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 SFP modules, insert the RJ-45 cable connector into the SFP module. Note When you connect to 1000BASE-T SFP modules, be sure to use a twisted four-pair, Category 5 or later cable. Removing SFP Modules from SFP Module Slots To remove an SFP module from a module slot, 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. Tip For reattachment, note which cable connector plug is send (TX) and which is receive (RX). 2-34 Catalyst 3750 Switch Hardware Installation Guide OL-6336-10
