Key MCS 5042 components

The MCS 5042 key components that work together to provide cooling performance include:

• Main breakers—Provides power for the MCS 5042 through circuit breakers (do not control power

at the input panel*).

• Heat Exchanger Module (HEX)—Includes an air-to-water heat transfer device specially created for

demanding data center environments.

• 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 controller—Operates the fans, according to the cabinet air temperature.

• Air bleeder valve—Enables air to bleed out of the system manually when coolant is initially filled.

• Water controller—Senses for condensation, leaks, water temperatures, flow rate, and the status of

the water 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 fail-over feature for redundancy.

• Fans—Provides circulation of cooled air through the computer equipment rack.

• Water group—Includes the water valve, flow meter, check valve, and temperature sensors.

A condensation pump with overflow and condensation lines connects to the water group. Each

MCS 5042 has one water group.

* If the MCS 5042 is still connected to a power source, voltage is applied before the circuit breakers at the input panel.
