Chapter 2 Installation Installing and Removing SFP Modules Figure 2-31 Installing an SFP Module into an SFP Module Slot 19 20 21 22 23 24 Catalyst 2950 LRE SERIES 1 2 1 2 81564 Step 5 For fiber-optic SFP modules, remove the dust plugs from the SFP module optical ports and store them for later use. Caution Do not remove the dust plugs from the 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 connecting to 1000BASE-T SFP modules, be sure to use a twisted four-pair, Category 5 cable. Removing SFP Modules from SFP Module Slots 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 LC from the SFP module. Tip For reattachment, note which cable connector plug is send (TX) and which is receive (RX). Step 3 Step 4 For fiber-optic SFP modules, insert a dust plug into the optical ports of the SFP module to keep the optical interfaces clean. Unlock and remove the SFP module, as shown in Figure 2-32, Figure 2-33, and Figure 2-34. • If the module has a Mylar tab latch, pull the tab straight out so that you remove the SFP module from the port in a parallel direction. Do not twist or pull the tab because you could disconnect it from the SFP module. OL-6156-01 Catalyst 2950 Switch Hardware Installation Guide 2-25
