EVESKY C9400-LC-48U 9400 Series Line Card switch module 48 ports 10/100/1000 UPOE 60 W

Cisco Catalyst 9400 Line Card

The EVESKY C9400-LC-48U is a plug-in line card that adds forty-eight 10/100/1000 ports to a Cisco Catalyst 9400 chassis. It targets network teams expanding wired access for security, IoT and cloud workloads in enterprise environments.

Sustained load behaviour

Each port delivers up to 60 W under the IEEE 802.3bt UPOE standard, maintaining that power budget across all forty-eight ports simultaneously. The module supports the chassis architecture rated for 9 Tbps of system bandwidth, keeping throughput consistent during prolonged high-density traffic.

Thermals, noise and power

The line card measures 1.6 by 14.92 by 14.57 inches and draws power directly from the host chassis, adding no separate fan or power supply. Thermal management and acoustic output are therefore governed by the chassis cooling design rather than the module itself.
