Power Supply and Cooling Fan Features

The MD3600f Series storage array includes two integrated, hot-swappable

power supply/cooling fan modules. Both modules must be installed to ensure

proper cooling. The system requires at least one of the cooling fans to

function to avoid overheating.
A power supply/cooling fan module can be replaced without powering down

the system. For information on removing and installing the modules, see

"Power Supply/Cooling Fan Module" on page 257.

CAUTION:

A power supply/cooling fan module can be removed from a powered-

on enclosure for a maximum period of 5 minutes. Beyond that time, the system may
automatically shut down to prevent damage.
