Unmanaged L2 Gigabit Ethernet Switch Cisco CBS110 — 5x RJ-45 10/100/1000, 1U, 12V DC, 2048 MAC, 10 Gbit/s

The Cisco CBS110 is an unmanaged Layer 2 Gigabit Ethernet switch that provides five RJ-45 10/100/1000 ports in a compact 1U rack-mountable form factor. Designed for basic network connectivity in small offices and rack-mounted deployments, it supports full-duplex operation and a MAC address table capacity of 2048 entries. The switch complies with common Ethernet standards such as IEEE 802.1p for priority, and IEEE 802.3 family standards for media and flow control, offering a switching capacity of 10 Gbit/s and a 12 V DC power input for straightforward installations.

Advantages

The Cisco CBS110 delivers simple plug-and-play installation without management overhead, allowing quick integration into existing network environments. Its five Gigabit RJ-45 ports provide high-speed wired connectivity for devices requiring reliable Ethernet links. Standards compliance (including IEEE 802.1p and IEEE 802.3 variants) enables interoperable operation with a wide range of network equipment, while a 2048-entry MAC table and 10 Gbit/s switching capacity support modestly sized LANs and basic traffic loads. The 1U rack form factor and 12 V DC input make it adaptable to rack-mounted small office setups and constrained power environments.

Suitable for (tasks / use cases)

• Small office networks requiring reliable wired Gigabit connectivity
• Rack-mounted deployments in branch offices or network cabinets
• Connecting workstations, printers and NAS devices in compact environments
• Basic network segmentation with QoS-prioritized traffic at layer 2

How to use

Install the Cisco CBS110 in a rack or on a flat surface using the provided mounting options. Connect power using a compatible 12 V DC adapter and verify power and link LEDs. Plug Ethernet cables into the RJ-45 Gigabit ports to connect computers, printers, IP phones or other network devices. The switch operates as an unmanaged device, so no configuration is required; connected devices obtain connectivity through the switch automatically and can communicate at full-duplex Gigabit speeds where supported.

Recommendations

Place the switch in a ventilated rack space free of excessive heat and dust. Use quality Cat5e/Cat6 cables to ensure consistent Gigabit performance. For environments with mixed traffic, rely on the switch's IEEE 802.1p priority support to improve handling of latency-sensitive data. Regularly verify link status LEDs and perform cable diagnostics when connectivity issues occur.
