CHAPTER 4

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)

4.1USING 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 4-1and Figure 4-2, allow quick observation of the network status to aid in diagnosing network problems. Refer to Table 4-1for 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.
