4.3 USING LANVIEW
LANVIEW is Cabletron Systems’ built-in visual diagnostic and status
monitoring system. Using LANVIEW, your network troubleshooting
personnel can quickly scan the LANVIEW LEDs to observe network
status or diagnose network problems, and determine which node or
segment is faulty. Figure 4-2 shows the locations for each of the front
panel LANVIEW LEDs.
Figure 4-2 LANVIEW LEDs
PWR (Green)
When this LED is lit, it indicates that the MRXI is receiving power. If
this LED is not lit, it indicates a loss of input power. Check the input
power source (circuit breaker, fuse, etc.). If the proper power source is
present, the problem could be with the MRXI.
RCV (Yellow)
When this LED flashes, it indicate that the MRXI is repeating data
packets received from the associated Network Port segment. The flash
of the LED is pulse stretched for viewing effect.
