Installing a Network Module in the Switch
Step 3 Remove the 10-Gigabit Ethernet module slot EMC plug, and save it.
Caution Verify the correct orientation of your module before installing it. Incorrect installation can damage the
module.
Caution Do not install the network module with connected cables or installed SFP modules. Always remove any
cables and modules before you install the network module.
Caution 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.
Step 4 Position the module face up to install it in the module slot. Slide the module into the slot until the back
of the module faceplate is flush with the switch faceplate. Fasten the captive screws to secure the
network module in place.
