Installing Drives: Dell Precision WorkStation 410 Desktop Systems
Installing Drives: Dell™ Precision™ WorkStation 410 Desktop Systems
Your Dell computer has five drive bays for installing the following types of
drives (see Figure 10-1):
- 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 diskette drive) and two 5.25-inch
bays that can hold up to two 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 two-bay hard-disk drive cage next to the accessible bays can hold up to
two 1.6-inch hard-disk drives installed vertically. The drives must be
either enhanced integrated drive electronics (EIDE) hard-disk drives or
small computer system interface (SCSI) hard-disk drives.
The next three sections contain information that you will need in several of
the installation procedures described later in the chapter. The remaining
sections of this chapter cover each type of drive installation.
 |
NOTES:
In all of the following
procedures, left and right refer to your left
and right as you face the front of the computer.
Because of the length of the bay, you can only ins
tall tape backup units or ZIP drives in the lower 5.25-inch bay. You can
install a CD-ROM only in the top 5.25-inch bay. |
Empty drive bays contain a front-panel insert to protect the inside of the
computer from dust particles and also to ensure proper airflow within the
computer. Before you install a drive in an empty drive bay, you must first
remove the front-panel insert.
To remove the insert covering a 5.25-inch bay, follow these steps:
-
Turn off the system, including any attached peripherals, and disconnect all
the AC power cables from their power sources.
-
Remove the computer cover as instructed in "Removing the Computer Cover".
-
With your thumbs, press in on each end of the insert until the insert snaps
free of the cover (see Figure 10-2).
Figure 10-2. Removing the Front-Panel Insert for a 5.25-Inch Bay
To replace a front-panel insert for a 5.25-inch bay, work from inside the
cover. Insert the two ring-tabs (one on each end of the insert) over the
posts on the inside of the bay opening, and firmly press both ends of the
insert into place (see Figure 10-2).
When installing a drive, you connect two cables-a DC power cable
and an interface cable - to the back of the drive. Your drive's power input connector (to which you
connect the DC power cable) resembles the connector shown in Figure 10-3.
Figure 10-3. DC Power Cable Connector
The drive's interface connector is a card-edge connector or a header
connector, as shown in Figure 10-4.
Figure 10-4. Drive Interface Connectors
When attaching the interface cable to a drive, be sure to match the colored
strip on the cable to pin 1 of the drive's interface connector. For the
location of pin 1 on the drive's interface connector, see the documentation
that came with the drive.
When disconnecting an interface cable from the system board, be sure to press
in on the locking tabs on the cable connector (if any) before disconnecting
the cable. When attaching an interface cable to the system board, be sure
that the locking tabs snap into place, ensuring that the cable is firmly
attached to the connector on the system board.
Most interface connectors are keyed for correct insertion; that is, a notch
or a missing pin on one connector matches a tab or a filled-in hole on the
other connector (see Fig-ure 10-4). Keying ensures that the pin-1 wire in
the cable (indicated by the colored strip along one edge of the cable) goes
to the pin-1 end of the connector.
The pin-1 end of a connector on a board or a card is usually indicated by a
silk-screened "1" printed directly on the
board or card.
 |
CAUTION:
When connecting an interface
cable, do not reverse the interface
cable (do not place the colored strip away from pin 1 of the connector).
Reversing the cable prevents the drive from operating and could damage the
controller, the drive, or both. |
The upper 5.25-inch drive can accommodate any of the following types of
half-height drives:
- A CD-ROM or tape drive that uses the secondary EIDE interface or the
secondary SCSI interface on the system board
- Any 5.25-inch device that uses its own controller card
Because of the length of the bay, the lower 5.25-inch drive bay can only accommodate tape backup units
or ZIP drives.
|
|
NOTE:
For information on
configuring, connecting, and installing SCSI drives,
see "Installing SCSI Devices"
found later in this chapter. |
To install a drive in a 5.25-inch drive bay, follow these steps:
- Unpack the drive and prepare it for installation.
|
CAUTION:
Ground yourself by touching an
unpainted metal surface on the back
of the computer. |
Check the documentation that accompanied the drive to verify that the drive
is configured for your computer system. Change any settings necessary for
your configuration.
If you are installing an EIDE CD-ROM or EIDE tape drive, configure the drive
for the cable select setting.
If you are installing a SCSI device, make sure the device has termination
disabled. See "Installing SCSI Devices"
found later in this chapter.
- Remove the computer cover as instructed in
"Removing the Computer Cover".
|
CAUTION:
See
"Protecting Against Electrostatic Discharge" in the
safety instructions at the front of this guide. |
- Remove the drive bracket from the bay you want to use.
Squeeze the metal tabs that extend from each side of the drive bracket toward
each other, and pull the bracket out of the bay (see Figure 10-5).
If a drive is already installed in the bay and you are replacing it, be sure
to disconnect the DC power cable and interface cable from the back of the
drive before sliding the bracket out of the bay. To remove the old drive
from the bracket, unscrew the four screws that secure the drive to the
bracket (see Figure 10-6).
- Attach the bracket to the new drive.
Locate the four screw holes around the drive's perimeter. Fit the bracket
over the drive, and then tilt the front of the drive up so that the bracket
drops down into place. To ensure proper installation, all screw holes should
be aligned and the tabs on the front of the bracket should be flush with the
front of the drive (see Figure 10-6).
Figure 10-6. Attaching the Drive Bracket to the New Drive
To further ensure proper positioning of the drive in the chassis, insert and
tighten all four screws in the order in which the holes are numbered (the
holes are marked "1" through "4").
- Slide the new drive into the drive bay until it snaps securely into place
(see Figure 10-7).
Make sure that both bracket tabs snap into place in the drive bay.
Figure 10-7. Inserting the New Drive Into the Drive Bay
- If you are installing a drive that has its own controller card, install the
controller card in an expansion slot.
See "Installing an Expansion Card".
- Connect a DC power cable to the power input connector on the back of the
drive (see Figure 10-8).
Figure 10-8. Attaching EIDE Tape Drive Cables
- Connect the appropriate interface cable to the interface connector on the
back of the drive (see Figure 10-8).
If your system came with an EIDE CD-ROM or tape drive, use the spare
connector on the existing interface cable. Otherwise, use the EIDE or SCSI
cable provided in the drive kit.
|
CAUTION:
You must match the colored strip
on the cable with pin 1 on the
drive's interface connector to avoid possible damage to your system. |
- For an EIDE tape drive or CD-ROM drive, connect the other end of the
interface cable to the interface connector labeled "IDE2" on the
system board (see
Figure 9-1).
For a SCSI drive, connect the cable from the drive to the interface connector
labeled "SCSI_NARROW" on the system board.
For a diskette drive, connect the cable from the drive to the interface
connector labeled "DISKETTE" on the system board.
For a drive that comes with its own controller card, connect the other end of
the interface cable to the controller card.
Check all cable connections. Fold cables out of the way to provide airflow
for the fan and cooling vents.
- If the 5.25-inch drive bay was previously empty, remove the front-panel
insert from the front cover.
See
"Removing and Replacing Front-Panel Inserts"
found earlier in this chapter.
- Replace the computer cover, and reconnect your computer and peripherals to
their power sources and turn them on.
|
|
NOTE:
After you remove and replace
the chassis, the chassis intrusion
detector will cause the following message to be displayed at the next system
start-up: |
ALERT! Cover was previously removed.
- To reset the chassis intrusion detector, enter the System Setup program and
reset Chassis Intrusion to Not Detected.
See "Using the System Setup Program", for instructions.
|
|
NOTE:
If a setup password has been
assigned by someone else, contact your
network administrator for information on resetting the chassis intrusion
detector. |
- Update your system configuration information.
For a diskette drive, update the appropriate Diskette Drive category (A or B)
on Page 1 of the System Setup screens to reflect the size and capacity of
your new diskette drive. (For more information, see
"Using the System Setup Program".)
For EIDE CD-ROM and tape drives, set the appropriate Drive category (0 or 1)
under Drives: Secondary to Auto.
- Verify that your system works correctly.
See your Diagnostics and Troubleshooting Guide for information on running the
Dell Diagnostics and troubleshooting any problems that may occur. Use the
following guidelines to determine which test to use:
- If you installed a diskette drive, test it by running all of the subtests in
the Diskette Drives Test Group of the Dell Diagnostics.
- If you installed a CD-ROM drive, see the documentation that came with the
drive for instructions on loading device drivers and using the drive. If it
is an EIDE CD-ROM drive, test it by running all of the subtests in the
IDE CD-ROM Drives Test Group of the Dell Diagnostics.
- If you installed a tape drive, perform a tape backup and verification test
with the drive as instructed in the tape-drive software documentation that
came with the tape drive.
|
|
NOTE:
The tape drives sold by Dell
come with their own operating software and
documentation. After you install a tape drive, refer to the documentation
that came with the drive for instructions on installing and using the tape
drive software. |
This section includes information on installing, partitioning, and formatting
EIDE hard-disk drives. For instructions on installing, partitioning, and
formatting SCSI hard-disk drives, see
"Installing SCSI Devices"
found later in this chapter.
Up to two 1.6-inch EIDE drives can be installed in the internal hard-disk
drive cage that is next to the externally accessible 5.25-inch drive bays.
All EIDE devices should be configured for the cable select jumper position,
which assigns master and slave status to devices by their position on the
EIDE cable. When two EIDE devices are connected to a single EIDE cable and
are configured for the cable select jumper position, the device attached to
the last connector on the interface cable is the master or boot device
(drive 0) and the device attached to the middle connector on the interface
cable is the slave device (drive 1). Refer to the drive documentation in
your upgrade kit for information on setting devices to the cable select
jumper position.
With the two EIDE interface connectors on the system board, your system can
support up to four EIDE devices. EIDE hard-disk drives should be connected
to the EIDE interface connector labeled "IDE1." (EIDE tape drives
and CD-ROM drives should be connected to the EIDE interface connector
labeled "IDE2.")
Install an EIDE hard-disk drive in the hard-disk drive bracket as follows:
- If you are replacing a hard-disk drive that contains data you want to keep,
be sure to make a backup of your files before you continue with this
procedure.
- Prepare the drive for installation.
|
CAUTIONS:
Ground yourself by touching an unpainted metal surface on the back
of the computer.
When you unpack the drive, do not set it on a hard surface, which may damage
the drive. Instead, set the drive on a surface, such as a foam pad, that
will sufficiently cushion it. |
Check the documentation that accompanied the drive to verify that it is
configured for your computer system.
Figure 10-9. Removing the Hard-Disk Drive Bracket
- Remove the drive bracket from the chassis.
If any hard-disk drives are already installed in the bracket, disconnect the
DC power cable and interface cable from each drive.
Remove the screw holding the drive bracket to the drive bay. Lift up on the
drive bracket to disengage it from the latch on the drive bay and the three
hooks on the front of the chassis (see Figure 10-9). Remove the bracket.
- Slide the drive into the chosen bay of the bracket, orienting it so that the
connectors on the back of the drive face the inside of the chassis when the
bracket is reinstalled and so that the drive is in the left-most position in
the bracket (see Figure 10-10).
You must install a drive in the primary drive bay. The primary drive bay is
the left-most bay in the bracket and is marked as "HD1" on the top
surface of the bracket. The secondary drive bay is marked as "HD2."
- Align the four screw holes of the drive and bracket. Insert and tighten the
screws that came with your upgrade kit.
Use the four screw holes in the top and bottom of the bracket (see
Figure 10-10) to secure the installed hard-disk drive(s).
Figure 10-10. Inserting a 1-Inch Hard-Disk Drive Into the Bracket
- Reinstall the hard-disk drive bracket into the chassis (see Figure 10-11).
Insert the bracket into the chassis by inserting the hooks in the slots on
the front of the chassis. Then lower the bracket to the bottom of the
chassis, making sure that the latch on the drive bay is engaged. Replace the
screw holding the drive bracket to the drive bay.
Figure 10-11. Inserting the Hard-Disk Drive Bracket Into the Chassis
- Connect a DC power cable to the power input connector on the back of the
drive (see Figure 10-12).
Check all connectors to be certain that they are properly cabled and firmly
seated.
- Connect one of the device connectors on the EIDE cable to the 40-pin
interface connector on the back of the hard-disk drive (see Figure 10-12).
|
CAUTION:
You must match the colored strip
on the EIDE cable with pin 1 on the
drive's interface connector to avoid possible damage to your system. |
Figure 10-12. Attaching Hard-Disk Drive Cables
- If the other end of the EIDE cable is not already connected, connect it to
the IDE1 connector on the system board.
|
CAUTION:
You must match the colored strip
on the EIDE cable with pin 1 on the
IDE1 connector to avoid possible damage to your system. |
To locate the IDE1 connector, see Figure 9-1.
- Replace the computer cover. Then reconnect your computer and peripherals to
their power sources, and turn them on.
|
|
NOTE:
After you remove and replace
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.
- Insert a bootable diskette (such as the Dell Diagnostics Diskette) into drive
A.
- Enter the System Setup program, and update the appropriate Drive category (0
or 1) under Drives: Primary.
See "Drives: Primary and Secondary".
- While in the System Setup program, reset the chassis intrusion detector by
changing Chassis Intrusion to Not Detected.
See "Using the System Setup Program", for instructions.
|
|
NOTE:
If a setup password has been
assigned by someone else, contact your
network administrator for information on resetting the chassis intrusion
detector. |
After you update the System Setup settings, reboot the system.
- Partition and logically format your drive, as described in the next
subsection, before proceeding to the next step.
- Test the hard-disk drive by running the Hard-Disk Drives (Non-SCSI) Test
Group in the Dell Diagnostics.
See your Diagnostics and Troubleshooting Guide for information on running the
diagnostics and troubleshooting any problems that may occur.
- Install your operating system on the hard-disk drive.
Refer to the documentation that came with your operating system.
EIDE hard-disk drives must be physically formatted, partitioned, and
logically formatted before they can be used to store data. Every hard-disk
drive from Dell is physically formatted before it is sent to you.
|
|
NOTE:
When using the Windows NT
operating system with the FAT 16 file system,
the primary partition for each hard-disk drive can be no larger than 2
gigabytes (GB). Extended partitions can be larger than 2 GB, but each
logical drive within an extended partition must be no larger than 2 GB. |
To partition and logically format your hard-disk drive, use the program(s)
offered by your operating system.
This section describes how to configure and install SCSI devices in your Dell
Precision 410 system.
Although SCSI devices are installed essentially the same way as other devices,
their configuration requirements are different. For details on configuring
your particular SCSI subsystem, refer to the documentation that came with
your SCSI devices and/or your host adapter card. The following subsections
offer some general guidelines.
Internal SCSI devices attached to the integrated Adaptec 7890 Ultra2/Wide low
voltage differential (LVD) controller through the 68-pin primary SCSI
connector on the system board must have a unique SCSI ID number from 0 to 15.
Externally accessible SCSI devices attached to the integrated Adaptec 7880
Ultra/Wide controller through the 50-pin Narrow SCSI connector on the system
board must have a unique SCSI ID number from 0 to 7.
External SCSI devices connected to the integrated Adaptec 7880 Ultra/Wide
controller through the 68-pin Ultra/Wide SCSI connector on the system back
panel must have a unique SCSI ID number from 0 to15. This SCSI ID number
cannot conflict with any SCSI ID number already assigned to a SCSI device
connected to the 50-pin internal SCSI connector on the system board.
When SCSI devices are shipped from Dell, the default SCSI ID numbers for the
primary and secondary controllers are assigned as follows:
- Primary SCSI controller:
- The primary 7890 Ultra2/Wide LVD SCSI controller is configured through the
computer's basic input/output system (BIOS) as SCSI ID 7.
- The first internal SCSI hard-disk drive is configured as SCSI ID 0. (The
drive used to boot your system should always be configured as SCSI ID 0.)
- Secondary SCSI controller:
- The secondary 7880 Ultra/Wide SCSI controller is configured through the
computer's BIOS as SCSI ID 7.
- A SCSI CD-ROM drive is configured as SCSI ID 5.
- A SCSI tape drive or digital audio tape (DAT) drive (if installed) is
configured as SCSI ID 6.
|
|
NOTE:
There is no requirement that
SCSI ID numbers be assigned sequentially
or that devices be attached to the cable in order by ID number.
|
SCSI devices installed by Dell are configured correctly during the
manufacturing process. You do not need to set the SCSI ID for these SCSI
devices.
If you attach additional optional SCSI devices, refer to the documentation
that came with each device for information about setting the appropriate
SCSI ID number.
|
CAUTION:
Dell recommends that you use
only SCSI cables purchased from Dell.
SCSI cables purchased elsewhere are not guaranteed to work with Dell
Precision 410 systems. |
SCSI logic requires that termination be enabled for the two devices at
opposite ends of the SCSI chain and disabled for all devices in between.
However, because both SCSI controllers are self-terminating and because all
internal SCSI cables provided by Dell have active termination at the end of
the cables, any SCSI devices you install should have termination disabled on
the devices.
Furthermore, when attaching external SCSI devices, you should use only
external SCSI cables with active termination on the cable. When used with
this type of cable, all external SCSI devices also need to have termination
disabled on the devices.
See the documentation provided with any optional SCSI device you purchase for
information on disabling termination on the device.
The 68-pin (internal) SCSI cable in your Precision 410 system connects SCSI
devices (normally SCSI hard-disk drives) to the 7890 Ultra2/Wide LVD
controller.
- The connector at the end of the cable attaches to the Ultra2/Wide LVD primary
SCSI controller connector labeled "SCSI_ULTRA2" on the system
board.
- The other connectors on the cable are used for attaching up to two
SCSI hard-disk drives in the internal drive bays (see Figure 10-13).
The 50-pin (internal) Narrow SCSI cable connects SCSI devices to the 7880
Ultra/Wide controller.
- The narrow connector at the end of the cable attaches to the secondary SCSI
controller connector labeled "SCSI_NARROW" on the system board.
- The other connectors on the cable are used for attaching SCSI devices
installed in the externally accessible drive bays (see Figure 10-13).
An optional shielded external cable with a 68-pin connector is used for
attaching an external SCSI device to the 7880 external SCSI connector on the
system back panel.
Refer to the documentation that came with the external SCSI device for
information on how to connect the device, set its SCSI ID, and disable
termination.
Configure and install one or more SCSI devices in your computer as follows:
- Determine which connector on the internal SCSI cable you will attach to each
SCSI device.
See "SCSI Configuration Guidelines"
found earlier in this section.
- Unpack each SCSI device and prepare it for installation.
|
CAUTIONS:
Ground yourself by touching an unpainted metal surface on the back
of the computer.
When you unpack the drive, do not set it on a hard surface, which may damage
the drive. Instead, set the drive on a surface, such as a foam pad, that
will sufficiently cushion it. |
Configure the device for a SCSI ID number and disable termination, if
necessary. For instructions, see the documentation that came with the SCSI
device as well as "SCSI Configuration Guidelines" found earlier in
this section.
- Install the SCSI devices as appropriate.
- To install a SCSI hard-disk drive, complete steps 3 through 9 of
"Installing an EIDE Hard-Disk Drive in the Internal Hard-Disk Drive Bracket" found earlier in this chapter. Then continue with step 4 of this
procedure.
- To install a SCSI tape drive, CD-ROM drive, or DAT drive, complete steps 2
through 5 of
"Installing a Drive in a 5.25-Inch Drive Bay"
found earlier in this chapter. Then continue with step 4 of this procedure.
- To install an external SCSI device, continue with step 4 of this procedure.
- If you are installing a SCSI host adapter card, configure the card and
install it in an empty expansion slot (see
"Installing an Expansion Card".)
If you attach any SCSI hard-disk drives to the
host adapter card, connect the hard-disk drive access cable to the SCSI host
adapter card and to the AUX LED connector on the system board (see
Figure 9-1).
- Attach the SCSI cable to each SCSI device.
For additional instructions on connecting SCSI devices, see
"SCSI Cables"
found earlier in this section.
If you are installing an internal SCSI device, firmly press the SCSI cable's
header connector onto the 50- or 68-pin connector on the back of the device.
|
CAUTION:
You must match the colored strip
on the cable with pin 1 on the
drive's interface connector to avoid possible damage to your system. |
The connectors on Narrow SCSI cables are keyed for proper positioning-a
raised area on the outside of the header connector fits into a notch on the
device connector. The connectors on Wide SCSI cables are shaped so that they
can be attached one way only.
If you are installing an external SCSI device, connect one end of the
external SCSI cable to the SCSI bus connector on the back of the device.
Attach the other end of the external SCSI cable to the SCSI connector on the
system back panel.
|
|
NOTE:
Dell offers an external SCSI
68-pin-to-50-pin adapter kit for
connecting SCSI-3 devices to the SCSI-2 connector on the Precision 410
system back panel. Contact your Dell sales representative for more
information. |
- Connect the SCSI device(s) to a power source.
- If you are installing an internal SCSI device, connect a DC power cable to
the power input connector on the SCSI device.
- If you are installing an external SCSI device, connect the socket end of the
power cable into the AC power receptacle on the back of the SCSI device.
Connect the other end of the power cable into a standard electrical wall
outlet.
Check all other cable connections. Fold all internal cables out of the way to
provide airflow for the fan or cooling vents.
- If you installed an externally accessible device, remove the front-panel
insert for the drive bay.
For instructions, see "Removing and Replacing Front-Panel Inserts"
found earlier in this chapter.
- Replace the computer cover. Then reconnect your computer and peripherals to
their power sources, and turn them on.
|
|
NOTE:
After you remove and replace
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.
- To reset the chassis intrusion detector, enter the System Setup program and
reset Chassis Intrusion to Not Detected.
See "Using the System Setup Program",
for instructions.
|
|
NOTE:
If a setup password has been
assigned by someone else, contact your
network administrator for information on resetting the chassis intrusion
detector. |
- If necessary, update the drive system configuration information in the System
Setup program.
For any SCSI devices, the respective category under Drives: Primary or Drives:
Secondary should be set to None. For instructions, see
"Using the System Setup Program".
- If you installed a SCSI hard-disk drive, partition and format the drive. Then
install the operating system.
For instructions, see the next subsection, "Partitioning and Formatting
SCSI Hard-Disk Drives," and your operating system documentation.
- Test the SCSI devices.
Test a SCSI hard-disk drive by running the SCSI diagnostics. See your
Diagnostics and Troubleshooting Guide for information on running the Dell
Diagnostics and troubleshooting any problems that may occur.
To test a SCSI tape drive, refer to the documentation for the tape drive
software to perform a tape drive backup and verification test.
You may need to use different programs than those provided with the operating
system to partition and format SCSI hard-disk drives. Refer to the
documentation that came with your SCSI software drivers for information on
installing the appropriate drivers and preparing your SCSI hard-disk drive
for use.
|
|
NOTE:
When using the Windows NT
operating system with the FAT 16 file system,
the primary partition for each hard-disk drive can be no larger than 2 GB.
Extended partitions can be larger than 2 GB, but each logical drive within
an extended partition must be no larger than 2 GB. |
