Cisco Catalyst C1000-16T-2G-L Full English Product Description
1. Product Overview
The Cisco Catalyst C1000-16T-2G-L is a fanless Layer 2 managed Gigabit switch from the Cisco Catalyst 1000 Series powered by Cisco IOS firmware. Designed for small offices, retail shops, classroom workgroups and branch secondary access networks, it features 16 non-PoE Gigabit RJ45 downlink ports paired with 2×1G SFP/RJ45 combo uplink ports. With silent passive cooling, compact rack-mount chassis, complete enterprise Layer 2 switching functions, robust security suite and multiple local management options, this switch delivers stable wire-speed data forwarding for PCs, printers, NAS storage and non-powered wireless access points in space-limited, noise-sensitive wiring closets.
