HP Modular Cooling System G2 rack is designed for high density server and blade deployments. It re-circulates and cools the hot server exhaust air through the heat exchanger residing in the MCS G2 unit. The air is then expelled in front of the enclosed rack at a much lower temperature providing sufficient cool air.

The MCS G2 unit contains six fans and a heat exchanger deployed along the full height of the rack to ensure that all the equipment installed receives sufficient chilled air. All fans are swappable while the unit is online, providing great servicing flexibility. Redundant power is ensured through a failover power switch that can be connected to two power sources. The environmental monitor controls the air temperature to the servers and adjusts automatically to meet the pre-established air temperature goal.
