Cisco CBS250-48T-4G 48-Port Gigabit Smart Managed Switch 4x 1G SFP L2/L3 New

The Cisco CBS250-48T-4G (NA) is a 48-port Gigabit Ethernet Smart Managed Switch with 4x 1G SFP fiber uplinks, built for small and mid-size business networks, branch offices, and access-layer deployments. Part of the Cisco Business 250 Series, it delivers 104 Gbps switching capacity, 77.38 Mpps forwarding, Layer 2 switching with Layer 3 static routing for inter-VLAN traffic, plus VLAN segmentation and QoS for voice and video — all configurable through a simple web GUI or the Cisco Business Dashboard. This is a non-PoE model — for PoE+ output, see the CBS250-48P-4G or CBS250-48PP-4G variants.

Cisco CBS250-48T-4G - Key Features & Benefits
  • 48 Gigabit RJ-45 + 4x 1G SFP Uplinks: 48x 10/100/1000BASE-T access ports plus 4x 1G SFP fiber uplinks for backbone aggregation, IDF-to-MDF runs, and multi-switch deployments.
  • Smart Managed with Layer 3 Static Routing: 104 Gbps switching capacity and 77.38 Mpps forwarding (wire-speed, non-blocking); supports up to 255 active VLANs, STP/RSTP/MSTP, LACP link aggregation, and IPv4/IPv6 static routing with up to 32 static routes and 16 IP interfaces for inter-VLAN traffic.
  • QoS for Voice, Video & Data: 8 hardware queues with Auto Voice VLAN, 802.1p and DSCP traffic prioritization, plus jumbo frame support — suited to small-business VoIP, video conferencing, and surveillance traffic.
  • Network Security at the Access Layer: 802.1X port authentication, RADIUS, port security, up to 512 ACLs, storm control, and DoS attack prevention protect against rogue devices and common LAN attacks.
  • Easy Management — Web GUI, SNMP, Cisco Business Dashboard: Configure via HTTPS web interface, SNMP v1/v2c/v3, or SSH CLI; deploy and monitor multiple switches centrally with the free Cisco Business Dashboard and mobile app.

Cisco CBS250-48T-4G - Frequently Asked Questions (FAQ)
  • Does this switch support PoE or PoE+?
    No — the CBS250-48T-4G is a non-PoE model. To power IP phones, APs, and cameras over the same cable, use the CBS250-48P-4G (370W PoE+ budget) or CBS250-48PP-4G (195W partial PoE+) instead.
  • What is the difference between the CBS250-48T-4G and the CBS250-48T-4X?
    Both are 48-port Gigabit smart switches with no PoE. The -4G has 4x 1G SFP uplinks; the -4X has 4x 10G SFP+ uplinks with higher overall switching capacity (176 Gbps vs 104 Gbps) for higher-bandwidth backbones.
  • Does it support full Layer 3 routing or stacking?
    It supports IPv4 and IPv6 static routing only (up to 32 routes, 16 IP interfaces) for inter-VLAN traffic — no dynamic routing protocols such as OSPF, RIP, or BGP. There is no physical stacking, but multiple switches can be deployed and monitored centrally through the Cisco Business Dashboard.
