Overview

The Dell PowerEdge 2400 workgroup server is a high performance system that offers strong availability, serviceability, and manageability features. The PowerEdge 2400 server utilizes Intel® Pentium® III microprocessors and next-generation chipset and memory technology to provide high performance in both file/print and server application environments.

This section describes the major hardware and software features of the computer, provides information about the indicators and controls on the computer's front panel, and discusses connecting external devices to the computer.


System Features

The PowerEdge 2400 systems offer the following major features:

  • One or two Pentium III microprocessors with an external bus speed of 100 or 133 megahertz (MHz) and an internal operating speed of at least 450 MHz. The System Setup screens list your system's internal processor speed.  For more information, see "Using the System Setup Program."

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 256 kilobytes (KB) or 512 KB 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.

  • Support for symmetric multiprocessing is available by installing a second Pentium III microprocessor. Symmetric multiprocessing greatly improves overall system performance by dividing microprocessor operations between the two independent microprocessors. To take advantage of this feature, you must use an operating system that supports multiprocessing, such as Microsoft® Windows NT® Server 4.0 or Novell® NetWare® 4.2 (and later versions).
note.gif (515 bytes) NOTE: If you decide to upgrade your system by installing a second microprocessor, you must order a microprocessor upgrade kit from Dell. Not all versions of the Pentium III microprocessor work properly as a second microprocessor. The upgrade kit from Dell contains the correct version of the microprocessor for use as a second microprocessor as well as instructions for performing the upgrade. The second microprocessor must have the same internal operating frequency as the first.
  • A minimum of 64 megabytes (MB) of system memory, upgradable to a maximum of 2 gigabytes (GB) by installing combinations of 64-, 128-, 256-, or 512 MB registered synchronous dynamic RAM (SDRAM) dual in-line memory modules (DIMMs) in the four DIMM sockets on the system board.

The registered, 72-bit-wide (168 pin) error checking and correction (ECC) SDRAM DIMMs installed in PowerEdge 2400 systems support ECC to check for and correct memory errors. ECC is performed by the memory controller in the ServerSet LE system chip set. DIMMs do not need to be inserted in pairs.

  • A basic input/output system (BIOS) that resides in flash memory on the ISA bus that can be upgraded if required.
  • An optional, redundant power supply distribution board to accommodate up to two independent power supplies.
  • A single, 1.44 MB 3.5-inch diskette drive.
  • A 14/32X small computer system interface (SCSI) CD-ROM drive.

The system board includes the following features:

  • Five PCI slots and one PCI/ISA-shared expansion-card connector, located on the system board. PCI slots 1 through 4 are unshared, 64-bit, 33 MHz PCI slots; PCI slot 5 is a 64-bit, 33 MHz slot that is shared with ISA slot 5. Slot six provides a 32-bit, 33 MHz PCI slot for use with the optional Dell Remote Assistant Card (DRAC) or other PCI accessories.
  • An integrated video graphics array (VGA)-compatible video subsystem with an ATI RAGE IIC video controller. This video subsystem contains 4 MB of synchronous dynamic RAM (SDRAM) video memory (nonupgradable). Maximum resolutions are 1024 x 768 x 256 colors (noninterlaced). In 800 x 600-pixel and 640 x 480-pixel resolutions, 16.7 million colors are available for true-color graphics.
  • An integrated National Semiconductor PC97317 super input/output (I/O) controller that controls the bidirectional parallel port, two serial ports, keyboard, mouse, and the diskette drive in the externally accessible front bay. The super I/O controller resides on the ISA bus.
  • The parallel port can be set to operate in the following modes via the Parallel Mode option in the System Setup program: output-only (AT-compatible), bidirectional (Personal System/2 [PS/2]-compatible, or Extended Capabilities Port (ECP).

  • An integrated Intel 82559 10/100 network interface controller (NIC), which provides an Ethernet interface.
  • An integrated Adaptec AIC-7890 Ultra2/low-voltage differential (LVD) SCSI host adapter that supports up to six 1-inch or four 1.6-inch internal SCSI hard-disk drives via a SCSI backplane board and special SCSI hard-disk drive carriers. The SCSI backplane automatically configures SCSI ID numbers and SCSI termination on individual hard-disk drives, greatly simplifying drive installation. 
  • You can add support for redundant arrays of independent disks (RAID) levels 0, 1, 5, and 10 by enabling the optional integrated PowerEdge Expandable RAID Controller (PERC) 2/Si. (This upgrade includes a DIMM, hardware key, and RAID software.)

  • An integrated Adaptec AIC-7880 Ultra/Wide SCSI secondary host adapter (implemented as Ultra/Narrow) provides connections for tape drives and CD-ROMs via a 50-pin connector.
  • SCSI backplane options include a 1 x 4 and 1 x 6 hot-pluggable backplane. The hot-pluggable backplanes support hot-pluggable SCSI hard-disk drive installation and removal. The integrated SCSI controller resides on the PCI local bus for optimum performance.
  • Integrated server management circuitry that monitors operation of the system fans as well as critical system voltages and temperatures. The integrated server management circuitry works in conjunction with the optional HP OpenView Network Node Manager Special Edition (NNM SE) and the Dell Hardware Instrumentation Package (HIP) software package.
  • A PS/2-style keyboard port, dual Universal Serial Bus (USB) ports, and a PS/2-compatible mouse port.

The PowerEdge 2400 system is orderable in a floor-standing or a rack configuration and can be changed from one configuration to the other via customer kits.

The following software is included in your Dell computer system:

  • Video drivers for displaying many popular application programs in high-resolution modes. For more information on these drivers, see "Using the Dell OpenManage Server Assistant CD."
  • SCSI device drivers that allow the operating system to communicate with devices attached to the integrated SCSI subsystem. For more information on these drivers, see "Installing and Configuring SCSI Drivers."
  • The System Setup program for quickly viewing and changing the system configuration information for your computer.
  • The Resource Configuration Utility, which allows you to configure installed ISA expansion cards through software rather than on the hardware.
  • Enhanced security features available through either the System Setup program or the Resource Configuration Utility, including a user password and a supervisor password.
  • Diagnostics for evaluating your computer's components and devices. For information on using the system diagnostics, see "Using the Dell OpenManage Server Assistant CD" or see "Running the Dell Diagnostics" in your Installation and Troubleshooting Guide.

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 "Using the System Setup Program" or "Using the Resource Configuration Utility." For detailed descriptions and illustrations of each port and connector on the I/O panel, see "I/O Ports and Connectors."


Preventing Unauthorized Access Inside the Computer

A keylock on the front bezel prevents unauthorized access to the inside of the computer. The computer covers cannot be removed with the bezel locked.

The PowerEdge 2400 systems also include a system intrusion switch that signals appropriate server management software if the computer bezel is opened.
