FN/LN/CN Router Boot Prerequisite
The PCMCIA/Floppy switch on the Flash System Controller board of an FN™,
LN
®
, or CN
®
determines where the router looks for the image (ace.out) and
configuration file when it is booting. The PCMCIA (Personal Computer Memory
Card International Association) position is for memory card boot access, and the
Floppy position is for diskette boot access.
You can use Site Manager and the Technician Interface to access both the memory
card and diskette files, regardless of the position of this switch. But you cannot
override the switch setting when booting. For example, you cannot boot from a
diskette if the switch is set in the PCMCIA position.
When you use the Site Manager to boot the router, or to specify an image and
configuration file in a Technician Interface
boot command, the software verifies
the file’s existence before allowing the boot to take place.
If the PCMCIA/Floppy switch is in the PCMCIA setting and you boot the router,
the following occurs:
1. The router boots from 1:ace.out if it is available. If not, it boots from
2:ace.out if it is available. If both are unavailable, a boot error occurs.
2. The router configures from 1:config if it is available. If not, it configures from
2:config if it is available. If both are unavailable, a configuration error occurs.
Booting a Router
To boot a Bay Networks router, start from the Site Manager main window and
follow these steps:
1. Select Administration➔Boot Router.
The Boot Router window shows default filenames for the router software
image and the configuration file (F
igure 7-1).
