NOTE: You must install Windows NT 4. 0 Service Pack 4 or 5 before you install the NIC drivers. Otherwise, the integrated NIC will not
function properly.
See the Dell Microsoft Windows NT Workstation 4.0 Setup Guide for general installation information for Windows NT 4.0 and for information
about other drivers or supplements that may be required. For installation instructions for the various drivers, see the documents recommended in
the following list:
Windows NT 4.0 SCSI controller drivers — See the documentation that came with your Dell Precision ResourceCD.
l
Windows NT 4.0 bus-mastering EIDE driver — See the documentation that came with your Dell Precision ResourceCD.
l
Windows NT 4.0 video drivers — See the documentation for your video card.
l
Windows NT 4.0 NIC driver — See the documentation that came with your Dell Precision ResourceCD.

Front Panel
The computer system's front panel contains the following indicators and controls (see
The power button controls the system's DC input power. When the system is turned off, pressing the power button turns the system on. When
l
the system is on, the power button operates as follows:
In Windows NT, if the Dell AutoShutdown service is operational, the system performs an orderly operating system shutdown
¡
before turning off.
If the Dell AutoShutdown service is not operational, the system turns off without writing unsaved data to the disk. This could result
in loss of data.
In Windows 2000, the system performs an orderly operating system shutdown before turning off. However, the power button can
¡
be configured to put the computer in a low-power sleep state.
When the system is on, the power indicator light-emitting diode (LED) displays a solid green. When the system is in a
software-induced sleep state, the power indicator displays a blinking green. When you press the power button to turn off the
system, the power indicator turns off; however, the power supply maintains a low-voltage (standby) current. To completely
remove all power from the system, unplug the DC power cable from its electrical outlet and disconnect the network and
telephone cables.
NOTE: A Display Power Management Signaling (DPMS) monitor does not begin warming up until the computer to which it is
attached is turned on. Thus, some DPMS monitors may not display a video image until several seconds after you turn on
the computer.
The power indicator LED is green during normal system operation and blinks green when the system is in sleep mode.
l
The hard-disk drive access indicator lights up when a hard-disk drive is in use.
l
NOTE: The power and hard-disk drive access LEDs are also used to display
The diskette-drive access indicator lights up when the diskette drive is in use. (The drive access indicator for the tape drive is located on the
l
front of the drive.)
The reset button reboots (restarts) the system without your having to turn the power off and then on again. Rebooting the system in this
l
manner reduces stress on system components.
