Booting IPmux-1/1E A-1
Appendix A
Boot Sequence for
Downloading Software
This appendix provides a description of the IPmux-1/1E boot procedure via an
ASCII terminal for downloading software.
The IPmux-1/1E software is stored in flash memory in two sections, in the boot
sector and in the file system. The boot sector holds a boot program that calls up
the rest of the program from the file system.
The file system can hold two compressed copies of the IPmux-1/1E code. One
copy is called the operating file, and the other is called the backup file. The
operating file is the default-executable IPmux-1/1E code. The backup file is used
whenever the operating file is absent or corrupted.
A.1 Booting IPmux-1/1E
IPmux-1/1E boots up automatically. After powering up, no user intervention is
required, except when the user wants to access the file system to modify or update
the software or the IPmux-1/1E configuration.
Boot Sequence
The following is a description of the boot sequence. If the system is working
normally, the entire process is completed within 30 seconds. Refer to Figure A-1.
