Chapter 6
CAUTION 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.
NOTE
If you want, you can reverse steps 2 and 3: power off the slot
through software before opening the Hot Plug access panel.
