Power Supply Replacement
To
reduce
network
downtime,
a
power
supply
may
be
hot
swapped.
When
multiple
power
supplies
are
installed,
this
allows
the
removal
of
one
power
supply
without
powering
down
the
chassis
and
interrupting
network
traffic.
The S-FAN Chassis Cooling System
The
S8
chassis
features
removable
fan
trays
that
are
accessible
from
the
front
of
the
chassis.
These
fan
trays
are
hot
swappable,
which
allow
them
to
be
replaced
without
powering
down
the
chassis.
The
fan
trays
have
one
LED
located
on
the
front
of
the
unit.
This
LED
indicates
the
status
of
the
fan
trays
(normal/fault/not
installed).
Refer
to
for
a
full
description
of
the
fan
tray
LED
states.
Standalone or Rack Mountable Chassis
The
S8
chassis
can
be
installed
as
a
freestanding
unit
on
a
shelf
or
table.
The
S8
chassis
can
also
be
mounted
into
a
standard
48.26
‐
centimeter
(19
‐
inch)
equipment
rack.
In
a
rack
installation,
the
S8
chassis
can
be
either
front
mounted
or
mid
‐
mounted.
To
mid
‐
mount
an
S8
chassis,
you
must
use
the
S
‐
Series
mid
‐
mount
brackets
that
are
available
separately.
Refer
to
for
requirements
on
ventilation
and
cooling.
RJ45 COM Ports
In
the
S8
chassis,
the
RJ45
COM
ports
are
designed
for
accessing
specific
I/O
fabric
modules.
For
a
particular
COM
port
to
be
functional,
an
I/O
fabric
module
must
be
present
in
the
corresponding
slot.
In
the
S8
chassis,
the
COM
ports
correspond
to
slots
4,
5,
and
6.
USB Ports
The
USB
ports
on
the
S8
chassis
allow
you
to
use
a
USB
drive
to
upgrade
the
chassis
and
upload
and
download
files,
such
as
configuration
files
and
firmware
images.
A
USB
port,
however,
functions
only
if
an
I/O
fabric
module
is
present
in
the
corresponding
slot.
In
the
S8
chassis,
the
USB
ports
correspond
to
slots
4,
5,
and
6.
