Cisco Catalyst C1000-48P-4G-L Full English Product Description
1. Product Overview
The Cisco Catalyst C1000-48P-4G-L is a high-density fanless Layer 2 managed Gigabit PoE+ switch from the Cisco Catalyst 1000 Series, running full Cisco IOS firmware. It features 48 PoE+ Gigabit RJ45 downlink ports with a total 370W PoE power budget and four fixed 1G SFP fiber uplink slots. This mid-power PoE model dynamically allocates power to a mix of VoIP phones, low-power Wi-Fi 5/6 access points and entry-level PoE IP cameras, without supporting full 30W output on all ports simultaneously. Equipped with silent passive heat sink cooling, built-in internal universal power supply, complete enterprise Layer 2 feature set, robust security suite and multi-channel local management, it is ideal for medium-to-large small business wiring closets, school campus labs, retail chain headquarters and quiet out-of-wiring-closet PoE deployments requiring multiple independent 1G fiber uplink connections.
