his manual contains field-servicing information for the Dell
®
OptiPlex
®
GXa and Optiplex NX family of computers. The Dell OptiPlex GXa and

technology.
The OptiPlex GXa systems use either a standard system board with integrated
NIC controller or an enhanced manageability (EM) system board with optional
NIC controller and support for an optional Network Interface Card with Wake-
up On LAN capability. All OptiPlex NX systems use the EM system board.
Enhanced manageability systems are identified by the phrase “Enhanced Man-
ageability,” which is printed on the computer’s FCC label and also displayed in
the boot banner when the computer is powered up.
The OptiPlex GXa systems are available in three different chassis configura-
tions: low-profile desktop, midsize desktop, and mini tower (see Figure 1-1).
The OptiPlex NX computer is available only in the Net PC chassis (see
Figure 1-1).
Chapters 1 through 3 and Appendix A contain information that applies to all
models of the OptiPlex GXa and OptiPlex NX families; Chapters 4, 5, 6, and 7
are chassis-specific.
