Cisco CBS110-24T Business 110 Series 24-Port Gigabit 2 Combo SFP 48Gbps Unmanaged Switch

The Cisco CBS110-24T is a Business 110 Series unmanaged Gigabit switch built for small offices and branch networks that need simple wired connectivity. It provides 24 Gigabit Ethernet RJ-45 ports plus 2 combo Gigabit uplinks, with more ports than the CBS110-16T and no PoE, unlike the CBS110-24PP. Each combo uplink pairs one RJ-45 port with one SFP slot, with one active at a time, for copper or fiber. Switching capacity reaches 48 Gbps at wire speed with a forwarding rate of 35.7 Mpps for 64-byte packets, and the design is nonblocking. A shared 2 Mbit packet buffer, an 8K MAC address table and jumbo frame support up to 9216 bytes handle mixed traffic efficiently. Four hardware queues with 802.1p priority, priority queuing and weighted round robin keep time-sensitive traffic moving. Energy Efficient Ethernet (IEEE 802.3az) on the copper ports, automatic MDI/MDI-X and head-of-line blocking prevention reduce power draw and cabling friction. Loop detection and cable diagnostics help protect the network and speed up troubleshooting. The fanless design runs silently on an internal universal power supply and draws under 18W, with rack-mount support and a Kensington lock slot.
