INTRODUCTION
An AUI cable, up to 50 meters long, is used to connect an
Ethernet device to the AUI port on the transceiver. The
AUI cable must meet specifications for either IEEE 802.3
or Ethernet Version 1 or Version 2.
Signal Quality Error (SQE) Test
The FOT-F3 has a Signal Quality Error (SQE) Test Enable
Switch that allows you to enable or disable the SQE
(“heartbeat”) test function. The SQE test allows the
transceiver to generate a signal to ensure that the collision
circuit and path are operational between the FOT-F3 and
the Ethernet device attached to the transceiver’s AUI port.
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 will not be
transmitted onto the network. The SQE Test must not be
used when the FOT-F3 is attached to a repeater or
Ethernet Version 1 equipment.
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 a series of LEDs.
