Chapter 1 Installation Overview To remove the covers, refer to Figure 1-1 and do the following: 1. Turn off the HP NetServer and disconnect the power cord. WARNING Before removing the cover, always disconnect the power cord and unplug telephone cables. This action helps avoid exposure to high energy levels that may cause burns when parts are short-circuited by metal objects such as tools or jewelry, as well as exposure to shock hazard from telephone ringing voltages. Note that the power switch does NOT turn off the standby power. Disconnect the power cord from the HP NetServer to turn off the standby power before handling components. CAUTION Wear a wrist strap and use a static-dissipating work surface connected to the chassis when handling components. 2. Unlock the front bezel with the key in the key bag located on the rear of the HP NetServer. 3. Remove the front bezel (See Figure 1-1, Step A.): a. Pull on the pocket on the side of the front bezel to swing that side of the bezel outward. b. Pull the front bezel off the HP NetServer. This exposes the thumbscrews on the top cover. 4. Remove the top cover: a. Loosen both thumbscrews on the front of the HP NetServer. (See Figure 1-1, Step B.) b. Pull the front of the top cover forward 1/16 inch (1.5 mm), and then lift the front up only far enough to create a gap of 1 inch (3 cm) between the top cover and the chassis. CAUTION Only lift the front of the top cover high enough to create a gap of 1 inch (3 cm) between the top cover and the chassis. Lifting the top cover higher can damage it and the chassis. (See Figure 1-1, Step C.) 4
