6.2.2 Power supply issues
The TP6 power supply provided with TD4 is capable of powering TD4 and nearly
all combinations of drives. If your TD4 will not turn on, check the status of the DC
power LED on the plug at the end of the TP6 power supply output cord. If the blue
ring is not lit up, then check to make sure the AC power cord is plugged into the TP6
and that the other end is plugged into a live AC outlet. If all that checks out, it is
likely your TP6 power supply has failed. If you suspect your TP6 has failed, contact
OpenText My Support at https://support.opentext.com to initiate repair/replacement
actions.
Regarding external drive power, TD4 employs staggered power sequencing for the
source and destination drives. With staggered sequencing, power is first provided to
one drive, then, after a brief delay, to the second drive, and so on. This feature
prevents large current demand spikes at initial power-up when many drives are
connected, which helps to ensure reliable operation even with a heavily loaded
system. Due to staggered power sequencing, it is normal to hear the source and
destination drives spin up separately.
TD4 is constantly monitoring its internal voltages. If any of them are out of
specification, the unit will be shut down and the power button LED will flash. If this
occurs, remove all drives from the unit, remove the power cord from the back,
reconnect it, and then attempt to turn your TD4 on again. If the problem persists,
contact OpenText My Support at https://support.opentext.com to initiate repair/
replacement actions.
6.2.3 Thermal issues
TD4 is constantly monitoring the operating temperature of key components inside
the unit. While it was designed to have plenty of operating temperature margin,
conditions that affect the airflow or the effectiveness of the cooling system inside the
unit can occur. Depending on the severity of the issue, overheating can possibly
cause performance issues, functionality issues, or physical damage to the unit.
Should any of the key TD4 components become overheated for any reason, a
warning will be provided in the top navigation bar (dark blue bar across the top of
the home screen). The first level warning will be a yellow thermometer icon which
indicates temperatures are on the rise and above a set threshold. A yellow thermal
warning indicates that the unit is running abnormally hot but is still within its
normal operating temperature range. If you see this yellow thermal warning, check
to make sure the fan inside the unit is running and that none of the vents (inlet or
outlet) are blocked. If everything looks okay and the yellow thermal warning
persists for more than one hour, turn the unit off and let it cool for a few minutes
before attempting to use it again. If after powering the unit up again, the yellow
thermal warning returns and persists for more than one hour, contact OpenText My
Support at https://support.opentext.com for further guidance.
The second level thermal warning will show a red thermometer in the top
navigation bar. A red thermal warning indicates the unit has hit an extreme
temperature threshold at which functionality can no longer be guaranteed and
