Appendix B
Boot Sequence and
Downloading Software
This appendix provides a description of the IPmux-11 boot procedure via an ASCII
terminal for downloading software.
The file system can hold two compressed copies of the IPmux-11 code. One copy
is called the operating file, and the other is called the backup file. The operating
file is the default-executable IPmux-11 code. The backup file is used whenever the
operating file is absent or corrupted.
B.1 Booting IPmux-11
IPmux-11 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-11 configuration.
Accessing the Boot Manager
The Boot Manager menu is an option that allows the user to perform basic file
transfer operations. These operations are all optional.

To access the Boot Manager menu:
• Press <Enter> several times immediately after powering up the IPmux-11.
