Troubleshooting
This chapter explains how to isolate and diagnose problems with the
BayStack 350 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 350 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 4-3 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.
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).
