Troubleshooting

This chapter explains how to isolate and diagnose problems with the BayStack
350 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 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.
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.
