Attention:
v When you route cables, do not block any connectors or the ventilated space
around any of the fans.
v Make sure that cables are not routed on top of components that are under
the PCI riser-card assembly.
v Make sure that cables are not pinched by the server components.
9. Rotate the retention latch to the closed position, making sure the retention
latch engages the ServeRAID adapter. Then, push in the release pin to lock
the retention latch in place.
10. Install PCI riser-card assembly 2 (see “Installing the PCI riser-card assembly”
on page 90).
If you have other devices to install or remove, do so now. Otherwise, go to
“Completing the installation” on page 89.
Notes:
1. When you restart the server for the first time after you install a ServeRAID
adapter 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 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 adapter.
Installing a ServeRAID adapter battery on the remote battery tray
The Intelligent Battery Backup Unit (iBBU) is an optional battery for the ServeRAID
adapter. It is referred to as the battery throughout this section. You must purchase
the remote battery cable and install the battery at a distance from the ServeRAID
adapter to avoid overheating.
You can install up to two batteries on the remote battery trays on the PC riser-card
assembly.
To install a battery on the remote battery tray, complete the following steps:
1. Read the safety information that begins on page vii and “Installation guidelines”
on page 35.
2. Turn off the server and peripheral devices and disconnect all power cords and
external cables (see “Turning off the server” on page 24).
3. Remove the server top cover (see “Removing the server top cover” on page
44).
4. Install the battery in the RAID battery tray:
a. Orient the battery as shown in the following illustration; then, lower the
battery into the RAID battery tray. If the battery comes with a battery carrier,
ensure that battery carrier posts align with the rings on the battery mounting
slot so that the battery carrier is secure in the slot.
