Cisco Business 110 CBS110-5T-D-NA 5-Port Gigabit Unmanaged Switch – Fanless Desktop Design

Business-class Cisco reliability in a plug-and-play switch.

The Cisco CBS110-5T-D is a 5-port Gigabit unmanaged switch from the Cisco Business 110 Series. It is built for small offices, home offices, shops and classrooms that need dependable, silent wired connections for computers, printers and NAS devices without any configuration work.

Why Low-Cost Consumer Switches Cause Problems in Small Offices

Consumer switches are inexpensive, but they often lack basic safeguards. A cable accidentally plugged back into the same switch can create a loop that slows or stops the whole network, and when a connection fails, there is no way to tell whether the cable or the device is at fault.

The CBS110-5T-D keeps the simplicity of an unmanaged switch while adding business-grade protection: loop detection stops broadcast storms caused by miswired cables, and cable diagnostics help pinpoint faulty runs. QoS with 802.1p priority and four hardware queues gives voice and video traffic precedence.

Its non-blocking 10 Gbps switching capacity and support for 9,216-byte jumbo frames keep file transfers to NAS devices and servers running at full Gigabit speed.

Plug-and-Play Gigabit Connectivity

Connect power and Ethernet cables and the switch starts forwarding traffic immediately. All 5 ports auto-negotiate speed and duplex, and auto MDI/MDI-X means any standard cable works.

Silent, Energy-Efficient Design

The switch is fanless, so it runs silently on a desk or shelf. Energy Efficient Ethernet reduces power on idle ports, and the compact chassis uses an external power adapter.

How to Set Up the Cisco CBS110-5T-D

1. Place the switch on a desk or shelf with space around the vents.
2. Connect the external power adapter and confirm the power LED is on.
3. Connect one port to your router or main switch, then connect your computers, printers and other devices to the remaining ports.
4. Check the port LEDs for link and speed; if a loop is detected, remove the duplicate cable connection.
