Troubleshooting the Installation
This chapter describes how to troubleshoot the switch hardware installation and
contains these sections:
• Getting Started, page 5-2
• Problem Solving to the System Component Level, page 5-2
• Identifying Startup Problems, page 5-3
• Troubleshooting the Power Supply, page 5-5
• Contacting Customer Service, page 5-6
If your system has problems starting up, use the information in this chapter to help
isolate the cause. Problems with the initial startup are often caused by poor or
improper connections. Although temperature conditions above the maximum
acceptable level rarely occur at initial startup, environmental monitoring
functions are included because they also monitor DC-line voltages.
Note For configuration questions or problems, refer to the software configuration guide
or the command reference publication.
