• Do not remove the dust plugs from the fiber-optic SFP modules or the rubber caps from the fiber-optic
cable until you connect the cable. The plugs and caps protect the module ports and cables from
contamination and ambient light.
• Removing and installing a network module can shorten its useful life. Do not remove and insert a network
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.
Procedure
Step 1
Attach an ESD-preventive wrist strap to your wrist and to an earth ground surface.
Step 2
Remove the module from the protective packaging.
Step 3
Remove the blank module from the switch and save it.
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.
Caution
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.
