Factory reset using SSH, Telnet and serial connection
Only the C40, C60 and C90 codecs have standard serial port interfaces. please see
"Appendix C – Serial connections" on page 33 for more information regarding serial connection
setup. The EX, MX, SX and C20 systems require a special cable to access these systems via serial port.
Details on SSH and Telnet clients and their use is documented in "Appendix D – Useful software" on page 34.
Method 1 – If you can login as admin
•
login as admin.
•
Enter the command: xCommand SystemUnit FactoryReset Confirm: Yes
•
You will see the text:
*r FactoryResetResult:
** end
OK
•
if connected by SSH or Telnet, the session will shut down.
•
System restarts and a message on screen confirms the factory reset.
Method 2 – If can login as root
•
login as root using SSH, Telnet or connect via serial port.
•
Enter the command rm /mnt/base/active/config.db -
restart the codec using the command reboot.
•
This will remove all the settings from the system, but is not a full factory reset and there may be some
settings remaining e.g., local phonebook. it is recommended once the system is recovered to login as
admin and use Method 1 above to do a proper factory reset if a complete reset of the system is required.

Factory reset - physical reset method for C20,
EX60, EX90, MX200, MX300 and SX20
Before trying to perform factory reset with the physical method, you should first see if you can use one
of the other methods. See "Suggested methods" on page 22 for alternative methods of factory reset.
C20
•
Turn off the C20 by holding down the physical power button on the rear of the codec until
you see the shutdown message on your screen. release the button and wait for the system
to shut down.
Figure 24 - C20 Power Button
•
Once the system has completely shut down, press and hold the power button (approximately
8 to 10 seconds) until the green lED on the front panel of the codec starts blinking slowly.
Figure 25 - C20 LED
•
release the power button and push it twice in quick succession within the next 5 seconds.
•
You will now see the green lED flash more quickly.
•
The codec should now factory reset and restart. This can take a few minutes.
•
When the system starts up, you will briefly see a message on the screen confirming the
system was successfully factory reset and all settings have been removed.
