Install and Remove SFP Modules
Remove SFP Modules:
Step 1 Read the “Safety Warnings” section on page 5-2 section, and disconnect the power supply before you
replace any module.
Step 2 Disconnect all cables from the SFP.
Warning Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into
beams or view directly with optical instruments. Statement 1051
Caution The latching mechanism used on many SFPs locks the SFP into place when cables are connected. Do not
pull at the cabling in an attempt to remove the SFP.
Step 3 Disconnect the SFP latch. See Figure 5-57.
Note SFP modules use various latch designs to secure the module in the SFP port. Latch designs are not linked
to SFP model or technology type. For information on the SFP technology type and model, see the label
on the side of the SFP.
