Installing and Removing an S-AC-PS Power Supply
Enterasys S-Series S8 Chassis Hardware Installation Guide 3-15
Be
aware
that
when
you
receive
your
S8
chassis,
a
coverplate
will
be
in
place
over
all
power
supply
slots
except
PS1.
Power Supply Planning
Although
each
power
supply
requires
its
own
circuit,
when
planning
the
S8
chassis
power
budget
you
have
the
option
of
drawing
from
one
or
more
sources
by
either
the
N
+
1
or
1
+
1
method,
respectively.
The
N
+
1
method
protects
the
S8
chassis
against
the
failure
of
a
single
power
supply
although
not
against
an
outage
by
that
source.
In
a
scheme
where
three
modules
are
installed,
you
can
assign
all
three
modules
to
one
source.
This
is
the
most
common
approach
to
power
supply
planning.
Alternately,
the
1
+
1
method
has
the
advantage
of
protecting
the
S8
chassis
against
an
outage
by
one
of
the
power
sources
as
well
as
the
failure
of
one
or
as
many
as
half
of
your
power
supplies.
However,
this
method
requires
either
a
backup
battery
or
another
power
source
separate
from
the
first
power
source.
The
number
of
power
supplies
required
in
an
S8
chassis
is
determined
by
the
number
and
types
of
modules
installed
in
the
chassis.
Unpacking the S-AC-PS Power Supplies
The
S
‐
AC
‐
PS
power
supply
modules
are
shipped
in
boxes
separate
from
the
S
‐
Series
chassis.
To
unpack
a
power
supply:
1.
Unpack
the
power
supply
by
removing
it
from
the
shipping
box
and
sliding
the
two
foam
end
caps
off
the
unit.
Save
the
shipping
box
and
materials
in
the
event
the
unit
must
be
reshipped.
2.
Verify
the
contents
of
the
box
using
as
appropriate.
3.
Remove
the
power
supply
from
its
protective
plastic
bag.
4.
Examine
the
power
supply
carefully,
checking
for
damage.
If
any
damage
is
noted,
DO
NOT
install
the
power
supply.
Contact
Enterasys
Networks
immediately.
Refer

details.
