System Overview: Dell™ PowerEdge™ 2500 and 2500SC Systems Service Manual
The Dell PowerEdge 2500 and 2500SC systems are full-featured servers. The PowerEdge 2500 is available in either rack or tower versions, and the PowerEdge 2500SC is available in a tower version only. Your system provides a robust, reliable platform on which all users can deploy their mission-critical applications. The system has one or two Intel® Pentium® III microprocessors and next-generation chip set and memory technology to provide high performance hardware platforms for a variety of server application environments.
The PowerEdge 2500SC does not support the following options that are supported by the PowerEdge 2500:
- Optional peripheral bay hot plug backplane and 2x1-inch drive cage
- Split SCSI backplane daughter card
- Rack mountable chassis
The hard-disk drive that boots your operating system has a Utility partition
containing complete diagnostics for your system. Also, a separate Dell
OpenManage Server Assistant CD is provided that includes diagnostics
software that you can download to a set of diskettes.
This section describes the major hardware and software features
of the system. It also describes hardware
features that simplify servicing.
The system offers the following major features:
- One or two Pentium III microprocessors with an internal operating frequency of at least
933 MHz and an external bus speed of 133 MHz.
A secondary level 2 (L2) cache of 256 KB synchronous random-access memory (SRAM) is included within the microprocessor. Math coprocessor functions are provided by the microprocessor. A separate and external math coprocessor chip is not used or required.
- Front side bus with an external bus speed of 133 megahertz (MHz).
- The PowerEdge 2500 provides support for symmetric multiprocessing (SMP) by installing a second Pentium
III microprocessor. SMP 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 SMP, such as Microsoft®
Windows 2000 Server or Advanced Server or Novell® NetWare® 5.x (the
PowerEdge 2500SC does not support Novell NetWare 5.x).
 |
NOTE: If you decide to upgrade the
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. Both microprocessors must have the same part number and revision (or
stepping) code, internal operating frequency, and cache size. |
- Embedded dual channel Ultra3 SCSI controller.
- Support for an optional integrated dual-channel integrated RAID controller
that supports RAID levels 0, 1, 5, and 10. The Ultra3 SCSI host adapter can become RAID capable
with the addition of the integrated RAID controller.
- A minimum of 128 megabytes (MB) of system memory, upgradable to a maximum of
4 gigabytes (GB) by installing combinations of 64-, 128-, 256-, 512-MB or 1GB registered SDRAM
memory module pairs in the six memory module sockets on the system board.
- A flash basic input/output system (BIOS) that can be upgraded if required.
- The PowerEdge 2500 supports up to eight 1-inch, internal, hot-pluggable Ultra3 SCSI hard-disk drives
(six 1-inch drives via a 1x6 SCSI backplane board, and two 1-inch hard-disk
drives via an optional 80-pin 1x2 backplane board.
The PowerEdge
2500SC supports up to six 1-inch, internal, hot-pluggable Ultra3 SCSI
hard-disk drives via a 1x6 SCSI backplane board. The PowerEdge 2500SC does
not support the optional 1x2 backplane and drive cage for the peripheral
bay.
- Up to three optional hot-pluggable 300-W power supplies in a 2+1 redundant
configuration.
- Four redundant, hot-pluggable system cooling fans.
- A single, 1.44-MB 3.5-inch diskette drive.
- An IDE CD-ROM drive.
The system board includes the following features:
- Seven peripheral component interconnect (PCI) slots. Slot 1 and 2 are 64-bit, 66
MHz that support +3.3 V expansion cards; the next three slots (slots 3 through slot 5) are 64-bit, 33 MHz; and slots 6 and 7 are 32-bit, 33 MHz. Slots 3 through 7 accept +5 V or universal
expansion cards. Slot 7 adds an additional connector for use with
the Dell DRAC 2 card (the DRAC 2 card is not supported in the PowerEdge 2500SC
version).
- An integrated video graphics array (VGA)-compatible video subsystem with an ATI RAGE XL
video controller. This video subsystem contains 8 MB of SDRAM video memory
(nonupgradable). Maximum resolutions is 1024 x 768 x 256 colors (noninterlaced).
In 800 x 600 pixel-resolutions, 16.7 million colors are available for
true-color graphics
- An integrated National Semiconductor PC97317 super I/O controller that controls
a serial port, keyboard, mouse, and the diskette drive.
- An integrated Intel 82559 PRO/100+ NIC, which provide an Ethernet
interface.
- An integrated Adaptec AIC-7899 Ultra3 SCSI host adapter that supports up to
eight 1-inch
SCSI hard-disk drives via a SCSI backplane board. The SCSI backplane automatically
configures SCSI ID numbers and SCSI termination on individual hard-disk drives, greatly
simplifying drive installation.
- 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 Dell OpenManage™ Server Agent software
package.`
- Two PS/2-style keyboard and mouse ports, and dual USB ports.
The following software is included in the system:
- Video drivers for displaying many popular application programs in high-resolution modes.
For more information on these drivers, see the User's Guide.
- 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" in the User's Guide.
- The System Setup program for quickly viewing and changing the
system configuration information.
- Enhanced security features, including a user password and a supervisor password, are
available through the System Setup program.
The system includes the following service features to make troubleshooting and repair easy and effective, in most cases without tools or service aids:
- Dell Diagnostics are available on the Utility
partition, which checks for hardware problems (if the system
can boot). The Dell Diagnostics can be downloaded to
diskettes from the Dell OpenManage Server Assistant CD.
- Embedded server management hardware, which monitors temperatures and
voltages throughout the system and notifies you if the system overheats, if a system
cooling fan malfunctions, if a processor overheats, or if a power supply or
VRM fails.
The system chassis simplifies removing and replacing system
components. You can replace microprocessors or DIMMs without removing the system board.
The Dell-designed SCSI backplane board and hard-disk drive carriers eliminate the
extensive cabling and drive configuration usually required for a SCSI subsystem.
