Chapter 2: Server Installation 2-5 Checking the Motherboard Setup After you install the 8060 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 8060 (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): The processors are enclosed in an air shroud. You should one to four processors fully inserted into the system board. Each processor should have its own heatsink attached. See Section 5-4 for instruc- tions on processor installation. 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. (See Section 5-8 for setting the core/bus ratio with DIP Switch 1.) 4. Check the MEC: The Memory Expansion Card (MEC) should be already installed. Make sure the MEC is fully seated in its slot and that its retention plate is screwed firmly to the chassis. For details on populating the MEC, refer to Section 5-5. 5. Installing add-on cards: Install any add-on cards that you want added to the system. See Section 5-6 for details on installing PCI add-on cards. 6. Check all cable connections and airflow:
Make sure all power and data cables are properly and firmly connected and not blocking the airflow. See Section 5-3 for details on cable connections. 2-7
