16-port managed desktop switch

The CBS250-16T-2G-NA is a managed network switch built for small business or branch-office deployments that need Layer 2 control without a rack. Sixteen copper ports and two SFP uplinks give enough density for workstations, access points and a server link in one compact unit.

Build and connectivity

A fanless desktop chassis keeps the switch silent in open-plan offices or reception areas. Front-panel LEDs show system health, link activity and port speed at a glance, while a recessed reset button allows quick recovery without tools. UTP Category 5e or better cabling supports the 10/100/1000Mbps ports and the 9000-byte jumbo frames pass large data payloads efficiently.

Upgrade path

The 8K MAC address table and 1.5 MB buffer replace unmanaged switches that drop frames under bursty loads or lack VLAN and QoS features. Managed functions such as port mirroring and link aggregation become available without moving to a rackmount platform. The jump is worth it when traffic segmentation or deterministic latency matter more than basic connectivity.

Questions about this item

What speed does the 10/100/1000Mbps RJ45 interface actually cap at in practice?

Each of the 16 RJ45 ports negotiates up to 1000Mbps full-duplex using Category 5e or better UTP cabling, so the practical ceiling is 1 Gbps per port.

What physical space and mounting does the 10.56" x 10.69" x 1.73" desktop chassis require?

The unit needs a flat surface at least 10.56 inches deep by 10.69 inches wide with 1.73 inches of vertical clearance; it weighs 3.92 lbs and has no rack ears included.

How is the switch initially configured, and which step do installers most often miss?

Connect power, link a PC to any RJ45 port, browse to the default IP address, then run the web-based setup wizard — the step most often missed is saving the running configuration so changes survive a reboot.
