Unlock the power interlock switch at the back of the HP NetServer's rear panel by turning it clockwise (Figure 2-5). The switch turns off DC power to the HP NetServer, and also unlocks the satellite chassis. See the HP NetServer LXr Pro8 User Guide for more details on opening and closing the HP NetServer chassis. NOTE After you unlock the power interlock switch, DC power is turned off for all components within the satellite chassis except for five volts at the system control board which is located on the SCSI Extender Tray in the bottom of the lower board cage area. If you undock the satellite chassis from the base unit, there is no power present at any internal or externally-accessible area of the satellite chassis. However, five volts are still present at the power supply connector where the satellite chassis attaches. To remove all power, unplug the AC power cord. 9
