===========================================================================
ENVIRONMENTAL RUGGEDNESS
The Model A2094A is designed for use in an environment which involves
moderately high and low temperatures, humidity variations and occasional
vibration. Samples of the Model A2094A, representative of customer
shippable units, have been tested prior to the release of the units to
manufacturing. The products were evaluated in a variety of configurations
for each environmental test, so that worst case situations for all environ-
ments were tested. The numbers shown under "Test Results" are accurate as
of the date of this publication. Presentation of the test data does not
imply a guarantee of performance; a brief description of testing and
results for the monitor, follow in the section entitled "Test Summary
and Test Results"
In addition to these tests the Model A2094A was subjected to more severe
tests during the product development stage. These development tests were
designed to cause product failure so that the failure mechanisms are
understood and eliminated when possible.

RELIABILITY
Annualized Failure Rate (AFR) = 6% Yr (Model A2094A with __ Mbytes RAM).
The estimated AFR is based on parts count and the failure rates of
those parts in similar products. The AFR is estimated from the sum of
the failure rates of the component assemblies.
Mean Time Between Failure (MTBF) = 16.6 years (Model A2094A with __ Mbytes RAM),
where MTBF = 1/AFR. A key assumption is that AFR is constant beyond the early
life of the product and before long-term wearout.
Projected Failure Rate is the mature AFR, estimated from the failure rates
of the components of the product. The "Estimated Long-Term Annualized
Failure Rate" is a future projection of an average realistic failure
rate beyond the typical infant failure period which occurs in the first
few months of use and before long-term wearout which occurs after many
years of use. This product assumes an 8000 hour usage year, which is
91% duty. Actual customer experience may vary slightly.
***************************************************************************
QUALITY FLOWCHART
The Model A2094A is designed to comply with all necessary regulatory
agency requirements for safety and environmental standards, and
Hewlett-Packard has ensured that additional environmental ruggedness
specification and reliability requirements are designed in. Finally, great
care is taken to consistently manufacture these features into each product
and operate an audit program which maintains these features. Here is a
flowchart of the major quality checkpoints in the manufacturing process:
MANUFACTURING PROCESS
Incoming Quality Assurance
- Inspect mechanical parts for which we have no historical data. Provid
feedback to vendors. (Electronic components with less than 100 parts
per million failure rate are not inspected).
- 100% of new parts tested.
Clean and Inspect
- Soldered PC boards with active components cleaned and inspected.
- 100% of boards sensitive to heat or water tested.
Functional Board Test
- PC board tested with active components on HP 3065. Processor board
functionally tested with throughput tester.
- 100% of boards tested.
Unit Aging and Test
- Temperature cycled: 0 degrees C to + 50 degrees C, 8 cycles, approx. 6
minutes per cycle while functionally tested. Power cycled 16 times, o
at each extreme; others random.
- 100% of units tested.
Turn on and Final Test
- Assembled product is powered up and tested with extensive software tes
- 100% of units tested.

SYSTEM HARDWARE AUDITS
Periodic hardware audits of HP Model A2094A bundled systems are scheduled to
be conducted. Audits are performed to assist Exeter Computer Manu-
facturing Operation in verifying continuing product quality. The audit
scope is defined in HP System Audit Flowchart A-5959-6347. An audit
procedure specification for the Model A2094A which defines actual audit
tests and test limits will be used. The audit test includes the following
categories. Safety, EMC, Software, Environmental and Workmanship.
Audit Reports are distributed monthly to key partners. These reports
describe the audit findings. A Corrective Action Request (C.A.R.) is also
written and distributed to appropriate persons.
