5.4.13.7.1 Reboot
The Ground Station can be rebooted remotely by the TSC. This can be done on the page ’Software’
within the section ’Restart/Reboot.
By selecting the corresponding ’Kernel Partition’, it is possible to reboot the currently running kernel,
or to make a ’kernel switch over’ and boot the currently not running kernel.
Start the reboot procedure by clicking on the ’Reboot’ button. First, the user has to confirm the inten-
tion to reboot within a confirmation window by clicking on the ’OK’ button. Then a terminal pops up
(’reboot’), requesting the supervisor’s password.
After entering the correct password, the rebooting process will continue with any further user interca-
tion. The progress of the reboot process depends on the selected ’Kernel Partition’. Fig. 5−31 shows
an example for rebooting the currently running kernel
Fig. 5−31 Reboot terminal log without kernel switch (example)
If booting the currently not running kernel, a ping test on the IP−address of the current RCMS, stored
in the NVRAM, is performed (see Fig. 5−32). If the ping test is successful, then the kernel switch is
supposed to have successfully finished. In case of failure, the old kernel is rebooted.

If the rebooting is successfully done the instruction string "Press return to close!" appears in the win-
dow (see Fig. 5−31). So press the <RET> key to close the terminal window.
To see if a kernel switch has been successful, just press the green ’Refresh’ button in the middle of
the ’Software’ page (see Fig. 5−17) and then, after rebooting, check if the contents of the ’Kernel Parti-
tion’ field within the ’Current Configuration’ section shows the right running kernel.
