Two
power
supply
modules
are
required
for
redundancy.
Each
power
supply
can
be
connected
to
a
separate
circuit
to
mitigate
the
risk
of
down
‐
time
during
a
localized
power
failure.
When
used
in
a
redundant
configuration,
the
dual
power
supplies
have
a
load
‐
sharing
capability
that
enables
each
power
supply
to
operate
at
approximately
50
percent
of
full
load.
Using
redundant
power
can
minimize
the
power
disruption
during
a
power
supply
failure
and
extend
the
expected
lifetime
of
each
power
supply
by
operating
normally
in
a
conservative
power
mode.
For
proper
airflow
when
operating
the
switch
with
only
one
power
supply
module,
the
empty
power
supply
bay
must
be
protected
by
a
blank
cover
module.
