SFP Module Damage
The optical port plug protects the sensitive optical fibers against dirt and damage.
Dirt and damage can render the SFP module inoperable.
Only remove the optical plug when you are ready to connect a cable to the SFP
module. When no cable is connected, cover the port with an optical port plug.
