Catalyst 9400 Series 48‑Port UPOE+ Line Card

Product Description

The Cisco C9400‑LC‑48H is a high‑density line card designed for modular Cisco Catalyst 9400 Series switches, providing 48 Gigabit Ethernet RJ‑45 ports with Universal Power Over Ethernet Plus (UPOE+) support. This module expands the Catalyst 9400 chassis platform with fiber access and power delivery capabilities that are ideal for enterprise, campus, and digital‑building deployments. The card delivers robust connectivity for high‑power endpoints such as wireless access points, surveillance systems, VoIP phones, and IoT devices.

Each port supports PoE standards including IEEE 802.3bt (UPOE+ up to ~90 W), IEEE 802.3at (PoE+), and IEEE 802.3af (PoE), enabling flexible power delivery to a wide range of devices directly over the network cable from the chassis backplane.
