Power Supply and Cooling Fan Features

The MD3600i Series storage array includes two integrated, hot-swappable power supply/cooling fan modules. Both modules must be installed to ensure proper cooling. Each module contains two separate cooling fans. 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 replacing the modules, see "Power Supply/Cooling Fan Module" on page 224.

CAUTION: A power supply/cooling fan module can be removed from a powered- on system for a maximum period of 5 minutes. Beyond that time, the system automatically shuts down to prevent damage.
