Cisco Systems, Inc. C9300-NM-4G Network Module

The Cisco C9300-NM-4G Network Module provides four 1-Gigabit SFP uplink ports for scalable fiber connectivity in Cisco Catalyst 9300 switches. As a modular uplink module for the Catalyst 9300 Series, it delivers up to 1 Gbps per port and enables flexible uplink paths between access, distribution, and core layers in enterprise campus networks. It requires Cisco-compatible SFP fiber transceivers and is designed to install in compatible Catalyst 9300 switches to extend uplink capacity for enterprise and industrial networking environments. Typical applications include upgrades, infrastructure expansion, retrofits, or replacement of existing uplink modules to improve bandwidth and network performance. Common replacements and compatibility options include the C9300-NM-8X, C9300-NM-2Q, and the C3850-NM-4-1G, helping network teams match modules across Cisco switches.
