WARNING: To reduce the risk of personal injury or damage to the equipment, consult the safety
information and user documentation provided with the server before attempting the installation.
Some servers contain high energy, high circuits, moving parts (such as fan blades), or any
combination of these hazards, that may be exposed if covers and access panels are removed
while the product is powered. These products are intended to be serviced only by qualified
personnel who have been trained to deal with these hazards. Do not remove enclosures or
attempt to bypass any interlocks that may be provided for the purpose of guarding against these
hazardous conditions.
1. Remove or open the access panel.
WARNING: To reduce the risk of personal injury from hot surfaces, allow the drives and the
internal system components to cool before touching them.
2. Select an available x8 or larger PCIe expansion slot.
A x8 physical size slot is required, even though the slot may run at a x4 or x1 speed.
3. Remove the slot cover. Save the retaining screw, if one is present.
4. Install the cache module, as needed.
For some controllers, if the cache module is absent, the controller does not function.
5. Slide the controller board along the slot alignment guide, if one is present, and then press the board
firmly into the expansion slot so that the contacts on the board edge are seated properly in the slot.
6. Secure the controller board in place with the retaining screw. If the slot alignment guide has a latch
(near the rear of the board), close the latch.
7. Connect internal storage devices to the controller, if necessary. For more information, see "Connecting
internal storage (on page 39)."
8. Close or install the access panel, and then 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.
Connecting internal storage
1. Power down the server.
2. Install drives, if necessary. For drive requirements when configuring arrays, see "Array configuration
tools (on page 44)."
The server and controller may support different types of drives. However, all drives grouped in a logical
drive must meet the following criteria:
o They must be either SAS or SATA.
o They must be either all hard drives or all solid state drives.
o For the most efficient use of drive space, the drives must have comparable capacity.
For more information about drive installation, see the following resources:
o Drive procedures (on page 79)
o Server documentation
o Drive documentation
3. Use the internal SAS cable provided with the server to connect the controller to the drives:
