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").

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 Figure6-1).
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.
