CHAPTER 4
TROUBLESHOOTING
This chapter provides information concerning the following:
• Using the LANVIEW diagnostic and status monitoring system
• Troubleshooting network and 2E4X-27 operational problems
• Using the RESET button
4.1 USING LANVIEW
The 2E4X-27 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 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.
