There
are
three
modes
for
configuring
how
the
ports/PDs
may
reserve
power.
1.
Allocated
mode:
In
this
mode
the
user
allocates
the
amount
of
power
that
each
port
may
reserve.
The
allocated/reserved
power
for
each
port/PD
is
specified
in
the
Maximum
Power
fields.
2.
Class
mode:
In
this
mode
each
port
automatically
determines
how
much
power
to
reserve
according
to
the
class
the
connected
PD
belongs
to,
and
reserves
the
power
accordingly.
Four
different
port
classes
exist
and
one
for
4,
7,
15.4
or
30
Watts.
In
this
mode
the
Maximum
Power
fields
have
no
effect.
3.
LLDP
‐
MED
mode:
This
mode
is
similar
to
the
Class
mode
expect
that
each
port
determine
the
amount
power
it
reserves
by
exchanging
PoE
information
using
the
LLDP
protocol
and
reserves
power
accordingly.
If
no
LLDP
information
is
available
for
a
port,
the
port
will
reserve
power
using
the
class
mode.
In
this
mode
the
Maximum
Power
fields
have
no
effect
For
all
modes:
If
a
port
uses
more
power
than
the
reserved
power
for
the
port,
the
port
is
shut
down.
