3: Removing and Installing Baseboard Components
!
68
Warning:
If the system has been running, any installed PCI add-in board on the
baseboard will be hot. To avoid the possibility of a burn, be careful when removing or
installing baseboard components, especially those that are located near processors.
Caution: Slot covers must be installed on all vacant expansion slots. This maintains the
electromagnetic emissions characteristics of the system and ensures proper cooling of
system components.
Note: At this time, the Linux operating system does not support use of the PCI hot-plug
(PHP) feature. If you are running Linux, your system must be turned off before installing
or removing PCI boards. Windows 2000 requires drivers that are PHP-compatible in
order to use the PHP feature.
