Attention:
Both
support
rails
are
shipped
with
three
screws
and
spacers,
called
alignment
pins
,
already
installed
at
the
front
of
each
rail.
They
have
been
inserted
in
the
front
of
each
support
rail
as
guides
to
indicate
where
not
to
use
M6
screws
when
you
attach
the
front
of
the
support
rail
to
the
rack.
See
Depending
on
which
type
of
rack
mounting
flange
is
present
on
your
rack,
you
might
have
to
remove
some
or
all
of
the
alignment
pins.
For
example,
if
the
rack
in
which
you
are
installing
the
support
rails
has
round
holes,
you
will
need
to
remove
the
spacers
from
the
top
and
bottom
alignment
pins
so
that
the
rail
sits
flush
with
the
rack.

The
rack-mounted
unit
is
three
EIA
units
high.
Decide
accordingly
where
you
are
going
to
install
the
support
rails.
Attention:
Use
the
rack
mounting
template
provided
in
and
to
locate
the
proper
rack
mounting
holes
for
installing
the
support
rails
into
the
rack.
Note
the
following
considerations
before
you
choose
where
to
install
the
rails:
v
If
you
are
installing
the
EXP100
into
an
empty
rack,
install
it
into
the
lowest
available
position
so
that
the
rack
does
not
become
unstable.
v
If
you
are
installing
more
than
one
EXP100
in
the
rack,
start
at
the
lowest
available
position,
and
work
upward.
v
If
appropriate,
allow
for
possible
later
installation
of
other
units.
v
If
necessary,
remove
the
rack
power
distribution
unit
before
you
install
the
support
rails.
v
For
procedures
and
more
information,
refer
to
the
installation
and
service
guide,
or
equivalent,
for
the
rack.
