.
More than 32 static routes
CBS250-48T-4G-NA supports 32 static routes and 16 IP interfaces, so larger routing configurations exceed its supported capacity even when physical access ports remain available.

CBS250-48T-4G-NA identifies a Cisco Business 250 switch: CBS250 names the family, 48 is the copper access-port count, T denotes the non-PoE copper configuration, and 4G identifies four Gigabit SFP uplinks. NA is the regional suffix covering the United States, Canada, Mexico, Colombia, Chile and other Latin American markets.
CBS250-48T-4G-NA supports a web UI, CLI through SSH or Telnet, an RJ-45 console, SNMP, Cisco Business Dashboard and the Cisco Business mobile app. Browser access supports HTTP or HTTPS. The embedded Dashboard probe allows centralized management without installing a separate probe appliance or virtual machine at the site.
CBS250-48T-4G-NA is discontinued: end of sale was October 29, 2024, and the last date of support is October 31, 2029. Software maintenance and vulnerability/security support ended October 29, 2025. C1200-48T-4G is the current replacement; remaining hardware support eligibility does not mean ongoing security fixes for the older model.
ORM offers CBS250-48T-4G-NA new sealed with up to a 3-year extended warranty or certified refurbished with up to 1 year. Returns are 30 days for either condition; terms apply. Cisco's limited lifetime hardware warranty is separate, subject to eligibility, and ends October 31, 2029; software and security support ended October 29, 2025.
No separate license or subscription is required for CBS250-48T-4G-NA; its included functions are available with the hardware purchase. There are no network-tier choices or minimum subscription terms to add to this switch order. Select the required hardware configuration rather than a separate software-unlock package.
CBS250-48T-4G-NA replaces the discontinued SG250-50-K9-NA and SF250-48-K9-NA. SG250-50-K9-NA reached end of sale October 30, 2021; SF250-48-K9-NA reached end of sale July 30, 2022. Preserve the existing configuration inventory and validate the replacement setup rather than treating either former model as a current purchase alternative.
CBS250-48T-4G accepts 1G SFP transceivers, including MGBSX1 for multimode fiber and MGBLX1 for single-mode fiber. MGBSX1 supports 500 m, while MGBLX1 supports 10 km. Select the transceiver against fiber type and link distance, and include the required optics separately in the hardware order.
CBS250-48T-4G-NA provides static IPv4 routing with up to 32 routes and 16 IP interfaces. Static entries can support traffic between VLANs, but routes are configured explicitly rather than learned dynamically. Check the required route entries and addressed interfaces before ordering; available physical ports do not expand those routing limits.
No, Cisco Business 250 switches do not support hardware stacking. Cisco Business Dashboard can manage multiple switches, but centralized management does not create a shared forwarding system or stack interconnect. Plan each unit as an independent switch rather than ordering stacking cables for this series.
No, CBS250-48T-4G-NA does not support redundant power supplies; an internal AC supply powers the switch. The input range is 100–240V AC at 50–60 Hz, and no external AC adapter is required. Specify the appropriate power cord and do not add a second internal power supply to the order.
The Cisco Business 250-48T-4G Smart Switch occupies 1U and measures 445 mm wide, 288 mm deep and 44 mm high, with a weight of 3.95 kg. A mounting kit accompanies the original package. Check cabinet depth and cable clearance, and confirm mounting hardware with the ordered condition.
CBS250-48PP-4G-NA provides 48 PoE+ ports with a 195W shared budget, whereas CBS250-48T-4G-NA supplies no endpoint power. Both models are discontinued, and the partial-PoE model has no current migration successor. The unpowered version suits data-only replacements; the powered version suits matching an existing installation whose endpoint demand fits its budget.
CBS250-48T-4X-NA carries four 10G SFP+ uplinks, whereas CBS250-48T-4G-NA has four 1G SFP uplinks. Both models are discontinued. The 1G version suits like-for-like replacements; the 10G version suits retaining installed higher-speed uplinks, with C1200-48T-4X serving as its current migration choice for buyers moving to a current model.
C1200-48T-4G is the current replacement for discontinued CBS250-48T-4G-NA, retaining 48 Gigabit access ports and four 1G SFP uplinks. The older model reached end of sale October 29, 2024. CBS250-48T-4G-NA suits matching an installed Business 250 estate; C1200-48T-4G suits new purchases requiring a currently orderable successor.
