DIAGNOSTIC AND MONITORING SYSTEM
The 7F06-02 Module uses LANVIEW, Cabletron Systems’ built-in visual diagnostic and status monitoring system.
With LANVIEW LEDs the status of each transmit and receive port on the
7F06-02 Module can be determined, at a glance. This section discusses the function and purpose of the LEDs on the 7F06-02 Module.
Figure 4-1 shows the LANVIEW LEDs of the 7F06-02 Module.
