50-Port Gigabit Smart Plus Switch

The Cisco SG220-50-K9-NA is a Layer 2 managed switch built for small to mid-sized business networks. It provides 48 RJ45 ports operating at 10/100/1000 Mbps and two SFP uplink slots for fibre connectivity. The unit is rack-mountable and wall-mountable, with a supplied rack-mount kit and rubber feet.

Suited for managed access-layer deployments

This switch suits administrators who need VLAN, QoS and basic security features without the complexity of a full Layer 3 core. It is not for environments that require routing between VLANs, stacking, or PoE power for phones and cameras. Buyers needing Layer 3 services or powered ports should look elsewhere.

48 RJ45 ports plus two SFP uplinks

The port count and uplink format are the decisive specification: 48 copper ports at Gigabit speed and two SFP cages for fibre uplinks. If the network design calls for more copper density, 10 Gigabit uplinks, or Power over Ethernet, this model does not meet that requirement.

Questions about this item

What uplink interface does the SG220-50-K9-NA provide and what speed does it cap at?

The switch includes two SFP uplink ports; speed is determined by the SFP module installed, while the 48 RJ45 ports auto-negotiate up to 1000 Mbps.

What physical space and mounting hardware does the 1.73" x 17.32" x 7.91" chassis need?

The unit is rack-mountable and wall-mountable; the package supplies a rack-mount kit and rubber feet for either installation.

How is the switch initially configured and which step is often missed?

Connect the supplied console cable to a terminal, run the setup wizard for IP and VLAN settings, then save the running configuration so changes persist after reboot.
