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.
Caution
Step 2 Disconnect the cables from the pluggable transceiver module.
Step 3 Remove the pluggable transceiver module from the network module.
Step 4 Loosen the captive screws that hold the network module in place until it completely disengages from the
chassis.
The C3850-NM-8-10G module is held secure 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. When removing the screw, a spring pushes the module
out when the screw is completely disengaged. Ensure that you hold the module securely until it is
completely removed.
Note
Step 5 Carefully slide the network module out of the slot.
Step 6 Install a replacement network module or a blank module in the slot.
Step 7 Place the module that you removed in an antistatic bag or other protective environment.

Installing a Cisco Pluggable Transceiver Module
Before you begin
You must have an installed network module to use the transceiver modules. See the switch release notes on
Cisco.com for the list of supported pluggable transceiver modules. Use only supported pluggable transceivers
on the switch. For the latest information about supported transceiver modules, refer to the Cisco Transceiver
Modules Compatibility Information.
For information about installing, removing, cabling, and troubleshooting pluggable transceiver modules, see
the module documentation that shipped with your device.
Observe these precautions:
Class 1 laser product. Statement 1008
Warning
• Do not remove the dust plugs from the pluggable transceiver modules or the rubber caps from the
fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the module ports
and cables from contamination and ambient light.
• Removing and installing a pluggable transceiver module can shorten its useful life. Do not remove and
insert any module more often than is necessary.
• To prevent ESD damage, follow your normal board and component handling procedures when connecting
cables to the switch and other devices.
