Description:

The Cisco C3850-NM-2-10G network expansion module is used in Cisco Catalyst 3850 Series switches to provide additional 10 Gigabit Ethernet uplink connectivity for enterprise network infrastructure. Commonly installed in corporate network closets, campus environments, and data center aggregation layers where high-speed uplink connections are required between switches and core network devices. Network administrators and system integrators use this module for switch uplink upgrades, network expansion, and replacement of existing expansion modules in Catalyst 3850 switching platforms.

Applications:

The Cisco C3850-NM-2-10G module is commonly deployed in enterprise and campus networks where high-bandwidth uplink connectivity is required between access-layer switches and distribution or core network infrastructure. It is used in corporate offices, universities, healthcare facilities, and data centers to connect switches to aggregation switches, core routers, and high-speed network infrastructure using 10 Gigabit fiber connections.
