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.
