The FR-3000 allows users to easily connect two Ethernet cable or link segments, separated by up to 3 km, using fiber optic cable. This repeater fully conforms to IEEE 802.3 FOIRL specifications and provides the flexibility to connect networks using Ethernet Version 1, Version 2, and/or IEEE 802.3 equipment.
- Page 7 FR-3000s using an attachment unit interface (AUI) cable, up to 50 meters long. The link be- tween the two FR-3000s is made by attaching the fiber optic cable to the fiber optic ports on each FR-3000. The repeater will transmit re-timed data packets, regenerate preambles, extend collision fragments, au- tomatically partition problem segments, and automatically reconnect non-problem segments.

Page 16: Testing And Troubleshooting
TESTING AND TROUBLESHOOTING This chapter lists procedures to test the FR-3000 Fiber Optic Repeater after it has been con- nected to the network. A description of LANVIEW and its function in troubleshooting physical layer network problems is also given. 4.1 INSTALLATION CHECK-OUT This section contains procedures to test the FR-3000 Fiber Optic Repeater after it has been installed to ensure that the physical layer of the network is operating properly. - Page 17 3000. Refer to Figure 4-2. Power (PWR) LED When lit, this LED indicates that the FR-3000 is receiving power. If this LED is not lit, the problem may be with the input power, or in the FR-3000. Transceiver Power (XCVR PWR) LED When lit, this LED indicates that the FR-3000 is providing power to the external transceiver connected to the FR-3000.
