Table 3
lists
the
meanings
assigned
to
the
light
color/activity
of
each
Base/Fabric
LED.
Note:
The
Fabric
channel
LEDs
can
be
either
green
or
amber
when
linked
or
indicating
activity
at
10
Gbps.
This
is
because
in
one
configuration
10
Gbps
is
the
low
range
output
from
the
controller
while
in
another
configuration
it
is
the
high
range
output.
The
LED
indicates
the
low/high
range
output,
not
the
actual
link
speed.
Reset and hot swap switches
The
CPM
front
panel
Reset
button
(switch)
is
recessed
and
can
normally
be
pressed
only
with
a
thin,
pointed
object
such
as
a
pencil
or
stylus.
A
callout
in
Figure 2
points
out
the
Reset
button
on
the
CPM
front
panel.
The
Reset
button
performs
a
platform
reset
of
the
CPM.
A
platform
reset
returns
all
registers
and
devices
(except
the
IPMC)
to
their
default
state.
The
ejector
latches
and
thumbscrews
are
considered
hot
swap
hardware
components.
Both
thumbscrews
must
be
unscrewed
in
order
to
remove
the
CPM
from
its
slot.
The
bottom
lock
and
ejector
switch
must
be
disengaged
in
order
to
signal
to
the
IPMC
that
a
CPM
hot
swap
is
desired.
The
IPMC
then
controls
the
hot
swap
LED
and
monitors
the
process.
Headers and jumpers
Refer
to
Appendix
C,
Onboard
switches,
headers,
and
connectors,
on
page 114
for
tables
detailing
the
header
and
jumper
callouts.
