Aviation Client Data Center

Textron Server Room Upgrade


PEC designed new electrical and mechanical equipment to provide the least impact on the existing data center.  The new electrical system consisted of 2N, 480V services fed from two different medium voltage unit substations. The feeds were connected to an automatic throw over (ATO) switchboard. Internally, the ATO fed two UPS distribution switchboards. The UPSs fed electrical panelboards within the room that fed the dual-corded servers. Single-corded equipment was fed from a static automatic transfer switch that switched power from the redundant UPSs. All power sources provided full redundancy to increase uptime and maintainability. A metering/monitoring system was installed to provide early problem notice to maintenance personnel.

A battery monitoring system was provided on each UPS to help with the early detection of battery failures. CRAC units were connected to the existing chilled water system and the second was connected to an existing condensing water system. The condensing water system was also provided with three-way valves to connect to the domestic water system. This provided multiple cooling sources in the event e cooling source failure. PEC also provided commissioning of the electrical power, control, and mechanical systems to prove the full functionality of those systems.
