Using the BayStack 380 10/100/1000 Switch
Chapter 4
Troubleshooting
This chapter describes how to isolate and diagnose problems with your BayStack
380 Switch and covers the following topics:
• “Interpreting the LEDs,” next
• “Diagnosing and correcting problems” on page 174
— Normal power-up sequence
— Port connection problems
The chapter topics lead you through a logical process for troubleshooting the
BayStack 380 Switch. For example, because LEDs provide visual indications
of certain problems, see “Interpreting the LEDs” on page 172 to understand the
various states (Table 82) that your switch LEDs can exhibit during normal
operation.
For more help in determining the problem, “Diagnosing and correcting problems”
on page 174 describes symptoms and corrective actions (Table 42) you can
perform to resolve specific problems. Subsequent sections give step-by-step
procedures to correct the problems.
