installed
either
as
a
free-standing
unit,
or
installed
in
an
EIA
cabinet,
using
an
optional
slide-rail
rack
mount
kit.
When
mounting
into
a
slide-rail
rack,
you
can
mount
the
chassis
to
slide
from
either
the
port
side
or
the
nonport
side.
Electrical
considerations
To
install
and
operate
the
switch
successfully,
ensure
the
following:
v
The
primary
outlet
is
correctly
wired,
protected
by
a
circuit
breaker,
and
grounded
in
accordance
with
local
electrical
codes.
v
The
supply
circuit,
line
fusing,
and
wire
size
are
adequate,
as
specified
by
the
electrical
rating
on
the
switch
nameplate.
v
The
power
supply
standards
provided
in
“Power
supply
specifications”
on
page
38
are
met.
Environment
considerations
For
successful
installation
and
operation
of
the
switch,
ensure
that
the
following
environmental
requirements
are
met:
v
At
a
minimum,
adequate
cooling
requires
that
you
install
the
switch
with
the
nonport
side,
which
contains
the
air
intake
vents,
facing
the
cool-air
aisle.
v
All
equipment
in
the
rack
should
force
air
in
the
same
direction
to
avoid
intaking
exhaust
air.
v
A
minimum
air
flow
of
47
cubic
feet/minute
(79.8
cubic
meters/hour)
available
on
the
nonport
side
of
the
switch.
v
The
ambient
air
temperature
does
not
exceed
40°
C
(104°
F)
while
the
switch
is
operating.
Cabinet
considerations
Attention:
See
“Rack
safety”
on
page
xiv
for
danger
and
caution
notices
related
to
product
installations
in
racks
or
cabinets.
For
successful
installation
and
operation
of
the
switch
in
a
cabinet,
ensure
that
the
following
cabinet
requirements
are
met:
v
The
cabinet
must
be
a
standard
EIA
cabinet.
v
Plan
a
cabinet
space
that
is
1
rack
unit
4.45
cm
(1.75
in)
high,
48.3
cm
(19
in.)
wide.
v
Ground
all
equipment
in
the
cabinet
through
a
reliable
branch
circuit
connection
and
maintain
ground
at
all
times.
Do
not
rely
on
a
secondary
connection
to
a
branch
circuit,
such
as
a
power
strip.
v
Ensure
that
airflow
and
temperature
requirements
are
met
on
an
ongoing
basis,
particularly
if
the
switch
is
installed
in
a
closed
or
multicabinet
assembly.
v
Verify
that
the
additional
weight
of
the
switch
does
not
exceed
the
cabinet’s
weight
limits
or
unbalance
the
cabinet
in
any
way.
v
Secure
the
cabinet
to
ensure
stability
in
case
of
unexpected
movement,
such
as
an
earthquake.
