System Overview 1-29
Figure 1-15 shows the distribution of power throughout the system. Opens in the
circuit or the RCM signal RCM_DC_EN_L, or a power supply detected power fault
interrupt DC power applied to the system. The opens can be caused by the On/Off
button or the cover interlock.
A failure anywhere in the circuit will result in the removal of DC power. A potential
failure is the relay used in the RC logic to control the RCM_DC_EN_L signal.
The cover interlock is located under the top cover between the system card cage and
the storage area. To override the interlock, place a suitable object in the interlock
switch that closes it.
