Pre-installation
check-list
1)
The
System
2800
can
be
ordered
for
either
110
or
220
volt
power
sources.
Make
sure
that
the
system
to
be
installed
has
the
proper
power
supply
for
the
power
supply
in
your
region.
2)
It
is
recommended,
but
not
required,
that
the
power
line
to
which
the
computer
is
connected
be
a
"dedicated"
power
line;
that
is,
the
line
CClIT'eS
directly
from
the
building's
power
source,
no
other
devices
except
another
System
2800
making
use
of
it,
and
that
it
is
well
grounded.
The
intent
in
this
recanrnendation
is
to
eliminate
electronic
"noise"
on
the
power
line
which
can
effect
the
reliability
of
the
system,
and
to
avoid
the
loss
of
data
if
the
circuit
breaker
is
tripped
because
another
device
short
circuits
or
too
many
devices
are
connected.
It
is
particularly
critical
that
heavy
machinery
not
be
connected
to
the
same power
line.
3) Do
not
install
more
than
two
system
2800's
per
20A
circuit.
4)
Extension
cords
are
not
recommended.
5)
Special
air-conditioning
and
raised
floors
are
not
required
for
a
system
2800.
It
will
function
in
a
normal
office
environment.
6)
I:b
not
install
a
System
2800
in
abnormally
dusty
or
dirty
environments,
due
to
the
effect
on
the
disk
drives
and
diskettes.
7)
Make
sure
there
is
adequate
area
for
all
equipment,
and
there
is
adequate
desk
space
next
to
the
console.
The
console
must
be
low
enough
for
comfortable
typing.
There
must
be
some
space
left
to
the
rear
of
the
console
for
adequate
ventilation.
8)
Make
sure
the
console
is
not
directly
oPIX'si
te
a
bright
open
window,
as
that
will
create
a
glare
on
the
screen.
9)
If
the
carpet
in
the
computer
area
is
a
shag
or
thick
carpet,
and
if
there
is
a
lot
of
foot
traffic
near
the
computer,
or
if
the
operator
I s
chair
has
rolling
casters,
there
may
be
a
build
up
of
static
in
the
operator
and
people
passing
by
that
can
discharge
into
the
system
and
cause
the
system
to
malfunction.
If
you
anticipate
or
experience
this
problem,
spray
the
carpet
with
anti-static
spray
available
in
many
electronic
supply
and
carpet
distributors.
If
the
system
is
still
affected
by
static,
we
recanrnend
the
purchase
of
a
3M
anti-static
mat
to
be
placed
on
the
floor
in
the
computer
area.
