Never remove a PCI Hot Plug board from a hot-plug slot without first powering
down the slot through software. Doing so interferes with the operation of the board's
Hot Plug driver. As a consequence, the board will not resume I/O operation when
replaced. Also, you will not be able to power up the slot again through software. If
the board in a Hot Plug slot does not have Hot Plug drivers, you cannot power it
down through software. Do not remove the board while the server is running.
Power to the slot is on, and the slot is operating normally. Do not remove
the board from the slot.
Power to the slot is on, but the slot needs attention. Do not remove the
board from the slot.
Power to the slot is off, and the slot needs attention. You can remove the
board from this slot.
Power to the slot is off. You can remove the board from this slot.
If you have a non-hot-plug board in one of the hot-plug slots, the board will show up
on the interface. But the interface will not allow you to power down the board's slot If
you do not replace the Hot Plug bracket, you cannot power up the slot again.
