describes the jumpers and the connectors
on the SAS 9280-4i4e RAID controller.
Table 1
SAS 9280-4i4e Jumpers and Connectors
Note:
J6A1 is behind the iBBU when it is installed
directly, but it is still accessible.
Step 4
Install the RAID Controller
Insert the RAID controller in a PCI Express slot
on the motherboard, as shown in
. Press
down gently, but firmly, to seat the card correctly
in the slot. Secure the RAID controller to the
computer chassis with the bracket screw.
Note:
Some PCI Express slots support only PCI
Express graphics cards; if a RAID controller is
installed, it will not function.
Note:
This controller also works in PCI Express first
generation slots. The PCI Express software is
backward compatible with previous revisions of
the PCI bus and the PCI-X bus. For information
about the PCI Express slot, refer to the guide for
your motherboard.
