POST Errors
There
are
two
types
of
errors:
noncritical
and
critical.
A
noncritical
error
applies
to
one
port,
and
the
switch
is
operational.
You
can
continue
to
operate
the
switch;
however,
you
must
replace
it
as
soon
as
possible.
When
critical
errors
occur,
the
switch
does
not
operate.
To
view
POST
results,
complete
the
following
steps:
1.
Log
on
to
the
CMM
Command
‐
Line
Interface
(CLI)
as
described
in
the
CMM
documentation.
If
necessary,
obtain
the
Internet
Protocol
(IP)
address
of
the
CMM
from
your
system
administrator.
The
login
window
opens.
2.
Turn
off
the
power
to
the
switch;
then,
turn
it
on
again.
3.
After
POST
is
completed,
the
CMM
displays
the
results.
Refresh
the
window
to
view
the
POST
results.
If
a
critical
error
occurs,
replace
the
switch.
If
a
noncritical
error
occurs,
see
the
switch
error
log
for
additional
details.
The
following
table
describes
the
basic
critical
and
noncritical
failures.
This
abbreviated
list
is
representative;
it
is
not
an
exhaustive
list.
An
error
code
is
associated
with
each
failure.
Error
codes
are
displayed
on
the
CMM
Switch
Information
window.
Be
sure
to
note
the
applicable
error
code
and
corresponding
failure.
You
might
have
to
provide
this
information
when
you
call
for
service.
