Troubleshooting

This chapter describes how to isolate and diagnose problems with your

BayStack 410-24T switch.

This chapter covers the following topics:

• Interpreting the LEDs

• Diagnosing and correcting the problem

-- Normal power-up sequence

-- Port connection problems

• Software download error codes

The chapter topics lead you through a logical process for troubleshooting the

BayStack 410-24T switch. For example, because LEDs provide visual indications

of certain problems, refer to “

Interpreting the LEDs” on page 4-2 to understand

the various states (see Table 4-1

) that your switch LEDs can exhibit during normal

operation.

For more help in determining the problem, “

Diagnosing and Correcting the

Problem” on page 4-4 describes symptoms and corrective actions (see Table 4-2)

you can perform to resolve specific problems. Subsequent sections give

step-by-step procedures to correct the problems.
