4.1 USING LANVIEW
The 6H12X-08 uses Cabletron Systems built-in visual diagnostic and
status monitoring system called LANVIEW. The LANVIEW LEDs

diagnosing of network problems. Refer to Table 4-1 for a description of
the LEDs.
For a functional description of the LANVIEW LED on the optional Fast
Ethernet Interface Module (FE-100TX), refer to Section 4.2.
