Cabletron Systems F3 user manual Lanview LEDs

OVERVIEW OF THE FOT-F3

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.
