Basic Switch Configuration
Booting the Switch
When you turn on the switch power supplies, the switch begins its automatic boot process. The default boot order is to try to boot the switch first from the PCMCIA card, then from the internal flash memory, and finally over the network. If a terminal is connected to the Console port, you can watch the system messages that record the boot sequence. You can modify this boot order using the boot monitor command line interface (CLI).
While the Passport 8190SM module is booting, the I/O modules boot using their local image files, which check for the presence of a Passport 8190SM module in the chassis. When the Passport 8190SM module has completed its boot process, the I/O modules transmit a load request. Messages on the console screen indicate the request and the completion of the image load. Then the I/O modules reboot using the newly loaded image. The entire boot sequence for the switch can take up to one minute.
When the switch starts booting, you can access the boot monitor by pressing any key during the first 4 seconds of the boot sequence. For details about the boot monitor and using the command line interface to modify the boot process, refer to Getting Started with the Passport 8100 Management Software and Reference for the Passport 8000 Series Command Line Interface Switching Operations.
