CHAPTER 4
TROUBLESHOOTING
This chapter provides information concerning the following:
• Using the LANVIEW diagnostic and status monitoring system
• Troubleshooting network and 2H22-08R operational problems
• Using the RESET button
4.1 USING LANVIEW
The 2H22-08R uses 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 the
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.
