Chapter 3 NOTE Perform the Upgrade After you unlock the power interlock switch, there is no power present at any internal or externally accessible area of the satellite chassis. However, five volts of power are present at the power supply pins on the base chassis where the satellite attaches. To remove all power, unplug the AC power cord. Slide Out the Satellite Chassis CAUTION Wear a wrist strap and use a static-dissipating work surface connected to the chassis when handling components. Ensure that the metal of the wrist strap contacts your skin. 1. Put on the antistatic wrist strap and place the antistatic mat on a firm surface near the system. Connect the strap and mat to an unpainted metal surface on the system chassis. 2. Look at any cables you might have connected to PCI cards. If there is not enough slack in one or more cables to pull out the satellite chassis, disconnect the cables as necessary. 3. Remove the retention bracket from the lower rear of the NetServer and set it aside. See Figure 3-3. CAUTION You will need to replace the retention bracket when redocking the Satellite Chassis. The bracket ensures correct mechanical connection. 9
