A module interface might become error-disabled when a network module with connected fiber-optic
cables is installed or removed. If an interface is error-disabled, you can reenable the interface by
using the shutdown and no shutdown interface configuration commands.
Unlike other network modules, the C3850-NM-8-10G cannot be fully inserted and secured until the
jackscrew is properly tightened.
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.
