Chapter 1: Overview
The HP mc-Series 5042 Rack (“MCS 5042”) is a supplemental cooling system for the data center that
offers two configuration options:
• Preconfigured with a single HP 642 1200mm IT rack enclosure (Figure 1A)
• Configured to support two HP 642 1200mm IT rack enclosure (The second IT rack is a field-
installed option, as shown in Figure 1B).
Throughout this chapter, to ensure that all data is considered for a successful site preparation, the
various specifications and aspects of the system are defined.

To provide dedicated cooling of servers and other IT equipment, the MCS 5042 integrates with the
facility chilled water plant or a dedicated chilled water loop. To supply the MCS 5042, HP
recommends that you install a dedicated cooling loop. The system provides cooling, recirculation, and
condensation management, and it requires a small amount of AC electric power. Internal monitoring
and control sensors assure server inlet air set points are achieved and provide constant performance
feedback through local and network interfaces.
