The switch has a hardware failure; replace the unit and submit a Return Material Authorization
(RMA) to ShoreTel.


Booting via FTP.

Flash memory might be corrupted. Go to the Status > Switches page in the Diagnostics &
Monitoring System or the Quick Look page to ensure that the system is running properly.
 4 flashes

The IP address is unavailable.

DHCP and BOOTP did not respond to the IP address request, and the IP address is not
available in nonvolatile memory to continue the boot process. The switch will automatically
reboot in five seconds and try again. Check the BOOTP/DHCP server and the network
configuration to ensure that the voice switch is receiving a valid IP address.
 5 flashes

The operating system is not available.

The switch is booting from FTP but cannot find the boot files. It automatically reboots in five
seconds.
 6 flashes

The switch is using a previously stored IP address.

A BOOTP/DHCP transaction was attempted, but the BOOTP/DHCP server did not respond.
The switch continues to use the IP address stored in nonvolatile memory until it receives a
valid response. If the switch receives a response that provides a different IP address, it
reboots using the new IP address. If the switch receives a response that matches the IP
address stored in nonvolatile memory, it continues operation, and the power LED stops
flashing. If the problem persists, check the BOOTP/DHCP server and network configuration.
VxWorks
®
Command Line Interface
VxWorks
®
provides a variety of useful tools and debuggers. This command line interface offers access
to both standard VxWorks
®
commands and ShoreTel commands. You can access the VxWorks
®
interface by opening a Telnet session to a switch without invoking CLI.
You may also enter the VxWorks
®
command line interface from a serial interface by entering the
command gotoshell from the Shoreline> prompt. To return to CLI, enter the command cliStart.
Use caution when using the VxWorks
®
interface; running commands can degrade performance on the
switch. ShoreTel does not support changing or setting IP or other parameters using the VxWorks
®
interface. Changes made using this interface may not be persistent and using it may cause
unpredictable behavior in the system.
