Chapter 2: Server Installation 2-5 Checking the Motherboard Setup After you install the 6040 in the rack, you will need to open the unit to make sure the motherboard is properly installed and all the connections have been made. 1. Accessing the inside of the 6040 (see Figure 2-5): First, release the retention screws that secure the unit to the rack. Next, release the two thumbscrews that secure the top cover to the chassis. Grasp the two handles on either side and pull the unit straight out until it locks (you will hear a "click"). There are two square recesses in the top cover to help you push the cover away from you until it stops. You can then lift the top cover from the chassis.
You now have full access to the inside of the server. 2. Check the CPUs (processors): You should have one or two processors fully inserted into the system board. If one CPU is used, install the CPU into CPU Socket 1 (see Pg.5- 10). Inadequte ventilation or improper installation of the CPU heat sinks may result in the instability of the system. When installing the heat sinks, use the proper type of thermal glue and apply the proper amount of thermal glue on the die of the CPU. improper type or amount of thermal glue used on the die of the CPU and improper installation of the heat sink may result in the crash of the system. 3. Verify the proper CPU core/bus ratio setting:
You need to verify that the CPU core/bus ratio as set with DIP Switch 1 matches the speed of your installed processors. This DIP Switch is defaulted to 5.5, which corresponds to 550 MHz processors running on a 100 MHz front side bus (FSB). If the setting is different or if you are using processors of a different speed, you may need to change this setting. 4. Check all cable connections and airflow: Make sure all power and data cables are properly and firmly connected and not blocking the airflow. 2-7
