Moving The Sas-Controller Retention Bracket - Lenovo ThinkServer RD220 Hardware Maintenance Manual

Step 5. Turn the SAS controller so that the keys on the bottom edge align correctly with the connector on
the SAS riser card in the SAS controller assembly.
Step 6. Firmly press the SAS controller horizontally into the connector on the SAS riser card.
Step 7. (Tape-enabled model server only) Gently press the opposite edge of the SAS controller into the
controller retention bracket.
Step 8. Install the SAS riser card and controller assembly (see Removing the SAS riser card and controller
assembly).
If you have other optional devices to install or remove, do so now. Otherwise, go to "Completing the
installation" on page 202.
Notes:
1. When you restart the server for the first time after you install a SAS controller with a battery, the monitor
screen remains blank while the controller initializes the battery. This might take a few minutes, after which
the startup process continues. This is a one-time occurrence.
Important: You must allow the initialization process to be completed. If you do not, the battery pack will
not work, and the server might not start.
The battery comes partially charged, at 30% or less of capacity. Run the server for 4 to 6 hours to
fully charge the controller battery. The LED just above the battery on the controller remains lit until
the battery is fully charged.
Until the battery is fully charged, the controller firmware sets the controller cache to write-through mode;
after the battery is fully charged, the controller firmware re-enables write-back mode.
2. When you restart the server, you will be given the opportunity to import the existing RAID configuration to
the new SAS controller.
