Cisco CBS220-24T-4G - 24-Port Gigabit Layer 2 Smart Managed Switch | 4x 1G SFP Uplinks - Cisco Refresh

The Cisco CBS220-24T-4G is a 24-port Gigabit Ethernet Layer 2 Smart Managed Switch from the Cisco Business 220 Series, built for small business networks, branch offices, classrooms, and converged voice/data access deployments. It pairs 24 Gigabit RJ-45 access ports with 4 dedicated 1G SFP uplinks, delivering 56 Gbps switching capacity and a 41.66 Mpps forwarding rate in a fanless 1U rack-mount chassis. This is a Layer 2-only switch with no IP routing and no PoE — inter-VLAN routing must be performed by an upstream router or Layer 3 switch, and connected devices (IP phones, access points, cameras) must be self-powered or supplied by a separate PoE injector or PoE switch. As a Cisco Refresh certified remanufactured unit, it carries genuine Cisco firmware and original Cisco serial numbers, tested by Cisco to original factory specifications.

Cisco CBS220-24T-4G - Key Features & Benefits

• Layer 2 Access Switch — 24 Gigabit Ports + 4 SFP Uplinks: 24 x 10/100/1000BASE-T RJ-45 ports for client connectivity plus 4 x 1G SFP slots for fiber or copper uplinks. Layer 2-only — IP routing must be handled by a router or Layer 3 switch upstream
• Fanless Silent Operation — 56 Gbps Switching: Non-blocking 56 Gbps switching capacity and 41.66 Mpps forwarding rate per the Cisco datasheet, in a fanless 1U chassis ideal for offices, classrooms, and quiet workspaces
• Web GUI, CLI & Cisco Business Dashboard: Browser-based configuration via HTTP/HTTPS, command-line interface (CLI), and SNMP v1/v2c/v3. CBS220 connects directly to Cisco Business Dashboard, "eliminating the need to set up separate hardware or a virtual machine on site" per the Cisco datasheet (a CBD account/instance is still required)
• Advanced VLAN, QoS & Security: Up to 256 VLANs, Auto Voice VLAN, 8 hardware QoS queues per port, 802.1X authentication, ACLs (up to 512 rules), storm control, BPDU Guard, and DoS protection
• Multicast, Resiliency & Power Efficiency: IGMP v1/v2/v3 snooping with 256 multicast groups, RSTP/MSTP fast convergence, LACP link aggregation (up to 8 groups, 8 ports per group), and 802.3az Energy Efficient Ethernet on all ports

Cisco CBS220-24T-4G - Frequently Asked Questions (FAQ)

• Does this switch provide PoE to connected devices?
  No. The CBS220-24T-4G is the non-PoE variant — the data ports do not source power. IP phones, wireless access points, and IP cameras connected to this switch must be self-powered or fed by a separate PoE injector or PoE switch. If you need PoE+ on the same chassis platform, choose the CBS220-24P-4G (195W budget) or CBS220-24FP-4G (382W budget).
• Does this switch support IP routing or inter-VLAN routing?
  No. The CBS220 series is Layer 2 only and does not perform IP routing or inter-VLAN routing per Cisco's product comparison documentation. To route between VLANs, use an upstream router or a Layer 3 switch (the Cisco CBS250 supports basic static routing; the CBS350 supports full Layer 3).
• What SFP modules work with the 4 uplink ports?
  The 4 SFP slots accept 1G SFP modules only. Per the Cisco datasheet, the officially listed compatible modules include MGBSX1, MGBLX1, MGBLH1, MGBT1, GLC-SX-MMD, GLC-LH-SMD, GLC-BX-U, GLC-BX-D, and GLC-TE (modules sold separately). 10G SFP+ modules are not supported — for 10G uplinks, see the CBS220-24T-4X model.
• What does "Cisco Refresh" mean for this unit?
  Cisco Refresh products are Cisco-certified remanufactured units sold through Cisco's official refurbishment program. They retain genuine Cisco firmware, original Cisco serial numbers, and are tested by Cisco to original factory specifications.
