NOTES: To meet PC99 Workstation 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 8

in "Inside Your Computer."

shock, be sure to unplug your computer from its electrical outlet before installing any expansion cards. Verify that the
standby power light-emitting diode (LED) on the system board is off.
