With the installation of a second processor Slot 2 SEC cartridge in the secondary Slot 2 SEC cartridge connector on the system board, the computer
becomes a dual-processing system. The second processor must be the same
type and frequency as the first processor. To take advantage of two processors, dual-processing systems must have multiprocessing operating systems,
such as the Microsoft ® Windows NT ® 4.0 operating system.

The Dell Precision 610 mini tower systems offer advanced expansion subsystems that can support a mixture of traditional ISA expansion cards (called
legacy cards), Plug and Play ISA expansion cards, PCI expansion cards, and a
2X AGP card. The operating system or the ISA Configuration Utility (ICU),
included with the system, provides a means of avoiding resource conflicts that
might arise from such an arrangement.
1-4
Dell Precision 610 Mini Tower Systems Service Manual
After all legacy cards have been configured by the operating system or with
the ICU, the computer automatically assigns any required memory space, IRQ
lines, and DMA channels to any installed Plug and Play ISA expansion cards
and PCI expansion cards the next time the computer is rebooted. Chapter 4,
“Using the ISA Configuration Utility,” in the Dell Precision WorkStation 610 Mini
Tower Systems User’s Guide describes the ICU and provides instructions for
using it to configure the computer.
There are seven expansion-card connectors (see Figure 1-4) on the system
board. Expansion-card connectors PCI1 through PCI5 support 32-bit PCI
expansion cards; expansion-card connector AGP supports a 32-bit 2X AGP
expansion card; and expansion-card connector ISA1 can accommodate an 8- or
16-bit ISA expansion card.
NOTES: Connector ISA1 shares expansion-slot space with connector PCI5.
Therefore, only one card of either type can be installed in this slot.
PCI4 has a connector extension to support a PCI RAID controller (see
Figure 1-11 for the location of the PCI connectors).

+DUG'LVN'ULYH2SWLRQV
Dell Precision 610 mini tower systems have eight drive bays for installing the
following types of drives (see Figure 1-5):
‡ The externally accessible drive bays at the front of the computer consist of
one 3.5-inch drive bay (dedicated to a 3.5-inch slimline diskette drive) and
three 5.25-inch drive bays that can hold up to three half-height, 5.25-inch
devices—typically tape drives or CD-ROM drives. Alternately, 3.5-inch
devices can be installed in the 5.25-inch bays using adapters available from
Dell.
‡ The four-bay hard-disk drive cage below the externally accessible bays can
hold up to four 1-inch or up to two 1-inch and two 1.6-inch hard-disk drives
installed vertically. The maximum number of hard-disk drives must be
either two EIDE hard-disk drives or up to four SCSI hard-disk drives.
NOTE: For detailed information about installing SCSI devices, see Chapter 10,
“Installing Drives,” in the User’s Guide.

The enhanced dual-interface EIDE subsystem supports two EIDE interfaces
(primary and secondary), each of which can support up to two EIDE devices.
The EIDE controller resides on the high-speed PCI bus.
The primary EIDE interface (IDE1) provides support for up to two highperformance EIDE devices. The computer’s boot drive should be connected to
the primary EIDE interface.
The secondary EIDE interface (IDE2) also provides support for up to two highperformance EIDE devices, typically EIDE tape drives or CD-ROM drives.

Dell Precision 610 Mini Tower Systems Service Manual
NOTE: The externally accessible drive bays at the front of the computer are
normally used for diskette drives, CD-ROM drives, and/or tape drives. Harddisk drives should be installed in the internal hard-disk drive positions
described in “Hard-Disk Drive Options” found earlier in this chapter. For detailed
information about the data storage subsystem, see Chapter 10, “Installing Drives,”
in the User’s Guide.
6&6,6XSSRUW
SCSI drives are supported by using two integrated SCSI channels:
‡ The primary (Adaptec AIC-7890) channel provides Ultra2/Wide LVD
(80-MB/sec) support for high-performance SCSI hard-disk drives and an
optional RAID subsystem.
NOTE: To achieve 80-MB/sec support, all of the installed SCSI devices
must support the Ultra2 specification’s 80-MB/sec transfer rate. If they do
not, the transfer rate will default to the speed of the slowest device in the
SCSI chain.
‡ The secondary (Adaptec AIC-7880) channel provides internal Ultra/Narrow
and external Ultra/Wide (40-MB/sec) support for SCSI CD-ROM and tape
drives, optical drives, scanners, and so forth.
$XGLR&RQWUROOHU
The system board has an onboard 16-bit Crystal CS4237B audio controller chip
and connectors on the back panel for connecting the computer to external
audio devices such as speakers/headphones and microphone. The controller
supports all sound functions contained on the Sound Blaster Pro expansion
card from Creative Laboratories, Inc.
Chapter 6, “Using the Integrated Audio Controller,” in the User’s Guide provides instructions for connecting the computer to external audio devices and

The video subsystem consists of either a high-speed, high-resolution 2X AGP
or a PCI graphics adapter card. (For more information, see the documentation
that came with the graphics adapter card.) AGP greatly improves graphics performance by providing a dedicated bus for a faster interface between the video
subsystem and system memory. AGP also allows conventional memory to be
used for video-related tasks.

Dell Precision 610 mini tower systems contain an integrated 10/100-Mbps
3Com PCI 3C905b-TX NIC (uses a 3Com 3C917 application-specific integrated
circuit [ASIC]). The NIC subsystem connects to the Ethernet network through
a single RJ45 connector on the back panel of the computer.
System Overview
1-7
The 10/100-Mbps NIC supports a 10-Mbps direct connection to either a
Category 3 or a Category 5 Ethernet cable. When the NIC operates in the
100-Mbps mode, a Category 5 Ethernet cable must be used.
Chapter 5, “Using the Network Interface Controller,” in the User’s Guide provides instructions for connecting the computer to, and configuring it for use
on, an Ethernet network.

USB capability simplifies connection of peripheral devices such as mice, printers, and computer speakers. The USB connectors on the computer’s back
panel provide a single connection point for multiple USB-compliant devices.
USB-compliant devices can be connected and disconnected while the computer is running.

If a processor or hard-disk drive exceeds its recommended operating temperature range, a system event triggers a system management interrupt (SMI),
which alerts the BIOS. If the Dell ThermalShutdown Service is installed, the
power indicator flashes and a message appears on the monitor to alert the
user that the system will shut down in an orderly manner, preventing the loss
of data. If the service is unable to shut down the system within approximately
3 minutes, the BIOS powers down the computer. If the ThermalShutdown Service is not installed, the computer turns off immediately.
NOTE: The BIOS powers down the computer in the event of a thermal alert
only if the Thermal Power-Off category is set to ENABLED in the System Setup
program.

The 330-W system power supply can operate from an AC power source of
115 VAC at 60 Hz or 230 VAC at 50 Hz. The system power supply provides the
DC operating voltages and currents listed in Table 1-1.
NOTE: The power supply produces DC voltages only under its loaded condition. Therefore, when you measure these voltages, the DC power connectors
must be connected to their corresponding power input connectors on the system board or drives.

There is no requirement that one socket be filled before the other, and empty
sockets can be left between installed DIMMs. However, Dell recommends
populating the sockets in consecutive order starting with DIMM A. DIMM
sockets do not have to contain DIMMs of the same size. DIMMs may be
installed in any order.

To ensure that the chips are fully seated in their sockets, press firmly on
the top of each chip.
To reseat the microprocessor, remove and reinstall it as described in
“Microprocessor Slot 2 SEC Cartridge/Heat Sink Assembly” in Chapter 4.
To reseat a DIMM, remove it from its socket and reinstall it as described in
“DIMMs” in Chapter 4.
If you need to reseat an expansion card, use a 1/4-inch nut driver to
remove the screw that secures the card-mounting bracket. Grasp the card
by its top corners, and carefully pull it out of its connector. Reinsert the
card in its connector, and carefully push it in until it is fully seated. Then
reinstall the card-mounting bracket’s retaining screw (see “Expansion

Devices within or connected to the computer may require dedicated memory
spaces, interrupt levels, or DMA channels, all of which must be allocated during installation of the devices. Because devices may be installed at different
times, it is possible that the same resource is assigned to two or more
devices.
Resource conflicts can result in disorderly or erratic system operation or failure
of the system to operate at all. If you suspect that resource conflicts might
exist, check the system using the Windows NT Diagnostics in the
2-6
Dell Precision 610 Mini Tower Systems Service Manual
Administrative Tools folder or the ISA Configuration Utility (ICU), and reassign
the resources as necessary. See “Advanced Expansion Subsystem” in
Chapter 1 for information on the Device Manager and the ICU. See “Interrupt
Request Assignments” in Chapter 1 to help identify possible conflicts. Also
review the documentation provided with any installed expansion cards and
other devices for additional interrupt information for the specific devices.

To start the Dell Diagnostics, turn off the system, insert a diagnostics diskette
into drive A, and then turn on the system.
Starting the diagnostics causes the Dell logo screen to appear on the monitor
screen, followed by a message indicating that the diagnostics is loading.
Before the diagnostics loads, a program tests the portion of main memory
(RAM) required for loading the diagnostics. If a RAM error is detected, a message appears on the screen telling you which DIMM has failed.
If no errors are found in RAM, the diagnostics loads and the Diagnostics Menu
appears. This menu lets you choose the following options or exit to the
MS-DOS® prompt:
‡ Run Quick Tests — Runs selected tests from all test groups to quickly
locate a failure or to indicate where further testing is needed to isolate a
failure
‡ Run All Tests — Runs all tests for a thorough test of the system
‡ Run Specific Tests — Tests a particular area or subsystem

If none of the troubleshooting procedures in this chapter or the tests in the
Dell Diagnostics reveals the source of the problem or leads to the proper
troubleshooting steps for determining the source of the problem, call Dell for

This chapter describes beep codes and system error messages that can occur
during system start-up or, in the case of some failures, during normal system
operation. The tables in this chapter list faults that can cause a beep code or
system error message to occur and the probable causes of the fault in each
case.
If a faulty system does not emit beep codes or display system error messages
to indicate a failure, you should run the appropriate tests in the Dell Diagnostics to help isolate the source of the problem. See “Running the Dell
Diagnostics” in Chapter 2.

If the monitor cannot display error messages during the POST, the system may
emit a series of beeps that identifies the problem or that can help you identify
a faulty component or assembly. Table 3-1 lists the beep codes that may be
generated during the POST. Most beep codes indicate an error that may prevent the system from completing the boot routine until the indicated condition
is corrected. If the table does not lead to the source of the problem, run the
appropriate tests in the Dell Diagnostics to assist in troubleshooting the
problem.

Before you reinstall the cover, fold all cables out of the way so that they do not
interfere with the cover or with the proper airflow inside the computer.
When you boot the system, you will need to reset the chassis intrusion detector by entering the System Setup program and changing the Chassis Intrusion
setting to Not Detected. See Appendix A for information on the System Setup
program. If you need further information, see Chapter 3, “Using the System
Setup Program,” in the User’s Guide.
NOTES: After removing and replacing the cover, the chassis intrusion detector
will cause the following message to be displayed at the next system start-up:
ALERT! Cover was previously removed.
If a setup password has been assigned by someone else, contact the network
administrator for information on resetting the chassis intrusion detector.

If you are replacing more than one hard-disk drive in the bracket, do not fully
tighten any of the screws that hold the drives in the bracket until all of the
drives have been placed into the bracket. This prevents the bracket from compressing, which could make it difficult to insert additional drives.
When you replace the hard-disk drive bracket, be sure that it is pushed fully
into the system and snapped into position before you close the drive cage door
(See Figure 4-13).
When you are ready to replace the front bezel, be sure to fold the drive cage

To install a Slot 2 SEC cartridge/heat sink assembly, press the cartridge firmly
into its connector until it is firmly seated. You must use up to 25 pounds of
force to fully seat the cartridge in its connector. Place the top bracket on top of
the cartridge. Install the four large thumbscrews through the top bracket holes
and through the holes in the guide bracket assembly to secure the heat sink to
the system board.
NOTE: Both processor slots must be populated with either a Pentium II Xeon
processor or a Dell terminator card. If a slot is not occupied, or if a non-Dell terminator card is installed, the system will not power on.
If necessary, change the processor speed jumper setting (see Figure 4-17 to
locate system board jumpers).
The processor speed jumper should be set for the installed processor’s rated
internal speed. For example, for a 400-MHz Intel Pentium II Xeon processor, a
jumper plug should be installed on the pins labeled “400MHZ.” (See Chapter 1,
“System Board Jumpers,” for more information on the jumpers.) The processor
speed jumper setting must not exceed the slowest internal speed of either
processor.
