Power problems can be difficult to troubleshoot. For instance, a short circuit can exist
anywhere on any of the power distribution busses. Usually a short circuit will cause
the power subsystem to shut down because of an overcurrent condition.
A general procedure for troubleshooting power problems is as follows:
1. Power off the system and disconnect the AC cord(s).
2. Check for loose cables in the power subsystem. Also check for short circuits, for
instance if there is a loose screw causing a short circuit on a circuit board.
3. Remove adapters and disconnect the cables and power connectors to all internal
and external devices until system is at minimum configuration required for
power on (see "Minimum operating requirements" on page 130).
4. Reconnect the AC cord and power on the system. If the system powers up
successfully, replace adapters and devices one at a time until the problem is
isolated. If system does not power up from minimal configuration, replace FRUs
of minimal configuration one at a time until the problem is isolated.
To use this method it is important to know the minimum configuration required for a
system to power up (see page 130). For specific problems, see“Power error messages”
on page 127.
Replacing the battery
IBM has designed this product with your safety in mind. The lithium battery must be
handled correctly to avoid possible danger. If you replace the battery, you must
adhere to the following instructions.
CAUTION: When replacing the battery, use only IBM Part Number 10L6432 or an
equivalent type battery recommended by the manufacturer. If your
system has a module containing a lithium battery, replace it only with
the same module type made by the same manufacturer. The battery
pnt0-24 add_intr_handler failed! Vector already shared at different IPL.
Explanation:
The interrupt request (IRQ) that was specified, or the IRQ that was found, conflicts
with other devices in the server.
Action:
• Modify your hardware settings.
• Run the NETCONFIG program to search for another Ethernet controller.
pnt0-26 The DMA number is not necessary for PCI device.
Explanation: The IBM Netfinity 10/100 Fault Tolerant Adapter does not require a DMA setting.
Action: Edit the SPACE.C file to delete the DMA parameter.
pnt0-29
The IRQ number is already in use.
Explanation: The specified I/O address is already in use.
Action: Run the NETCONFIG program to modify your hardware settings.
pnt0-31 I/O address is not necessary for the PCI device.
Explanation: The I/O address specified is not required.
Action: Remove the assigned I/O address specified for the Ethernet controller
