Understanding The Plug In And Reset Process - Avaya B189 Installing And Maintaining

Understanding the plug in and reset process

Plug the phone into the Ethernet wall jack. The phone receives power from the port and
performs the following processes:
Note:
Do not unplug the phone during the download process. Wait for the download process to
complete. If the application was downloaded earlier, the whole process takes approximately
1 to 2 minutes after the phone is plugged in. For software upgrades, including the boot file
and application file download, the process might take 5 to 10 minutes. The duration depends
on factors such as LAN loading and the number of phones being installed.
1. The system checks the system initialization value for the language file in use
2. The boot programs check the Kernel or the Root File System that has previously

been marked as the one to be activated to ensure that it has not become corrupted.
If the Kernel or the Root File System is not corrupted, the system transfers control
to a process in that file system. If that file system is corrupted, the boot program
checks the other Kernel/Root File System. If that file system is not corrupted, the
file system is marked as the one to be activated. The system then sets the value of
RFSINUSE to the name of the Signed Kernel or Root Software Package that was
used to install that file system, and the control is transferred to the Signed Kernel
or Root Software Package. If both Kernel and Root File Systems are corrupted, the
system halts the processing. The software checks whether a Signed Application or
Library Software Package has been previously downloaded. If the system finds the
Application Software Package or the Library Software Package the Application
Software Package or the Library Software Package is installed. If either the
Application Software Package or the Library Software Package has a different file
name than the currently installed version, the system replaces the existing
corresponding files in the Application File System. The system then deletes the
downloaded Signed Application or Library Software Package. If a new Signed
Application or Library Software Package is not found, the integrity of the application
files is checked. If the files are corrupted, the system installs the files from the
Backup Package, replacing the corrupted files in the Application File System. Each
time an Application Software Package or a Library Software Package is installed,
the system sets the value of the persistent parameter APPINUSE to the file name
of the Application Software Package that was installed. If the application files are
not corrupted, or after the Backup Package has been installed, control is transferred
to the application installed in the Application File System. While the system loads
the application files into volatile memory and transfers control is transferred to the
application files, the bottom text line shows the value of the APPINUSE
parameter.
