Note This chapter covers only the chassis component hardware aspects of
troubleshooting. For configuration issues, refer to the software configuration
guide or command reference for your switch.
System Boot Verification
When the initial system boot is complete, verify the following:
• That the power supplies are supplying power to the system
The LEDs should be green. Use the show environment Cisco IOS command
to view power supply activity.
• That the system fan assembly is operating
Listen for fan activity. The Fan tray LED should be green during operation.
• That the system software boots successfully
Hook up a terminal and view the startup banner. Use an RJ-45-to-RJ-45
rollover cable to connect the console port to a PC with terminal emulation
software set for 9600 baud, 8 data bits, no parity, and 1 stop bit. Watch for
any messages after startup.
• That the supervisor engine and all switching modules are installed properly
in their slots, and that each initialized without problems
If all of these conditions are met and the hardware installation is complete, refer
to the software configuration guide and command reference publications for your
switch so that you can troubleshoot the software.
If any of these conditions is not met, use the procedures in this chapter to isolate
and, if possible, resolve the problem.
