2: System Operation
(toward the rear of the chassis) until it stops. You can then lift the top cover from the chassis to
gain full access to the inside of the server (see Figure 2-4).
To remove the system completely from the rack, depress the locking tabs in the chassis rails (push
the right-side tab down and the left-side tab up) to continue to pull the system out past the locked
position.
Checking the Components and Setup Before Power On
If any internal modifications have been made to the server prior to installation in the rack, you may
wish to recheck the server’s interior.
You may have one or two processors already installed on each of the two serverboards. Each
processor needs its own heatsink.
Your server comes with system memory already installed. Make sure all DIMMs are fully seated
in their slots. For details on adding system memory, refer to Chapter 4.
You can install two add-on cards to the system.
Make sure all power and data cables are properly connected and not blocking the chassis airflow.
Checking the Hard Disk Drives
The system disk drives are accessable from the front of the server and can be installed and
removed from the front of the chassis without removing the top chassis cover.
Depending upon your system's configuration, your system will have one or more drives already
installed.
Checking the Airflow
Airflow through the server is provided by an air shroud and three sets (six fans back to back) of
4-cm counter-rotating PWM fans per node board [for a total of two air shrouds and six sets of fans
(12 total) in the system]. The system component layout was carefully designed to direct sufficient
cooling airflow to the components that generate the most heat.
