Figure A-1. Boot Screen
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.
3. After decompression, the IPmux-1/1E software starts to execute and the user
can begin working.
Accessing the File System
The file system 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 file system;
• Press <Cntl-A> within this delay interval
The File System menu is displayed (see Figure A-2). .
If you do not press <Cntl-A> within three seconds, booting continues normally.
