CP
blades
and
16-port
blades
The
M12
and
M14
switch
chassis
contain
two
control
processor
(CP)
blades
and
up
to
eight
16–port
blades.
The
features
of
these
two
types
of
blades
are
described
in
“CP
blade
assembly”
on
page
14
and
“Switch
blade
assembly”
on
page
16.
With
up
to
eight
hot-swappable
16–port
switch
blade
assemblies,
the
M12
and
M14
deliver
up
to
two
separate
64–port
fibre-channel
switches
in
a
single
chassis
(or
a
128–port
fibre-channel
switch,
M14
only).
Each
64–port
switch
uses
four
16–port
blade
assemblies.
The
blade
assemblies
for
the
M12
and
M14
are
the
same
form
factor,
but
have
observable
differences
in
the
ejectors,
the
ON/OFF
switches,
and
the
spacing
of
the
ports.
See
Figure
4
and
Figure
5
on
page
14
to
compare
the
different
16–port
cards.
The
differences
between
the
M12
and
M14
CP
blades
are
also
most
easily
seen
in
the
ejectors
and
the
ON/OFF
switches.
