Note When installing an SFP or SFP+ module, you should hear a click as the triangular pin on the bottom of the SFP
module snaps into the hole in the receptacle, indicating that the module is correctly seated and secured in the
receptacle. Verify that the SFP modules are completely seated and secured in their assigned receptacles on the
line card by firmly pushing on each SFP module.
