CHAPTER 4

TROUBLESHOOTING

This chapter provides information concerning the following:

•Using the LANVIEW diagnostic and status monitoring system

•Troubleshooting network and module operational problems

•Using the RESET button

The four interface modules covered in this manual all share the same LANVIEW LEDs.

4.1USING LANVIEW

The DLE2X-MA and DLE3X-MA use a 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 (DELTX-UI), 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.

The terms flashing, blinking, and solid used in the LED definition tables of this chapter indicate the following:

Flashing indicates an irregular LED pulse.

Blinking indicates a steady LED pulse.

Solid indicates a steady LED light. No pulsing.
