System Features
Power Supply
Power Connectors
Main power is applied to the Lion through a 12-pin polarized connector (J19), with mating
connector Molex 55959-1230 (housing) + Molex 51353-1200 (pins). See Table 7 for connector
pinout.
CAUTION:
To prevent severe and possibly irreparable damage to the system, it is critical that the
power connectors are wired correctly. Make sure to use all +5 V
DC
pins and all ground
pins to prevent excess voltage drop. The power connector is not fuse or diode
protected. Proper polarity must be followed otherwise damage will occur.
