Key HP MCS G2 components
The HP MCS G2 comprises the key components described below (and shown in figure 3) that work
together to provide cooling performance:
 Main breakers—circuit breakers powering the HP MCS G2 (the breakers don’t control power at the
input panel at the rear of the unit)
 Heat exchanger module—the air-to-water heat transfer device was specially created for demanding
data center environments, and is the key component of the HP MCS G2
 Display—provides general cooling unit status
 Management module—provides users with Web-based capabilities to set, monitor, and control
temperature within the modular cooling unit and displays the health of the unit
 Fan controllers—operate the fans according to the cabinet air temperature
 Air bleeder valve—allows air to bleed out of the system when coolant is initially filled
 Water module—senses for condensation, leaks, water temperature, flow rate, and the status of the
variable valve and reports this information to the management module
 AC input/network connection—provides primary and (if available) secondary AC input connections
and management network interface
 AC transfer switch—provides dual AC power with a failover feature for redundancy
 Fans—provide circulation of cooled air through the computer equipment rack
 Water group—includes the variable valve, flow meter, check valve, and temperature sensors.
A condensation pump with overflow and condensation lines (not shown) connects to the water
group. There is one water group in each HP MCS G2.
