TROUBLESHOOTING AND FAQ
9.1
All 100BASE-T1 LEDs are lit permanently
If all 12 LEDs for the 100BASE-T1 ports are on permanently without any link, the
software of the microcontroller is broken. In this case, nothing can be done by the user.
Please send the MediaGateway back to Technica Engineering GmbH. Please follow
the instructions on our homepage -> “Kundendienst” for return:

9.2
Four 100BASE-T1 LEDs of one Switch are lit permanently
If 4 LEDs from one switch are on permanently without any link, this switch is damaged.
It is possible to use the switches, that are still connected to the microcontroller (S1-
P4).
=> Switch 2 is damaged, switch 1 is still working.
=> Switch 3 is damaged, switch 2 and 1 are still working.
If the first switch (Switch 1) is damaged, the MediaGateway is not working anymore.
If there is still warranty, please send it back to Technica Engineering GmbH and we will
provide you with a new one.
Also, if there is no warranty any more, you can send it back and our team will try to
repair the device. In some cases, these devices perform efficiently again.
9.3
No access to webserver anymore
If the configuration port is correctly configured and you should have access normally,
the microcontroller is jammed by too much traffix. Please use a valid VLAN
configuration and avoid too much traffic on microcontroller port. For example, too
much broadcast packets hit the microcontroller.
9.4
Host LED is blinking fast
Usually the firmware update failed, and the host is still in bootloader mode. Please
restart the device and try to update the application again as described in this manual.
By using another Ethernet adapter, it might work better. Please use your integrated
LAN adapter of your PC or Laptop.
