DECsystem 5900 Site Preparation

This document provides crucial information for preparing a computer room for the DECsystem 5900 server, intended to be used in conjunction with the Site Environmental Preparation Guide. It details the server's physical specifications, including its operational weight (440 kg/970 lb) and dimensions (170 cm H x 61 cm W x 86.4 cm D), alongside shipping weight (485 kg/1070 lb) and measurements.

The document outlines environmental requirements such as an operating temperature range of 0° to 32° C (32° to 90° F), humidity between 20% and 80%, and an altitude limit of 3,000 m (10,000 ft). It specifies front intake and back exhaust airflow, a maximum heat dissipation of 1560 Watts (5325 Btu/h), and required service clearances (90 cm/36 in front, 56 cm/22 in back).

Furthermore, it covers power requirements for both 120 Vac and 230 Vac configurations, including frequency range (47-63 Hz), nominal voltage, maximum power consumption (1560 Watts), and start-up currents (30 rms Amps for 120V, 16 rms Amps for 230V). A table also lists specific power cable and plug numbers for various international 230 Vac installations.
