Your Dell computer has six drive bays for installing the following types of drives (see Figure 1):
The next three sections contain information that you will need in several installation procedures. The remaining sections cover each type of drive installation.
 |
NOTE: In all of the following
procedures, left and right refer to your left and right as you face the front
of the computer.
|
Figure 1. Drive Locations
|
The bezel is secured to the front of the chassis by two tabs and two hooks. The tab release for the bezel is at the top of the computer chassis and can be accessed only with the computer cover removed (see "Removing the Computer Cover"). With the cover removed, release the bezel by pressing the tab release marked with the icon (see Figure 2).
Figure 2. Removing the Front Bezel
|
While pressing the tab release, tilt the bezel away from the chassis, disengage the two retaining hooks at the bottom of the bezel, and carefully pull the bezel away from the chassis.
To replace the bezel, fit the two retaining hooks on the bezel into their corresponding slots at the bottom of the chassis. Then rotate the top of the bezel toward the chassis until the top tabs snap into their corresponding slots on the bezel.
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:
 |
CAUTION: Before you remove the computer cover, see "Safety First — For You and Your Computer." |
Figure 3. 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 bezel. Position the insert behind the bay opening, insert the two ring-tabs (one on each end of the insert) over the posts on the inside of the opening, and firmly press both ends of the insert into place (see Figure 3).
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 4.
Figure 4. DC Power Cable Connector
|
The drive's interface connector is a card-edge connector or a header connector, as shown in Figure 5.
Figure 5. 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 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.
| NOTICE: 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. |
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 Figure 5). 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 card-edge connector is usually identified by a notch cut about a quarter of an inch from the end of the connector, as shown in Figure 5. A header connector is usually keyed by the omission of one of its pins (see Figure 5), with the corresponding hole filled in on the connector cable.
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.
The 5.25-inch drive bays can accommodate any of the following types of drives:
|
NOTE: For information on configuring, connecting, and installing SCSI drives, see "Installing SCSI Devices." |
|
CAUTION: To avoid the possibility of electric shock, turn off the computer and any peripherals, disconnect them from their electrical outlets, and then wait at least 5 seconds before you remove the computer cover. Also, before you install an expansion card, see "Safety First — For You and Your Computer." |
To install a drive in a 5.25-inch drive bay, follow these steps.
| NOTICE: 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 the drive is configured for your computer system. Change any settings necessary for your configuration.
|
NOTE: If you are installing a non-EIDE tape drive, check the documentation for the drive to determine the jumper or switch settings used to designate the drive as drive address DS4 (not DS2 or DS3 as may be indicated in the drive documentation). Unless the drive is already set to drive 4, reconfigure its jumper or switch setting (see "Jumpers.") |
If you are installing an EIDE CD-ROM or EIDE tape drive, configure the drive for the Cable Select setting.
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 6).
|
NOTE: For easier access inside the chassis, you may want to rotate the power supply out of the way temporarily. To do so, see "Rotating the
Power Supply Away From the System Board."
|
Figure 6. Removing a Drive
|
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, turn the drive/bracket assembly upside down and unscrew the four screws that secure the drive to the bracket (see Figure 7).
Turn the drive upside down and locate the four screw holes around its perimeter. Fit the bracket over the drive, and then tilt the drive (front upward) 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 7).
Figure 7. 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").
Make sure that both bracket tabs snap into place in the drive bay.
|
See "Installing an Expansion Card."
| NOTICE: 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.
|
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 cable provided in the drive kit.
Figure 9. Attaching Diskette Drive or Tape Drive Cables
|
For a diskette drive, connect the cable from the drive to the interface connector labeled "DSKT" 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.
See "Removing and Replacing Front-Panel Inserts."
If the bezel on your drive is not flush with the bezel on your computer, remove the drive and adjust the position of the drive on the bracket, making sure to insert and tighten the screws in the order marked. Replace the drive in the drive bay, and then replace the computer cover.
|
NOTE: If Enabled, the Chassis Intrusion option will cause the following message to be displayed at the next system start-up: ALERT! Cover was previously removed. |
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:
|
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."
Up to two EIDE drives (one of which must be 1 inch high or less) can be installed in the hard-disk drive bracket below the drive cage. The first EIDE drive is installed in the 1-inch (lower) drive bay labeled "HD1"; a second drive is installed in the 1.6-inch bay labeled "HD2."
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 interface 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.
|
NOTE: If you want to install a second
EIDE drive that is a different type from the first drive but you do not have the
specifications for the first drive, do one of the following:
|
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.")
|
CAUTION: To avoid the possibility of electric shock, turn off the computer and any peripherals, disconnect them from their electrical outlets, and then wait at least 5 seconds before you remove the computer cover. Also, before you install an expansion card, see "Safety First — For You and Your Computer." |
Install an EIDE hard-disk drive in the hard-disk drive bracket as follows:
NOTICE: 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 the drive is configured for your computer system. Change any settings necessary for your configuration.
|
NOTE: If you are installing a non-EIDE tape drive, check the documentation for the drive to determine the jumper or switch settings used to designate the drive as drive address DS4 (not DS2 or DS3 as may be indicated in the drive documentation). Unless the drive is already set to drive 4, reconfigure its jumper or switch setting (see "Jumpers.") |
If you are installing an EIDE CD-ROM or EIDE tape drive, configure the drive for the Cable Select setting.
If a hard-disk drive is already installed on the drive bracket, disconnect the DC power cable and EIDE cable from the drive.
Remove the screw securing the hard-disk drive bracket to the front wall of the chassis.
Grasp the bracket, and rotate it outward from the chassis until the sliding tab clears the slide rail on the drive cage (see Figure 10). Lift the bracket up slightly to free its hinge tabs from the chassis slots.
Figure 10. Removing the Hard-Disk Drive Bracket
|
If you are replacing a drive in the 1.6-inch slot, use the four screw holes in the side of the bracket (see Figure 11). If you are replacing a drive in the 1-inch slot, use the four screw holes in the bottom of the bracket.
Figure 11. Inserting a 1.6-Inch Hard-Disk Drive in the Bracket
|
Insert the bracket's hinge tabs into the chassis slots so that the tabs hook over the slots. Then rotate the bracket toward the drive cage, and fit the bracket's sliding tab on the drive-cage slide rail. Slide the bracket into place. Reinstall the screw you remove in step 4.
Figure 12. Inserting the Drive Bracket in the Chassis
|
NOTICE: 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 13. Attaching Hard-Disk Drive Cables
|
NOTICE: You must match the colored strip on the EIDE cable with pin 1 on the system board IDE connector to avoid possible damage to your system.
To locate the system board IDE connector, see "System Board Features."
Check all connectors to be certain that they are properly cabled and firmly seated.
|
NOTE: If the drive you just installed is the primary drive and no operating system is installed, you must start the computer using a bootable diskette or CD. |
|
NOTE: If Enabled, the Chassis Intrusion option will cause the following message to be displayed at the next system
start-up: ALERT! Cover was previously removed. |
After you update the System Setup options, reboot the system.
See your Diagnostics and Troubleshooting Guide for information on running the Dell Diagnostics and troubleshooting any problems that may occur.
Refer to the documentation that came with the 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: On systems with hard-disk drives
larger than 2 gigabytes (GB), create a primary partition of 2 GB and divide the remaining
capacity into partitions of 2 GB or less. For example, a system with a 2.5-GB hard-disk
drive would have a primary partition of 2 GB (drive C) and a second partition of 500
megabytes (MB) (drive D). Hard-disk drives must be partitioned this way because MS-DOS®-based operating systems (including Microsoft® Windows NT® when you use a file allocation table [FAT] 16 file system) do not support drive partitions larger than 2 GB. |
To partition and logically format your hard-disk drive, use the program(s) offered by your operating system.
For MS-DOS, use the fdisk and format commands to perform these procedures. The fdisk and format commands are described in the MS-DOS reference documentation.
| NOTICE: If you format your hard-disk drive under the OS/2 High Performance File System (HPFS), you cannot reformat the drive for MS-DOS without losing all HPFS data. See your OS/2 documentation for details. |
For the OS/2® operating system, see the discussion on partitioning and logical formatting in the documentation that came with the operating system.
| NOTICE: If you format your hard-disk drive under the Windows NT File System (NTFS), you cannot reformat the drive for MS-DOS without losing all NTFS data. See your Windows NT documentation for details. |
For Windows NT, see the discussion on partitioning and logical formatting in the documentation that came with the operating system.
For the UNIX® operating system, refer to your UNIX documentation.
To use SCSI devices in your Dell computer, you must have a SCSI host adapter card, which comes with its own SCSI cable. This cable can be used to attach a variety of SCSI devices (hard-disk drives, tape drives, and so on). The SCSI host adapter configures the devices attached to it as one subsystem, not as independent devices.
Although SCSI devices are installed essentially the same way as other devices, their configuration requirements are different.
For details on configuring your 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.
Each device attached to a SCSI host adapter card, as well as the card itself, must have a unique SCSI ID number from 0 to 7. When SCSI devices are shipped from Dell, the default SCSI ID numbers are assigned as follows:
|
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. |
The type of cabling you receive with your SCSI device depends on the type of device you are installing.
Before installing SCSI devices in your computer, you may need to configure the termination on your SCSI device(s). Both types of internal SCSI cables contain terminators on the device end of the cables, so the devices connected to these cables must have termination disabled (see Figure 14). External SCSI cables do not have terminators, so termination must be enabled on the SCSI device itself.
Figure 14. Internal SCSI Cables
|
| NOTICE: Do not connect devices to all three connectors (internal narrow connector, internal wide connector, and external connector) on a single SCSI host adapter card. Such a configuration is a violation of the SCSI specification. You can safely connect devices to any two of these three connectors on a single SCSI host adapter card. |
If you are installing only internal SCSI devices, verify that termination is enabled on the SCSI host adapter and disabled for all other internal SCSI devices. If you are installing both internal and external SCSI devices, verify that termination is enabled on the external SCSI device and disabled for the SCSI host adapter and all internal SCSI devices.
|
CAUTION: To avoid the possibility of electric shock, turn off the computer and any peripherals, disconnect them from their electrical outlets, and then wait at least 5 seconds before you remove the computer cover. Also, before you install an expansion card, see "Safety First — For You and Your Computer." |
Configure and install one or more SCSI devices in your computer as follows:
NOTICE: 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, if necessary, enable or disable termination. For instructions, see the documentation that came with the SCSI device and "SCSI Configuration Guidelines."
For instructions on configuring the card, see the documentation that came with the adapter card and "SCSI Configuration Guidelines."
- To install an internal SCSI hard-disk drive, complete steps 3 through 7 of "Installing an EIDE Hard-Disk Drive in the Hard-Disk Drive Bracket." Then continue with step 5 of this procedure.
- To install a SCSI tape drive, CD-ROM drive, or DAT drive, complete steps 2 through 6 of "Installing a Drive in a 5.25-Inch Drive Bay." Then continue with step 5 of this procedure.
- To install an external SCSI tape drive, continue with step 5 of this procedure.
See "Installing an Expansion Card."
If a SCSI host adapter card is already installed, remove, reconfigure, and reinstall the card at this time. See the documentation that came with the SCSI host adapter card, "Removing an Expansion Card," and "Installing an Expansion Card."
Connect the hard-disk drive access cable to the SCSI host adapter card and to the HDLED connector on the riser board (see "Riser-Board Expansion-Card Connectors"). This cable carries a signal from the SCSI host adapter card to the hard-disk drive access indicator on the computer's front panel whenever one of the SCSI hard-disk drives is accessed.
NOTICE: 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 additional instructions on connecting SCSI devices, see "
SCSI Cable and SCSI Termination."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.
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.
NOTICE: You must match the colored strip on the internal SCSI cable with pin 1 on the adapter card connector to avoid possible damage to your system.
For additional instructions, see the documentation that came with the adapter card.
Check all other cable connections. Fold all internal cables out of the way to provide airflow for the fan or cooling vents.
See "Removing and Replacing Front-Panel Inserts" for instructions.
|
NOTE: If the device you just installed is the primary hard-disk drive and no operating system is installed, you must start the computer using a bootable diskette or CD. |
|
NOTE: If Enabled, the Chassis Intrusion option will cause the following message to be displayed at the next system
start-up: ALERT! Cover was previously removed. |
|
NOTE: Tape drives attached to a SCSI host adapter card are not part of the system configuration information. |
After you update the System Setup options, reboot the system.
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: On systems with hard-disk drives larger than 2 GB, create a primary partition of 2 GB and divide the remaining capacity into partitions of 2 GB or less. For example, a system with a 2.5-GB hard-disk drive would have a primary partition of 2 GB (drive C) and a second partition of 500 MB (drive D). Hard-disk drives must be partitioned this way because MS-DOS-based operating systems (including Windows NT when you use a FAT 16 file system) do not support drive partitions larger than 2 GB. |
