1.6 Installation and Power Up/Reset
1.6.1 Board Keying
The
6U
VPX
backplane
specification
requires
all
backplane
slots
to
have
three
guide
pins:
one
above
the
P0
connector,
one
below
the
P2
connector,
and
one
below
the
P6
connector.
In
addition
to
providing
correct
alignment,
these
pins
are
keyed
to
prevent
cards
from
being
inserted
into
incorrect
backplane
slot(s)
to
avoid
electrical
incompatibility.
The
board
has
receptacles
for
these
guide
pins
(see
the
Connectors
section).
By
default,
these
are
not
keyed.
Please
contact
the
factory
to
discuss
keying
requirements.
1.6.2 Board Installation Notes
•
Keying
may
dictate
the
backplane
slot(s)
into
which
the
board
can
be
inserted.
•
Air
‐
cooled
versions
have
an
injector/ejector
handle
to
ensure
that
the
back
‐
plane
connectors
mate
properly
with
the
backplane.
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.
•
Conduction
‐
cooled
versions
have
screw
‐
driven
wedge
locks
at
the
top
and
bottom
of
the
board
to
provide
the
necessary
mechanical/thermal
interface.
Correct
adjustment
requires
a
calibrated
torque
wrench
with
a
hexagonal
head
of
size
3/32
ʺ
(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
GE’s
I/O
modules
(or
some
equivalent
sys
‐
tem)
ensures
optimum
operation
with
regard
to
EMI.
1.6.3 Power Requirements
The
SBC622
utilizes
the
VS1
and
VS3
power
supplies
from
the
VPX
backplane.
The
SBC622
requires
up
to
16
W
from
VS1
(@12V),
and
38
W
from
VS3
(@5
V)
1
.
The
SBC622
does
not
connect
to
the
VS2
power
pins.
Live
insertion
as
defined
in
VITA
1.4
is
not
supported
on
SBC622.
•
The
VS1
and
VS3
rails
are
used
for
SBC622
circuits
and
at
the
PMC
site.
The
VCC_12V_AUX
and
VCC_
‐
12V_AUX
rails
are
only
used
at
the
PMC
sites.
Aggregate
power
load
is
expected
to
be
60
W
maximum
for
the
main
SBC622
board,
plus
a
maximum
of
7.5
W
for
each
of
the
PMC
sites.
Additional
current
loading
may
be
supported
at
the
PMC
site
to
the
limit
of
the
backplane
and
PMC
site
connector
capacities.
