Installing the Hardware
Installing FPHYs
The FDDI (Fiber Distributed Data Interface) line card has modular PHYs supporting multimode
fiber (MMF), single mode fiber (SMF), and unshielded twisted pair (UTP). Installing the FDDI
module is a two-part process: first, install the PHY cards into the line card; then, install the line card
in the SSR.
Preparing the Module
• Before installing the module, you must install at least one of the following FPHYs (purchased
separately): FPHY-01, FPHY-02, or FPHY-09.
• Because FDDI full duplex is not an industry standard, its implementation is based on the Digital
Equipment Corporation (DEC) standard. FDDI full duplex will interoperate with all DEC
products and most Enterasys Networks FDDI products.
Installing the FDDI PHY Cards
Each FDDI line card has two slots available for PHY cards. One FDDI PHY card can be installed
into each available slot. The following procedure describes how to do this. To install a PHY card
into an FDDI line card:
1. Remove the blank coverplates on the front of the line card, if present.
2. Remove the two screws from the standoffs on both sides of the PHY connector on the line card.
3. Hold the PHY card by the edges and position it above the line card.
4. Slide the transceivers into the slot openings.
5. Connect the stacking connector at the back of the PHY to the pins on the line card.
6. Push the PHY card down until the connector is firmly seated on the line card.
7. Tighten the two screws on the top rear of the PHY and the two screws on the faceplate that will
hold the PHY card in place.
8. You are now ready to install the SSR-FDDI-02 line card. Please refer to Installing Line Cards
on page 71 .
