Installing and Removing SFP Modules Chapter 2 Switch Installation Step 5 For fiber-optic SFP modules, remove the dust plugs from the optical ports, and store them for later use. Caution Do not remove the dust plugs from the fiber-optic SFP module port or the rubber caps from the fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the SFP module ports and cables from contamination and ambient light. Step 6 Insert the cable connector into the SFP module: • For fiber-optic SFP modules, insert the LC or MT-RJ cable connector into the SFP module. • For copper 1000BASE-T SFP modules, insert the RJ-45 cable connector into the SFP module. Note When connecting to 1000BASE-T SFP modules, be sure to use a twisted four-pair, Category 5 or higher cable. Removing SFP Modules To remove an SFP module from a module receptacle, follow these steps: Step 1 Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface on the chassis. Step 2 Disconnect the cable from the SFP module, and insert a dust plug into the cable end. Tip For reattachment, note which cable connector plug is send (TX) and which is receive (RX). Step 3 Unlock and remove the SFP module, as shown in Figure 2-14. If the module has a bale-clasp latch, pull the bale out and down to eject the module. If the bale-clasp latch is obstructed and you cannot use your index finger to open it, use a small, flat-blade screwdriver or other long, narrow instrument to open the bale-clasp latch.
