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

4.1USING 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 4-1for 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.

NOTE

The terms Flashing, Blinking, and Solid used in the following table indicate the following:

Flashing indicates an irregular LED pulse.

Blinking indicates a steady LED pulse.

Solid indicates a steady LED light. No pulsing.
