Cisco TelePresence System Codec C90 トラブルシューティングマニュアル

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

•

Enter the command: xCommand SystemUnit FactoryReset Confirm: Yes

•

You will see the text:

*r FactoryResetResult:

** end

•

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

•

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.

•

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.

•

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.
