Power
Management
Mode
There
are
2
modes
for
configuring
when
to
shut
down
the
ports:
1.
Actual
Consumption:
In
this
mode
the
ports
are
shut
down
when
the
actual
power
consumption
for
all
ports
exceeds
the
amount
of
power
that
the
power
supply
can
deliver
or
if
the
actual
power
consumption
for
a
given
port
exceeds
the
reserved
power
for
that
port.
The
ports
are
shut
down
according
to
the
ports
priority.
If
two
ports
have
the
same
priority
the
port
with
the
highest
port
number
is
shut
down.
2.
Reserved
Power:
In
this
mode
the
ports
are
shut
down
when
total
reserved
powered
exceeds
the
amount
of
power
that
the
power
supply
can
deliver.
In
this
mode
the
port
power
is
not
turned
on
if
the
PD
requests
more
power
than
available
from
the
power
supply.
Power
Supply
Configuration
Primary
and
Backup
Power
Source
Some
switches
support
having
two
PoE
power
supplies.
One
is
used
as
primary
power
source,
and
one
as
backup
power
source.
If
the
switch
doesn't
support
backup
power
supply
only
the
primary
power
supply
settings
will
be
shown.
In
case
that
the
primary
power
source
fails
the
backup
power
source
will
take
over.
For
being
able
to
determine
the
amount
of
power
the
PD
may
use,
it
must
be
defined
what
amount
of
power
the
primary
and
backup
power
sources
can
deliver.
Valid
values
are
in
the
range
0
to
2000
Watts.

This
is
the
logical
port
number
for
this
row.
Ports
that
are
not
PoE
‐
capable
are
grayed
out
and
thus
impossible
to
configure
PoE
for.
