Lenovo 6444, 6447, 6446, 6445 manual Replacing the ServeRAID SAS controller

Replacing the ServeRAID SAS controller

A ServeRAID SAS controller can be installed only in a dedicated slot on the system board. The server comes with a ServeRAID-8k-l SAS Controller installed.

Note: The ServeRAID-8k-l SAS Controller does not have a battery.

To replace the ServeRAID-8k-l SAS Controller with a ServeRAID-8k SAS Controller, complete the following steps:

1.Read the safety information that begins on page v and the “Installation guidelines” on page 7.

2.Turn off the server and peripheral devices and disconnect all power cords and external cables (see “Turningoff the server” on page 39).

Attention: In a dc power environment, only trained service personnel other than Lenovo service technicians are authorized to connect or disconnect power to the dc power supply. See the documentation that comes with each dc power supply.

3.Remove the cover (see “Removingthe cover” on page 9).

4.Remove the riser-card assembly and the air baffle over the DIMMs. See the User Guide for more information.

5.Locate the ServeRAID-8k-l SAS controller on the system board.

Attention: To avoid breaking the retaining clips or damaging the connectors, handle the clips gently.

6.Open the retaining clip on each end of the connector.

7.Lift the ServeRAID-8k-l SAS controller out of the connector.

8.Touch the static-protective package that contains the new ServeRAID-8k SAS controller to any unpainted metal surface on the server. Then, remove the ServeRAID-8k SAS controller from the package.
