Note: For a detailed description of every light and its status, please read
A: Status Light Behavior.
While the UBox is booting up, different status lights turn on and off. Once the UBox is
running, the status lights have new meanings that help troubleshoot the UBox.
Boot-Up
The following table explains what the SYSTEM status lights mean during the boot-up
process.
SYSTEM Status Light 1
Look at the SYSTEM status light 1 (the green leftmost light under SYSTEM).
Status Condition Suggestions
Off
The UBox does not have power. Check the UBox's power supply and its
connection to an outlet.
On
If this light does not blink on/off within
6 seconds, the UBox has failed to boot
up.
Please follow the instructions in Resetting the
UBox Hardware on page 55.
Blinking Slowly
This is normal and indicates the UBox
hardware is working.
Proceed to the next light.
Alternating On/Off
with SYSTEM
Lights 2 and 3
If the SYSTEM 1 (green) light
alternates on/off with either SYSTEM
2 or 3 (red), so that when SYSTEM 1
turns off, SYSTEM 2 or 3 turns on
and
vice versa, the UBox has encountered
an error while loading its firmware.
