pnt0-21 add_intr_handler failed! Out of range interrupt number.
Explanation: The interrupt request (IRQ) that was specified, or the IRQ that was found,
conflicts with other devices in the server. Action:
v Modify your hardware settings.
v Run the NETCONFIG program to search for another Ethernet controller.
pnt0-22 add_intr_handler failed! Out of range 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.
pnt0-23 add_intr_handler failed! Vector already occupied.
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.
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:
v Modify your hardware settings.
v 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

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
3. Remove adapters and disconnect the cables and power connectors to all
4. Reconnect the AC cord and power on the system. If the system powers up

internal and external devices until system is at minimum configuration
required for power on (see "Minimum operating requirements" on page 144).
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.
