Troubleshooting the Installation
This chapter describes how to troubleshoot the switch hardware installation and contains these sections:
• Getting Started, page C-2
• Problem Solving to the System Component Level, page C-2
• Identifying Startup Problems, page C-2
• Troubleshooting the Power Supply, page C-4
• Contacting Customer Service, page C-4
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.
