Step 3 When all your network connections are complete, proceed to the section "Connecting to an Optical Bypass Switch" later in this chapter. Single-Attachment FDDI Connections Step 1 Using a multimode fiber-optic cable, connect the single-attachment module's PHY-S port through a concentrator to a single-attachment ring, or connect it point-to-point directly to another device. (See Figure 3-11.)
