Note We strongly recommend cleaning optical fiber connections before attaching cables to equipment. See the “Cleaning the Fiber-Optic Connections” section on page 5-14for information.

Step 1 Check to be sure that either the SFP optical port or the RJ-45 port is used on ports 0/0 and 0/1. Only one of the pair can be chosen.

Step 2 Remove the plug from the SFP module so that you can insert the cables. Keep the plug for use should you ever disconnect the optical fiber cables.

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

Step 3 Attach the appropriate optical fiber cable directly to the SFP module. You can use either simplex or duplex connectors for most devices. (Figure 2-16shows an SFP module with a duplex connector being installed in SFP port 0/1.)

•For simplex connectors, two cables are required, one cable for transmit (TX) and a second cable for receive (RX).

•For duplex connectors, only one cable that has both TX and RX connectors is required.
