Installing SFP Modules Chapter 5 Installing and Upgrading Internal Modules and FRUs Removing SFP Modules Follow these steps to remove an SFP from a Cisco 2900 series or Cisco 3900 series router: Step 1 Step 2 Read the "Safety Warnings" section on page 5-2 section and disconnect the power supply before you perform any module replacement. 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 on the cabling in an attempt to remove the SFP. Step 3 Disconnect the SFP latch. See Figure 5-46. 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.
