ShoreTel Voice Switch Boot Options
When a ShoreTel Voice Switch boots, it requires an IP address to connect to the network and an
application program. ShoreTel Voice Switches are set to use a DHCP server for an IP address and to
retrieve the application from the switch’s flash memory.
If a DHCP request receives no response, the switch tries a BootP request as a backup. ShoreTel
recommends using static IP parameters configured via the serial port, as this is much more reliable. If
DHCP is to be used, ShoreTel strongly recommends using DHCP reservations for each switch so that
the DHCP lease is not lost.
If a DHCP server is not available, you can set the IP address manually from the switch’s maintenance
port.
The standard method for booting a ShoreTel Voice Switch is to boot from the switch’s flash memory.
When a ShoreTel Voice Switch is first powered on, it reads the boot parameters stored on the boot
ROM, 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.
Booting from FTP is available for instances when you cannot boot the switch from flash memory. When
you boot a switch from FTP, the operating system and software load from the FTP site identified in the
boot parameters. The loaded configuration is a configuration received from the TMS server.
If the switch fails to load the application from flash and does not have the IP address of the ShoreTel
server, you can set the IP address and boot parameters by connecting to the maintenance port and
using the configuration menu. The configuration menu allows you to set the IP address of the switch
and enter the ShoreTel server (boot host) IP address.
