The Cisco 3850-NM-8 x 10G is a networking module designed to provide Gigabit Ethernet network connection to the Cisco Catalyst 3850 Series Switches. The module with SFP+ receptacles provides high-speed connectivity for network applications, such as data centre interconnects, high-performance computing clusters and SANs.
The C3850-NM-8 x 10G modules are supported on the 24-port and 48-port multigigabit switches and on the 24-port 10G SFP+ switch model. This module has eight 10 G slots with an SFP+ port in each slot. Each port supports a 1 G or 10 G connection.
The network module is hot-swappable. If you remove a module, replace it with another network module or a blank module. All ports in the C3850-NM-8-10G module default to 10 G and should be configured as TenGigabitEthernet1/1/1 through TenGigabitEthernet1/1/8, even when you are operating them as 1 G using SFP.
The module is supported on the WS-C3850-12X48U, WS-C3850-24XU, WS-C3850-24XS switches. It is held securely in the switch by only one jackscrew. This screw also helps to eject the module from its connector interface. Before the module can be removed completely, the screw must be unscrewed all the way out. The module should be held securely until it is completely removed.
