Network
connection
problems
To
check
for
network
connection
problems,
complete
the
following
steps
until
the
problem
is
solved:
1.
Make
sure
that:
v
The
network
cables
are
securely
connected
to
the
I/O
module.
v
Power
configuration
of
the
BladeCenter
unit
supports
the
I/O
module
configuration.
v
Installation
of
the
I/O-module
type
is
supported
by
the
BladeCenter
unit
and
blade
server
hardware.
v
The
I/O
modules
for
the
network
interface
that
is
being
used
are
installed
in
the
correct
BladeCenter
bays,
and
are
configured
and
operating
correctly.
v
The
settings
in
the
I/O
module
are
correct
for
the
blade
server
(settings
in
the
I/O
module
are
specific
to
each
blade
server).
2.
Check
for
correct
I/O-module
operation;
troubleshoot
and
replace
the
I/O
module
as
indicated
in
the
documentation
for
the
I/O
module.
3.
Check
for
correct
management-module
operation
(see
the
documentation
for
your
BladeCenter
unit).
Note:
Some
BladeCenter
unit
types
have
several
management-module
components
that
might
need
to
be
tested
or
replaced
(see
the
Installation
Guide
for
your
management
module
for
more
information).
4.
Replace
the
management
module
(see
the
documentation
for
your
BladeCenter
unit).
If
these
steps
do
not
resolve
the
problem,
it
is
likely
a
problem
with
the
blade
server.
See
“Network
connection
problems”
on
page
86.
Power
problems
To
check
for
power
problems,
make
sure
that:
v
The
LEDs
on
all
the
BladeCenter
power
modules
are
lit.
v
Power
is
being
supplied
to
the
BladeCenter
unit.
v
Installation
of
the
blade
server
type
is
supported
by
the
BladeCenter
unit.
v
The
BladeCenter
unit
has
the
correct
power
configuration
to
operate
the
blade
bay
where
your
blade
server
is
installed
(see
the
documentation
for
your
BladeCenter
unit).
v
The
BladeCenter
unit
power
management
configuration
and
status
support
blade
server
operation
(see
the
Management
Module
User’s
Guide
or
the
Management
Module
Command-Line
Interface
Reference
Guide
for
information).
v
Local
power
control
for
the
blade
server
is
correctly
set
(see
the
Management
Module
User’s
Guide
or
the
Management
Module
Command-Line
Interface
Reference
Guide
for
information).
v
The
BladeCenter
unit
blowers
are
correctly
installed
and
operational.
If
these
operations
do
not
solve
the
problem,
it
is
likely
a
problem
with
the
blade
server.
