3 • Installation and Power-Up
3.1 Installation
SBC330
boards
should
only
be
installed
into
3U
VPX
backplanes.
With
the
VPX
connector
standard,
great
care
should
be
exercised
in
installation
and
removal
of
all
daughter
boards
into
the
backplanes.
The
insertion
forces
are
significant.
CAUTION
The SBC330 has been specifically designed for use with 3U VPX backplanes and is
not
compatible
with 6U backplanes. Plugging the SBC330 into a 6U backplane may cause permanent component
damage.
The
SBC330
is
normally
supplied
with
round
‐
hole
VPX
guides
that
allow
it
to
be
plugged
into
any
VPX
backplane
slot.
Many
new
‐
generation
backplanes
have
some
tracking
within
the
backplane
PCB
for
fast
I/O
and
so
may
also
have
tracking
for
external
I/O,
which
operates
at
high
voltages.
Ensure
that
the
slot
into
which
the
SBC330
board
is
plugged
is
intended
for
use
by
the
SBC330
and
does
not
have
any
high
voltage
I/O
inputs
on
the
VPX
connectors.
TIP
GEIP supply universal backplanes that allow modules to be plugged into any slot. All I/O
connections are made with Rear Transition Modules and high specification cabling.
The
SBC330
is
electrically
compatible
with
the
pin
listings
in
Chapter
9 •
.
Carry
out
all
installation
with
the
power
and
data
cables
fully
disconnected.
NOTE
Only plug SBC330 boards into compatible system backplane slots.
Air
‐
cooled
versions
of
the
SBC330
have
an
injector/ejector
handle
to
ensure
that
the
backplane
connectors
mate
properly
with
the
backplane.
The
best
way
to
install
a
build
level
1
to
3
SBC330
into
a
convection
cooled
rack
is
to
use
the
leverage
of
the
purpose
‐
designed
handle.
The
captive
screws
at
the
top
and
bottom
of
the
front
panel
allow
the
board
to
be
tightly
secured
in
position,
which
provides
continuity
with
the
chassis
ground
of
the
system.
Build
level
4
and
5
boards
need
to
be
inserted
with
the
wedge
‐
locks
wound
back
only
so
far
as
not
to
contact
the
sides.
When
tightening
the
wedge
‐
locks,
take
care
that
the
contacting
beams
have
not
rotated
by
90
degrees.
This
possibility
has
been
virtually
eliminated
on
later
designed
heatsinks,
but
may
still
be
possible
(rotated
wedge
‐
locks
wedge
against
the
wrong
surface
and
can
crack
when
tightened.)
Correct
adjustment
requires
a
calibrated
torque
wrench
with
a
hexagonal
head
of
size
3/32”
(2.38
mm),
set
to
between
0.6
and
0.8
Nm.
In
an
air
‐
cooled
development
enclosure,
when
taking
I/O
connections
from
the
backplane
connectors,
use
of
the
GEIP
SBC330RTM
ensures
optimum
operation
of
the
SBC330
with
regard
to
EMI.
