8. Install the SAS riser-card and controller assembly (see "Installing the SAS
riser-card and controller assembly" on page 92).
If you have other devices to install or remove, do so now. Otherwise, go to
"Completing the installation" on page 106.
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 are given the opportunity to import the existing
RAID configuration to the new ServeRAID SAS controller.
The Intelligent Battery Backup Unit (iBBU) is an optional battery for the
ServeRAID-MR10i SAS/SATA controller and a standard battery for the
ServeRAID-MR10M SAS/SATA controller. It is referred to as the battery throughout
this section.
When you install a ServeRAID SAS controller in a PCI riser-card assembly in the
server, you must install the battery at a distance from the ServeRAID controller to
avoid overheating. This section describes the process for installing a battery or
batteries in the server.
To install a battery, complete the following steps:
1. Read the safety information that begins on page vii and "Installation guidelines"
on page 36.
2. Turn off the server and peripheral devices and disconnect all power cords and
external cables (see "Turning off the server" on page 21).
3. Remove the cover (see "Removing the cover" on page 43).
4. Remove the PCI riser-card assembly from the server and set it aside (see
"Removing a PCI riser-card assembly" on page 44).
5. Remove the ServeRAID controller from the riser card (see "Removing a PCI
adapter" on page 54).
