for removal.
3. Open the front bezel (see "Removing the Front Bezel" in "Troubleshooting Your System").
4. Open the drive carrier handle to release the carrier.
5. Slide the carrier toward you until it is free of the drive bay.
6. Close the front bezel.
Installing a Dell Host Adapter Card
Follow these general guidelines when installing a Dell host adapter card. For specific instructions, see the documentation supplied with the host adapter card.
1. Unpack the host adapter card, and prepare it for installation.
See the documentation accompanying the host adapter card.
2. Open the front bezel (see "Removing the Front Bezel" in "Troubleshooting Your System").
3. Remove the system cover.
4. Remove the SCSI interface cable that connects the SCSI/Channel A host-adapter connector on the system board to the SCSIA connector on the SCSI
backplane board (see Figure6-1).
5. Install the host adapter card.
If you are installing a Dell PERC host adapter card, install the card in PCI expansion slot 1.
6. Install the SCSI interface cable supplied with the host adapter card to the SCSIA connector on the SCSI backplane board.
To identify the correct connector, see documentation for the host adapter card. Route the SCSI cable under the front fan assembly.
7. Connect the external SCSI devices to the SCSI host adapter card's external connector on the system's back-panel.
If you are attaching multiple external SCSI devices, daisy-chain the devices to each other by using the cables shipped with each device.
8. Replace the system cover.
9. Close the front bezel. Reconnect the system to an electrical outlet.
10. Connect the external device(s) to electrical outlet(s).
11. Install any required SCSI device drivers (see "Installing and Configuring SCSI Drivers," in the User's Guide for information and instructions).
12. Test the SCSI devices.
Test a SCSI hard-disk drive by running the SCSI Controllers test in the Dell Diagnostics. To test a SCSI tape drive, also see the documentation for the tape drive
software to perform a tape drive backup and verification test.
Installing a SCSI Backplane Daughter Card
To operate the SCSI backplane in a 2 x 3 split backplane configuration, you must install an optional daughter card.
1. Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.
2. Unpack the SCSI backplane board daughter card kit.
