CHAPTER 4
TROUBLESHOOTING
This chapter provides information concerning the following:
• Using LANVIEW (Section 4.1)
• FE-100TX LED (Section 4.2)
• Troubleshooting Checklist (Section 4.3)
• Using the RESET Button (Section 4.4)
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.
