Operating system support for hot-plug
add-in boards
Some operating systems support hot-plugging PCI add-in boards and
some do not. Operating system support is provided by a driver that
you must install when setting up your server. Hot-plug drivers are
available on the Drivers directory of the System CD. The driver files on
the CD include information on installing and using the hot-plug
software.
Without a driver, the operating system does not support hot-plug
installation and removal of PCI add-in boards. In that case, you must
treat all eight PCI slots as non-hot-plug slots and follow the instructions
on page 74 for installing and removing all PCI add-in boards.
Checking the status indicators for a hot-plug
add-in board
A bank of LED indicators on the back panel of the electronics bay
indicates the status of the hot-plug PCI add-in boards.
The table below lists the LED states and the hot-plug PCI status
indicated by each state.
