Troubleshooting

This chapter provides information concerning the following:

•Using the LANVIEW diagnostic and status monitoring system (Section 4.1)

•Troubleshooting network and module operational problems (Section 4.2)

•Using the RESET button (Section 4.3)

4.1USING LANVIEW

The SmartSwitch modules use 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 4-1for a description of the LEDs.

Refer to the HSIM or VHSIM User’s Guide for a description of the HSIM or VHSIM LEDs.

NOTE

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, (approximately 50% on, 50% off). Solid indicates a steady LED light. No pulsing.
