HP Integrity rx4640 Server - Manual (Page 11)

Installing the controller hardware 11
1. Remove or open the access panel.
2. Select an available 3.3-V PCI or PCI-X slot.
3. If the controller is being hot-plugged, power down the slot.
4. Remove the slot cover or open the hot-plug latch. Save the retaining screw if one is present.
5. Slide the controller board along the slot alignment guide, and press the board firmly into the slot so
that the contacts on the board edge are properly seated in the system board connector.
6. Secure the controller board in place with the hot-plug latch or retaining screw. If there is a guide
latch on the rear of the board, close the latch.
7. To finish installing the hardware, connect the internal and external drives (" Connecting storage
devices " on page 11 ).
NOTE: Drives that are to be grouped in the same array should all have comparable capacity for efficient
use of total storage capacity.
8. Close or replace the access panel, and secure it with thumbscrews, if any are present.
CAUTION: Do not operate the server for long periods with the access panel open or removed. Operating
the server in this manner results in improper airflow and improper cooling that can lead to thermal damage.
9. If the controller was hot-plugged, power up the slot.
Connecting storage devices
The controller supports Ultra2, Ultra160 (Ultra3), and Ultra320 drives.
Each peripheral that is connected to the controller must have a unique SCSI ID value within the range of 0
to 15 (except ID 7, which is reserved for controller use). This value determines the priority that is given to
the device when it attempts to use the SCSI bus.
The system automatically sets the SCSI IDs for hot-pluggable devices if they are supported. For non-hot-
pluggable devices, you must set the ID values manually by using switches or jumpers on the device itself.
SCSI buses require termination on both ends to prevent signal degradation. In HP ProLiant and Integrity
servers, however, the controller, SCSI cable, and backplane already provide this termination.
Connecting internal storage
1. If the storage device that you are adding is not hot-pluggable, power down the system.
2. Install drives in the removable media bays on the server.
CAUTION: Do not use hot-pluggable drives on the same SCSI bus as non-hot-pluggable drives.
NOTE: Drives that are to be grouped in the same array should all have comparable capacity for efficient
use of total storage capacity.
For additional information about drive installation, refer to the appropriate section in this guide
("
Replacing, moving, or adding hard drives " on page 22 ) and consult the documentation that
accompanied the drives.
When you have finished installing drives, continue with the next step.
• If the drives are hot-pluggable, go to step 3.
• If the drives are not hot-pluggable, go to step 4.
3. Attach the internal point-to-point SCSI cable (provided with the server) from the internal connector of
the controller to the hot-plug drive cage.
Installation of the hot-pluggable drives is complete.
