Warnings, cautions
and
notes are used
through
out
this
document
to
alert
the
user
to
conditions
of inlportance.
They
are used as follows:
• WARNINGS relate
to
activity which, if
not
properly performed, could result in injury
to
personnel
or
loss
of
life.
• CAUTIONS relate
to
activity, which if
not
properly performed, could result in
damage
to
or
destruction
of
equipment.
In
this
case, injury
to
personnel
is
typically
not
a concern.
• NOTES provide information
that
will help
understand
situations
and
better
prepare
peo-
ple in accomplishing
the
job.
Examples:
WARNING
The power supply presents a hazard to personnel when it is energized
and exposed. Extreme care must be taken when connecting a voltmeter
probes to the test points. Accidental bridging
of
the
+5
volt supply
to ground
by
rings or other jewelry can cause severe personal injury.
De-energize the equipment
by
turning off the unit and removing the
power cord before connecting or removing test probes.
CAUTION
The electronic assemblies in these products are susceptible to damage
by
electro-static discharge. Extreme care must be used when handling
printed circuit assemblies. Handle printed circuit assemblies only when
grounded to an anti-static workstation.
NOTE
Hewlett-Packard
supports
field repair only
to
the
assembly level.
The
fault
is
diagnosed
to
the
assembly
that
is
causing
the
problem.
That
assembly
is
then
replaced with a new
or
rebuilt one.

Information
Introduction
Series 300 Computers are modular cOInputers.
The
HP
98568A Bus Expander permits
an
additional eight accessory slots
to
be used in
the
system.
With a low
entry cost
and
a wide
range of accessories
and
interfaces 1 these computers provide technical-professional workstations
that
maximize productivity. Processing
is
accomplished by
the
MC68010 or MC68020 CPUs
enabling high-speed
data
access
and
manipulation.
Available operating systems for these computers include
BASIC, Pascal,
and
HP-UX. Several
application programs are also available
that
run
on any of these operating systems or on a subset
of one of them.

Hewlett

Support
Hewlett-Packard provides service
support
in
three
ways:
• On-Site Repair.
• Service
Center
Repair.
•
Customer
Repair.
Each of these
are
explained in
the
sections below.
On-Site
Repair
For On-Site Repair,
an
HP
Customer
Engineer goes
to
the
customers site, troubleshoots,
and
repairs
the
hardware
to
the
assembly level.
The
defective assembly is replaced
with
a new
or
rebuilt assembly.
This
service
is
available
through
a service
contract
or
a time-and-materials
basis.
Hewlett-Packard
Service
Center
Repair
The
customer
returns
the
defective
product
to
the
nearest
HP
Repair Center. An
HP
Customer
Engineer repairs
the
product
to
the
assembly level in
the
same
manner
as On-Site Repair.
Upon
being repaired,
the
product
is
returned
to
the
customer.
