Default Credentials for Cisco T3

Password: tec

T3 Touch Panel / WebStart GUI

Changing the TCU password (VNC and SSH)

  1. Physically attach a keyboard to the TCU (or log in with VNC)

  3. File -> New Task (Run…)
  4. “cmd” to bring up a command prompt
  5. Type: "net user administrator <new password>"
  6. Type: "control userpasswords2". A window will pop up.
  7. Check the box “Users must enter a user name and password to use this computer” and Apply
  8. Type "control userpasswords2" again, uncheck the box, and apply.

Changing the touch panel password (Also WebStart GUI password)

  1. Log into the touch panel (Touch and hold the upper left corner until the login screen appears)
  2. Go to Change Passwords
  3. Enter new password for Admin or Operator user

The Operator user is an Admin user with limited privileges. Make sure you change the dropdown box to Admin to change the correct password.

Note: For the WebStart GUI you must use Java 6.x since Java 7.x will not authenticate. The bug ID for this is CSCug84596.
