support.dell.com Introduction 1-3
Dell supports the following network operating systems for use on PowerEdge 1400
systems:
Windows NT Server 4.0 and Windows 2000 Server
NetWare 5.1 (and later versions)
Red Hat Linux 6.2 release SBE2 (and later versions)
Microsoft BackOffice Small Business Server (SBS) 4.5 (and later versions)
The computer's front panel contains the following indicators and controls
(see Figure 1-1):
The power button provides control of the system's alternating current (AC) input
power. The push-button switch operates as follows:
— When the computer is turned off, pressing the button turns the computer on.
— When the computer is turned on, pressing the button turns the computer off.
However, a low-voltage (standby) current is maintained by the power supply.
To completely remove all power from the system, unplug the AC power
cable from its source.
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 light is green during normal system operation and amber
when the computer is in sleep mode.
The hard-disk drive access indicator lights up when a hard-disk drive is in use.
(Drive access indicators for diskette drives and tape drives are located on the
front of the drives.)
The reset button reboots (restarts) the system without your having to turn the
power off and then on again. Rebooting the system in this manner reduces
stress on system components.
