4. Unlock the power interlock switch at the HP NetServer's rear by turning it
clockwise (Figure 2-3). The switch also 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.
