1. Verify the SATA cable path in that area is
correct by comparing it to the display signal
drawing. If not, correct the signal path.
1 module out
1. Ensure the SATA and power cables to the
module are connected and secure.
2. A SATA cable may be damaged, replace
both SATA cables to the module to see if this
addresses the issue.
3. It is likely a bad module. Swap the module
with a replacement module and verify that the
new module functions correctly.
2 modules out
1. Check the status indicators on the back of the
modules. If the indicators are off, check the
power indicator on the power supply for the
affected modules. If the power supply indicator
is off and there is power connected to the
power supply, replace the power supply.
2. If there is power to the power supply and
the modules, check the SATA cables to the
modules. It is possible the SATA cables at the
beginning and end of the affected modules are
disconnected or bad.
