To install the RAID controller, do the following:

Note: Use any documentation that comes with the RAID controller and follow those instructions in addition to the instructions in this topic.

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 19.

3.Remove the riser card assembly. See “Removing the riser card” on page 33.

4.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.

5.Depending on your RAID controller, you might need to install a ThinkServer RAID 700 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).

Notes:

a.The battery card assembly protects the integrity of the cached data on the RAID controller by providing backup power up to 72 hours in the case of a complete ac power failure or a brief power outage. It has built-in functionality to charge the battery pack automatically and to communicate battery status information such as voltage, temperature, and current to your server. It also provides an inexpensive alternative to using an uninterruptible power supply, and a second level of fault tolerance when used in conjunction with an uninterruptible power supply. For more information about the battery card assembly, see Appendix A “RAID battery card assembly” on page 97.

b.The battery card assembly option kit contains a user guide, the battery card assembly, and three Phillips-head screws. Do not remove the battery card assembly from the antistatic shipping container until you are ready to install it. When you remove the battery card assembly from your server, place it in its original container.

c.Check the appropriate support Web sites for the latest updates for your basic input/output system (BIOS) code, utility programs, device drivers, and other software applications. Follow the instructions provided by your Service Provider to download and install updates.

d.It is recommended that you replace the battery pack on the battery card assembly annually or after 500 recharging cycles, whichever comes first.

e.The temperature of the battery card assembly is generally 15-20°C (59-68°F) higher than the ambient temperature during fast charge. Therefore, to complete a fast charge cycle, the ambient temperature should be lower than 45°C (113°F). If the ambient temperature exceeds 45°C (113°F), the fast charge cycle will terminate prematurely, thus preventing the battery card assembly from reaching a fully charged state.

Attention:

•When attaching the battery card assembly to a PCI Express slot, center the Phillips-head screw driver to avoid damaging the screw head and do not over-tighten the screws as you might damage the battery card assembly.

•The battery in the battery card assembly must recharge for at least six hours during fast charge under normal operating conditions.

To install the battery card assembly onto the RAID controller, do the following:
