Troubleshooting

Overview

This chapter explains how to isolate and diagnose problems with your BayStack 350 10/100 Autosense Switch.

Warning: To avoid bodily injury from hazardous electrical current, never remove the top cover of the device. There are no user-serviceable components inside.

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

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 speciﬁc problems listed in the table.
