Description:

The Cisco C9300-NM-2-40G Network Module is used in Cisco Catalyst 9300 Series switches to provide high-speed 40 Gigabit Ethernet uplink connectivity for enterprise campus and data network infrastructures. It adds two 40 Gigabit Ethernet QSFP+ uplink interfaces designed to support high-bandwidth aggregation and backbone connections within enterprise switching environments. Commonly installed in Cisco Catalyst 9300 switches deployed in campus core networks, aggregation layers, and enterprise network closets where high-speed uplink capacity and scalable switching performance are required. Network administrators and system integrators use this module for network upgrades, backbone connectivity expansion, replacement of existing uplink modules, and deployment of high-capacity enterprise network links.

Applications:

The Cisco C9300-NM-2-40G module is used in enterprise and campus networking environments where high-speed uplink connectivity between access switches and core network infrastructure is required. It is commonly deployed in corporate campuses, large office networks, educational institutions, and data center edge environments to provide high-bandwidth connections between switching layers. The module enables efficient traffic aggregation, faster data transmission, and scalable network performance for growing enterprise network demands.
