HP Modular Cooling System Site Preparation Guide

Control System
The HP MCS includes a control system that constantly monitors the HP MCS air temperatures, water
temperatures, and flow rate. If the air temperature falls below a target setpoint, the HP MCS
management module will adjust the fan speed and or flow rate to maintain the setpoint
temperature. If the set point temperature cannot be maintained, the HP MCS management module
will generate an alarm and notify facility management systems as configured.
NOTE
For site evaluations and technical consulting services for your site please
refer to the HP MCS User Guide.
Connecting to Facility AC Power
The HP MCS accepts AC power through two C20-type power receptacles located at the bottom
rear patch panel. The HP MCS ships with two sets of AC power cords for connecting to redundant
AC power busses, if available. Figure 25 shows the two types of power cords shipped with the HP
MCS. The NEMA L6-20 power cord uses a NEMA L6-20 male plug for connecting to a facility AC
feed connector common to North America and Japan. The IEC 309 power cord uses an IEC 309
male plug for connecting to a facility AC feed connector common in various international regions.

At least one power cord must be used for operation of the HP Modular Cooling System. The second
cord can be connected to a redundant AC power bus to improve system availability. In this case,
the transfer switch assembly of the HP MCS provides switch-over to the active power bus in the
event of power source failures or accidentally tripped circuit breakers.
