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.
