Power problems
v Follow the suggested actions in the order in which they are listed in the Action column until the problem
is solved.
v See Chapter 3, “Parts listing, System x3200 Types 4362 and 4363,” on page 67 to determine which
components are customer replaceable units (CRU) and which components are field replaceable units
(FRU).
v If an action step is preceded by “(Trained service technician only),” that step must be performed only by a
trained service technician.
Symptom Action
The power-control button does
not work (the server does not
start).
Note: The power-control button
will not function until 20
seconds after the server has
been connected to ac power.
1. Make sure that the front-panel assembly power-control button is working
correctly:
a. Disconnect the server power cords.
b. Reconnect the power cords.
c. Press the power-control button.
d. If the server does not start, bypass the front-panel assembly power-control
button by using the force power-on jumper (see “System-board jumpers” on
page 13). If the server starts, reseat the front-panel assembly cable and
repeat steps 1a through 1c. If the problem remains, replace the front-panel
assembly.
2.
Make sure that:
v The power cords are correctly connected to the server and to a working
electrical outlet.
v The server contains the correct type of DIMMs.
v The DIMMs are correctly seated.
v The LEDs on the power supply do not indicate a problem.
v The microprocessor is correctly installed.
3.
Reseat the following components:
a. DIMMs
b. Power supply cables to all internal components
c. Power supplies (hot-swap models)
4.
Replace the following components one at a time, in the order shown, restarting
the server each time:
a. DIMMs
b. Power supplies (hot-swap models)
c. (Trained service technician only) Power supply (non-hot swap models)
5.
If you just installed an optional device, remove it, and restart the server. If the
server now starts, you might have installed more devices than the power supply
supports.
6. See “Solving undetermined problems” on page 64.
The server does not turn off.
1. Determine whether you are using an Advanced Configuration and Power
Interface (ACPI) or a non-ACPI operating system. If you are using a non-ACPI
operating system, complete the following steps:
a. Press Ctrl+Alt+Delete.
b. Turn off the server by holding the power-control button for 5 seconds.
c. Restart the server.
d. If the server fails POST and the power-control button does not work,
disconnect the ac power cord for 20 seconds; then, reconnect the ac power
cord and restart the server.
2.
(Trained service technician only) If the problem remains or if you are using an
ACPI-aware operating system, suspect the system board.
