INSTALLING THE FOT-F3 This chapter contains instructions for unpacking your Cabletron Systems’ FOT-F3 Transceiver, connecting the FOT-F3 to an Ethernet device and the network, installing cable supports, and mounting the transceiver (if necessary). Verify that all requirements listed in Chapter 2, Installation Requirements/Specifications, are met before installing the transceiver. -
Page 24: Connecting Fot-F3 To The Network
Chapter 2, Installation Requirements/ Specifications, complete the installation instructions listed in this section. NOTE: Ensure that the site where the FOT-F3 will be located will allow the AUI cable and the fiber optic link segment to be easily connected to the transceiver before you begin the installation procedures. - Page 25 NOTE: The SQE test function must be disabled if you are connecting the transceiver to Ethernet Version 1 equipment or to a repeater. Set the SQE Switch as follows: • To disable the SQE test function, set the switch (Fig. 3-1) towards the optical ports to the off (o) setting.

1 MHz idle signal when it is not transmitting data. Collision (CLN) LED This red LED flashes to indicate that the FOT-F3 is detecting a collision condition. The frequency of flashes increases as the network activity increases since more collisions are likely to occur. - Page 40 The flash of the LED is pulse stretched for viewing effect. The LED will flash when traffic is on the network, even if the data is not intended for the device attached to the FOT-F3. TESTING AND TROUBLESHOOTING 1300nm Page 4 - 7...
- Page 41 SQE test is not enabled. The SQE test is used to ensure that the collision presence circuit and path are operational between the FOT-F3 and the Ethernet device attached to the AUI port.
