Appendix B Boot Sequence for Downloading Software Installation and Operation Manual
B-2 Booting IPmux-8/16 IPmux-8/16 Ver. 6.00
Boot Sequence
The IPmux-8/16 boot procedure comprises the following stages:
1. The boot program searches for the operating file in the file system:
 If the file exists, a message appears on the screen and the program
continues.
 If the file does not exist, the boot program searches for the backup file,
renames the file to Operating file (a message appears on the screen) and
continues.
 If there is no backup file, you must download a file via the out-of-band
interface (XMODEM protocol). The received file is saved as the operating
file in the file system.
2. Files in the file system are compressed and automatically decompressed into
the RAM memory before execution begins. A message appears on the screen.
After decompression, the IPmux-8/16 software starts to execute and the
user can begin working.
If the system is working normally, the entire process is completed within
two minutes.
Accessing the Boot Menu
The boot menu is an option that allows the user to perform basic file transfer
operations. These operations are all optional.
If an operating file exists in the file system, there is a three-second delay. To access
the boot menu, press <Ctrl+A> within this delay interval; the boot menu is
displayed. (If you do not press <Ctrl+A> within three seconds, booting will
continue normally.)
From the boot menu, you can:
• Exchange the operating and backup files
• Download a new operating file; the previous operating file is saved as the
backup file
• Delete the operating file; the backup file becomes the operating file
• Delete the configuration file
• Delete all the software and configuration files.
If you choose to exchange or delete a file, you are prompted for confirmation.
