Product Overview
The Cisco C9300-NM-4M is a modular uplink network module with 4 multigigabit (mGig) ports, designed for Cisco Catalyst 9300 Series switches. It provides multi-speed Ethernet uplinks (100M/1G/2.5G/5G/10G) using RJ-45 copper interfaces, offering flexibility for high-speed access or aggregation networks using existing cabling.
Product Description
The Cisco C9300-NM-4M module offers 4 multigigabit RJ-45 ports that support auto-negotiated speeds ranging from 100 Mbps up to 10 Gbps, depending on the connected device and cable quality. It is ideal for Wi-Fi 6/6E/7 deployments, high-performance workstations, and IoT aggregation, where higher-than-Gigabit speeds are required over Cat5e/Cat6 cabling. As a hot-swappable module, it provides plug-and-play flexibility for upgrading switch uplinks or horizontal links without service interruption. Fully compatible with select Catalyst 9300 switch models, this module is an excellent choice for cost-effective bandwidth scaling in enterprise networks.
