Cisco Catalyst C1000-24T-4G-L Full English Product Description
1. Product Overview
The Cisco Catalyst C1000-24T-4G-L is a fanless enterprise Layer 2 managed Gigabit switch within the Cisco Catalyst 1000 Series, running lightweight Cisco IOS firmwareCisco. This non-PoE rack-mount model features 24×Gigabit RJ45 downlink ports plus four dedicated 1G SFP fiber uplink slots, delivering wire-speed non-blocking switching performance. Designed for medium-density office workgroups, school computer labs, retail chain branches and out-of-wiring-closet deployments, it adopts silent passive heat sink cooling, robust enterprise security suite, complete Layer 2 switching tools and multi-channel local management (Web UI, CLI, Bluetooth). It offers flexible long-distance fiber uplink expansion for PCs, printers, NAS storage and non-powered Wi-Fi access points in noise-sensitive environments without PoE power delivery requirementsCisco.
