Troubleshooting Procedures

This section provides troubleshooting procedures that can be used to identify components within the disk
array that have failed.

Fan Module

The disk array enclosure is designed to ensure proper airflow with two fan modules operational, regardless
of the number of disk modules installed. No filler panels are required for empty disk module slots. All three
fans must be installed for proper airflow.
If a fan module fails, an amber fan status light indicates that the fan speed is too slow or that the fan has
stopped blowing air. A failed fan module has no airflow. If two fans fail, power will automatically shut
down to avoid overheating.

Power Module

Each power module contains a power supply with an internal fan for cooling. Three power modules
(redundant configuration) use active current sharing to distribute the power load. If one power module fails
or is removed, or if one of the ac power cords is accidentally removed, the other two power modules take
over the entire power load for the enclosure without interruption.
CAUTION! The following conditions will cause a power module to shut down
automatically:
two failed fan modules;
a power module internal fan failure or other internal failure;
an over-current condition caused by a faulty disk module or by using an unsupported
disk type with an excessive current rating.
