DECarray Site Preparation
The DECarray cabinet is intended for installation in a Class A computer
room environment. Before installing the DECarray, make sure the following
conditions are met:
• The DECarray cabinet requires 3-phase ac power. Each phase draws up to
7.2 amperes in a fully configured array.
• Adequate space is provided around the DECarray cabinet for opening the
front and rear doors, for accessing cables, and for adequate airflow.
• The installation site floor can safely bear the weight of the DECarray
cabinet. The DECarray cabinet with power controller weighs 180 kilograms
(396 pounds); a fully configured DECarray weighs 454 kilograms (1000
pounds).
• The system’s configuration sheet has been correctly filled out and is
up-to-date. Blank system configuration sheets can be found in Appendix E.
• An adequate number of DSSI adapter modules are installed in the system
to support all the DSSI devices in the DECarray.
• The correct NEMA plug or plugs are available (Figure 2–1).
