Chapter 3. Physical  specifications
This section lists the physical specifications for the NetVista computer.  The NetVista 
small form factor desktop model has two 32-bit PCI expansion slots and three drive 
bays.  The NetVista desktop model computer has three 32-bit PCI expansion slots, 
one AGP slot (some models only), and four drive bays.
Note: The computer is classified as a Class A or Class B digital device.  See the 
NetVista User Guide
 for further information about this classification.

model
Dimensions 
Height:  87 mm (3.43 in.)
Width:  345 mm (13.6 in.)
Depth:  360 mm (14.2 in.)
 Weight 
Minimum configuration as shipped:  8.2 kg (18 lb)
Maximum configuration:  8.6 kg (19 lb)
 Environment 
Air temperature:   
System on:  10° to 35°C  (50° to 95° F)
System off:  10° to 43° C (50° to 110° F)
Maximum altitude:  2134 m (7000 ft)   
Note: The maximum altitude, 2134 m (7000 ft), 
is the maximum altitude at which the 
specified air temperatures apply.  At 
higher altitudes, the maximum air 
temperatures are lower than those 
specified.
 
Humidity:     
System on:  8% to 80%
System off:  8% to 80%
 Electrical input 
Input voltage:   
Minimum:  90 V ac
Maximum:  265 V ac
Input frequency range:  47–63 Hz
Input kilovolt-amperes (kVA) (approximate):   
Minimum configuration as shipped:  0.08 kVA
Maximum configuration:  0.16 kVA
 
Note: Power consumption and heat output vary 
depending on the number and type of optional 
features installed and the power-management 
optional features in use.
Heat output (approximate) in British thermal units (Btu) 
per hour:   
Minimum configuration:  205 Btu/hr (60 watts)
Maximum configuration:  375 Btu/hr (110 watts)
 Airflow 
Approximately 0.25 cubic meters per minute (9 cubic 
feet per minute) maximum
 Acoustical noise-emission values 
Average sound-pressure levels:   
At operator position:   
Idle:  38 dBA
Operating:  43 dBA
At bystander position - 1 meter (3.3 ft):   
Idle:  33 dBA
Operating:  37 dBA
Declared (upper limit) sound-power levels:   
Idle:  4.8 bels
Operating:  5.1 bels
 
Note: These levels were measured in controlled 
acoustical environments according to the 
procedures specified by the American 
National Standards Institute (ANSI) S12.10 
and ISO 7779 and are reported in accordance 
with ISO 9296.  Actual sound-pressure levels 
in a given location might exceed the average 
values stated because of room reflections and 
other nearby noise sources.  The declared 
sound-power levels indicate an upper limit, 
below which a large number of computers will 
operate.
