When installing a Modular Cooling System (MCS) G2, which safely considerations must be

implemented? (Select two)

A.
Install the MCS G2 free of the adjacent racks

B.
Plug the power supply cables for the MCS G2 in grounded sockets

C.
Verify the maximum water pressure in the MCS G2 does not exceed 0.4 bar (6 PSI)

D.
Use aluminum piping for the water supply

E.
Attach the MCS G2 rack to the grounding system

F.
Verify the temperature inside the MCS G2 does not exceed 20 degree Celsius (68 Fahrenheit)

The HP MCS G2 offers on incremental data center cooling solution that is capable of cooling 35
kW of heat from one IT rack or two IT racks. The two basic ways to deploy the HP MCS G2 are as
a standalone unit or to place it in a row adjacent to other HP MCS G2 units or standard equipment
racks.

The HP Modular Cooling System G2 is tested to the maximum pressure (PS) of 8 bar (116 PSI)
without fluid trapped inside by closed, external valves.

The charts in figures 27 and 28 offer a guideline for determining the approximate amount of heat
that can be removed from HP MCS G2 single and dual rack configurations based on 20°C (68°F)
and 25°C (77°F) server intake air temperatures (in degrees Celsius) and flow rates (in liters per
minute m] or gallons per minute [gpm]) being delivered to the unit.
