Tech Note : For a detailed description of every light and their status, please read the
Status Light Behavior appendix.
SYSTEM Status Light: 1
While the USB Server is booting up, you will notice different lights turn on and off. The
following table explains what these lights mean during the boot up process.
STAGE 3
Checking Ethernet
Connection
SYSTEM 2 and SYSTEM 3 (both red) start flashing while the server looks for an
Ethernet signal (aka a physical Ethernet connection). SYSTEM 2 and 3 will flash
forever until the server finds this signal.
SYSTEM 2 and SYSTEM 3 (both red) flash while the server tries to obtain an IP
address. Once the server obtains its IP address, the server is completed booted up and
running. The status lights will now have a new meaning.
Tech Note : If the server is configured to use a Static IP address, the second stage is
completed immediately. For DHCP only, it waits for the DHCP server. For Zeroconfig
only, it takes about 1-2 seconds while it negotiates. For Default, it waits for DHCP for 10
seconds before taking a Zeroconfig address (1-2 seconds).
STAGE 4
Checking Ethernet
Connection
The ( green) USB 1-4 lights are turned ON as the firmware starts running.
STAGE 2
