Figure 8: Installing the Network Module in the Switch
Unlike other network modules, the C3850-NM-8-10G cannot be fully inserted and secured until the
jackscrew is properly tightened.
Note
1
Push the module into the uplink slot until the jackscrew connects with the rightmost tab.
2
You will feel some light resistance, because a spring-loaded tab inside the slot will push back
against the C3850-NM-8-10G module
3
Continue to tighten the jackscrew while gently pushing the front panel of the network module
into the slot.
Network Module Port Configurations
C3850-NM-4-1G Module
All ports in the C3850-NM-4-1G module are natively GigabitEthernet and are configured GigabitEthernet1/1/1
though GigabitEthernet1/1/4. There are only four interfaces that are valid, and the other four should not be
used even though they still show up in the CLI.
