Removing
and
replacing
a
power
supply
or
filler
panel
Use
this
procedure
to
remove
and
replace
a
power
supply.
The
switch
can
continue
to
operate
during
the
replacement
if
at
least
one
power
supply
continues
operating
for
every
four
16–port
cards
that
are
installed.
You
need
a
minimum
of
two
power
supplies.
Note:
You
do
not
need
to
notify
the
switch
of
a
hot-swap
request
before
you
remove
a
power
supply.
Power
supply
filler
panels
are
not
required
to
ensure
correct
air
flow.
The
left
power
connector
provides
power
to
the
power
supplies
in
slots
1
and
3.
The
right
power
connector
provides
power
to
the
power
supplies
in
slots
2
and
4.
The
power

slots
are
color-coded
to

If
only
two
power
supplies
are
installed
and
they
are
both
installed
in
slots
corresponding
to
the
same
power
cable,
unplugging
a

power
cable
will
power
down
the
entire
chassis.
Attention:
If
adequate
power
is
abruptly
lost,
such
as
through
removal
of
a
power
supply,
the
entire

is
powered
down.
The
power
off
order
that
the

command
designates
is
not
followed.
Attention:
Disassembling
any
part
of
the
