above which the unit could possibly be damaged. Check that there are no
obstructions to the inlet or outlet air vents, and let the unit cool down for a few
minutes before attempting to use it again. If the red thermal warning condition
returns, please immediately shut down the unit and contact OpenText My Support
at https://support.opentext.com for further guidance.
Caution
If your TD4 shows a red thermal warning in the top navigation bar on the
home screen, it is highly recommended that you immediately power off
your TD4. If the power button is unresponsive, remove the power from the
rear of the unit. Check that there are no obstructions to the inlet or outlet air
vents, and let the unit cool down for a few minutes before attempting to
use it again. If the red thermal warning condition returns, please
immediately shut down the unit and contact OpenText My Support at

6.2.4 Problems with drive detection
When using a product like TD4, the most common problem you may encounter is a
failure to achieve drive detection. Most drive detection problems are the result of
improper cabling. The following table lists the most common drive detection
problems and possible corrective actions.
Problem Possible Corrective Action
General drive detection Check the power and signal cable connections between TD4
and the drive to ensure that all connectors are properly
seated. If TD4 still does not detect the drive, cycle the power
to attempt to detect the drive during a fresh start-up
sequence.
PCIe SSD is not detected While TD4 supports hot insertion of PCIe drives, it is
possible that doing so may cause drive detection issues that
would otherwise not occur. If you hot insert a PCIe drive (via
an appropriate Tableau PCIe adapter) and it does not detect,
power off the unit, connect the PCIe drive/adapter to TD4,
and then power on the unit.
Note that the m.2 drive stick form factor is not exclusive to
PCIe drives. SATA SSDs exist in that same form factor, and
they can physically be plugged into the Tableau TDA7-2
PCIe adapter. Such a setup will result in no drive detection. If
you experience no detection on an m.2 SSD, verify that it is a
PCIe (AHCI or NVMe) drive. If it is a SATA m.2 drive, try
connecting the drive to your TD4 with a Tableau TDA3-3
mSATA / m.2 SATA SSD Adapter.
