Cisco Business CBS110-24T-NA - 24-Port Gigabit Unmanaged Switch, 2x Gigabit SFP Combo, Fanless, Rack-Mount - Refresh

The Cisco Business CBS110-24T-NA is a 24-port Gigabit Ethernet unmanaged switch with 2 SFP combo uplinks built for small business, branch office, workgroup, and growing SMB networks. It delivers 24 10/100/1000 RJ-45 ports plus 2 Gigabit SFP combo slots — for 48 Gbps switching capacity and a 35.7 mpps forwarding rate — in a fanless, rack-mountable 1U chassis. True plug-and-play: no software, no configuration, no IT skills required. Cisco Refresh certified-remanufactured units offer genuine Cisco hardware at significant savings versus new pricing.

Cisco Business CBS110-24T-NA - Key Features & Benefits

• 24-Port Gigabit Connectivity for SMB Networks: 24x 10/100/1000 RJ-45 ports plus 2x Gigabit SFP combo uplinks deliver line-rate connectivity for PCs, IP phones, printers, NAS, access points, and servers across small offices, workgroups, and branch deployments
• Cisco-Rated Switching Performance: 48 Gbps switching capacity and 35.7 mpps maximum forwarding rate at 64-byte packets (Cisco Business 110 datasheet, nonblocking architecture) handle bandwidth-intensive cloud apps, large file transfers, and video traffic; 8K MAC address table and 9216-byte jumbo frame support
• Plug-and-Play — No Configuration Required: Truly unmanaged operation — connect cables and the switch runs. Each port auto-negotiates speed and duplex, with auto MDI/MDI-X so straight-through or crossover cables both work
• 2 Gigabit SFP Combo Uplinks for Fiber Expansion: Two SFP slots accept Cisco-supported modules per the Business 110 datasheet: 1000BASE-SX (MGBSX1, multimode 500m), 1000BASE-LX (MGBLX1, single-mode 10km), 1000BASE-LH (MGBLH1, single-mode 40km), and 1000BASE-T (MGBT1, UTP 100m). Each SFP shares its interface with one of the 24 RJ-45 ports — using an SFP automatically disables the paired copper port, so the switch supports 24 active Ethernet interfaces at one time
• IEEE 802.1p QoS for Voice and Video Prioritization: Hardware-level 802.1p priority handling lets the switch prioritize delay-sensitive voice and video traffic based on the priority bits in incoming packets — an automatic, non-configurable behavior consistent with the device's unmanaged design
• Fanless, Silent, Rack-Mountable Design: 1U rack-mount chassis (279 x 170 x 44 mm / 11 x 6.7 x 1.73 in) with fanless design for silent operation in offices, conference rooms, and quiet IT closets; Kensington lock slot for physical security
• Energy Efficient Ethernet for Lower Power Bills: IEEE 802.3az EEE support on all copper ports puts idle links into low-power sleep, reducing power draw — worst-case consumption only 17.79W at 110V with internal universal 100–240V PSU

Cisco Business CBS110-24T-NA - Frequently Asked Questions (FAQ)

• What does "Cisco Refresh" mean?
  Cisco Refresh is Cisco's official certified-remanufactured program. Units are genuine Cisco hardware that has been inspected, tested, and refurbished to Cisco's specifications — sold at a lower price point than brand-new equivalents.
• Does this switch support PoE?
  No. The CBS110-24T-NA is a data-only switch with no PoE on any port. If you need PoE to power IP phones, wireless APs, or cameras, the CBS110-24PP-NA is the PoE-equipped equivalent in the same series (12 PoE ports, 100W budget).
• How do the 2 SFP combo ports actually work?
  Each of the 2 SFP slots is paired with one of the 24 RJ-45 ports. Inserting an SFP transceiver automatically disables the paired copper port — only one media type is active per combo pair at any time. The switch therefore supports 24 active Ethernet interfaces at one time; the 2 SFP combo slots give you the choice of copper or fiber uplinks without adding to the total active interface count.
