Removing and Installing SFP Modules
Step 5 Protect your line card by inserting clean SFP module cage covers into the optical module cage when
there is no SFP module installed.
Caution When pulling the tab to remove the SFP module, be sure to pull in a straight outward motion so you
remove the SFP module from the port in a parallel direction. Do not twist or pull the tab, because you
might disconnect it from the SFP module.
