N2125 SAS/SATA HBA for IBM System x Hardware User’s Guide
Hardware Installation
To install the HBA, follow these steps:
1.
Unpack the HBA, and inspect it for damage.
Unpack the HBA in a static-free environment. Touch the
static-protective package that contains the HBA to any unpainted surface on the outside of the server; then, grasp
the HBA by the top edge or upper corners, remove it from the package, and inspect it for damage. Contact your
IBM marketing representative or authorized reseller if the HBA appears to be damaged.
2.
Prepare the server.
Turn off the server, and disconnect the power cord from the rear of the power supply.
3.
Remove the cover from the chassis.
4.
Replace the HBA mounting bracket (system dependent).
If required for your system, replace the full-height
mounting bracket that ships on the HBA with the low-profile bracket supplied. Save and reuse the two screws
that attach the long bracket to attach the short bracket.
5.
Insert the HBA in an available PCIe slot.
Locate an empty x8 PCIe slot and remove the expansion-slot cover for
the selected PCIe slot. Save the bracket screw, if applicable. Align the HBA with the PCIe slot and press down
gently, but firmly, to correctly seat the HBA in the slot. The following figure shows how to insert the HBA in a PCIe
slot.

6.
Secure the HBA bracket to the system chassis.
Install the bracket screw, if applicable, or engage the system
retention mechanism to secure the HBA to the system chassis.
7.
Connect SAS cables between the HBA and any SAS enclosures that contain the SATA or SAS devices.

shows the locations of the HBA
connectors. The HBA has two external x4 mini-SAS connectors. For external connections, use a cable with an
external mini-SAS connector (SFF-8088) on one end (to connect to the HBA) and the appropriate connector to
attach to the SAS or SATA devices on the other end.
ATTENTION
Make a backup of your data before changing your system configuration to avoid the risk of
data loss.
NOTE
The shape, size, and locations of components on your HBA and its bracket might vary from this
illustration. This HBA requires a x8 PCIe slot.
