PowerApp 200 User`s Guide Intorduction

The Dell™ PowerApp™ 200 appliance is an ultra-slim, full-featured, rack-mounted,
turn-key device with an embedded operating system. Combined with innovative setup
and administrative tools and utilities, the PowerApp 200 provides specific and reliable
functionality in a rack-dense form factor.
PowerApp systems offer the following major features:
One Intel® Pentium® III microprocessor.
The Pentium III microprocessor includes MMX™ technology designed to handle
complex multimedia and communications software. This microprocessor
incorporates new instructions and data types as well as a technique called single
instruction, multiple data (SIMD) that allows the microprocessor to process
multiple data elements in parallel, thereby improving overall system performance.
A secondary level 2 (L2) cache of static random-access memory (SRAM) is
included within the single-edge contact (SEC) cartridge that contains the
microprocessor. Math coprocessor functions are provided by the microprocessor.
A separate and external math coprocessor chip is not used or required.
The size of the L2 cache is dependent on the processor installed in the system.

Front side bus (FSB) with an external bus speed of 133 megahertz (MHz).
A minimum of 512 megabytes (MB) of system memory, with a maximum of 2
gigabytes (GB) installed in combinations of 128-MB, 512-MB, 1-GB, or 2-GB registered synchronous dynamic RAM (SDRAM) dual in-line memory modules
(DIMMs) in the four DIMM sockets on the system board.
A basic input/output system (BIOS) that resides in flash memory on the Peripheral Component Interconnect (PCI) bus.
Support for up to four 1-inch, hot-pluggable small computer system interface
(SCSI) hard-disk drives. One additional 1-inch hard-disk drive can be installed in
the optional removable media bay.
Introduction

A power-supply distribution board to accommodate up to two independent power
supplies. One power supply is standard; a second can be added to make the system redundant.
A single 1.44-MB, 3.5-inch diskette drive.
A 24X integrated drive electronics (IDE) CD-ROM drive.
The system board includes the following integrated features:
Three PCI slots located on the riser card.
An Intel PRO/100+ network interface controller (NIC), which provides an Ethernet
interface.
An Adaptec AIC-7899 Ultra3 (Ultra160) SCSI host adapter that supports up to five
SCSI hard-disk drives (four 1-inch hard-disk drives via a SCSI backplane board and
one 1-inch hard-disk drive via an optional SCSI hard-disk drive media bay). The
SCSI backplane automatically configures SCSI ID numbers and SCSI termination
on individual hard-disk drives, greatly simplifying drive installation.
A video graphics array (VGA)-compatible video subsystem with an ATI RAGE IIC
video controller. This video subsystem contains 4 MB of SDRAM video memory
(nonupgradable). Maximum resolution is 1600 x 1200 x 256 colors
(noninterlaced).
A National Semiconductor PC97317 super input/output (I/O) controller that controls the bidirectional parallel port, two serial ports, keyboard, mouse, and the
diskette drive.
Server management circuitry that monitors operation of the system fans as well
as critical system voltages and temperatures.
System board support for the Dell OpenManage™ Remote Assistant when the
optional Dell OpenManage Remote Assistant Card 2 (DRAC 2) is installed, which
provides additional local and remote server management.
A Personal System/2 (PS/2)-style keyboard port, dual Universal Serial Bus (USB)
ports, and a PS/2-compatible mouse port.
Standard PowerApp systems include a 3.5-inch diskette drive and an IDE CD-ROM
drive installed in the externally accessible bays and a SCSI hard-disk drive installed in
slot 0.
The following software is included with your PowerApp system:
Diagnostics for evaluating your system’s components and devices. For information on using the system diagnostics, see “Running the Dell Diagnostics” in your
Troubleshooting Guide.
Kickstart configuration utility and reinstallation media for the appliance.
Your Dell PowerApp system was preinstalled with an operating system. See the operating system documentation for additional information.

The following controls and indicators are behind the bezel on the computer's front
panel (see Figure 1-1).

and power
indicator
The power button/indicator on the front panel controls the AC power input to the
system's power supply.
The green indicator in the center of the power button lights up when the power
supply is turned on and the system is receiving DC power. When the system is in
sleep mode the power indicator is amber.
The following indicators are on the system's front panel.
The green system status indicator blinks amber when a system failure is
detected.
The green hard-disk drive activity indicator lights when the hard-disk drives are in
use.
You can connect various external devices, such as a mouse and printer, to the I/O
ports and connectors on the computer’s back panel (see Figure 1-2).

The system BIOS detects the presence of external devices when you boot or reboot
your system. When you connect external devices to your computer, follow these
guidelines:
Check the documentation that accompanied the device for specific installation
and configuration instructions.
For example, most devices must be connected to a particular I/O port or connector to operate properly. Also, external devices such as a mouse or printer usually
require that you load software files called device drivers into memory before they
will work. These software drivers help the computer recognize an external device
and direct its operation. Device drivers of this type are normally included with
your operating system software.
Always attach external devices while your computer is turned off. Then turn on
any external devices before turning on the computer unless the documentation
for the device specifies otherwise. (If the computer does not seem to recognize
the device, try turning on the computer before turning on the device.)
For information about enabling, disabling, or configuring I/O ports and connectors, see
the software documentation that came with your system. For detailed descriptions
and illustrations of each port and connector on the I/O panel, see Appendix B, “I/O
Ports and Connectors.”
A keylock on the top of the system prevents unauthorized access to the system.
If at any time you do not understand a procedure described in this guide, or if your
system does not perform as expected, Dell provides a number of tools to help you.
