IOS The line card is enabled and ready for use.
RUN
1. The sequence shown in Table 4-2 might occur too quickly for you to view; therefore, this sequence is provided
as a baseline for how the line cards should function at startup
2. The fabric downloader loads the Cisco IOS software image onto the line card.
Note If you have a Flash memory card installed in PCMCIA slot 0, the Flash memory card
contains a valid, bootable Cisco IOS software image, and the software configuration
register is set to 0x0102, the system will automatically boot this Cisco IOS software image.
The system then enters the setup facility where you will be prompted to perform a basic
configuration of the system (as shown in Step 6).
Otherwise, the system will enter the ROM monitor, and the ROM monitor prompt will
appear (>). In this case, you must proceed to Step 5.
If the ROM monitor prompt (>) appears, you then have to boot the Cisco IOS
Step 5
software image you want to use by entering the appropriate b command at the
ROM monitor prompt (>):
•
b—Boots the default system software from onboard Flash memory (if it is
present in onboard Flash memory)
To prevent system problems, use the b flash command option carefully;
Caution
otherwise, you might instruct the system to boot a non-Cisco IOS software image from
Flash memory.
