Appendix B – Gaining root access to your system
root access is disabled by default from TC4 onwards. However it can occasionally be useful to enable
this for troubleshooting.
it is critical to always set a password when enabling root access.
To enable root access login as admin and use the command:
systemtools rootsettings on [password]
replace [password] with the actual password you want to set for root access. When you enter this
command, your telnet/SSH session will close. After this you are able to login as root.
To check if root is enabled you can login as admin and enter:
systemtools rootsettings get
The system returns:
systemtools rootsettings get
on
OK
To turn off root access (default state):
systemtools rootsettings off

Appendix C – Serial connections
The C40, C60 and C90 have standard serial port interfaces. profile systems containing these codecs
will also have standard serial connectors.
The EX, MX and SX series need non-standard cables to access their serial ports. These should be
available to order in the near future, please contact your local Cisco representative for more details
on orderability.
With a modern pC or laptop with no standard serial connector, you will need a USB to serial adaptor
like the one illustrated here.
