NOTES: In order to meet PC99 requirements, your Dell system uses only PCI expansion slots. Industry-Standard Architecture (ISA)
expansion cards are not supported.
Before disconnecting a peripheral from the system or removing a component from the system board, verify that the standby power light-
emitting diode (LED) on the system board has turned off. For the location of this LED, see
Figure 3 in "Inside Your Computer."

shock, be sure to unplug your computer from its electrical outlet before installing any expansion cards.
