Figure 36. ServeRAID adapter installation
Attention: Incomplete insertion might cause damage to the server or the adapter.
Step 7. Connect any required cables to the ServeRAID adapter.
Attention:
• When you route cables, do not block any connectors or the ventilated space around any of
the fans.
• Make sure that cables are not routed on top of components that are under the PCI riser-card
assembly.
• Make sure that cables are not pinched by the server components.
Step 8. Rotate the retention latch to the closed position, making sure the retention latch engages the
ServeRAID adapter. Then, push the release pin to lock the retention latch in place.
Step 9. Install PCI riser-card assembly 1 or 2 (see "Installing a PCI riser-card assembly" on page 75.
If you have other devices to install or remove, do so now. Otherwise, go to "Completing the installation"
on page 73.
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.
