Cisco Systems, Inc. WS-C3850-24PW-S 24-port PoE+ network switch

24-port PoE+ managed switch

The Cisco Catalyst 3850 Series WS-C3850-24PW-S is a managed Ethernet switch with 24 primary ports operating at 10/100/1000 Mbps. It delivers full IEEE 802.3at PoE+ power on every port for access points, cameras or IP phones. The Layer 3 feature set supports routing, VLANs, QoS and LACP for traffic segmentation and link aggregation. A 32K MAC address table and jumbo frame support up to 9198 bytes suit enterprise access and aggregation layers.

Thermals noise and power

Redundant fans and field-replaceable power supplies maintain airflow and service continuity during module swaps. The unit runs on AC 120/230 V at 50/60 Hz, drawing only the power required for connected PoE+ devices and switch operation. Fan speed adjusts to internal temperature, keeping acoustic output low in typical office wiring closets. StackWise-480 technology distributes load across stack members, reducing per-unit thermal stress.

Build connectors and mounting

A desktop form factor allows placement on a shelf or bench without rack ears. Twenty-four RJ45 downlinks provide copper connectivity for endpoints, while modular network module slots accept optional fibre or copper uplinks. Stacking cables connect up to nine switches into a single logical unit managed through one IP address. Hot-swap power supply and fan bays enable maintenance without disconnecting live network cables.
