• Ensure that the Ethernet port on the device is enabled and active.
• Remove and reconnect the Ethernet cable.
• Try a different Ethernet port, if possible.
• Try a different Ethernet cable.
• If a switch or hub is being used, check that it is powered on and correctly configured.
• Disable and then enable the PC Ethernet port, or other conventional Ethernet device, to
which the Ethernet cable is attached.
In the unusual case that a supplied Ethernet cable is defective, Intrepid will replace it.
Automotive Ethernet Link LED(s) not Illuminated
The RAD-Star is not linked correctly to its attached BroadR-Reach device(s). Since BroadR-
Reach devices and cables vary, this issue may be application-dependent, but please try the
following:
• Ensure that a connection from the RAD-Star's BR MSTR port goes to an ECU or
BroadR-Reach switch port configured as a slave device; similarly, any connection from
the BR SLAVE port should go to an ECU or switch port configured as a master. If you
are unsure, try switching the connections.
• Double-check the connections at both ends of the cable(s).
• Remove the cable from the RAD-Star and reconnect it.
• Check for a loose connection at the Automotive Ethernet device.
• Try a different cable, if possible.
SLAVE, or vice-versa, be sure to make the corresponding change
to which RAD-Star conventional Ethernet port is attached (MASTER
to SLAVE or vice-versa).
Only One Automotive Ethernet Link LED Illuminated After Swapping Devices
Normally either both link LEDs will light up (correct master/slave configuration) or neither will
(incorrect configuration). If only one link LED illuminates, try swapping the devices again:
• If the illuminated link LED changes after swapping devices, the problem is with the
device connected to the RAD-Star BroadR-Reach port that is not illuminated.

Note: If you are using the RAD-Star as a media converter and
switch the BroadR-Reach connection from BR MSTR to BR
