Is the power-and-cooling module DC Voltage/Fan
Fault/Service Required LED amber?
Is the drive enclosure back panel OK LED off?
Answer Possible Reasons Actions
No System functioning properly. No action required.
Yes The power supply unit or a fan
is operating at an unacceptable
voltage/RPM level, or has
failed.
When isolating faults in the power-
and-cooling module, remember that
the fans in both modules receive
power through a common bus on the
midplane, so if a power supply unit
fails, the fans continue to operate
normally.
• Check that the power-and-cooling
supply FRU is firmly locked into
position.
• Check that the AC cord is
connected to a power source.
• Check that the AC cord is
connected to the power-and-
cooling module.
Answer Possible Reasons Actions
No System functioning properly No action required
Yes • The expansion module is not
powered on.
• The controller module has
failed.
• Check that the drive is fully
inserted and latched in place,
• Check that the enclosure is
powered on.
• Check that the AC cord is
connected to a power source.
• Check the event log for specific
information regarding the failure.
