Troubleshooting: Your Array 293
CAUTION: Power supply/cooling fan modules are hot-swappable. The array can
operate on a single power supply; however both modules must be installed to
ensure proper cooling. A single power supply/cooling fan module can be removed
from a powered-on array for a maximum period of five minutes. Beyond that time,
the array may automatically shut down to prevent damage.

Reseat the power supply by removing and reinstalling it. See "Power Supply
and Cooling Fan Features" on page 29.
NOTE: After installing a power supply, allow several seconds for the array to
recognize the power supply and to determine if it is working properly.
If the problem is not resolved, see "Getting Help" on page 303.
