Flash Boot
The standard method for booting a ShoreTel voicemail-enabled switch is to boot from the switch’s flash
memory. When a switch is first powered on, it reads the boot parameters stored on the non-volatile
memory, which instructs the switch to load software from flash memory. When the software starts, it
loads its configuration, which is also stored in flash memory.
Default Button
The Default Button is the small “paperclip” button on the left side of the switch. Pressing this button
replaces the two configuration files with their default variants. The Compact Flash is not affected.
Pressing this button and holding for 10 seconds, in addition to replacing the configuration files,
removes all files from the Compact Flash.
FTP Boot
Booting from FTP is available when you cannot boot the switch from internal memory. When booting a
switch from FTP, the operating system and software are loaded from the FTP site identified in the boot
parameters. The loaded files define a default configuration.
Voicemail services on the switch are disabled after booting from FTP and are restarted only by booting
from Flash. After an FTP boot, the switch can perform telephony functions as those available through
other ShoreTel voice switches. Voicemail-enabled switches started with an FTP boot can operate only
as a voice switch (controlling phones, trunks, and call routing).
FTP boot is typically used for troubleshooting and also supports maintenance tasks and the backup
and restore facilities. FTP boot supports certain maintenance functions, such as an emergency boot if
the flash becomes damaged.
Burnflash
Burnflash forces a reboot and installs new software.
The burnflash command burns a ShoreTel image to the CF card. It unconditionally replaces the
resident image while rebooting the system, but it does not destroy any voicemail. The purpose of
burning the image to the CF is to enable the switch to boot from solid state memory instead of
performing an FTP boot from the server.
If a user created a static configuration for IP addresses and other system parameters through the
STCLI (option 3), those parameters must be reconfigured after burnflash runs.
