Ensure that the MPB16-4 boards are release 5 or later.
Ensure that the PCI backplane does not have Intel PCI bridge chips.
Shut down the server and open the lid. Power up the server and
check if the PCI LED on the MPB16-4 board is still on after startup.
If the LED still stays on, shut down the server and replace the board.

If the PCI LED comes on at system startup and then turns off, but
the other four green LEDs are still off after the system booted to the
operating system, check the HAL and ensure that all its components
are working properly. If the HAL components are working properly,
one or more MPC8 cards can be defective. Replace the defective
MPC8 cards.

If your system has two MPB16-4 boards and both have the same
symptoms, ensure that the correct driver is installed.

If only one MPB16-4 board seems to be defective, swap the boards.
If the presumed defective board works after the swapping, then the
PCI backplane is defective and you must replace it. If the presumed
defective board does not work, then you must replace it.
