2.2 Before Installing the Main Unit
Be sure that you understand the system configuration and have acquired all the requisite installation information before
installing the main unit.
For a system overview and details on the system configuration, see the PRIMEQUEST2000 Series General Description
(C122-B025EN). For details on the installation prerequisites, see the PRIMEQUEST2000 Series Hardware Installation
Manual (C122-H007EN).
2.3 Checking Environmental Conditions
This section describes the environmental conditions for main unit installation.
The conditions of the main unit operating environment depend on the altitude of the installation site.
For details on the environmental conditions of the PRIMEQUEST2000 series, see 1.3 Installation Specifications in the
PRIMEQUEST2000 Series Hardware Installation Manual (C122-H007EN).
For details on the recommended temperature and humidity of the computer room, see the SPARC
Enterprise/PRIMEQUEST Common Installation Planning Manual (C120-H007EN).
2.4 Preparing the Power Supply Equipment
This section describes the electrical specifications, facility power requirements, and grounding for the
PRIMEQUEST2000 series. To prevent accidents, confirm that the power supply equipment can supply enough power to
the system. Electricianing and installation work shall conform to local ordinances and local and national government
regulations.
For details on the power supply equipment, see the SPARC Enterprise/PRIMEQUEST Common Installation Planning
Manual (C120-H007EN).
