In this case, the old user name will be used for the next login using the command line interface.
If you have forgotten the operator or guest user name and/or password, use “Bootloader Mode” to
change them. In Bootloader Mode, log in using the factory set user names (“operator”, ”guest”) and
passwords (
See “Command Line Interface” on page 29. ). Then use F100 PN and F100P to set the new
user names and passwords. Once this has been completed, reboot the unit and log in using the new
username or password.
See “F100 P – Change User Password” on page 95.
Bootloader Mode
To enter Bootloader Mode when resetting a forgotten user name (F100 PN) or password (F100 P):
• Reboot the XLi using the F100 K I L L – Reboot command.
• Immediately press the MENU key on the keypad and hold down while the XLi is rebooting. The
XLi will display will ‘hang’ while displaying “BOOTING”.
• After a few moments, release the MENU key.
• Open a command line session with the XLi.
• Use the F100 PN or F100 P commands as needed and then reboot the XLi again.
F108 – Oscillator Configuration
Note: The standard XLi IEEE 1588 clock features a TCVCXO oscillator. Other oscillator types are unavail-
able as options for the standard XLi IEEE 1588 clock.
Use function F108 to display the type of oscillator being used:
• TCVCXO
• OCXO
• HIGH (High Stability OCXO)
• RUBIDIUM
For more information, see “Standard TCVCXO Oscillator” on page 5 .
Command Line
The oscillator type is defined by the hardware configuration of the clock, and is not configured through
the command line or keypad/display user interfaces. To request the oscillator configuration, enter:
F108<S><CR>
The XLi responds:
F108<S>OSCILLATOR<S>CONFIG<S><OSC><CR><LF>
