HP Modular Cooling System frequently asked questions

Question	Answer
What cooling capacity ranges are	The cooling capacity of the heat exchanger units depends on the
available in the MCS unit?	water supply temperature and the server inlet set point. The MCS
	unit is capable of cooling rack-mounted components consuming up
	to 35 kW of electrical power.
Is special IT equipment required for	No, all IT equipment that uses the front-to-back cooling system (99%
use with the MCS unit?	of IT equipment) can be used without restriction in conjunction with
	the MCS unit.
Does the additional heat from the	In some cases, up to 10% of the total power supplied to the rack
MCS unit increase the room	may be lost to the room, depending on the server air setting and the
temperature?	room temperature.
Can the level of heat removal be	Yes, the control system automatically adjusts the water flow and air
regulated in proportion to the waste	flow to remove heat generated in the rack.
heat generated?
How is water connected to the MCS	The water is connected to the unit using a 1 1/4 in flexible hose
unit?	and quick-disconnect automatic shutoff hose fittings. For more
	information, see the HP Modular Cooling System Site Preparation
	Guide on the HP website.
Can the MCS unit operate with the	Yes, due to the air curtain effect, the air will function normally with
front or rear door open?	little air lost. When the doors are open during operation, room air
	mixes with air supplied to the servers.
Does the MCS unit require	No, assuming that the water quality is maintained, the MCS unit is
maintenance?	maintenance-free. For more information about water quality, see the
	HP Modular Cooling System Site Preparation Guide on the HP
	website.
Is a false floor necessary?	No, a false floor is not necessary to operate the MCS unit. For more
	information, see the HP Modular Cooling System Site Preparation
	Guide on the HP website.
Does condensation form?	During normal operation some condensation may form, but the MCS
	unit condensation control system ensures that the condensation does
	not reach any rack-mounted components or cause any damage. In
	most cases, the condensation evaporates prior to reaching the MCS
	unit condensation control system.
How does the MCS unit control	There is some room-air interchange, so the moisture content of the
humidity?	air inside the unit is the same as the room.
