Attention:
Disassembling
any
part
of
the
blower
assembly
voids
the
part
warranty
and
regulatory
certifications.
CAUTION:
No
user-serviceable
parts
are
inside
the
blower
assembly.
Perform
the
following
steps
to
determine
the
status
of
a
blower
assembly:
1.
Check
the
LEDs
on
the
blower
assembly.
2.
Check
the
blower
assembly
status
by
using
the
fanShow
command.
The
status
for
each
blower
assembly
displays
OK,
absent,
or
faulty.
For
additional
information
about
the
fanShow
command,
see
the
Brocade
Fabric
OS
Reference
.
WWN
card
and
bezel
The
WWN
card
and
bezel
are
located
at
the
top
of
the
chassis
on
the
blower
assembly
side.
The
WWN
card
has
LEDs
that
you
use
to
monitor
the
switch.
The
WWN
card
also
stores
the
following
information:
v
The
chassis
serial
number
(used
when
installing
software
licenses)
v
The
two
native
IP
addresses
that
are
assigned
to
the
CP
card
slots
v
The
logical
switch
names,
IP
addresses,
and
WWNs
for
the
two
logical
switches
The
bezel
protects
the
card
and
identifies
each
of
the
LEDs
on
the
WWN
card.
Together,
the
WWN
card
and
bezel
assembly
provides
a
consolidated
view
of
the
LEDs
for
the
two
CP
cards,
eight
16–port
cards,
and
four
power
supplies.
If
a
slot
contains
a
filler
panel,
the
corresponding
LEDs
on
the
WWN
card
are
not
illuminated.
Note:
There
are
two
types
of
WWN
cards.
One
type
is
attached
to
the
chassis
by
screws
and
the
other
type
is
held
on
by
the
pressure
of
the
bezel
against
a
pad
on
the
card
face.
Attention:
Although
the
information
that
is
stored
in
the
WWN
card
is
also
stored
in
the
flash
memory
of
the
CP
cards,
do
not
restart
the
switch
while
the
WWN
card
is
uninstalled.
Restarting
the
switch
can
cause
the
switch
to
start
incorrectly.
Attention:
Wear
an
ESD
grounding
strap
when
you
work
with
the
WWN
card
to
prevent
damage
to
the
electrical
components.
Cable
management
items
Two
items
are
provided
to
assist
with
cable
management:
v
Cable
management
tray
The
cable
management
tray
is
attached
to
the
bottom
of
the
chassis.
You
can
use
it
to
route
the
power
cables
and
other
cables
down
below
the
chassis
or
out
the
sides
of
the
chassis.
v
Cable
guides
A
set
of
16
cable
guides
is
provided
with
the
cabinet.
You
can
use
the
guides
to
organize
the
port
cables
into
logical
groups,
such
as
port
quads
(sets
of
four
neighboring
ports).
The
cable
guides
are
free-floating
and
do
not
attach
to
the
chassis.
The
cable
guides
keep
the
cables
evenly
spaced
and
hold
them
away
from
the
16–port
cards.
This
makes
card
replacement
easier
and
prevents
the
cables
from
bending
to
less
than
the
minimum
bend
radius.
