Troubleshooting

This chapter explains how to isolate and diagnose problems with the

BayStack 350 switch.

This chapter includes the following information:

•LED indications

•Diagnosing and correcting the problem

•Port connection problems

This chapter is organized to help lead you through a logical process for troubleshooting the BayStack 350 switch. For example, because the LEDs provide visual indications of problems, the section “ LED Indications” on page 4-2 helps you to understand the various states that each LED can exhibit during operation.

Note: The LED Display panel configuration for your switch may be different than shown in Figure 4-1, depending on the date of manufacturing (see the note in “10BASE-T/100BASE-TX Port Connectors” on page 1-3).

If you need more help in determining the problem, the section “ Diagnosing and Correcting the Problem” on page 4-4 provides a table that lists symptoms and corrective actions you can perform to resolve specific problems.

Subsequent sections provide step-by-step procedures for correcting the problems listed in the table.
