2.3 LED Modes of Operation
The BH560v2 is running an embedded version of the Linux operating system. Because the
BH560v2 is running an operating system, it maintains some of the OS characteristics, such as
boot modes. Similar to Microsoft Windows®, Linux has normal and safe boot modes. Safe
mode exists to prevent the device from being put into a state where it can’t boot or be restored to
a normal mode of operation.
Depending on certain events the BH560v2 may boot into safe mode. For example, if the device
does not complete a boot cycle into normal operating mode after ~5 tries, safe mode is activated.
This scenario is common if you power cycle the device too many times and don’t allow it to
complete the boot cycle. The following paragraphs describe how you can identify these
operating modes.
•
Normal Operating Mode
Normal operating mode can be identified when the device completed its boot sequence,
which could take between 20 and 30 seconds, and both LEDs are on steady Green. See
Figure 4 for location and orientation of these LEDs on the BH560v2 end panel.

•
Safe Mode
Safe mode can be identified when the device is powered and the MODE LED is on blinking
Red. See Figure 5 for location and orientation of these LEDs on the BH560v2 end panel.
To clear safe mode, please refer to the section on the Bh560v2Config utility.
