Cisco C9300-NM-4M Catalyst 9300 Network Module

Brand:
Cisco

The Cisco C9300-NM-4M is a high-performance network expansion module designed for Cisco Catalyst 9300 Series switches. Featuring 4 × Multigigabit (mGig) RJ45 Ethernet ports supporting speeds from 100 Mbps up to 10 Gigabit Ethernet, this hot-swappable plug-in module delivers flexible copper uplink connectivity, high-speed access aggregation, and scalable enterprise network expansion for modern campus and branch deployments.

OVERVIEW

  • The Cisco C9300-NM-4M is part of the Cisco Catalyst 9300 Series modular uplink ecosystem, providing four Multigigabit Ethernet interfaces that support multiple speeds over standard copper cabling. Designed as a field-replaceable and hot-swappable network module, it allows organizations to expand switch connectivity without replacing existing infrastructure, offering long-term investment protection and deployment flexibility.
  • Unlike SFP-based uplink modules, the C9300-NM-4M uses RJ45 copper interfaces and supports Multigigabit speeds including 100 Mbps, 1 Gbps, 2.5 Gbps, 5 Gbps, and 10 Gbps. This makes it ideal for connecting high-performance wireless access points, aggregation switches, servers, and bandwidth-intensive enterprise devices while utilizing existing structured cabling.
