Cisco Catalyst C1000-48FP-4G-L Full English Product Description

1. Product Overview

The Cisco Catalyst C1000-48FP-4G-L is a high-density fanless Layer 2 managed full PoE+ Gigabit switch within the Cisco Catalyst 1000 Series, running Cisco IOS Lite firmware. Distinguished from mid-power C1000-48P-4G-L (370W PoE), this FP full-power model delivers a massive 740W total PoE budget across all 48 RJ45 downlink ports, supporting full 30W IEEE 802.3at power output on every port simultaneously without power rationing. It is equipped with four dedicated 1G SFP fiber uplink slots for long-distance inter-switch aggregation. Featuring silent passive heat sink cooling, deep full-width 1RU rack chassis, integrated internal universal power supply, complete enterprise Layer 2 switching toolkit, intelligent PoE control and multi-channel local management, it serves as premium high-density PoE access hardware for large retail malls, campus-wide surveillance, medium enterprise branch wiring closets and noise-restricted out-of-closet deployments requiring full PoE+ power for every connected camera and Wi-Fi AP.
