Chapter 6: Advanced Chassis Setup
Replacing the Power Supply
1. Accessing the inside of the system
To replace a power supply, you must fi rst remove the top chassis cover. To do so, fi rst release the retention screws that secure the unit to the rack. Grasp the two handles on either side and pull the unit straight out until it locks (you will hear a "click"). Next, remove the screws from the lips on either side of the cover then depress the two buttons on the cover to release it. Push the cover away from you then lift it from the chassis to gain full access to the inside of the server (see Figure
2. Removing the power supply
First unplug the power cord from the system. To remove the failed power unit, remove the two screws on the back of the power supply and a third from the front of the power supply, which secures it to the bottom of the chassis. You can then lift the unit straight out of the chassis. (The power cord should have already been removed.)
3. Installing a new power supply
Replace the failed unit with another unit of the same wattage. It is highly recom- mended to replace it with the exact same power supply. Carefully insert the new unit into position in the chassis and secure it with the two screws at the rear of the unit and the third at the front. Then reconnect the power cord, replace the chassis top cover and push the unit back into the rack. Finish by turning the power switch on the power supply on, and then depress the power button on the front of the system.
