TROUBLESHOOTING
This chapter provides information concerning the following:
• Using LANVIEW diagnostic and status monitoring system
(
Section 4.1 )
• The FE-100TX LED ( Section 4.2 )
• Troubleshooting checklist for network and device operational
problems (
Section 4.3 )
• Using the RESET button ( Section 4.4 )
4.1 USING LANVIEW
The 2H23-50R and 2H33-37R use Cabletron Systems built-in visual
diagnostic and status monitoring system called LANVIEW. The
LANVIEW LEDs, shown in
Figure 4-1 and Figure 4-2 , 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) that can be installed in a
2H23-50R, refer to
Section 4.2 .
For a functional description of the LANVIEW LED on an optional HSIM
installed in a 2H33-37R, refer to the user’s guide for that HSIM.
