Cabletron Systems FOT-F3 - Manual (Page 13)

OVERVIEW OF THE FOT-F3
FOT-F3 USER’S MANUAL 1-5
The SQE test signal is generated after the FOT-F3 has
transmitted a data packet. This signal is generated only between
the FOT-F3 and the device; it is not transmitted onto the
network.
Note: Do not enable the SQE test feature when the FOT-F3 is
attached to a repeater or Ethernet Version 1 equipment.
Otherwise, network problems (excess collisions) will result.
1.3.3 LANVIEW LEDs
The FOT-F3 incorporates Cabletron Systems LANVIEW
diagnostic and monitoring system. LANVIEW is a series of LEDs
incorporated into all Cabletron Systems products. If a problem
arises, troubleshooting of power failures, collisions, cable faults,
or many other problems can be diagnosed rapidly using these
LEDs.
The LANVIEW LEDs are shown in Figure 1-2 followed by a brief
description of each LED.
Note: Chapter 4, Testing and Troubleshooting , provides more
detail about the LANVIEW LEDs and how to interpret them for
troubleshooting.
