Intermittent
problems
Action
A
problem
occurs
only
occasionally
and
is
difficult
to
diagnose.
1.
Make
sure
that:
v
All
cables
and
cords
are
connected
securely
to
the
rear
of
the
server
and
attached
devices.
v
When
the
server
is
turned
on,
air
is
flowing
from
the
fan
grille.
If
there
is
no
airflow,
the
fan
is
not
working.
This
can
cause
the
server
to
overheat
and
shut
down.
2.
Check
the
system-error
log
or
BMC
log.
Standard
or
USB
keyboard,
mouse,
or
pointing-device
problems
Action
All
or
some
keys
on
the
keyboard
do
not
work.
1.
(USB
keyboard)
If
you
have
installed
a
USB
keyboard,
run
the
Configuration/Setup
Utility
program
and
enable
keyboardless
operation
to
prevent
the
POST
error
message
301
from
being
displayed
during
startup.
2.
(Standard
keyboard)
If
the
server
is
attached
to
a
KVM
switch,
bypass
the
KVM
switch
to
eliminate
it
as
a
possible
cause
of
the
problem:
connect
the
keyboard
cable
directly
to
the
correct
connector
on
the
rear
of
the
server.
3.
Make
sure
that:
v
The
keyboard
cable
or
USB
cable
is
securely
connected
to
the
server
and
the
keyboard
and
mouse
cables
are
not
reversed.
v
The
server
and
the
monitor
are
turned
on.
4.
Reseat
the
following
components:
a.
Keyboard
b.
I/O
board
5.
Replace
the
components
listed
in
step
one
at
a
time,
