c. Connect the ServeRAID-8k SAS controller battery to the ServeRAID SAS
controller.
5. Replace the air baffle over the DIMMs (see “Installing the DIMM air baffle” on
page 62).
6. Replace the riser-card assembly.
7. Install the cover (see “Installing the cover” on page 57).
8. Slide the server into the rack.
9. Reconnect the external cables; then, reconnect the power cords and turn on the
peripheral devices and the server.
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.
Notes:
1. When you restart the server for the first time after you install a ServeRAID-8k
SAS controller, 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 ServeRAID SAS controller.
