Installing the ThinkServer 8708ELP SAS RAID Adapter
Attention: Do not open your server or attempt any repair before reading and understanding the “Safety information”
on page iii and “Guidelines” on page 19.
This section provides instructions on how to install the ThinkServer 8708ELP SAS RAID Adapter (hereafter
referred to as the RAID controller within this section).
Notes:
1. If your server is shipped with a RAID card retention bracket, follow the instructions in this section to
install or remove the RAID controller.
2. If your server is shipped without a RAID card retention bracket, you have to install a RAID card retention
bracket on the riser card assembly before you install or remove the RAID controller. For instructions on
how to install the RAID card retention bracket, refer to the Important Information about the RAID Card
Retention Bracket (PN: 0A91937) that comes with your RAID controller option package.
3. The RAID card retention bracket might look different from the illustrations in this section.
4. Use any documentation that comes with the RAID controller and follow those instructions in addition to
the instructions in this section.
To install the RAID controller, do the following:
1. Remove all media from the drives and turn off all attached devices and the server. Then, disconnect all
power cords from electrical outlets and disconnect all cables that are connected to the server.
2. Remove the server cover. See “Removing the server cover” on page 21.
3. Touch the static-protective package that contains the RAID controller to any unpainted surface on the
outside of the server. Then, remove the RAID controller from the package.
4. Depending on your RAID controller, you might need to install a ThinkServer 8708ELP SAS RAID
adapter battery (hereafter referred to as the battery card assembly) on the RAID controller. The battery
card assembly mounts directly to the RAID controller through a small board-to-board connector
(daughtercard).
