Replacing the RAID 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 “Installation guidelines”
on page 29.
2. Turn off the server and peripheral devices and disconnect all power cords and
external cables (see “Turning off the server” on page 12).
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 “Removing the cover” on page 31).
4. Remove the riser-card assembly and the air baffle over the DIMMs (see
“Removing the DIMM air baffle” on page 37).
5. Locate the ServeRAID-8k-l SAS controller on the system board (see
“System-board optional-device connectors” on page 18).
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.
