when the initial system boot is complete, verify the following:

    1 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.

    2 that the system fan assembly is operating

    listen for fan activity. the fan tray led should be green during operation.

    3 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.

    4 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.
