8 Troubleshooting

Q. My computer is not detecting or recognizing my PCIe card in the EB3T unit

A. Follow the steps below for troubleshooting

Shutdown the computer, this will also power down the EB3T unit.

Disconnect the Thunderbolt cable from the computer and EB3T

Unplug the power cord from the back of the EB3T unit.

Remove your PCIe cards.

Reinstall your card to another PCIe slot.

Reconnect the power cord.

Reconnect the thunderbolt cable to computer and EB3T.

Turn ON the computer, this should automatically power UP the EB3T.

Check your PCIe card, see if it is working now.

10.

If it is working, this means your card is working fine.

11.

Your next step is to plug in the card to the PCIe slot where you had before.

12.

Shutdown the computer and EB3T, disconnect the Thunderbolt cable and power cord.

13.

Move the PCIe card back to the original slot.

14.

Reconnect the power cord and Thunderbolt cable.

15.

Power ON the system again, check if your PCIe card is working or not.

16.

If it is not working, this means the slot is faulty.

17.

If you had tried / tested all the slots with the same PCIe card, and still showing the same issue, try another or different
PCIe card.

18.

If using another PCIe or different PCIe card fixes the problem, this means that the EB3T is working and the problem
points to your original PCIe card,

19.

If it fails to fix the problem by using another or different PCIe card, you may have a faulty EB3T unit or computer.

Q. My PCIe card(s) is /are no longer working.

A. Follow the steps below

First, check if there are five Solid Green LEDs illuminated on the Thunderbolt card.

Check if there are two Solid Green LEDs on the backplane.

Check if the SLOTS LED are illuminated ( you should see one Solid Blue LED and two or three Blue LEDS blinking)

If all LEDS are verified working, this means the EB3T has powered UP ok and working fine.

This also indicates that the Thunderbolt cable is working fine.

Your next step is to try another PCIe card, see if this card shows up or not.

If the card shows up, this means that your original PCIe card is faulty.

If the card is not showing up, try another computer.

If you have updated your Operating System, we recommend reverting to the last Operating System.

10.

If you have tried another computer, and reverted back to the last working Operating System and you are still having
problem recognizing your PCIe card, swap the entire EB3T unit, or contact Technical Support to service or repair the unit.

Q. My EB3T unit is not powering UP

A. Follow the steps below.

First check if there are five Solid Green LEDs illuminated on the Thunderbolt card.

Check if there are two Solid Green LEDs on the backplane. Check if the SLOTS LED are illuminated

If all LEDS are not illuminated do the next step.

Try another Thunderbolt cable.

If it fixes the problem by swapping the Thunderbolt cable, this means your original Thunderbolt cable is faulty.

If you are still having problem, try using a different or another computer with Thunderbolt3 ports.

If you are still having problem, do the next step.

Remove your PCIe card in the EB3T unit.

If removing the PCIE card fixes the problem, or the EB3T unit powers UP again, this means your PCIe card is causing a
short to the slot. Replace your PCIe card.

10.

If you are still having the same problem, check the Thunderbolt 3 card, see if the 3-wire cable is seated firmly and it is not
broken.

11.

Reseat the Thunderbolt 3 card.

12.

If you are still having problem, contact Technical Support, you may need to send your unit for service or repair.
