Introduction
This chapter describes environmental specifications, site preparation procedures, and procedures
for unpacking and inspecting the supplied materials for the HP 1000 A990 Computer (HP 2959A)
and the HP 1000 A990 System (HP 2999A). The HP 2959A Computer product consists of an
A990 CPU Card in a 20-s10t card cage with power supply, and appropriate manuals. The HP
2999A System Processor Unit (SPU) consists of an A990 CPU card in a 20-s10t card cage with
power supply, HP-IB or SCSI Interface, RTE-A Primary System software, diagnostic software,
appropriate manuals, and on-site installation assistance and checkout by a Hewlett-Packard
Service Engineer.
Site Preparation
When you prepare the site for the computer or system, be sure you include provisions for
environmental considerations, power requirements, and type of mounting. The computer or
system operates at a nominal 115 Vac or, optionally, at 230 Vac. The system may be table
mounted or rack mounted.
Environmental Considerations
Table 1-1 describes the environmental requirements for the A990. When you set up your
computer or system, be sure you take into account environmental requirements or limitations
imposed by all peripheral devices and components in the same location.
Power Requirements
The HP 2959A and HP 2999A are shipped with the power supply configured for a single-phase
power source of 86 Vac to 138 Vac (standard) or 178 Vac to 276 Vac (option 015).
Maximum power consumption of the HP 2959/99A is 750 watts (1400 VA). Refer to Chapter 3 for
information on changing the power supply line configuration from 115 Vac to 230 Vac operation.
For the protection of your operating and service people, various safety codes require you to
ground the instrument chassis, panels, and housing. You can satisfy this requirement by
providing a grounded three-wire female power outlet at the computer location. This outlet should
be checked by a qualified electrician to ensure that it furnishes the required voltage and current.
