Note: See "System replaceable units" on page 144 to determine which components should be replaced by a field service technician. Symptom FRU/action An IBM option that used to work 1. Verify that all of the option hardware and cable connections are secure. does not work now. 2. If the option comes with its own test instructions, use those instructions to test the option. 3. If the failing option is a SCSI option, verify that: v The cables for all external SCSI options are connected correctly. v The last option in each SCSI chain, or the end of the SCSI cable, is terminated correctly. v Any external SCSI option is turned on. You must turn on an external SCSI option before turning on the server. 4. Failing option. Power error symptoms Note: See "System replaceable units" on page 144 to determine which components should be replaced by a field service technician. Symptom FRU/action The power switch does not work 1. Reseat the connector. and the reset button, if supported, does work. 2. Power switch card. 3. System board. The server does not turn on. 1. Verify that: v The power cables are properly connected to the server. v The power supply LEDs indicate correct operation (see "Power-supply LED errors" on page 116). v The electrical outlet functions properly. v The type of memory installed is supported by the server, and that functional DIMMs are installed in slots 1 and 2. v If you just installed an option, remove it, and restart the server. If the server now turns on, you might have installed more options than the power supply supports. 2. If LEDs for microprocessors or VRMs are on, verify that: a. A VRM is installed if a second microprocessor is present. b. All microprocessors have the same speed. 3. Override front panel power button: a. Disconnect server power cords. b. Move the force power-on password switch (SW1) from its upward position to its lower position. c. Reconnect power cords. If server turns on: a. Service processor (baseboard management controller) error. b. Operator information card. If server does not turn on: v System board Chapter 6. Symptom-to-FRU index 129

to
determine
which
components
should
be
replaced
by
a
field
service
technician.
Symptom
FRU/action
An
IBM
option
that
used
to
work
does
not
work
now.
1.
Verify
that
all
of
the
option
hardware
and
cable
connections
are
secure.
2.
If
the
option
comes
with
its
own
test
instructions,
use
those
instructions
to
test
the
option.
3.
If
the
failing
option
is
a
SCSI
option,
verify
that:
v
The
cables
for
all
external
SCSI
options
are
connected
correctly.
v
The
last
option
in
each
SCSI
chain,
or
the
end
of
the
SCSI
cable,
is
terminated
correctly.
v
Any
external
SCSI
option
is
turned
on.
You
must
turn
on
an
external
SCSI
option
before
turning
on
the
server.
