Power input to the TS-7100 is supplied via the power input connector, refer to that section for information on voltage ranges for this device.

Once power is applied to the whole device, there will be output on the debug console port. The following section of the manual provides information on getting the serial console connected.

Note: The "*** Warning - bad CRC, using default environment" message can be safely ignored when the unit is first booted. This means that no environment variables have been saved to disk, and U-Boot is falling back to the default. If "env save" is run, this will save the environment to disk, and this message will go away unless there is a further issue.


The default U-Boot boot process will check for USB updates before attempting to boot from on-board eMMC. Details about the bootup process, features, and other U-Boot information can be found in the U-Boot sections.
