• Follow the suggested actions in the order in which they are listed in the Action column until the problem is
solved.
• See Chapter 5 "Parts listing, IBM System x3530 M4 Type 7160" on page 147 to check if a component is a
consumable, structural, or FRU part.
• If an action step is preceded by "(Trained technician only)," that step must be performed only by a trained
technician.

Solving power problems
Use this information to solve power problems.
Power problems can be difficult to solve. For example, a short circuit can exist anywhere on any of the
power distribution buses. Usually, a short circuit will cause the power subsystem to shut down because of
an overcurrent condition. To diagnose a power problem, use the following general procedure:
Step 1.
Turn off the server and disconnect all ac power cords.
Step 2.
Check for loose cables in the power subsystem. Also check for short circuits, for example, if a
loose screw is causing a short circuit on a circuit board.
Step 3.
If the system-error LED on the system board is lit, complete the following steps:
a.
Check the IMM2 event log. To access the web interface, see "Logging on to the Web
interface" on page 94.
b.
If a log indicates that there is a power rail failure, find the location of the failed power rail
on the system board.
c.
Disconnect the cables and power cords to all internal and external devices (see "Internal cable
routing" on page 161). Leave the power-supply cords connected.
d.
Remove each component that is associated with the failed power component, one at a time,
restarting the server each time, until the cause of the failure is identified.
e.
Replace the identified component.
Step 4.
Reconnect all power cords and turn on the server. If the server starts successfully, replace the
adapters and devices one at a time until the problem is isolated.
If the server does not start from the minimum configuration, see "Power-supply LEDs" on page 119 to
replace the components in the minimum configuration one at a time until the problem is isolated.
Solving Ethernet controller problems
Use this information to solve the Ethernet controller problems.
Action
• The operating system supports USB devices.
2. Make sure that the USB configuration options are set correctly in the Setup
utility (see "Using the Setup utility" on page 83 for more information).
3. If you are using a USB hub, disconnect the USB device from the hub and
connect it directly to the server.
