Cisco C9300-NM-4M Catalyst 9300 Series 4-Port Multigigabit RJ45 Network Module - New

The Cisco C9300-NM-4M is a hot-swappable Catalyst 9300 Series network module that adds four multigigabit RJ-45 uplink ports to increase copper uplink capacity without replacing the switch. Each port supports 100M/1G/2.5G/5G/10G operation with auto-negotiation, enabling high-speed connections to distribution switches, servers, Wi-Fi 6/6E aggregation, or high-performance endpoints using existing Cat5e/Cat6/Cat6a cabling where appropriate. The Catalyst 9300 base switch ships without an uplink module, so this FRU lets you complete builds or restore service fast with front-access installation. Because Catalyst 9300 switches use modular uplinks, you can select this module for sites that need multigig copper today and swap to other uplink options later as requirements change. Use C9300-NM-4M for campus access, branch closets, and IDF/MDF upgrades where fiber is limited, while preserving centralized Cisco IOS XE management, security policies, and stacking designs already deployed on the Catalyst 9300 platform. Ideal for refresh projects, spares inventory, and rapid field replacement at scale.
