4.2 PCI Bus Master

4.2.1 PCI Slot Configuration Guidelines

! I/O riser 0 must be installed.
! The standard I/O module is always installed in riser 0-slot 1.
! Install high-powered modules in slots with one inch module pitch (all slots

6, riser 1-slot 5, and riser 1-slot 6).

! Install high-performance adapters across multiple bus/hose segments to get maximum performance
! VGA graphics options must be installed in riser 0-slot 2 or riser 0-slot 3.

CAUTION:

standard I/O module.

Installing a full-length module next to the standard I/O module requires extra care due to cabling on the

except

riser 0-slot 5, riser 0-slot

4.3 Compaq AlphaServer GS320 Powered Subrack

Figure 9 Compaq AlphaServer GS320 Powered Subrack

The power subrack holds three power supplies that power a system box containing two QBBs.

14

4.3.1.1 Power Supply Installation Or der

Loads must be properly distributed across the three phases to avoid nuisance tripping of circuit breakers. Therefore,
placement of the third, redundant power supply is important. Figure 12 provides a chart showing the recommended
placement.

Two power supplies are needed to power one system box, the H-switch, OCP, and blower. The third power supply
is redundant. When three power supplies are in a subrack, one may be hot swapped.

8.3 Voltage Transients

Power line transients should be no greater in amplitude than the value of the nominal AC RMS voltage. This
limitation applies to common and transverse mode transients of positive or negative polarity as they are imposed in
the AC sine wave.

8.4 Voltage Harmonic Distortion

The power source voltage total harmonic distortion should not exceed 5% with any single harmonic not exceeding
3% of the fundamental frequency.

8.9 Magnetic Fields

Most equipment, excluding monitors and some disk and tape products at power line frequencies, can operate
properly up to the AC magnetic field flux density limits specified below. Above these limits, the operation of some
equipment may be impaired.

Frequency (Hertz) Maximum field (Gauss)

50 10.0

500 2.0

1000 1.0

10000 0.1

500000 0.002

For high resolution monitors using refresh rates different from the power line frequency, the maximum AC magnetic
field flux density at power line frequencies is 7.07 mGauss RMS (20 mGauss peak-to-peak). For low resolution
monitors, the maximum AC magnetic field flux density at power line frequencies varies with the product, but is
always greater than 7.07 mGauss RMS. The maximum DC magnetic field flux density limit up to which most
monitors operate properly is approximately 2.0 Gauss.

For some disk and tape drive products, the maximum Dc and AC magnetic field flux density specified at power line
frequencies is 3.0 Gauss. Other disk and tape drive products can withstand higher magnetic field flux densities

Avoid storage of media in Ac or DC magnetic fields. In unavoidable locations, the media should only be subjected
to AC magnetic field flux densities up to a maximum of 3.0 Gauss.

8.10 Electric Fields

Maximum of 2 volts/meter cumulative total for radiated fields from 10 kHz to 1 GHz.
Ensure that not more than 1 volt RMS is present on the AC connection points to the computer system from 10 kHz
to 30 MHz. Measure between frame of the equipment and all phase, neutral, and grounding connections at the
power receptacle(s).

8.11 Operating Environment

Temperature range: 21oC +3oC (70oF+5oF)
Temperature rate of change: Maximum of 3oC/hour (5.4oF/hour)
Temperature adjustment for altitude: Reduce the operating temperature by 1.8oC/1000 meters (1oF/1000

feet)
Relative humidity range: 50% RH+10% (no condensation)
Relative humidity rate of change: Maximum of 6%/hour

8.12 Shipping And Storage In Shipment Containers For Less Than 60 Days

Temperature range: -40o to 66oC (-40o to 151oF)
Temperature rate of change: Maximum of 20oC/hour (36oF/hour)

Relative humidity range: 0 to 95% RH (no condensation)

8.13 Storage In Shipment Containers For More Than 60 Days

Temperature range: 5o to 50oC (40o to 122oF)
Temperature rate of change: Maximum of 11oC/hour (20oF/hour)

Relative humidity range: 10 to 95% RH (no condensation)
Wet bulb temperature: Maximum of 32oC (90oF)

8.14 Altitude

Most equipment has been normally tested on a short-term basis for performance, up to an altitude of 2.4 kilometers
(8000 feet). Above this altitude, the operation of equipment may be impaired.

8.15 Airflow Rate Range

266-314 m3/h-kilowatts or 550-650 cfm/ton at the air-conditioner output

8.16 Vibration

Most equipment has been normally tested on a short-term basis for performance up to the vibration limits specified
below. Above these limits or with a continuous vibration level, the operation of equipment may be impaired

Frequency (Hertz) Amplitude
5 - 22 0.254 millimeters (0.010 inches) double amplitude
22-500 0.25 g peak
