The system hardware employs front-to-rear air cooling technology. Cooling air enters the cabinets through the openings near the bottom of the front doors, and heated air is exhausted from the rear of the cabinets.

Cold aisles are the aisle spaces between two rows of cabinets that face each other, front to front. A cabinet row with the front facing open space is also called a cold aisle.

Hot aisles are the aisle spaces between two rows of cabinets that are aligned rear to rear. A cabinet row with the rear facing open space is also considered a hot aisle.

The cold aisle must remain cold. Do not attempt to cool down hot aisles. They are intended to be hot, and are not an indication of environment problems. As long as the cold aisles remain cold, according to environmental requirements, the state of the hot aisles is irrelevant.
