Solving
problems
This
section
provides
basic
troubleshooting
information
to
help
you
solve
some
problems
that
might
occur
while
you
are
setting
up
the
GbE
switch
module.
The
Nortel
10
Gb
Uplink
Ethernet
Switch
Modules
for
IBM
Bladecenter
Application
Guide
provides
more
details
about
troubleshooting
the
GbE
switch
module.
If
you
cannot
locate
and
correct
the
problem
using
the
information
in
this
section,
see
Running
POST
To
ensure
that
it
is
fully
operational,
the
GbE
switch
module
processes
a
series
of
tests
during
power-up
or
a
restart
(power-on
self-test,
or
POST).
These
tests
take
approximately
1
minute
to
complete.
The
management
module
reads
the
test
results
and
displays
them
for
you.
During
normal
operation,
these
tests
are
completed
without
error,
and
the
green
OK
LED
is
lit.
However,
if
the
GbE
switch
module
fails
POST,
the
amber
error
(fault)
LED
and
the
system-error
LED
on
the
BladeCenter
unit
is
lit.
An
event
is
stored
in
the
event
log
in
the
System
Status
panel
of
the
management
module.
The
specific
failure
is
displayed
on
the
System
Status
I/O
Module
panel
of
the
management
module.
Note:
For
the
location
and

LEDs,
see
POST
errors
There
are
two
types
of
errors:
noncritical
and
critical.
Noncritical
errors
apply
to
one
port,
and
the
GbE
switch
module
is
operational.
You
can
continue
to
operate
the
GbE
switch
module;
however,
if
necessary,
you
must
replace
it
as
soon
as
possible.
When
critical
errors
occur,
the
GbE
switch
module
does
not
operate.
If
a
critical
error
occurs,
the
switch
will
try
complete
the
startup
sequence
and
initialization
process.
To
view
POST
results,
complete
the
following
steps:
1.
Log
on
to
the
management
module
as
described
in
the
User’s
Guide
or
the
Command
Line
Interface
Reference
Guide
for
your
management
module.
If
necessary,
obtain
the
IP
address
of
the
management
module
from
your
system
administrator.
The
login
window
opens.
2.
Turn
off
the
power
to
the
GbE
switch
module;
then,
turn
it
on
again.
3.
After
POST
is
completed,
the
management
module
displays
the
results.
Refresh
the
window
to
view
the
POST
results.
If
a
critical
error
occurs,
replace
the
GbE
switch
module.
If
a
non-critical
error
occurs,
see
the
GbE
switch
module
error
log
for
additional
details.
