Chapter 2 Switch Installation Installing SFP and SFP+ Modules Installing an SFP Module Observe these general precautions: Warning Class 1 laser product. Statement 1008 • Do not remove the dust plugs from the SFP modules or the rubber caps from the fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the module ports and cables from contamination and ambient light. • Removing and installing an SFP module can shorten its useful life. Do not remove and insert any SFP module more often than necessary. • To prevent ESD damage, follow your normal board and component handling procedures when connecting cables to the switch and other devices. Caution To avoid damage to the network module, first install the network module in the switch before installing the SFP modules. See the "Installing a Network Module in the Switch" section on page 2-22. Step 1 Step 2 Step 3 Step 4 Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface. Find the send (TX) and receive (RX) markings that identify the top side of the SFP module. On some SFP modules, the send and receive (TX and RX) markings might be replaced by arrows that show the direction of the connection, either send or receive (TX or RX). If the SFP module has a bale-clasp latch, move it to the open, unlocked position. Align the module in front of the slot opening, and push until you feel the connector snap into place.
