Keysight APM0100E 100BASE-T1/Ethernet Media Converter User Guide 29
Data Sent by the Automotive Ethernet Device is Not Received
Check the Rx LED on the 100BASE-T1/Ethernet Media Converter. If it is not
flickering, then data is not received by the 100BASE-T1/Ethernet Media
Converter. Double-check the attached device to ensure that it is transmitting, and
the BroadR-Reach (100BASE-T1) cable is functional.
If the
Rx LED is lighting up, check the link to the conventional Ethernet device,
and try a different cable if possible.
If both attached devices and cables seem to be correct, the issue may be with the
100BASE-T1/Ethernet Media Converter; then, contact Keysight “Service and
Support” on page 34.
Data Sent by the Conventional Ethernet Device is Not Received
The conventional Ethernet side has combined transmit and receive LEDs, so first
disconnect the BroadR-Reach (100BASE-T1) cable from the 100BASE-T1/
Ethernet Media Converter. This action will ensure that any flickering of the Activity
LED indicates data received by the 100BASE-T1/Ethernet Media Converter from
the conventional Ethernet device (rather than data the 100BASE-T1/Ethernet
Media Converter is transmitting). By performing this action, if you do not see this
LED lighting up, the device may not be transmitting, or there may be a problem
with the regular Ethernet cable.
If the
Activity LED is lighting up, reattach the BroadR-Reach (100BASE-T1) cable
to the 100BASE-T1/Ethernet Media Converter, and check the connection to the
Automotive Ethernet device. Try with a new cable if possible.
If you are unable to resolve the issue, contact Keysight
