Cisco Systems, Inc. CBS220-48P-4X-NA 48-port PoE network switch with 4×10G SFP+

48-port PoE switch for small-business networks

The Cisco Business 220 Series switch provides 48 Gigabit RJ45 ports and four 10G SFP+ uplinks. All copper ports deliver PoE or PoE+ power, supporting devices such as access points, IP phones and cameras without separate injectors. Managed Layer 2 features include VLAN, QoS and ACLs for traffic segmentation and security. The fanless design suits open-plan offices, retail spaces and classrooms where silent operation matters.

382 W total PoE budget

The switch allocates up to 382 watts across its 48 PoE ports, letting you power a full complement of Class 3 or Class 4 endpoints simultaneously. Each port negotiates 802.3af or 802.3at automatically, so mixed device types share the budget without manual configuration. Monitoring via the on-box UI, mobile app or Cisco Business Dashboard shows real-time draw per port, preventing overload before it affects uptime.

Fanless cooling with Energy Efficient Ethernet

IEEE 802.3az compliance reduces power draw during low-traffic periods, lowering operational cost. The fanless chassis dissipates heat passively, eliminating moving-part noise and mechanical failure risk in dust-prone environments. Typical power consumption scales with port utilisation and PoE load rather than running at a fixed maximum. This thermal profile suits deployments outside traditional wiring closets.
