4.3.4 Service and diagnostics
4.3.4.1 Booting of the TCU
Messages when booting
While the TCU is booting, progress is displayed after the BIOS has booted and before the
operating system is loaded. In addition to messages, the current booting status is also indicated
by a progress bar. While the IP address is being determined via DHCP and the TFTP is being
downloaded (boot image), a progress bar indicates that booting of the TCU is not yet complete,
or that a fault has occurred.
The structure of these messages is shown below:
Thin Client Boot loader V04.50.11.00

You can see the current boot phase in the third line. Below that you are told whether you can
call up information via <F1> if a fault occurs.
Diagnostics options during booting
In the following cases, the diagnostics window is displayed and booting of the TCU is
interrupted:
• When the <1/F1> function is selected during booting
• When a warning message is displayed

You can select the <1 / F1> to <F8> functions shown below using the horizontal softkeys on
the OP. For example, to select <F7>, press the horizontal softkey 7.
