4.1 USING LANVIEW
The 2E4X-27R uses the Cabletron Systems built-in visual diagnostic and
status monitoring system called LANVIEW. The LANVIEW LEDs
(
Figure 4-1 ) allow quick observation of the network status to aid in
diagnosing 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 .
All LEDs for the High Speed Interface Module (HSIM) are located on the
HSIM and are described in the associated HSIM user’s guide.
