CHAPTER 1: INTRODUCTION
1-2 FOT-F3 USER’S MANUAL
Chapter 4, Testing and Troubleshooting , contains procedures
for verifying the proper installation of the FOT-F3. It also
describes LANVIEW LEDs and their function.
Appendix A, Specifications , provides the specifications for the
FOT-F3 transceiver.
1.2 CONVENTIONS
The following conventions are used in this manual:
• Note — Calls the reader’s attention to any item of
information that may be of special importance.
• Caution — Contains information essential to avoid damage
to the equipment.
1.3 OVERVIEW OF THE FOT-F3
The FOT-F3 Fiber Optic Transceiver (Fiber Optic Medium
Attachment Unit or FOMAU) (Figure 1-1) is a device that allows
the connection of two Ethernet devices using single mode fiber
optic cable. The FOT-F3 uses the same signaling protocols
specified by FOIRL and is completely IEEE 802.3 compatible at
the AUI interface (the AUI port connects the transceiver to a
device or workstation via an AUI cable).
The FOT-F3 also has the Cabletron Systems LANVIEW
diagnostic system that monitors network activity and can help to
quickly diagnose physical layer problems using its LEDs.
