Your system features an internal drive bay that contains up to six 1-inch hard drives. Your system also features a removable peripheral bay that incorporates two drive bays for installing two additional hard drives or an internal tape drive. Attached to the removable periperal bay is a user-assessable, half-height, CD drive and a 3.5-inch diskette drive, which is controlled by the IDE/diskette drive controller on the system board.
This section contains instructions for:
Installing and configuring hard drives in the internal drive bay
Installing an external SCSI tape drive
Activating the integrated RAID controller
Installing a RAID controller card
Installing an optional SCSI backplane daughter card for split backplane operation
Hard drives are supplied in special drive carriers that fit in the hard-drive bays.
NOTICE: Before attempting to remove or install a drive while the system is running, see the
documentation for the host adapter to ensure that the host adapter is configured correctly to
support hot-pluggable drive removal and insertion.
NOTICE: Do not turn off or reboot your system while the drive is being formatted. Doing so can
cause a drive failure.
NOTE: Only use drives that have been tested and approved for use with the SCSI
backplane board.
When you format a high-capacity hard drive, allow enough time for the formatting to be completed. Long format times for these drives are normal. For example, an exceptionally large drive can take over an hour to format.
After the SCSI devices are installed, install and configure any SCSI device drivers to enable them to communicate with your operating system.
SCSI device drivers are provided for the following operating systems:
Microsoft® Windows NT® 4.0 Server, Enterprise Edition
Microsoft Windows® 2000 Server and Advanced Server
Red Hat Linux 7.2 or later
Novell® NetWare® 5.0 or later
See "Using the Dell OpenManage Server Assistant CD" in the User's Guide for instructions on creating a diskette of drivers for your operating system. For instructions on configuring the SCSI device drivers, see the documentation that came with your operating system.
The hard-drive bays provide space for up to six 1-inch hard drives. The hard drives connect to a controller on the system board or a RAID controller card through the SCSI backplane board.
The system provides several options for hard drive configurations:
If a RAID controller card is not installed, additional cables are not required to use either the onboard SCSI controller or optional integrated RAID controller in either a 1 x 6 or 2 x 3 split configuration.
If a RAID controller card is installed, cables can be connected from the controller card to SCSI A and/or SCSI B backplane board connector(s). A backplane board connector that is not attached to the RAID controller card will use the onboard SCSI controller or optional integrated RAID controller.
If a cable is connected to the SCSI B backplane board connector, the SCSI backplane daughter card must be installed to activate the 2 x 3 split configuration. Otherwise, the system will display an error message.
See Figure A-4 to locate the connectors on the SCSI backplane board.
NOTICE: Not all operating systems support hot-plug drive installation. See the documentation
supplied with your operating system.
Remove the bezel (see "Removing the Bezel" in "Troubleshooting Your System").
Take the hard drive offline and wait until the hard-drive indicator codes on the drive
carrier signal that the drive may be removed safely (see Table 2-6).
If the drive has been online, the drive status indicator will blink green two times a second as the drive is powered down. When all indicators are off, the drive is ready for removal.
See your operating system documentation for more information on taking the hard drive offline.
Open the hard-drive carrier handle to release the drive (see Figure 7-1).
Figure 7-1. Removing and Installing a Hard-Drive
Slide the hard drive out until it is free of the drive bay (see Figure 7-1).
If you are permanently removing the hard drive, install a blank insert.
Replace the bezel (see "Replacing the Bezel" in "Troubleshooting Your System").
NOTICE: When installing a hard drive, ensure that the adjacent drives are fully installed.
Inserting a hard-drive carrier and attempting to lock its handle next to a partially installed
carrier can damage the partially installed carrier's shield spring and make it unusable.
NOTICE: Not all operating systems support hot-plug drive installation. See the documentation
supplied with your operating system.
Remove the bezel (see "Removing the Bezel" in "Troubleshooting Your System").
Open the hard-drive carrier handle (see Figure 7-1).
NOTICE: Do not insert a hard-drive carrier and attempt to lock its handle next to a partially
installed carrier. Doing so can damage the partially installed carrier's shield spring and make it
unusable. Ensure that the adjacent drive carrier is fully installed.
Insert the hard-drive carrier into the drive bay (see Figure 7-1).
Close the hard-drive carrier handle to lock it in place.
Replace the bezel (see "Replacing the Bezel" in "Troubleshooting Your System").
You must connect external SCSI devices to a SCSI host adapter expansion card. See "Expansion Cards" in "Installing System Options" for information about installing expansion cards.
SCSI interface connectors are keyed for correct insertion. Keying ensures that the pin-1 wire in the cable connects to pin 1 in the connectors on both ends.
When you disconnect an interface cable, take care to grasp the cable connector, rather than the cable itself, to avoid stress on the cable.
Although SCSI devices are installed in essentially the same way as other devices, their configuration requirements are different. To configure an external SCSI device, follow the guidelines in the following subsections.
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. For internal SCSI devices, termination is configured automatically. For external SCSI devices, you should disable termination on all devices and use terminated cables. See the documentation provided with any optional SCSI device you purchase for information on disabling termination.
CAUTION: See "Protecting Against Electrostatic Discharge" in the safety
instructions in your System Information document.
Open the bezel (see "Removing the Bezel" in "Troubleshooting Your System").
Turn off the system, including any attached peripherals, and disconnect the system
from the electrical outlet.
Prepare the tape drive for installation.
Ground yourself by touching an unpainted metal surface on the back of the system, unpack the drive (and controller card, if applicable), and compare the jumper and switch settings with those in the drive documentation.
See "SCSI Configuration Information," for information on setting the drive's SCSI ID number and enabling termination (if required). Change any settings necessary for your system's configuration.
