Cisco Business 220 48-port PoE+ switch

This managed switch delivers 48 Gigabit RJ45 ports and four SFP uplinks with a 382W PoE+ budget. It suits small businesses that need reliable wired connectivity and centralized power for access points, cameras or phones. The fanless design allows quiet deployment in open offices, retail spaces or classrooms. Management is handled through an intuitive on-box UI, mobile app and Cisco Business Dashboard.

Best for PoE-heavy edge deployments.

The switch fits networks that require PoE+ on every port and simple cloud-managed operation. It does not meet the needs of organisations that require Layer 3 routing, higher uplink speeds or advanced multicast features. Buyers who need 10G uplinks, stacking or redundant power supplies should evaluate other platforms.

382W PoE+ budget across 48 ports

The total power budget of 382W determines how many Class 4 devices can run simultaneously. Calculate the per-port draw of your endpoints to confirm the budget covers your deployment. Exceeding the limit will cause ports to disable or devices to underperform.

Questions about this item

What type of SFP modules do the four uplink ports accept?

The four uplink ports accept 1G SFP modules for fibre or copper uplinks.

Will the 382W PoE budget still power my older 10/100 IP phones and cameras?

Yes, the 48 PoE+ ports negotiate IEEE 802.3af or 802.3at per device, so legacy 10/100 endpoints draw only the power they need within the 382W total.

Which LED pattern shows the switch has booted and all 48 copper links are up at 1G?

After boot the system LED turns solid green and each of the 48 RJ-45 port LEDs shows solid green for a 1000 Mbps link.
