Booting IPmux-16 A-1
Appendix A
Boot Sequence for
Downloading Software
A.1 General
This chapter provides a description of the IPmux-16 boot procedure via an ASCII
terminal for downloading software.
The IPmux-16 software is stored in the 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-16 code. One copy
is called the operating file, and the other is called the backup file. The operating
file is the default-executable IPmux-16 code. The backup file is used whenever the
operating file is absent or corrupted.
A.2 Booting IPmux-16
General
IPmux-16 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-16 configuration.
Boot Sequence
The following is a description of the boot sequence. If the system is working
normally, the entire process is completed within two minutes. Refer to Figure B-1.
