Cisco 3850 Four-Port 10G Ethernet Network Module, C3850-NM-4-10G, Refurbished, Original

C3850-NM-4-10G | Cisco 10G Ethernet Network Module | 3850 | 4 Port

C3850-NM-4-10G is a network expansion module designed to provide stacking capabilities utilizing the organization’s current cabling infrastructure. The module is a plug-in module that is easy to install and configure. It connects to the switch using a high-speed stacking cable and can be used in either standalone or stackable mode.

This module has four 10 G slots or four 1 G slots. All ports in the C3850-NM-4-10G module default to 10 G and should be configured as TenGigabitEthernet1/1/1 through TenGigabitEthernet1/1/4, even when you are operating them as 1 G using SFPs, thereby increasing the network capacity and throughput of the switch. Only four interfaces are valid; the other four should not be used even though they still show up in the CLI.

The network module is hot-swappable. If you remove a module, replace it with another network module or a blank module. The module is supported only on the 48-port Gigabit Ethernet models or on the 12-port or higher 10 Gigabit Ethernet models.

The module comes with the Integrated wireless controller capability that allows the module to function as a wireless controller for wireless access points (WAPs).
